Experimental study toward mutual adaptive interface

An experimental study towards the mutual adaptive interface has been performed in order to validate the effectiveness of the adaptive mechanism based on the estimated human state. The Mental Work Load (MWL), which is estimated based on the physiological measures, has been taken as a representative index of the subject and used to control the task difficulty in the example task (X-window-based game, called X-jewel). The results of the laboratory experiments showed the positive effect in the performance score, which implies the effectiveness of the adaptive mechanism in the present task domain
