The Smart Bracelet
is a lightweight wearable device intended to aid the visually
impaired in identifying food
items that are tagged with radio frequency identification
(RFID) tags. The system prototype was created as part of a semester long
HCI group project. The project involved task analysis,
identification of domain space,
research into the feasilibity and advancement of RFID technology, paper
prototyping,
and physical prototyping with a "Wizard of Oz" program that simulated
actual response of the Bracelet to an RFID tag. Finally, the system prototype
was tested with visually impaired users at the Center for the Visually
Impaired
in Atlanta.
The Bracelet contains an RFID sensor
which detects signals from RFID tags in close range. The
system accesses data about that tag and audibly speaks
information to the user. Users can choose between basic
information (name of product only) or expanded information
(name of product, nutritional information, and expiration
date). Users also have the option of recording data onto
their own customizable RFID tags.
A paper has been submitted to CHI 2004 describing the system
and its creation:

Impaired." January, 2004.
