Enumerate the use of Data goggles- Virtual Reality

Data goggles/helmets - These use optical systems and display screens which send 3D images to the eyes. Motion sensors measure the orientation and position of the head; this information is sent back to a computer that enables it to adjust the image being sent to user. Data gloves, joysticks and suits containing sensors are all used to interface with a virtual reality system depending on application.

CAVE is a VR system that provides the illusion of 3D by projecting images on the walls and floor of a room. Participants wearing data goggles can enter the room and freely walk about. Sensors in goggles and in the room continually track participants' position and adjust images based on this information.
