Abstract

Input/Output systems and processes for computer assisted surgery systems are described. In one embodiment, a rendering apparatus is adapted to render display information on a presentation substrate during surgery. A plurality of location indicia are attached to the presentation substrate and a sensor senses the position and orientation of the location indicia. A computer functionality determines the position and orientation of the presentation substrate from the information from the sensor on the position of the location indicia. The computer functionality coordinates the rendering apparatus with the position of the display substrate so that the rendering apparatus renders display information onto the presentation substrate used in surgery. In another embodiment, the rendering apparatus renders interaction indicia onto a presentation substrate and a monitoring apparatus monitors interaction with the interaction indicia to allow data to be input into the computer functionality by way of the interaction indicia.
