Tracking has been since the beginning of Virtual Reality the core task of any VR application. In particular, hand tracking has been addressed only in the last decade thanks to the improvement in the field of technologies and computer vision. Although modern hand tracking system such as Kinect or Leap Motion are already on the market, there still are not standard solutions or approach. Hand tracking will be crucial in VR application as this can allow the user to interact with the virtual environment without the use of metaphors, therefore boosting the feeling of immersion and presence. Another important instrument of any virtual application is the capability to give to the user some sort of feedback (for example a joystick that can vibrate). In this thesis we propose a new method to track the user hand and give an electric feedback when needed. Specifically the tracking is performed using infra-red led and a tracking system made by Optitrack, and a microcontroller driving the infrared led. Everything is managed by a client executing on the PC. The electric feedback is managed by the virtual environment also executing on the PC but the actual electric pulse is driven by the microcontroller.
