Site Controller participants see and hear the presenter live, delivering content or issuing test questions on a TV monitor. Using the Response Keypad, participants interact easily with the presenter and each other. By touching the Call key, for example, a participant "raises a hand." At the same time, the presenter sees the calling participant's name, location, and picture. Speaking naturally, the calling participant converses with the instructor. Every other participant hears both the calling participant's and the presenter's dialogue – just like in a conventional class. Remote participants also use the keypad to respond to questions issued by the presenter.
The Response Keypad is an easy-to-use, personal interface which allows users at all skill levels to be active participants in the classroom. The One Touch Classroom solution is 100% reliable, does not carry the extensive support overhead of a PC, and incorporates all the interactivity found in a live classroom – extending the reach of communications and training to remote locations.
Interactive Audio, VoIP
One Touch Presentation Server has an Audio Server module that has the capability of managing and delivering three way interactive audio using VoIP (True Speech, Speex audio CODEC). The instructor has control over all audio calls during a live session. Instructors can select any student at any time during a session for a call from the participant database on the One Touch Presentation Server. Instructors can call two students simultaneously for a three way conference. All of the conversation of the call is rebroadcasted to all remote site classrooms in real time.
For students, each One Touch keypad has a Call function key to request a call if he or she has a question. The One Touch Presentation Server User Interface has a call window that displays who is calling and from where they are calling, giving the instructor control to open or discard any call requests.
The One Touch Site Controller unit has a sophisticated audio suppression mechanism with delay control to avoid audio echo at each remote classroom in the satellite network.
