Wearable Microphone Array as User Interface

We are at present enabled with machine-empowered technologies. The future is certainly looking towards human-empowered technologies, which should enable mobile user with natural wearable devices along with natural-like user interfaces. This paper presents proof of concept of wearable microphone array system that could be embedded in textiles for hands-free, obtrusion-free and hassle-free operation interface with body-worn computer, which is replaced with a speech recognition engine with a PC for testing. One mode of microphone array is for useronly speech interface with the computer and another mode is to collect others voice and steer it by voice control to get maximum sensitivity. The details of microphone array systems are beyond the scope this short paper. The concepts and the preliminary promising results are presented here to register our thoughts with `wearable computers/ user interface' community
