Designing for Smart Fabrics: Wear It’s At – Part 3

In Part 1 of this series, we looked at defining smart fabrics. In Part 2, we looked at some design ideas. In Part 3 we will explore things that could go wrong with this technology, and offer up two possible futures for products using smartfabric tech.

What are the Potential Drawbacks?

If we can access, visualize and interact with our digital lives with fabric, that brings a whole set of implications to design for (privacy, security, etc.) and the challenges of displaying and interacting with systems.

Imagine the possibilities. We will soon have clothing with:

  • built in displays that can show you information, images and video you would normally see on a PC or smartphone screen.
  • interaction with a system using certain gestures by touching your clothing.
  • powerful, tiny sensors that monitor biological functions.

Pretty cool huh? These technologies are currently being developed, and they could open the door to some fantastic possibilities. They also have a darker side, with potential pitfalls.

The most obvious pitfall is to needlessly annoy the wearer with notifications or prompts to interact with their clothing. Over notifying can over stimulate our senses. If vibration or lighting/color changes are used to get our attention, this might be useful if it is used sparingly. If we get a lot of buzzes against our skin, or our clothing rapidly is changing color or displays or lights are blinking at us too much, smartfabrics products could make people sick.

Accidental interactions can cause unintended results. What if I can control my TV shows with my jeans by gesturing on the fabric, but every time I change positions in my chair, I change the channel? Controlling inputs, determining touch targets and gestures, as well as what to display, and how to notify people of events are difficult to implement well on something that is constantly touching your skin. Over-notify and people will want to destroy their clothing, tickle people and they will go crazy.

Target areas for inputs and outputs are important to consider in clothing design. Inputs and outputs need to be placed very carefully on the body. They could draw unwanted attention to a particular area of the wearer’s body. Even if they aren’t highlighting private parts, they may trigger body image issues if it highlights a perceived flaw in the wearer. It’s also easy to imagine accidental or even purposeful unwanted touching – someone could use the input as an excuse to touch you. If the design encourages interaction, it could be easy for someone to be compelled to touch you when they normally wouldn’t. Inadvertently encouraging unwanted touching in our designs could have very serious implications. Unwanted touching is assault.

On the other hand, in private, intimate environments, that sort of touching can be welcome and fun. Context, as always, is key to understanding interactions with things you can wear.

Beyond unwanted touching, pranksters or “griefers” might think it is funny to reach over and mess with your digital interaction by touching the smartfabric device while you wear it. This could cause your data to become corrupted or trigger unwanted events in a system. (What if you were trying to book a calendar event, your friend reaches over and taps their fingers on your shirtsleeve, and now you have a thousand calendar events?)

We live in public, and smartfabrics might accidentally display personal information that we wouldn’t want others to see. What if a private text or email is displayed to my coworkers in a meeting because it is displayed on my shirt? (You might not want that nude selfie your significant other texts you to be displayed on your suit jacket when you are in a job interview.) What if I work in HR and my boss sends sensitive salary information that is displayed to an entire department I am presenting to? It could also be inappropriate for your dress shirt to display your photostream in church, or if your sombre outfit suddenly played the Benny Hill theme during a funeral. Understanding context and appropriateness of what to display and when, and how much control over who might see it users have is vital to understand and take into account.

Security and privacy is a huge issue with smartfabric devices. Data that is gathered from a user wearing smartfabrics is deeply personal. Any information that is passed to other devices or systems absolutely must be secure. That data should never be intercepted and stolen, it is very personal and could be misused and cause great harm to the user. If data transmitted from clothing or other devices could be intercepted by a 3rd party, that could be very embarrassing and potentially damaging if it is used against them. Also, if servers or cloud-based storage facilities are compromised and smartfabric generated user data is stolen, that could be catastrophic to the people whose data has been collected. The inevitable public backlash could be severe enough to destroy a company. Furthermore, data privacy laws could be broken and an organization could be faced with fines, lawsuits and the resulting bad publicity. Everyone loses if the data generated and used by these devices isn’t kept private and secure.

Private information should not be displayed publicly on my smartfabric device unless I want it to be displayed that way. I need to control what is shown, and when with speed and ease. Other people should not see my current status of what is going on with me and my body unless I want them to.

