Abstract
We described about a rehabilitation system for lower limbs using floor projection type serious game in this paper. In this system, the target is displayed on the floor, and when the user steps on the target, the target disappears and the score is added. Shoot the movement of the user’s foot with a TV camera and judge whether or not the target has been stepped by using image processing. The user stands in front of the display area, steps on the target as the target appears. When the target disappears, put the foot back and return to the first posture. By repeating this movement, the user can exercise the lower limbs. The exercise performed in this system is called a Step Exercise and is commonly performed as rehabilitation effective for improving the sense of balance and increasing the muscular strength of the lower limbs. We measured the number that could be erased and the number that could not be erased (the number the system did not respond) when stepping on the target by the foot, and calculated the error rate. The experiment time was 90 s. As a result, the error rate was 4.7%, and the success rate was 95.3%. This was a very high recognition rate. We could judge this system has sufficiently practical accuracy as a floor projection type serious game system for lower limb rehabilitation.
