ELECTRONIC INTERFACE AND SIGNAL CONDITIONING CIRCUITRY FOR DATA GLOVE SYSTEMS USEFUL AS 3D HMI TOOLS FOR DISABLED PERSONS

A simple PC screen can be considered as an interface of a virtual environment where an user can move objects and interact with them. The interaction tools can be simply a virtual mouse or a keyboard. But it is evident how these tools cannot provide an immersive experience since the bi-dimensionality of the screen. So in the latter years the virtual reality is becoming more and more accomplished by new hardware interfaces capable to increase the realism degree. Among all, the sensorized glove is becoming one of the more interesting and promising of these interfaces. Here we propose the electronic interface and signal conditioning circuitry we adopt as the most suitable for our developed data glove system. The same solution we adopted can be usefully extended for other specific systems that treat signals coming from sensors which read kinematics from disabled persons with reduced Range Of Motion (ROM) capabilities.
