Setup and scenario of the MNVR-Rehab system: (a) the arrows indicate the interaction between the system and the patient. The patient wears the HMD headset; the two infrared cameras track the 3D exact location of the patient; send the information to the PC. The leap motion controller tracks the gesture of the patient, and it graphically mimics it in the virtual environment. The PC generates the virtual environment and displays in the HMD via the HTC Vive link box and the patient immerses into and navigates the virtual environment through HMD. The therapist may assist the patient during the training and monitor his/her performance on the PC. (b) The patient wears the HMD headset and is navigating the virtual environment and objects. (c) A screenshot of a typical scene in the training environment; (d) a screenshot when the patient moves a virtual ball into a virtual basket using her left virtual limb; and (e) a screenshot when the patient moves the ball into the basket using her both virtual limbs together
