TEXT ENTRY VIA PALMTM HANDHELD IN AN IMMERSIVE VIRTUAL ENVIRONMENT

摘要

There is a need for text entry capability in immersive virtual reality environments such as the CAVE. Existing text entry devices distract users from the immersive experience at best, and remove them from it at worst. An implementation of a text entry method using a handheld personal digital assistant (PDA) to communicate with a CAVE application is described. To reduce the complexity of navigating with one device and entering text with another, several navigation methods using a Palmm handheld have been devised. Their merits are discussed. One of these, a point-and-stroke navigation method, is simple, effective, and well suited to any application using a handheld computer for navigation inside a mappable environment.
