Abstract

An interactive education system is described for teaching patient care to a user. The system comprises a patient simulator, as well as a virtual instrument for use with the patient simulator in performing patient care activities. The systems also includes means for sensing an interaction between the virtual instrument and the simulator, and means for providing feedback to the user regarding the interaction between the virtual instrument and the simulator.

In a first embodiment, the simulator and virtual instrument are tangible objects, and in a second embodiment, the simulator and virtual instrument are software-generated objects.
