Haptic interaction program systems development as a part of virtual environment

Abstract

In the paper a haptic interaction significance in virtual environments presented. Benefits of haptic interaction in virtual environments and architecture of haptic application are discussed. For the obtained results, Sensable PHANToM Omni device is used, and for that reason Open Haptic developing library for Sensable devices is shown in this paper. In addition, two developed systems with haptic interaction are also presented. First of which is previously developed program system for NC machining program verification based on approximate dexel approach, now extended with active stereo display and haptic interaction. User can stop simulation at any time and inspect workpiece coordinates by haptic device. Second developed program system is a system for preoperative support forreconstruction of the human knee ACL (Anterior Cruciate Ligament). System simulates position and drill orientation in contact with tibia boneby using haptic device, and calculates virtual surface on the tibia, where reconstructed ACL is to be placed.