Smartfabric devices need to have their capabilities completely under the control of the wearer. When a feature isn’t appropriate in a particular context, or if something odd happens, the wearer need to be able to turn it off or mute it. Even active smartfabrics that change their form depending on outside triggers require user control to be able to turn it off.

Under controlled conditions (such as the development lab) you may never see irritating behavior, but in the real world strange things can happen. If your dress changes color depending on light and you are at a dance club, the lighting could cause the dress to rapidly change color. That requires a lot of energy if it happens over and over, so the power source could overheat and cause physical trauma (ie. burning) to the wearer. At best, it might wear your battery down prematurely.

Compatibility with other devices and services will also be difficult to address. What if my smartfabric jeans will only work with Android devices, and I only use Apple devices? What if the clothing that looks good on me and fits my budget is incompatible with my file hosting services I use and depend on? What happens if the smartfabric device manufacturer changes alliances, and my favorite suit company now only supports a platform I hate using?

Reliability is another issue that is difficult with clothing because we have to clean it constantly. How do we create hardware that can survive different weather, food and drink spills, sweat and other bodily fluids, and constant washing and drying? Clothing takes an absolute beating, and we subject it to extremes when we wear it, and especially when we clean it. This is an incredibly difficult environment for electronics to survive in, let alone work reliably in.

Two Possible Futures

The Scary Future

If we design smartfabric experiences poorly, we will distract people from their real world experiences, causing them to live diminished experiences when they wear these products. Instead of using technology to enhance their lives, we could burden them even more than our always connected experiences do already. Also, having more devices reading more and more sensitive and private information creates the potential to track people and make decisions about them based on their movements and biological data. This has incredibly serious, far-reaching implications. If people or organizations use this technology to reward or punish people due to the data that is collected, we could literally have a dystopian future on our hands.

If we aren’t careful, we might just create smartfabric products that are expensive, unreliable, irritating and in some cases, downright dangerous. That will be the kiss of death for the technology. If the solutions aren’t designed with empathy for real people, using them in the real world, not to mention our user’s needs, bodies and state of mind, they will quickly be relegated to the dustbin of history. The good that we could do with this technology would be lost because we did a terrible job with the user experience when we introduced our products to market.

The Awesome Future

Back when I wrote programs to help people on software teams be more productive, we used to joke that we were giving them super powers. They could now get visibility and control within systems that was formerly hidden from them, and use that information to make better decisions, or to diagnose and solve difficult problems. Similarly, even though we have many senses and powerful observation skills, there is a lot about ourselves and our environments that we can’t see. Sometimes this information can be incredibly important to get insight into.

I was delighted when Shannon Hoover (MakeFashion) suggested a similar superpower design theme with smartfabrics. Shannon goes beyond the concept of visibility and control, and he believes smartfabrics will eventually provide us with different superpowers by extending our senses, or replacing those that are injured or defective. Shannon says smartfabrics can help provide “X-Ray vision” by reading and presenting certain kinds of important data that are invisible to us. Just like a radio interprets radio waves and brings sound into a living room, smartfabrics have the potential to show us our current location and alert us where to move if we are travelling and get off track.

There are also applications to help provide us more strength and stability, and while we don’t all have access to a SciFi robotic exoskeleton (at least not yet), they are being developed for commercial and health related applications. Shannon goes further pointing out “spidey sense” activities to sense hidden danger, or important events. If the smartfabric is alerted to something that is important for you to know, it can get your attention to warn you immediately. Smartfabrics can use haptic feedback by interacting with your sense of touch in various ways to get your attention quickly.

Smartfabrics that sense danger and warn the wearer can be incredibly powerful. In particular, if our own senses are impaired due to illness, clothing that can warn us when our bodies are unable to can be life changing. Orpyx have created a vest that notifies people who can’t feel their extremities properly. Diabetic neuropathy sufferers can be warned of too much pressure in their feet by using sensors to vibrate against the wearer’s back to warn them. If your feet are getting injured, but you don’t feel pain, you can cause irreparable damage. Augmenting your body with another system to help prevent damage is an amazing feature to improve the life of people with illness and physical conditions. This also has enormous implications for safety gear and clothing for workers.

