Virtual reality has been used in many areas of application, from training to simulation. There is an increasing interest in using VR for training persons for prosthetic limb control. In a prosthesis, a myoelectric signal map to the velocity or position of a prosthetic joint. There is little evidence on what is the appropriate mapping between the myoelectric input and the prosthetic joint output. There is a possibility that a poor mapping will hinder the training. This study is the first stage in the process to understand this mapping, by studying the distribution of velocities in the intact arm in a conventional Fitts law test. What is observed is a wide range of velocities, decreasing in frequency as the velocity increases. This implies that for VR training to be effective a wide range of velocities need to be used in that training.
