A really wearable input device " FingeRing " is developed for coming wearable PDAs. By attaching ring shaped sensors on each finger, many commands or characters can be input by fingertip typing action. " FingeRing " can be used on any typing surface such as a knee or desk, so quick operation is realized in any situation while standing or walking. To improve(More)
"Active Click" is a new interface mechanism for addling tactile feedback to touch panels. A small actuator is attached to a body of PDA or the backside of a touch panel. The tactile feedback, created by driving the actuator with a short pulse, is perceived by the grasping hand or tapping finger-tip when the panel is tapped. Active Click is effective in(More)
ABSTRUCT This paper presents a human pointing action recognizing system called Finger-Pointer. This system recognizes pointing actions and simple hand forms in real-time by an image sequence processing of stereoscopic TV cameras. The operator does not need to wear any special devices such as Data-Glove. Fast image processing algorithms employed in this(More)
A headphone-type gaze detector for a full-time wearable interface is proposed. It uses a Kalman filter to analyze multiple channels of EOG signals measured at the locations of headphone cushions to estimate gaze direction. Evaluations show that the average estimation error is 4.4® (horizontal) and 8.3® (vertical), and that the drift is suppressed(More)
A new interface concept for mobile computing, the 'l+dl-time Wearable Interface " , is proposed. By wearing tiny interface devices similar to watches or glasses all the time, the user can operate PDAs at any time desired. As the first study of such an interface, we propose the finger ring style chord keyboard named " Fingering ". FingeRing can be used with(More)
Many gesture interfaces such as "Put-That-There" require operators to wear special devices such as "Data-Glove" to make the system recognize hand gestures. However, wearing such devices prevents the realization of a natural interface. We have developed the "Finger-Pointer" experimental system, which can recognize pointing actions and simple hand forms in(More)
