**8. Conclusions**

We developed a rehabilitation system using a haptic device that integrates both motion and sensory therapy. The system is designed to maintain the user's interest during a rehabilitation activity and also to provide a quantitative evaluation for occupational therapists. From the results of experiments with kindergarten children, a negative correlation of duration time and motion error was confirmed in the two different cases of applied force and no force applied. In addition, the motion error decreased according to age. It was found that this developed system effectively motivated and evaluated hand-eye coordination.
