Virtual Objects in the Real World

with a prototype Augmented Reality system to explain simple laser printer maintenance tasks. 2 Figure 1: An Augmented Reality System. A see-through head-mounted display is connected to an image generation system to present to the user a world consisting of both virtual and real objects. Objects in the real world are affected by phenomena such as gravity, friction and collisions. Future applications of merged virtual and real environments might wish to model such phenomena; otherwise, the interaction of the two worlds may not be convincing at all. Significant work must be done before a virtual environment convincingly simulates these phenomena. Consider an office environment where the user has a virtual notepad. The merged environment would not be convincing, if when the notepad is placed on the real table, it apparently falls through the table. Similarly, in the previous example of a home-owner decorating an empty house, the home-owner might desire the addition of
