Virtual world presented full scale, proportioned to human size Realistic interactions with virtual objects via data glove and similar devices allow manipulation, operation, and control of virtual worlds Illusion of being fully immersed in an artificial world enhanced by auditory and other non-visual technologies Networked applications allow for shared virtual environments </li> <li> Slide 16 </li> <li> Challenges in VR design Interactivity real-time systems system must respond to user inputs without any perceptible delay Real-time constraint fast computation and graphics 3D interface design Tracking hardware High-resolution display hardware Must be compelling! </li> </ul>
