A touch method and a touch system using the same are disclosed. The touch system comprises a display panel and an image sensing module. The touch method comprises the following steps: detecting and acquiring a coordinate position of a touch object entering a sensing region of the display panel; determining whether the touch object is moving or situated at a fixed point according to the coordinate position; sensing a first reflective luminance generated by the touch object at a point via the image sensing module; sensing a second reflective luminance generated by the touch object at the point via the image sensing module after a time period; comparing the first and the second reflective luminance; if the first reflective luminance is different from the second reflective luminance, then determining that the touch object is performing a fixed point rotation; executing a corresponding instruction according to the fixed point rotation.
