Abstract

Force feedback displays to represent virtual objects with non-grounding and no reaction base on the human body are convenient and effective for mobile uses. Especially, these sensations are expected to be applied to ubiquitous/mobile/wearable interfaces for technical training, rehabilitation and telemanipulation in the variety fields of medical care, healthcare, and welfare. In this paper, fingertip type non-grounding force feedback display has been developed to represent the feeling of presence and shape of virtual objects continuously by downsizing to be mounted to fingertip and position feedback controlling. This display represents haptic sensation of vibration, torque, and force feedback in any arbitrary direction by controlling rotor acceleration and phase difference of eccentrically weighted rotators.
