Abstract: An electronic device is provided with a touch panel of a capacitive type and a controller. The controller, based on a detection value of the touch panel, detects capacitance generated between the touch panel and a contact object and detects, as a contact region, a first region having the capacitance smaller than a capacitance of the other region of the touch panel.

Abstract: A mobile device includes an acceleration sensor, a touch screen and a controller. The acceleration sensor is capable of detecting a direction and a magnitude of acceleration acting on the mobile device. The touch screen is capable of measuring electrostatic distribution. The controller is capable of executing an estimation whether the mobile device is being immersed in water based on the electrostatic distribution. The controller periodically executes the estimation upon determining that the mobile device is moving in a direction opposite to a gravity direction based on the direction and the magnitude of the acceleration when estimating that the mobile device is being immersed in water.

Abstract: A mobile device according to one of a plurality of aspects comprises an atmospheric pressure sensor configured to measure a value of atmospheric pressure, a touch screen, and at least one controller configured to conjecture that the mobile device is immersed in water when the value of the atmospheric pressure satisfies a condition. The at least one controller is configured to conjecture whether the mobile device that has been immersed in water is out of the water on the basis of a detection result obtained by the touch screen. The mobile device is able to determine whether the mobile device is immersed in water and whether the mobile device is out of the water, while keeping the electric power consumption low, due to using the touch screen only when determining whether the mobile device is out of the water.