Once the wearer gets used to the alternative, haptic feedback, it feels as natural as the normal pain signals your body generates that you no longer feel from damaged areas. The technical term for this is “neuroplasticity”. Smartfabrics have the potential to use this as an “extra sense” to seamlessly interact with us in our environments. Shannon sees a future of products that can provide extra senses even for healthy users, to alert them or aid them as they perform tasks in the world so they are safer, happier and more productive.

Smartfabrics also have more whimsical applications that are also important. Imagine that you are at a holiday party in your new dress, shoes and accessories to match. You’re feeling good about yourself until you spot your nemesis from accounting. “That #$%#! She is wearing the same outfit! Disaster!

What do you do?

Smartfabrics to the rescue! You quickly dart out to the powder room, and with a quick, discrete gesture, you change the color of your dress. Crisis averted! This might seem silly compared to important medical or other applications, but this kind of technology would be incredibly useful for our quality of life.

Conclusion

Enhancing our bodies and our life activities with smartfabrics has the potential to enhance our senses, extend our physical capabilities and greatly inform our knowledge and insight. The choice for what future we want to bring to our users is in our hands. Do we want to enhance the lives of people who will use our products, or do we want to needlessly distract them away from what they should be experiencing?

Once smartfabric technology is reliable and inexpensive enough, we designers have some important work to do and not much time to do it in. Therefore, we need to choose what future we would like our customers to have even before we start designing.

Designing for Smart Fabrics: Wear It’s At – Part 2

In Part 1 of this series, we looked at defining smart fabrics. In Part 2, we will look at designing for them.

Deciding What to Design

Work with a Clothing Designer (someone who works with fabrics)

I can’t stress enough how important it is to work with someone who understands making clothing, and other handicrafts out of fabric and textiles. I spoke with Jen Kot, a professional engineer who makes her own clothing, knits and creates all kinds of interesting objects with textiles. As a technical person, she understands how the underlying technology works. As a crafty person, she deeply understands the application and costs of different textiles, the pros and cons of using different materials, what is easier or more difficult to work with, and what looks good.

Clothing is one of the most powerful tools we have to create and reinforce our image, or how we want the world to perceive us. One of Jen’s criticisms of much of the current wearables such as bracelets, watches and glasses are that they look “nerdy.” To a techie, we might not find this to be important. We may overlook the form for the features, and even find something awkward looking to be appealing. When you are competing in a world where fashion dictates what is available for us to wear in stores, we need to
understand how other people want to be perceived
.

When Jen and I brainstormed uses for smartfabrics, my solution ideas were much more functional. Her ideas were much more whimsical and fun. I kept thinking about how the technology could be applied and impact our lives, while she thought about what would look appealing as well as be engaging and fun.

Shannon Hoover, co-founder of MakeFashion, an organization that brings technologists and designers together to collaborate with wearable tech also reinforced this view. He also understands both the visual and technical worlds that are possible with smartfabrics.

Shannon says that many designers and developers are looking at wearables as a suite of tools (detect with sensor, compute data, send it to something else) but he also believes that isn’t very much fun. It seems very engineering-dominated, where we tend to focus on technology first, then apply it to a problem. Instead, Shannon feels we should also look at wearables from an aesthetic perspective (it looks interesting) and as a vehicle for
human expression. This is an artist and fashion-designer focused perspective.

Shannon goes even further, and says that clothing helps people tell the story about who they are – it is a narrative generator. It also gets people talking to you – it gets their attention and evokes emotions. Clothing is a great conversation starter. So what conversations do we want people to have about what we are wearing?

Using fabrics is complex, you need to understand how something looks on a person, how it feels on the skin, what colors are in fashion and how different cuts and shapes look on people. Fashion changes constantly. To make smartfabrics work, we will need both the technical view (here is how we make the technology work) and the fashion designer perspective (here is how we make the product look great and be appealing to wearers.) As a technology designer, talking to people who design clothing and furniture is exciting and helps generate new ideas. I understand the basics of what they are talking about, but their experience and perspective is completely different. When design materials use combinations of different technologies, our solution ideas are much better when we work together with other disciplines and share expertise and different perspectives.

