The objective of this paper is to present a Mixed Reality System for Serious Games (MRSGS )used for the rehabilitation of the upper limb after stroke. The system answers the following challenges: (i) increase motivation of patients by making the training a personalized experience; (ii) take into account patients' impairments by offering intuitive and easy to use interaction modalities; (iii) make it possible to therapists to track patient's activities and to evaluate/track their progress; (iv) open opportunities for telemedicine and tele rehabilitation; (v) and provide an economically acceptable system by reducing both equipment and management costs. In order to test this system a pilot study has been conducted in conjunction with a French hospital to understand the potential and benefits of mixed reality. The pilot involved 3 therapists who 'played the role' of patients. Three sessions, one using conventional rehabilitation, another using an ad hoc developed game on a PC, and another using a mixed reality version of the same game were held. Results have shown the MRS and the PC game to be accepted more than physical rehabilitation.

In this paper we propose a mixed reality system (MRS) and an adaptation module for rehabilitation of the upper limb after stroke through serious games. Aim of the system is to increase intensity and number of training session using the fun factor as driver. Although our system is targeting post stroke patient it is necessary to validate and test our approach with valid users at the first stage to provide patients with stable system to use. These studies and their results are described in this paper.
