a communication circuit which, in operation, receives, from a stylus including a built-in acceleration sensor, acceleration information detected by the acceleration sensor; and
a controller which, in operation, detects a first position indicating a position of the stylus on a touch surface and a second position indicating a position of a finger on the touch surface, outputs the first position, determines whether there has been a change in the acceleration information received for a predetermined period of time by the communication circuit, and controls output of the second position based on whether there has been the change in the acceleration information received for the predetermined period of time by the communication circuit.
