This CD is now provided to all first year students for home use prior to their introduction to the manikin lab and has been an aid in the learning process. All students must satisfactorily complete this first phase before beginning the simulation system.

A variety of motion capture systems have been developed, including gloves, body suits and motion trackers. These technologies can capture, trace and evaluate motion for a variety of purposes, including ergonomics studies. In this project we adapted currently available spatial tracking technology (MiniBird motion tracker) to trace the 3D movements and paths of a dental cleaning instrument as it removes deposits from the root surface of a tooth. To accomplish this the scaler was attached to the motion tracker sensor. The scaler was used to perform a Sc/Rp procedure by the instructor using a standard laboratory plastic tooth and manikin model currently used to train students. The path information collected by the scaler/sensor was converted to a graphic representation of the data. This data was converted to a directional graphic showing the student the path to follow for proper Sc/Rp. An audible signal was added to the directional graphic path to notify the student if he/she veered off the correct Sc/Rp direction during the movement of the scaler.
This phase of the project was supported by a grant from UIC's Council For Excellence in Teaching and Learning.