Beyond Clothing

Making clothing is one way to use smartfabrics, but fabrics are used in a lot more things than clothing. For example, Nomex was used in heat shields for the space shuttle, Gore-Tex is used as a tissue replacement in medical procedures, and Kevlar is used to create high performance vehicle components. In fact, IoT developer and bbotx co-founder Geoff Kratz feels that smart fabrics have even more potential in products other than clothing. For example, he sees using smartfabrics in vehicle upholstery could provide alternatives for inputs and displays and other feedback mechanisms for safety purposes. Geoff also sees furniture as another good candidate. Smartfabrics could integrate with entertainment systems to provide an even more immersive experience. Chairs could sync up with other systems and provide you with reminders or safety information. Carpets could have safety lighting that is triggered by darkness or emergency situations. There is enormous potential for these sorts of ideas as well as interactive, connected art applications for homes, and public areas.

Quilter and chemical technologist (and reviewer of this article) Cindy Johnstone shares Geoff’s views. Since she quilts, she immediately thought of applications for blankets. Cindy says that portrait quilts or family quilts are very popular. She says the resolution of the images would be so much better if digital technology could be incorporated. An active smartfabric quilt that could tighten the batting to make it warmer in the winter and relax the fibres for summer use would be useful. People could use one blanket for different seasons, rather than having more than one blanket. Cindy also sees health care applications where adding in technology into blankets used by patients could provide more insight and control into patient care.

Corporate Innovation

As computing and wireless technology “disappears” into real world devices there is enormous potential to solve more interesting problems. We often look to organizations with well-funded R&D (research & development) programs to set the tone for the rest of us. There will be likely be useful, popular smartfabric products developed by some familiar leaders in the tech sector. The space is also ripe for disruption by some new up and coming organizations we haven’t heard of yet. Due to the combination of physical and virtual worlds, investment in these kinds of products will be more expensive than software alone.

One area that organizations are working on developing smartfabric and similar technology for is the health and wellness sector. Calgary-based Orpyx Technologies is a company that provides a wearable sensor platform for healthcare. In one of their products, they use embedded sensors in footwear to help people with diabetic neuropathy. Those with diabetic neuropathy have nerve damage and often don’t feel their limbs as well as other people do. Because they can’t feel when their feet hurt, they can injure them permanently. In severe cases this leads to amputation. Orpyx have developed a system to warn patients before this happens. A sensor-embedded insert worn inside a patient’s shoe gathers info from the sensors (pressure, etc) and transmits it to a smartwatch which then alerts them to potential problems.

Stephanie Zakala, Marketing and Inside Sales Manager at Orpyx says that they have been watching smartfabrics closely as a next step for some of their solutions. For example, rather than using embedded sensors within shoe inserts, a smartfabric sock would be a fantastic solution. So far though, there are technical limitations with the smartfabrics they have looked at. It is difficult to make socks with sensing capabilities that are comfortable, washable, and reliable over time. Stephanie says that clothing is particularly challenging because it creates hostile environments for electronics. Shoes and under garments are worn in conditions with pressure, high heat and humidity. Also, the high cost of many smartfabrics is currently prohibitive for many mass market consumer applications.

Other organizations are using sensors embedded in clothing to measure heart rate, temperature and other vital signs for healthcare, and athletics.

As smartfabric reliability improves and prices go down, many organizations will find them to be a great alternative technology for some of their current solutions. Beyond that, they will create new products and services by using smartfabrics to solve problems we were unable to address without this technology.

Innovation from Maker Communities

Great ideas don’t just come from companies, they can come from crowdsourcing as well. Craft communities are important crowdsourcing resources where people share interesting ideas for clothing and crafts. In these communities good ideas rise up to prominence because they work and are easy to replicate. Currently, there are knitting and quilting clubs, fashion collectives and maker fairs sprouting up all over, where people support each other socially, teach each other new skills, and most importantly, share patterns and design ideas so that others can make the same item.

As people try different patterns that others have created, they put their own unique spin on things, and improve on the original ideas. With such a large community, many ideas are shared and tested at large scale; far outstripping the resources of most companies R&D budgets and timelines might allow. Failure isn’t tied to profits and loss, so people can experiment without fear, and the best ideas tend to win out by becoming popular and emulated more frequently.

Homebrewing was a hugely vital part of early Personal Computer (PC) development, and this spirit of creativity and doing it yourself is evident virtually in craft communities. Adding technology to traditional materials is a natural step. In fact, while researching this piece, I found more people from craft communities that were interested in smartfabrics than technologists.

