A Haptic Warning Wearable
To Support Deaf People Communication
> How to call someone and start a conversation
when there is no visual contact, no physical
contact and no possibility of sound?
> This might sound very impossible or rare.
But it is quite common, specially when:
- people have hearing and speaking disabilities,
- people are riding bikes,
- people are in a noisy crowd,
> How hearing impaired are warned about:
doorbells, telephones, fire alarms?
By visual signs. But if they are not looking at it?
Graham Bell would give balloons to deaf children
so they could be aware of horse carriages
while playing in the streets.
They just felt its VIBRATION.

How to support people who wish to communicate
when they don`t have physical and visual contact and
cannot count on sound and speech?
- Communication channel for haptic warnings
through a wearable device.
- System allow users to draw other user’s attention through
haptic sensation without using voice/ vision/ physical contact.
- Group notification
(when someone gets too far away)
- How can this device change daily routine?
- peripheral position at user’s attention
- to be used in daily routine: accessory
- easy to carry
- easy handling (urgent tasks)
- strong vibration in a sensitive area
- automatic feedback
- aesthetics: computer or clothing?
- exploratory case study
- “I want to talk to you”
- one press the button, the other feels vibrating
while one receives feedback
- public: deaf people
- how does it look like?
- pair of belts
- arduino: open source platform for hardware prototyping
- lilypad: wearable components for arduino, sensors and actuators
- xbee: wireless transmitter/receiver
- exploratory case study
> 1st: questionnarie and interview
- 5 talking volunteers
- print manual
> 2nd: focus group
- 10 deaf volunteers
- translator needed
> 5 people:
- 3 young / 2 adults
- 3 women / 2 men
- 4 hearing / 1 disabled
- wear the belt, make it work, walk around in other rooms
or out of the building and return when he/she felt it vibrating
- questionnaire and interview
> All leanerd quickly and considered easy to dress and to feel vibrating,
comfortable, aesthetically neutral, but difficult to turn on (lilypad switch)
> 3 of 5 interested in different levels of vibration, concerned about electrick
shocks and not bothered by eletronic components appearance
> easy to call and to feel the call, feedback vibration really useful
- walkie talkie concept: own code for communicating
- hearing impaired girl wanted to buy regardless of price
> 10 people:
- from the same pastoral group
- 10 deaf adults - 6 women / 4 men
- 3 minutes explanation
- try the system freely, with group interaction
- group interview with translator
- all enjoyed the idea
- all women tried, all men didn’t
- good and beautiful (but hot under clothing)
- curiosity about maximum distance
- vibration might bot be strong enough
- places to use: home, work and parties
- question about how much it costs
- suggested scenarios
- proposition well accepted, indicating wearable computing and haptic
communication can improve deaf people’s lives
- design guidelines fit well
- need of better hardware design
“perfect” in LIBRAS
- long lasting evaluation
- multiple users, group, broadcast
- try communication codes
- connect to environment devices
such as doorbell
