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)
An eartip made of conductive rubber that also realizes bio-potential electrodes is proposed for a daily-use earphone-based eye gesture input interface. Several prototypes, each with three electrodes to capture Electrooculogram (EOG), are implemented on earphones and examined. Experiments with one subject over a 10 day period reveal that all prototypes(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)
