  2. 2. 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
  3. 3. 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
  4. 4. 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
