Normally, bedridden patients need nurses to help moving their body or changing lying positions. However, to patients, changing lying positions by others may cause two problems: One is the timing and frequency of movement may not be adequate and the other is the cozy position of the movement may not be perfect for patients. Therefore, in this study, we tried to build up a handy system which can help bedridden patients to control hospital beds in several lying positions that match their preferences closely by only moving their eyes. In the results, we have already built up an eyecontrolled equipment which allowed user to control hospital beds by themselves. This equipment had advantages of light and handy. Besides, we also constructed a model of our homemade hospital bed with six specific bed boards. This new type may help users to change their lying positions in left right tilt. Although there still have some tests to be conducted, the system of using eye control on our new type of hospital bed is possible. In the future, we expect that this handy system can help bedridden patients to appropriately control hospital beds in several lying positions that match their preferences closely by only moving their eyes.
