EZRA II Environment Control System
The EZRA II System is an environment control interface created to allow quadriplegic and other disabled persons the freedom to control their living area. The system currently includes a Bluetooth connected hospital bed controller, a speech synthesizer for those with limited speaking abilities, and an interface to control "X-10 home automation" enabled lamps and appliances. Future plans for the system include integration with various multimedia devices, gaming consoles, and speaker phones. The user interface for the EZRA II system is an HDMI connected monitor and the user input consists of several discrete "sip-puff" pressure switches.
