Windows on the world 论文

摘要

We describe the design and implementation of a prototype heads-up window system intended for use in a 3D environment. Our system includes a see-through head-mounted display that runs a full X server whose image is overlaid on the user's view of the physical world. The user's head is tracked so that the display indexes into a large X bitmap, effectively placing the user inside a display space that is mapped onto part of a surrounding virtual sphere. By tracking the user's body, and interpreting head motion relative to it, we create a portable information surround that envelopes the user as they move about.
