The invention discloses a foot control mouse and an operation method therefor. The foot control mouse comprises left and right pedals that are independent of each other and can tilt separately and automatically return, wherein tilt angle sensors are mounted in cavities of the pedals and used for sensing tilt angle changes of the pedals in real time; a single-chip microcomputer system is connected with the tilt angle sensors through an I<2>C bus; and tilt angle data is obtained through programming by a single-chip microcomputer and is sent to a receiving circuit end through a wireless transmitting circuit end to realize signal conversion. The operation method for the foot control mouse comprises the steps of operating the right pedal by using a right foot to enable the right pedal to shake and tilt in a direction so as to control a cursor to move in the corresponding tilting direction of the pedal; operating the left pedal by using a left foot to enable the left pedal to shake and tilt leftwards or rightwards and reach an angle threshold so as to realize a mouse left-right key operation; operating the left pedal by using the left foot to enable the left pedal to tilt forwards or backwards and reach the threshold so as to realize a page movement; and cooperatively operating the left and right pedals by using the left and right pedals to select a control target. The foot control mouse is simple in structure and achieves the effect of using hands and feet simultaneously.