One community that reminds me of early PC homebrewing and software clubs is Ravelry. Ravelry is a community for people who knit and crochet, and it has a unique blend of features that allow people to share ideas and patterns. Local real-life knitting clubs have been started as a result of people from the same geographic location meeting virtually on Ravelry, then getting together and helping each other out. Sharing patterns and pictures of finished items is a huge part of the Ravelry experience, and popular patterns that help people create things that look good and work start to emerge.

Crowdsourced ideas from maker communities are often more fashion-conscious and whimsical than their corporate counterparts. Sometimes as technologists we forget that having a product that looks good and is fun is just as important to people as a life-saving device. It just depends on context. In fact, products that look good and are fun have a much larger market appeal. Maker communities are an area to watch because they not only filter the ideas for us, they remind us techies that the world can be a fun, colorful place and we need to incorporate those aspects into our designs.

These communities have access to a wealth of knowledge, and as digital designers, we can learn a tremendous amount from them. Once they have experimented with smartfabrics for a period of time, we can benefit from communities of people figuring out what works best for certain applications. These sorts of organizations are filled with people who like to experiment and create things for themselves and their friends. If you’re wondering where to start, Jen Kot says, make what is interesting and useful to you and then share it. The crowd can create at scale, so the good stuff will get copied and become popular.

Frame Your Design Thinking

Solve a Real Problem

When looking at technology first, and then trying to find useful applications of it, we can mistakenly create products that people don’t like. It’s important that technology solutions are actually useful and will be used by real people. Many wearables are not worn after a few months of use. In 2014, Endeavour Partners surveyed people who use wearables and found that one third of activity tracker users stopped using it after six months. Once people get a sense of the data that is measured and how that is reflected in their activities, they don’t seem to find a lot of value in the wearable information anymore.

It is vital to use technology that actually solves problems for people. Author and thinker Simon Sinek talks about “starting with why” we are doing something. In technology, we work a lot with the “what”. We have access to cutting edge technology, and we need to spend a lot of time learning how to master it and apply it. Many wearable and smartfabric demos seem to reflect this. People talk a lot about the technology and how it works, but they fail to make a compelling case for why it’s useful to me in my life and world right now. Very few people care about technical details, they want something that serves a purpose, looks good and fits their budget.

Think of buying a new pair of blue jeans as an example. When I shop, I look for something that solves my problem (I need clothing, specifically a new pair of jeans), that fits my personal style, that I look good wearing, and that I can afford. Invariably, I am drawn to a stylish visual design and a certain level of quality of materials and workmanship. Unfortunately, that means the jeans I would like to consider buying are expensive. Most importantly, the jeans have to fit my body and look and feel good while wearing them. So I start compromising to see if I can find something that fits my budget. If you are a smartfabric designer, how are you going to convince me to pay more money for something that has electronic capabilities in my jeans? It may just feel like an unnecessary extra. You have to convince me, the buyer, why I absolutely need this new technology in my jeans. Will they fit better? Will they look letter? Will they keep me warmer or drier or more comfortable? Will they provide data or notifications that are incredibly handy, or that I just can’t live without once I have them?

Whenever I design something new with complex technology, I strip the problem down to its essence, and I remove digital technology from the solution ideas at first. If I can use paper, pen, materials readily at hand and perhaps some physical services like mail or parcel delivery, what would I do? If you can fully understand the underlying problem you are solving and provide alternate ways of solving it with different technologies, it’s time to add in the digital technology to form a solution. It’s amazing how your perspective changes, and that pet feature you just loved in the technology doesn’t necessarily translate into an ideal product for the people you are designing for.

An ideal product should be so superior using smartfabrics to other, older technology, the customer will want it and will wonder how they got by without it in the past.

Paul Hanson (bbotx CEO) warns designers for wearables to avoid focusing on technology first, then looking for solutions in people’s lives. Instead, when we design wearables for people, we have to think about the person wearing the device first, what they are doing in their lives and how the technology that the device provides is useful for that person. However, it can’t stop there. Beyond the device itself, the generated data and activities recorded or performed by the wearable are much more useful when you take an entire system (such as your interactions with other people) into account. Gathering a lot of data with a smartfabric wearable and displaying that data on a smartphone has limited usefulness.

