SLEEP DISORDERS--A PRIMARY CARE APPROACH ON THE WEB

Not Available The basic requirement of the Phase I research is to determine the requirements for a Virtual Internet-based-Sign Language Teaching Assistant (VISTA). A VISTA system will consist of an Instructor instrumentation Station (I2S) , and an unlimited number of Student Multimedia PCs (SMPC). The I2S will utilize a state-of-the-art optical tracking system to track finger, hand, arm, and facial movements to provide real-time position information. The position information will be translated into the industry standard Virtual Reality Modeling Language (VRML). Audio from a microphone or other source will be digitized and compressed using a standard streaming audio format. Both the VRML and audio data will be broadcast via the Internet to student PCs. The I2S will multiplex incoming audio from microphones on the student PCs for replay. The SMPC will consist of a standard Pentium_ processor running Microsoft_ Windows_ with Internet service and the VISTA student software. A virtual instructor performing the motions of the trainer will be shown with instructional audio while student audio is sent concurrently to the I2S.
