Power wheelchair Sports have been becoming widespread, especially for disabled people. We developed a system that could spread Power Wheelchair Tennis into virtual spaces with good force feedback and a more authentic experience. Tennis game development in VR is based on Unity, a 3D game engine. Operation from a joystick interface helped control the movement of the wheelchair both in virtual space and reality. To enhance the immersive realism by feeding motion in the VR space back to reality. The force feedback comes from a real racket on the side of the power wheelchair. The system presented vibration feedback when hitting the ball through a joystick, and a 6DoF Electric suspension platform that can tilt the seat surface when moving or rotating. The project is supported by EMP Challenge Grant.

With the development of sensor accuracy and optimization algorithms, the Advanced Driver Assistance System (ADAS) has been widely used on vehicles to achieve level 3 of automatic driving. Vision-based dense mapping is one of the most essential solutions in ADAS to help vehicles sense surroundings. However, traditional methods could only reconstruct a 3D map of a static environment because of the occlusion of dynamic objects on the environment map. Moreover, a dynamic environment is hard to be 3D modeled in real time because of the limitation of computing power and algorithm complexity. To make the dynamic scene visible in a 3D point cloud, we propose a system that superimposes dynamic objects on a static environment in real-time. The static environment is reconstructed by aerial multi-view images from the unmanned aerial vehicle (UAV) in advance to reduce the required computing power. Dynamic objects point cloud is generated from disparity maps generated by a consumer stereo-camera frame by frame. 

This project investigates the effects of real time visual biofeedback for improving sports performance using a large scale immersive mixed reality system in which users are able to play a simulated game of curling. The users slide custom curling stones across the floor onto a projected target whose size is dictated by the user's stress-related physiological measure; heart rate (HR). The higher HR the player has, the smaller the target will be, and vice-versa. In the experiment participants were asked to compete in three different conditions: baseline, with and without the proposed biofeedback. The results show that when providing a visual representation of the player's HR or "choking" in competition, it helped the player understand their condition and improve competition performance.
