A joint localizer for finger length measurements

Abstract

Hands play a very important role in human daily activities. Hand robotic exoskeletons for rehabilitation have been and continuously are developed by many research institutions. Generally, the information on finger length is required while using such device and assessing part of hand function. In this paper, we propose a hand joint localizer and a related hand model to measure the individual finger length by marking every key joint location on the plane. One can further translate these points into the line segments connecting them, and all these data will be stored into the computer database afterwards. The hereby developed device actually provides a simple and intuitive solution to finger length acquisition.
