An information processing device includes a touchscreen that includes a first surface that outputs images and detects an input to the first surface, a sensor that detects whether a switching device is mounted an the touchscreen, and processing circuitry. The processing circuitry is configured to control a display state of the touchscreen based on a detection result of the sensor so that the touchscreen outputs in a first display mode when the switching device is not mounted on the touchscreen, and the touchscreen outputs in a second display mode when the switching device is mounted on the touchscreen.
