Over the past twenty years, groups of therapists, researchers and engineers have seized the potential of virtual reality (VR) and its associated technologies to work together on designing and testing a great variety of rehabilitation devices and systems with the objective of improving the support for people with disabilities. Virtual reality technologies offer new paradigms for human exploration, understanding and support by providing participants a safe setting in which they can interact and develop goal-oriented activities within functional-virtual environments, especially when they find themselves in situations of cognitive, behavioural or motor disabilities. The solutions built from these technologies reduce patients' limitations of activity and participation by promoting the recovery of capabilities. The current diversification of VR technology can also lead to tools used at home so that the patient can pursue the training that was initiated with the therapist in the care centre. In this book you will find research on the rehabilitation in motor, cognitive and sensorial disorders.
