A personal digital assistant as an advanced remote control for audio/video equipment

This paper describes a personal digital assistant that is used as a catalogue and advanced remote control to browse, select and play music in a compact disc jukebox. The application has been developed as a research prototype to identify advantages and disadvantages of different interaction styles for accessing large amounts of content. The basic concept provides easy access to a personal music catalogue, anywhere and anytime. It also allows you to control the CD jukebox. It employs a multimodal interaction style which combines voice control, touch input, visual output with animations and functional sounds. This helps to overcome the typical problem of accessing large information resources through small displays. In addition, redundancy in both input and output techniques offers people alternative ways of interacting with the content. The concept will be described and demonstrated, and relevant user studies will be explained.
