A Compact and Low-cost VR Tooth Drill Training System using Mobile HMD and Stylus Smartphone

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Drilling teeth is a significant technique for dental learners. However, the existing VR tooth drill training simulators are physically large and costly, which cannot be used at home or classroom for a private study. This work presents a novel low-cost mobile VR dental simulator using off-the-shelf devices, including a mobile HMD and a stylus smartphone. In this system, a 3D-printed physical teeth prop is placed on an EMR stylus smartphone where its stylus tracks the tip position of a physical drill. Unlike existing solutions using haptic/force devices, our approach involving physical contact between the prop and drill tip enables the user’s natural teeth hardness sensation. The use of smartphone stylus would enable significantly more accurate drill position sensing around the teeth than HMD’s accompanying controllers. We also developed VR software to simulate tooth drilling on this setup. This demo will show how our new mobile simulator offers a realistic feeling of drilling teeth.
