To realize a symbiotic relationship between humans and computers, it is crucial to estimate the external and internal state of the human by observation. One promising approach is to acquire the same visual information as the human ac-quires. In this paper, we introduce our wearable vision sen-sor, which is equipped with a pair of active stereo cameras and a gaze-direction detector. From the visual information obtained by the wearable vision sensor, we present three ba-sic three functionalities: a 3D gaze point detection and im-age retrieval, a 3D digitization of a hand-held object, and the measurement of a walking trajectory. 1.
