Virtual Reality is defined as an interactive and multisensory computer system in which an environment is simulated in real time, and there can be two categories: Immersive Virtual Reality and Non-Immersive Virtual Reality. To date, Virtual Reality has been used in different areas such as education, entertainment and rehabilitation. The WHO estimates that around 15% of the world's population suffers from a disabling condition. This organization in conjunction with the ISPO determined that about 0.5% of the world's population requires an orthotic or prosthetic system. In Mexico, in the National Survey of Demographic Dynamics it is estimated that 10.9% of the population has difficulty walking or moving. The objective of this project is to design a Virtual Reality system that allows training transhumeral amputees in the use of the prosthesis. 2 virtual environments and 8 3D-characters were created so that the subjects to be trained can select between these possibilities to carry out the training sessions. The subjects control these 3D-characters in real time through a motion capture system, which also generates a biomechanical analysis of the movement of the shoulder during the execution of the movements.

Abstract This paper describes a virtual reality system in which the user can perform assembly tasks in a simulated workshop. This PC-based VR system integrates a force feedback device, the Rutgers Master II. It allows the user to feel the interaction with virtual tools and makes the training task in a synthetic environment closer to reality. The application also allows object manipulation with mechanical behavior, navigation, collision detection and other features.
