Virtual reality has been proposed for different applications, including the evaluationof new control strategies and training protocols for upper limb prostheses and for the study ofnew rehabilitation programs. In this study, a lower limb simulation environment commandedby surface electromyography signals is proposed. The time delays generated by the acquisitionand processing stages for the signals that would command the knee joint, were measured anddifferent acquisition windows were analysed. The subjective perception of the quality ofsimulation was also evaluated when extra delays were added to the process, in order to evaluatethe impact of the delays in subjective perception. The results showed that the acquisitionwindow is responsible for the longest delay. Also, the basic implemented processes allowed forthe acquisition of three signal channels for commanding the simulation. Finally, thecommunication between different applications is arguably efficient, although it depends on theamount of data to be sent.
