Evaluation of a Prototype Remote Control for Digital Broadcasting Receivers by using Semantic Differential Method

摘要

Digital broadcasting makes it possible for viewers to enjoy a variety of new services on many channels. However, the receivers require complex operations in some cases. A survey conducted in England, which started digital broadcasting before Japan did, shows that the difficulty of operating a digital television or interactive television was almost equal to that of a PC. Since television is a media for everyone, from children to the elderly, an easy-to-use user interface is needed so that all the users can make full use of the convenient services of digital broadcasting.
