The recognition of a user's internal states via physiological sensors is sometimes seen as a matter of detecting the direct physiological correlates of the internal states. This type of detection can be problematic when a user is moving around, as is often the case with today's mobile systems. We present a study which illustrates that detection of internal states is sometimes actually easier when the subject is moving: The affective state may be associated with overt behavior that results in detectable changes in the physiological variables.
