| In computer-assisted surgery, a computer display provides 3D guidance of tools during surgery. However, current guidance displays have a number of drawbacks.;This thesis considers the advantages of a prototype guidance system for drilling tasks. A small LCD screen and video camera was attached to a surgical drill. The screen's point of view was controlled by moving the drill.;A user study showed that the tool-mounted LCD screen can provide significantly better positional and angular accuracy than the conventional display. The study also showed that a video camera might not be useful for guidance. |
