If my patient feels a bit uncomfortable using the virtual reality goggles, may I train him by showing the stimuli in the computer display?
It is not recommended because the rehabilitation could be ineffective. The patient needs to be isolated from the environment to receive pure stimuli. With the virtual reality goggles and the darkening of the room, the only visual reference received will be the stimuli projected on the virtual reality goggles. Another important reason is that the virtual reality goggles and the head tracker combined are used to generate stimuli combining visual and vestibular functions. These functions are impossible to combine if the stimuli were projected in the computer display.
