Patent ID: 8469715

Claim:
A dynamic human model comprising: a skeleton model having a plurality of bone elements coupled together by articulating joints; muscles attached to said bone elements, wherein said muscles are flexible for contracting and stretching, and wherein each said muscle has one or more optical elements disposed therein for generating a first color when said muscle is contracted and a second color when said muscle is stretched; and at least one sensor disposed in at least one of said muscles for detecting whether the at least one of said muscles is contracted, stretched, or relaxed, wherein said at least one sensor is associated with at least one of said optical elements, wherein said at least one sensor is adapted to detect movement of said muscles and the direction of movement of said muscles, further comprising a microprocessor coupled with said at least one sensor and said optical elements, wherein said microprocessor is adapted to receive signals from said at least one sensor related to whether said muscles are contracted, stretched, or relaxed and in response activate one or more of said optical elements.
