Let disabled patient can transfer their body information to nursing aide and communicate with people by using the eye tracker. In recent years, the eye tracking technology has been grown up and the calibration ability of eye tracking is faster and more precise than before. The eye tracking can provide a precise control at human-computer interaction. Most eye trackers are developed for psychology analysis by collecting eye gaze data, e.g., detecting the area where a user looks most. We develop a system interface called “Body Information Transmission Function” that placed a human body image, and let patient gaze the area of body feature to transmit the information to nursing aide. With the “Common Words Function”, patient can do simple communicate with his family or friends. This function also can customize the interface according to the patient’s request. Besides, we set the threshold to trigger the mouse click event. The body information transmission function can quickly let patient transmits his abnormal body parts to nursing aide. Let nursing aide can get the information through normal medical equipment, but also can quickly and accurately obtain the abnormal body parts from patients themselves when they deal with patients problem. It can improve the accuracy and response time of the abnormal condition of the judgment that. And, let nursing aide can deal with the problem in a quickly time. The common words function provides the patient doing simple communication with his family and friends by selecting the common words. It can improve the quality of patient’s daily life, and the high flexibility of this function provides customizing system according to patient’s request. Let patients can use this function more effectively. Through setting the threshold of selecting time, the input method of this system can improve the accuracy of input and decrease the probability of error input. It im-proves the effective of system usability.
