Sensory Feedback in a Serious Gaming Environment and Virtual Reality for Training Upper Limb Amputees

In this article, the authors present a system based on Immersive Virtual Reality and Serious Games for training the use of prostheses by upper limb amputees with a tactile feedback. By using EMG signal processing, users can control the opening and closing of a virtual prosthesis, just like in real life. Tactile feedback causes an improvement in the sensation of touch. Tests were carried out with separate groups: with and without sensory feedback with amputated and non-amputee volunteers. Tests in which users who received haptic feedback demonstrated improvements in performance compared to those who did not use haptic feedback.