What does it mean? What should the wearer do?

With passive wearables, which are usually used to gather data, there is limited value in providing activity data only to the end user. There is infinitely more value if that data can be shared with people who can interpret the data, and have special expertise to help apply that to help you improve your life. In healthcare for example, clothing that monitors heart rate is incredibly useful if care givers or specialists have access to the data to help put context around it and point you towards behaviors that will benefit you. This requires a complex, secure computing system to support not only the wearable and the user, but everyone else who needs to be involved.

Active wearables need to interact with a system too – the immediate real world around us. Imagine a winter jacket that changes form depending on temperature so you are always at optimal comfort, or a shirt that changes color depending on lighting. The data the wearable interprets around them can trigger change in the form or attributes to enhance the experience of the wearer. Ideally, the user should be able to control these changes themselves if they want to override them.

Interfaces and Inputs

In my last article on wearables, I suggested that the real world is your primary user interface. With smartfabrics that can be used as clothing, user interfaces can also be on people’s bodies. Not only do you need to understand where the user is, what they are doing and what the environmental conditions are, you also have to understand where on the user’s body the user interfaces and inputs will take place.

Finally, you have to understand the inputs and outputs and displays themselves. This is incredibly challenging.

On a PC, we are used to input methods (keyboards, pointers, stylus, microphones, fingers, etc.) and output on a screen, from speakers etc. The end user tends to use the PC in more ideal conditions, and we don’t think too much about what else is going on around them. Mobile devices complicate I/O matters, because now we have to think about limited actions, and what else is going on in their world as they use our programs on the move.

Wearables such as smartwatches and activity trackers complicate this further, since they can overly distract from our real world activities, and since we are wearing them on our wrists or clipped on to clothing, we can’t get away from them if they needlessly over stimulate us with notifications and alerts. With smartfabrics used in clothing or furniture, the devices are right up against our skin and have much more opportunity to distract and annoy us. Can you imagine how terrible an experience could be if your clothing was vibrating or lighting up and you couldn’t stop it? It could be embarrassing, irritating, and could even cause injury to the wearer.

Deciding where to provide inputs and outputs on smartfabric is incredibly important for a design. With furniture or objects we interact with, it can be more straight forward, but would still require a lot of user testing with different users to get right. For clothing, it gets much more complicated. What are sensitive areas of the body we would want to avoid for inputs? How about appropriate areas for screens or lights or other outputs? If outputs or inputs they draw attention to private parts of the body, that could be disastrous in public, or just the right thing in private. We do not want to expose our customers to unwanted attention or touching, and they need to be in control of their own bodies and what technology can do to enhance them.

Smartfabric designers need to think of inputs and outputs for smartfabrics:

  1. What is around users in the real world and what activities will be enhanced by the technology
  2. The human body – where and what is useful with regards to inputs and outputs what is and feasible to put on or around our bodies and appropriate given the context of use
  3. The inputs and interface designs themselves

Design for Simple Interactions

On mobile devices, we have learned that we can distract people needlessly and take away from their real-life experiences rather than enhance them. If an app is annoying, people just delete it and move on. As designers, we must understand the context of use, such as the environment around users, and what they want to do at a particular time with the technology. We also know that people have less time and space to interact with mobile devices than they do with larger screens, so we have to develop for quick, economic interactions rather than a long workflow. For example, if I am walking outside with my smartphone, it is much harder to interact with than when I am sitting comfortably at a desk typing on my PC. If I am in a hurry, or I am in bad weather, it is even more difficult.

Now think of clothing you are wearing that is designed with smartfabrics. They are even more difficult to interact with than a small smartphone. What is going on around us and our limited ability to see and interact as we move around are amplified with smartfabrics. Imagine how irritating it would be to not be able to control or turn off notifications on your clothing, or how dangerous it might be if the smartfabric distracts you when you are walking, driving or riding a bicycle. The simple interactions mantra that mobile designers repeat over and over is that much more important to take into account with smartfabrics.

MakeFashion co-founder and UX designer Chelsea Klukas says: “…the most successful mobile products have created experiences that quickly allow customers to continue a task after interruption. With wearables these interactions will become even briefer, and successful experiences will need to be quick with minimal interruption to the user. Interfaces will need to be designed to rely on simple one-tap inputs and voice commands that can be achieved instantly.”

