DVRC-iTV: Download Variable Remote Control for Interactive TV

TV is one of the most important home appliances and the remote controller is a crucial TV input device. TV remote controllers have always been designed with TV compatibility in mind, with little concern for TV programs or ease of use. This is a serious limitation to the development of TV services, such as iTV (interactive TV). A system framework is proposed in this study in which external displays (TV or projector) are utilized effectively and allow users to execute “variable remote control” with their handheld devices absent any locating process. Users can operate iTV services more effectively and enjoy enhanced freedom of mobility; moreover, the variable design increases interactivity with TV programs. The experimental results indicate that the proposed framework is applicable to iTV services and that users can operate the framework in any “visible” environment, without regard to different categories of display.
