An electronic system control method, applied to an electronic system comprising a host device and a peripheral device, comprising: generating portrait location information and land scape location information, by the peripheral device; judging a host operation mode of the host device; and selectively using the portrait location information or the land scape location information to compute a location of the peripheral device or of an object on the peripheral device, corresponding to the host operation mode. By this way, the peripheral operation mode may be automatically set corresponding to the host operation mode. In one example, the peripheral device have at least one control button which has different functions in different modes.
