A voice-control-aid registration and tracking system using NDI Polaris

This paper describes an on site registration system for facial point data. This system registers two facial point datasets from the floating dataset obtained from NDI Polaris equipment to the reference dataset extracted from CT images. To benefit the user's flexibility on using Polaris without the remote assistant's help, the voice command ability is added into the system. The user is able to control the procedure and examine the data via his voice without the remote assistant as a traditional way of using Polaris. This system offers different display functions such as point-data, mesh and polygonal functions for the registration results, and is able to track the probe position in the registration result and the CT images.
