An intravenous injection simulator using augmented reality for veterinary education and its evaluation.

This paper proposes a simulator for veterinary education based on augmented reality. We selected an intravenous injection procedure for the simulation because the injection procedure is the most frequently used procedure during veterinary training and the most difficult stage for beginning veterinary students. The proposed AR simulator provides with a tangible prop, of which shape looks like a leg of a real dog. It also has an injection simulator, which receives user's input and sends force feedbacks to indicate results of the injection simulation. We developed a Workbench type AR system with an LED display and cameras for visual information processing. Finally, we evaluated its performance through experiments and user studies to check its acceptance level and usability of the proposed system. We compared the proposed system with a VR based system using a monitor. The results showed that the proposed system showed better performances over these systems.
