Abstract: Context sensitivity is an important application of wearable computers. This paper describes research on using the Twiddler one-handed keyboard for sensing motion-associated context. Two possible methods for detecting walking are described, and other types of movement context that it might be possible to sense are discussed. Results of early experiments with a preliminary Twiddler driver modification are discussed.
