Abstract
An arm wrestling system using a 4-DOF force display with virtual human is developed for the affect display of facial color and expression, aiming for the application to training and rehabilitation support. First, the 4-DOF force display system with 4 air cylinders is developed for arm wrestling with human. By using the system, the changes of facial skin temperature as an index of emotional state and facial color associated with circulation dynamics in response to force display are simultaneously measured and analyzed. Second, on the basis of the analysis, a synthetic method for the affect display of virtual face with facial color and expression in force display is proposed, and sensory evaluation demonstrates the effectiveness of the method. Finally, by using the method, a prototype of arm wrestling system with virtual human is developed.
