Abstract
In this research, combination of haptic display technology and ultrasonic elasticity imaging technology is attempted. The system can provide living body elasticity information in a three-dimensional space as sense of sight information and sense of force information. To realize the system, Haptic rendering method is proposed, which can consider the effect of 3D distribution of elasticity to reproduce reaction force. Reaction force can touch from arbitrary direction. The sight information is displayed quasi-biological body using OpenGL and NURBS surface. Distortion such as a human body is expressed by NURBS. The system can diagnose from arbitrary direction by improving displacement filter. It was verified by experiments on the accuracy of the displacement filter. It was possible to identify even from any direction as a result.
