Abstract: A sensor system according to an embodiment of the present invention includes: a sensor module including a sensor panel arranged on a display panel; and a processor capable of driving the sensor module in a noncontact manner, wherein the processor is configured to detect a first input operation based on a detection target approaching the sensor panel, and then measure an amount of movement from a first point based on movement of the detection target in a direction away from the sensor panel after the detection target approaches the sensor panel up to the first point, and detect a second input operation based on a criterion different from the first input operation when the detection target approaches the sensor panel again after the amount of movement exceeds a threshold value.
