Virtual hand in Physiotherapy for Broken bones

How it Works
The project presents techniques for simulating the motion of a human hand on a computer graphics display. This simulation is based on a generic 3D model of the human hand in which the bone structure is described as an articulated linkage. Soft tissue around the bones is represented using mass-spring meshes. A predictor-corrector method, including the treatment of incompressibility and collision constraints, is used to compute soft-tissue deformation while bones are moving. Tendons responsible for the movement of the fingers are not explicitly represented as distinct objects, but their mechanical effect on the bone structure (application of forces) is included in our model. The implemented software simulates a human hand, including bone movement, soft-tissue deformation, and collision handling, at interactive rates on a PC. This software may be used as a tool to teach anatomy or simulate surgical operations, the system was fully developed using VB.NET programming language and Math lab.
