Abstract
A position detection device includes 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, and outputs the first position and the second position that have been detected. The controller controls the output of the second position based on the acceleration information received by the communication circuit.
Claims20
A position detection device comprising:
- 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.
A non-transitory computer-readable storage medium storing a program that, when executed by one or more processors, causes a computer, which includes a communication circuit that receives, from a stylus including a built-in acceleration sensor, acceleration information detected by the acceleration sensor, to:
- detect 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;
- output the first position;
- determine whether there has been a change in the acceleration information received for a predetermined period of time by the communication circuit;
- and
- control 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.
