Tetra-Sport consists of two sports activities, adaptive skiing experience (Tetra-Ski), and adaptive sailing experience (Tetra-Sail). Both experiences utilize a collaborative control scheme (Shared-Control) between the user and the instructor. This control scheme allowed Individuals with tetraplegia to have a usable and accessible sport experience while maintaining high levels of independence and autonomy. Users have the option of using a joystick or a sip-and-puff for both experiences.
