Development of real-time haptic application

This on going research focuses on developing a PC/NT based realtime, virtual reality haptic application. Our main goal is to resolve the critical real-time issues required to develop a stable haptic application. Critical real-time issues addressed include: (1) interprocess communication, (2) synchronization of haptic and graphics interface and (3) finding application size limits for achieving high haptic rendering rates with stable haptic interactions. We are using a breast biopsy simulator prototype as an example to show the viability of developing such a system. This system monitors and indirectly guides the surgeon's movements by providing high fidelity visual and force feedback cues as the area of surgical interest is approached
