3

Last year’s talk• Slides available at http://bitly.com/csun2016

• Examples of recent wearable assistive devices• Wearables for sensory substitution, rehabilitation,

communication support, emotional and behavioral support

• Design considerations for assistive wearables

4

In this talk• Update on recent trends in wearable assistive

technology• 2 studies on the social implications of assistive

wearables• Projects from our research lab• Next steps, challenges, and opportunities

5

Why is this an exciting time?• Wearables are a growing market• Assistive-ish devices• Wearables as fashion items

6

The wearables market• Approximately 40

million devices sold in 2016 (up from 32 million in 2015)

• New form factors: hearables, smart glasses

8

Wearables as fashion items

Advances in textile-based computing• Textile based computing components• Flexible circuit boards, conductive thread, etc• Modular tools for creating wearable devices

10

Textile-based computing

Gilliland et al., The Textile Interface Swatchbook LilyPad Arduino

13

The big idea• The growing availability of wearable technology

can affect perceptions of technology and the user

14

Understanding perceptions of wearable technology in public• Collected data from 1200 web

users about perceptions of a wearable computing user

• Adjusted physical appearance of user and description of video (disability, assistive use)

• Is the user: cool, awkward, nerdy, distracting

• Paper

15

Findings• In general, participants reported that they felt more

positively about examples when the individual was identified as having a disability

• More specificity about the use resulted in more positive reactions

• “I would be less likely to form a negative opinion of a disabled person wearing such a device, because I would likely believe that it was helpful or necessary for them. A non-disabled person using such a device in public is more likely to seem obnoxious.”

16

Takeaways• Explaining that a

device is assistive (and what it is useful for) improves perception– Similar to service dog

jacket• But, this threatens

privacy• Can we provide control

over disclosure?

17

Understanding customization of on-body assistive devices• Studied an online

community with over 4,000 users dedicated to decorating hearing aids

• Analyzed posts, questions, methods used

• Link to paper

18

Findings• Many people decorated their

devices using stickers, colored tape, etc.

• Shared techniques online• Many examples involved

parents designing for their kids• Decorations were contextual• Decoration seemed to differ by

gender

19

20

Follow-up interviews• “…it means you have a certain power over something which

is attached to you that you wish rather wasn't attached to you.”

• “Where before it would be unwanted attention… it’s now compliments.”

• “By drawing attention to them you're signaling to other people that it's okay to talk about that. As it's an indicator for something to ask about it.”

21

Takeaways• Decoration reveals a

strong desire to customize devices

• Suggests design trends (coordination, using favorite characters)

• Challenges to supporting DIY modification

Example Wearable Projects from Our Lab

Flutter dress

• Spatial Awareness of Sounds for Individuals with Hearing Impairments

• Microphones and vibration motors embedded in garment detect and relay sound direction

• Leveraging fashion to integrate hardware

• Profita et al., Flutter: An exploration of an assistive garment using distributed sensing, computation and actuation

LightWear – wearable light therapyHalley Profita, Roseway, Czerwinski

• Wearable light therapy for seasonal affective disorder

• Different form factors (hat, glasses)• Study participants willing to use in both public and

private if appropriately designed and controllable

26

Chairable Technology• Power wheelchairs can be

cumbersome

• How can we make using a power wheelchair an asset?

• Use wheelchair as a computing platform

• Papers: 1, 2

Supporting diverse gestures

Wearable AAC devices• Textile-based wearable AAC device

for sports therapy (Halley Profita)• Fabric-based user interface

– Flexible– Can be worn during sports– Very simple UI– Not dynamic– Family collaboration

31

Challenges and opportunities• Technical

– Ensure assistive features are integrated into mainstream wearable platforms

– Allow customization of on-body placement and input/output– Support remote control from smartphone or PC

• Social– Ensure policies allow (responsible) use of wearables in public

spaces– Support customization and concealment of devices

32

Conclusion• Wearables are not one-size-fits-all solution• Technology is enabling new kinds of support via

wearable devices• Challenges to ensure appropriate features

included in emerging wearables platforms• Assistive wearables: “separate but equal” vs.

universal design
