Problem statement

We have develop a system for get an interaction between a patient and a 3D model in a virtual reality auditorium and prosthetic myoelectric training system.

That was fully designed at the Mechanical Design and Technological Innovation Centre, UNAM.

Virtual Reality

• A myoelectric signal gives the order to activate the displayed hand on the theatre, and a prosthetic hand opens and closes the fingers according to the signals.

3D model

1. The user moves their muscles and send an activation signal for the training card.

2. The training card gets the voltage and translate it in to a movement.

3. The training card send de move order to the vision system.

4. The vision system, displays in real time the position that was established previously.
