Speech enhanced remote control for media terminal

A media terminal box combines digital television and services on the World Wide Web. This device will be available in many homes and the interaction with it occurs via a remote control and a visual presentation. The problem is the navigation difficulties among the huge number of television channels. The aim of this study is to investigate whether spoken commands could solve the navigation problem. In this study two input techniques were tested: remote control and speech input. The results showed that speech input was more effective as steps to complete tasks were less and shortcuts were used more often in the speech condition. However, the subjective data showed that the subjects were more satisfied with the remote control input. In conclusion, we recommend multimodal interaction where of speech input to complement the remote control unit.
