In this study, we investigated, analyzed and developed a new version of an Augmented Reality Game Based Stroke TeleRehabilitation (AR-GBSTR) system. Using Augmented Reality, a means of human-computer interaction in which users can perceive and interact with virtual objects juxtaposed with physical objects, we hope to provide cheaper and more varied experiences for stroke survivors using Game Based Stroke TeleRehabilitation. In a prior study, AR-GBSTR resulted in better outcomes compared to traditional game based stroke telerehabilitation in the activity that was tested. This version was too costly to reproduce and hence not scalable. Additionally, it had limited functionality. AR-GBSTR version 2 is an attempt at developing a lower cost, more scalable system through the use of IoT sensors, effectors, and controllers. For this study, we assembled a portable table-top system that includes a 22 in. multi-touch touchscreen and an Intel RealSense hand tracking sensor, which are powered by a Minix miniature portable computer that runs a custom built collection of games developed in the Unity 5 game engine. By using these devices we are able to reproduce the proven functionality of the earlier AR-GBSTR system and add several new means of interaction for stroke survivors. Time permitting we will conclude our presentation by a demonstration of our final system to the audience.
