Virtual Reality Simulation of High Tibial Osteotomy for Medical Training

Figure 2

Prototype of morphable haptic controller proposed in this simulation. This device is cylinder shape and has the function of length deformation, the center of mass movement, and vibration. (i) Tactile morphing pad. It controls the controller and provides a sense of vibration to the user. (ii) The location where the length deformation occurs. The length is stretched or shortened by the electroactive polymer actuator inside the controller. (iii) The handle of the controller. Inside the controller, the center of mass module moves to provide a sense of the weight of the tool that the user equips in the simulation.
