ImGTS for Patients With Cerebral Palsy and With Mobility Limitations

The Semi-CAVE will use two screens positioned at a corner of the room, each with a ceiling-mounted short throw projector in front. The participant will stand in the middle of the area, giving them a viewing angle of roughly 180 degrees. The participant will be wearing a safety harness secured to an overhead guide rail, if necessary. The participant may be standing freely, on a treadmill, or on a step stool depending on the type of activity to be performed. The participant will interact with the system through motion sensors positioned at the corners of the area. To one side of the area will be a sufficiently powerful computer running the software. The projectors will be connected to this computer via HDMI cables or similar.

The HMD will be a commercially available device that uses handheld controllers to control movement while in the VE. The researchers will use a room-scale set-up where a 3 m x 3 m square space is required. Oculus Quest 2 Controllers will be used to interact with the VE. The user will be positioned at the center of the square by default. A therapist will assist them through a separate program called the Observation Module. This program will let the therapist view what the patient can see in the HMD. This will also be used by the therapist to guide the patient navigate through the VE and give instructions for the activities.
