Abstract
An apparatus for acquiring human finger manipulation data includes at least one finger motion detector consisting of a force sensor to be fitted on a human fingertip, at least three links and at least four angle detectors; and a base supporting the finger motion detector. The base can be attached to an external mount or a human hand. The force sensor is connected to the base through a link mechanism constituted by the links, and the angle detectors are attached at pivots between the links and optionally at a pivot between the link mechanism and the base. Three-dimensional motion of the finger is determined by measuring data of the angle detectors of the link mechanism, and fingertip contact force is measured by the force sensor. Up to five finger motion detectors, one for the thumb and each finger, can be supported on the base.
