ABSTRACT
We are developing a videoconferencing system designed specifically to cater to the needs of the elderly and their distant friends and family. Focus group research has led to the incorporation of several key features that enhance the usability of the system. Audio and video transmission quality are optimized by separation, using the proven and familiar capability of analog phone for voice and the slightly less reliable, but faster data transmission of broadband Internet for video. A simple and intuitive user interface was designed based on the familiar steps of an actual household visit. The graphical interface is presented on the user's conventional television receiver and controlled by a simple seven-button remote control with integrated wireless microphone, which provides high quality audio pickup. The system can be remotely activated by a wearable wireless alarm button or by visitors with passkey privileges. A functional prototype has been developed and is currently undergoing field-testing. Preliminary response has been very encouraging. Future plans include extended focus group research, collaboration to integrate improved video transmission schemes, and in-home testing by seniors to gauge long-term user response.
