YOUTUBE DEMO

► DeafTechNews’s hands-on at DeafExpo

INTRODUCTION

► Ken Love

►5th-year Computer Engineering Technology student

► Vision: A Bluetooth notification device for the deaf and

hard-of-hearing people

►Flashes and vibrates when someone calls a deaf/HH person’s

smartphone

► Owners: NTID Center on Access Technology and ZVRS

GENERAL & DETAILED DESCRIPTION

► A keychain-sized device with a MSP430 microcontroller with

WT12 Bluetooth 2.1 module

► Powered by a lithium-polymer battery with a capacity of

130 mAh

► Equipped with a super-bright LED and small vibrating motor

► Uses Serial Port Profile to communicate with ZVRS’s

interpreting relay service application on smartphones.

► Options for both, flashing, vibrating only

PLANS FOR NEW GENERATION

► Expand Bluetooth support to iOS devices

►Hands-Free Profile

►iAP

► Ability to download the firmware to MSP430 via USB

► Add a switch for system power controlling

► Add a RGB-LED for system notifications

RETROSPECTIVE

► Original product: Notification device connects with Android

and Apple smartphones via Bluetooth and flashes/vibrates

to get the user’s attention when ringing

► Final product should be same as the original, but with new

and improved features

►Downloading via USB

►Switch for turning the device on/off

► Following the project management methodologies (currently

in performing and testing)

RETROSPECTIVE (CONT’D)

► Biggest roadblock: Apple

►Bluetooth profile for connecting the device with iOS devices

(iPhone, iPad, etc)

►Authentication chip/co-processor

► Really like working on the project

►Researching and testing for new components

►Building the device and seeing it working

RETROSPECTIVE (CONT’D)

► Learned much during working on the project

►How Bluetooth and WT12 module work

►C programming language

►Populating and soldering the SMT/SMD components

► Advice for future ESDIII students

►Research and ask tech support or forums (TI’s E2E forums,

Bluegiga’s tech support, etc)

►Get the breakout devices if there are several (Easier for

experimenting and testing)