With wearables, the real world should be your primary user interface because that is what holds the most attention for the wearer, not the technology. Wearable technology should be designed to work within that context to complement real-life experiences. Chelsea says: “As wearables gain widespread adoption, we are going to have to be increasingly sensitive to the amount of interruptions and distractions they cause. When used correctly, wearables can be incredibly useful in providing information, wayfinding, or accessibility. When used incorrectly, they can become distracting and provide interruptions to user’s tasks and routines.”

Wayfinding came up a lot when I talked to people about possible applications of smartfabrics. Shannon Hoover suggested that smartfabric clothing that could sync with a map service would be hugely beneficial for tourists and travellers. If clothing provided tactile indications (such as through the use of a vibration motor) and subtle visuals, finding your way in an unfamiliar place could be much more enjoyable than having your face in a smartphone or an old fashioned map. You could focus on your surroundings, and have a richer experience, without worrying about going off your planned route. The clothing would remind and guide you. This could also be safer, you wouldn’t be a target as an obvious tourist to pickpockets or scammers.

Others described ideas using smartfabrics for people operating a vehicle. This technology would not be as visually distracting as looking at a smartphone or GPS map. Motorcyclists and bicycle commuters in particular found this a welcome change. Instead of relying on a hand held or mounted device that would distract their visual attention away from where the vehicle was heading, they could get tactile indications of where to go.

Smartfabrics could provide the ultimate handy interface for quick reference, reminders and interactions on the go, or they could interrupt needlessly and distract away from our real world experiences. Furthermore, since the human body is a secondary user interface, there is really very little difference between touching fabric on your body and touching bare skin. Imagine rubbing your thigh in one spot 100 times a day. How do you think your leg would feel in an hour, in a day, or after a week?

Simplicity is not only necessary for a good user experience, it could be necessary for our health, well being, and our relationships.

In Part 3 we will look at things that could go wrong with this technology, and offer up two possible futures for products using smartfabric tech.

Designing for Smart Fabrics: Wear It’s At – Part 1

Lately, the term “wearables” appears more and more in our conversations. Usually we are describing a smart watch that extends our mobile experience, or a bracelet that tracks physical activity. Sure, those are things we wear, but what about something with computing power that we actually put on as clothing? Now that is something that is really a wearable. This next wave of wearable moves technology beyond accessories to clothing we wear, furniture we use, vehicles we are transported in and art that we enjoy.

This is made possible through smartfabrics. Smartfabrics are textiles with embedded electronics that bring computing power even further from our devices into everyday items. This technology poses new challenges for designers. Not only is the form factor very different from screen devices, it is right up against the user’s skin.

This is an interesting topic for me. While I have done design work with smartwatches, wearable integration and for Internet of Things (IoT) devices, I haven’t worked with smartfabrics yet. So I reached out to people in the community who have more insight than I do, and asked for their thoughts to share on the future of this technology. This is more of a forward-looking piece than my usual experience-reports, so I will likely get some of it wrong. However, a lot of you have been asking me to weigh on on this topic. Furthermore, the low impact, high value principles behind designing for this technology are important to take into account as we move forward. We might have a limited window of opportunity to get it right.

In my last article on wearables Designing For Smartwatches And Wearables To Enhance Real-Life Experience, I wrote about designing experiences that integrate smartwatches and activity trackers. I mentioned that we have two futures for technology: in one, we are distracted away from our real-world experiences, increasingly focused on technology and missing out on what is going on around us; in the other, technology enhances our life experiences by providing a needed boost at just the right time. Understanding good distractions as well as unwelcome distractions is vital to consider when you are designing for something that you will have right up against your skin for hours at a time on a daily basis. With smartfabrics, we have even more potential to cause harm by distracting people from their lives, or to bring even more good by using powerful technology to enhance our real-life experiences.

As I spoke with people who design with smartfabrics and similar technology, a common theme emerged: smartfabrics aren’t quite there yet for mass market applications. There are some niche players leading the way, but nothing has captured significant mind share. That’s because it’s difficult to bring computing and electronics, power sources, sensors and wireless connectivity to fabrics without making them bulky, impractical, and expensive. However, a lot of great organizations with brilliant people are working hard to create reliable, cost-effective smartfabric technology, so the day will arrive soon. When it does, those of us who are technology designers will be designing digital experiences that are completely different from the screen experiences we are accustomed to. It’s important to understand that we are designing a digital experience that supplements a user’s real-world experience.

