PROBLEM TO BE SOLVED: To provide a self-propelled vehicle capable of being input the operation information by minimum movement of an input directing body such as fingers. SOLUTION: An electric wheelchair 1 uses an optical operation input device 100 using infrared ray to input the operation for the wheelchair body 10, so a small movement of a finger Ob1 can perform the operational input. It makes it possible that a disable person can operate the wheelchair body 10 even if he or she can not operate the operation lever by hand or voice input. Additionally the electric wheelchair 1 can run safely because it has an optical detecting device 200 for detecting obstacles by using infrared ray. COPYRIGHT: (C)2011,JPO&INPIT
