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:

Food Management System for the Visually Impaired." January,