Electronics

One way to think about smartfabrics is that they are Internet of Things (IoT) devices. In his talk Magical UX and the Internet of Things , mobile UX expert Josh Clark defined IoT devices as “Sensors + Smarts + Connectivity”. A “thing” is anything at all that we can put technology into. “Sensors” are what make mobile devices and wearables truly special, they can sense movement, direction, and in some cases even biometric data.

“Smarts” refers to computing power and electronics that makes sense of data, and supports inputs and outputs into the system.

“Connectivity” allows us to get information from the thing onto smartphones
and other devices. It is one thing to have a wearable that measures or allows for inputs and outputs, but if it can only work by itself and not communicate with other computers, it has limited value.

Sensors, smarts and connectivity depend on power sources to operate, which means they need batteries to make them work.

Smartfabrics are textiles with IoT-style technology woven into them. Some technologies added to textiles are sensors, wireless, batteries, location services (such as geo-positioning tech), transducers, bio monitors, lighting and displays. New kinds of fabrics blur lines further with electronics in the development of conductive thread for inputs, and stretchy displays, circuit boards and wiring embedded right into the fibers or printed on the fabric. In some cases you can barely tell the difference between smart fabrics and traditional textiles.

IoT devices provide visibility and control into just about anything we can stuff technology in. Paul Hanson, CEO of IoT technology company bbotx points out that they “help create enhanced situational awareness.” In other words, IoT devices can help us extend our own capabilities by providing visibility and control into our environments, our interactions with other people and systems, and within ourselves. For example, health monitoring with wearable IoT devices can provide constant flows of data so the wearer can make better health decisions. With IoT technology, this insight is also available to health experts. What was once a sporadic activity – that required an appointment, specialized equipment and expertise – can now be an ongoing, continuous activity. These systems provide a degree of insight into a patient’s day to day conditions that was impossible before. Patients get visibility into their current condition at any time, and experts can closely monitor changes and recommend treatment options.

Doug Hagedorn, CEO of Tactalis describes two different kinds of smartfabrics: passive and active. Passive smartfabrics are designed towards monitoring and gathering information to for use within a system. Active smartfabrics react immediately to stimulus in the environment and may change physical aspects such color, shape or their digital behavior. Passive smartfabrics have enormous potential in areas such as health and fitness, while active smartfabrics could reduce the need for multiple articles of clothing that have one particular purpose and design.

Fabrics & Materials

If you are a digital designer who like me who in virtual worlds all the time, integrating software with real world physical objects can be a challenge.

Textiles are commonplace enough to appear simple, but they are subtly complex. From ancient times, we have used animal and plant-based materials to clothe ourselves for protection and warmth. Eventually, we brought in metals and other minerals as materials. (The most obvious example of this is medieval armor such as chainmail.)

As technology advanced further, we moved beyond natural resources and started making synthetic fabrics. Today, textiles are sophisticated combinations natural, synthetic, mineral and other materials. We take them for granted because they are all around us, and the complexity is hidden from us.

The choice of material when designing clothing or other textile goods brings with it different strengths and weaknesses for warmth or cooling, comfort or sturdiness, and care when dirty.

To get more out of a particular fabric, we combine different materials to make it even more useful for a particular purpose. Some interesting examples of technology fused with technology are:

  • Kevlar used in fabrics for protective wear
  • Gore-Tex Water repellant technology to keep us warm and dry
  • Nomex provides flame resistance
  • Spandex provides support for athletic wear and underwear
  • Conductive thread in our mittens and gloves allows us to use our touchscreens in the cold.

When you weave these powerful fibers into fabric for use in clothing, it allows the wearer to do things that were previously difficult or impossible. In most cases, you wouldn’t even know that complex technology is in your clothing unless you looked at the label. Similarly, as electronics become smaller, they become a part of the purpose of the clothing. They fade into the fabric so that we don’t even notice them. Smartfabrics have the potential to allow us to do much more with clothing and other objects than we can with traditional fabrics. The key as a designer is to know exactly what kind of smart fabric you require to solve a problem for your users.
