Mirror therapy is used from many years to treat phantom limb pain in amputees. However, this approach presents several limitations that could be overcome using the possibilities of new technologies. In this paper we present a novel approach based on augmented reality, 3D tracking and 3D modeling to enhance the capabilities of the classic mirror therapy. The system was conceived to be integrated in a three steps treatment called “Graded motor imagery” that includes: limb laterality recognition, motor imagery and, finally, mirror therapy. Aiming at a future home care therapy, we chose to work with low-cost technologies studying their advantages and drawbacks. In this paper, we present the conception and a first qualitative evaluation of the developed system.
