Research output: Chapter in Book/Report/Conference proceedingChapter


The purpose of this study was to develop a finger display device that has a four-degree-of-freedom (4DOF) length. This device was designed for rehabilitation and cognitive experimentation. The device can change the finger span between the thumb and four fingers, and the distance between digits is controlled by four motors. The positions of each unit, including the motor, are self-adjusted. Adjustments are made after recording the motion of the individual's hand and analyzing fingertip movement. Each finger is controlled independently, and rehabilitation is performed on each individual finger. The device can be used for not only rehabilitation but also basic tactile studies. In particular, this device provides a valid method to measure length.
