Computer-aided engineering. Technician using a computer-aided design (CAD) package to design an engineering component. He is wearing glasses which make the screen image appear in three dimensions. Sensors on the triangular frame above the screen are monitoring the position of the device in the technician's hand. By moving his hand, the technician can affect the shape of the component on the screen - the system acting as a virtual reality lathe. CAD is an important tool in industrial design, allowing the structure to be viewed from any angle and rapidly calculating the effect of any changes.
