Abstract: A touch system is provided. The touch system includes a touch tool and a touch panel. The touch tool provides a downlink signal. The touch panel obtains a first sensing area sensed with the touch tool, and obtains a second sensing area other than the first sensing area according to the downlink signal. The touch panel provides a first uplink signal to the first sensing area, and provides a second uplink signal to the second sensing area. The first uplink signal is different from the second uplink signal. The touch tool generates a calculated uplink signal according to the first uplink signal and the second uplink signal, and provides the downlink signal according to the calculated uplink signal.
