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.

First claim

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, wherein 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.

2 . The mobile device according to claim 1 , wherein the at least one controller is configured to periodically conjecture whether the mobile device that has been immersed in water is out of the water on the basis of detection results obtained by the touch screen.

3 . The mobile device according to claim 1 , wherein after conjecturing whether the mobile device that has been immersed in water is out of the water on the basis of the detection result obtained by the touch screen, the at least one controller is configured to conjecture whether the mobile device is immersed in water on the basis of a detection result obtained by the touch screen.

4 . The mobile device according to claim 1 , wherein 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 output values at detection points on the touch screen.

5 . The mobile device according to claim 1 , further comprising a housing, wherein
the atmospheric pressure sensor is positioned on an inside of the housing, the housing includes:
a hole configured to connect a space on the inside of the housing in which the atmospheric pressure sensor is positioned to an outside of the housing; and
a ventilation valve provided at a boundary between the hole and the outside of the housing, and
the ventilation valve has a water retention function to retain water.

6 . The mobile device according to claim 5 , wherein
the ventilation valve includes a member made of cloth, and the ventilation valve has the water retention function realized by the member made of cloth.

7 . A mobile device comprising:
an atmospheric pressure sensor configured to detect a value of atmospheric pressure; and at least one controller configured to use the value of the atmospheric pressure in an application being executed thereby, wherein the at least one controller is configured to input predetermined data into the application when having determined that the mobile device is immersed in water on the basis of a change in the value of the atmospheric pressure.

8 . The mobile device according to claim 7 , wherein the predetermined data includes at least one of data indicating that the mobile device is immersed in water, data indicating that a value of water pressure is exhibited, and data indicating that the value of the atmospheric pressure is not exhibited.

9 . The mobile device according to claim 7 , wherein the at least one controller is configured to discontinue using the value of the atmospheric pressure in the application, when having determined that the mobile device is immersed in water on the basis of the change in the value of the atmospheric pressure.

10 . The mobile device according to claim 9 , wherein the at least one controller is configured to use, in the application, a value that is not dependent on the detected value of the atmospheric pressure, when having determined that the mobile device is immersed in water on the basis of the change in the value of the atmospheric pressure.

11 . The mobile device according to claim 7 , wherein the at least one controller is configured to use, in the application, the value of the atmospheric pressure as a value of water pressure, when having determined that the mobile device is immersed in water on the basis of the change in the value of the atmospheric pressure.

12 . The mobile device according to claim 11 , wherein, by employing the application, the at least one controller is configured to calculate a water depth on the basis of the value of the atmospheric pressure observed before having determined that the mobile device is immersed in water and the value of the water pressure.

13 . A mobile device comprising:
an atmospheric pressure sensor configured to detect a value of atmospheric pressure; a touch screen; and at least one controller configured to use the value of the atmospheric pressure in an application being executed thereby and to input predetermined data into the application when having determined that the mobile device is immersed in water on the basis of contact points detected by the touch screen and output values at the contact points.

14 . The mobile device according to claim 13 , wherein the predetermined data includes at least one of data indicating that the mobile device is immersed in water, data indicating that a value of water pressure is exhibited, and data indicating that the value of the atmospheric pressure is not exhibited.

15 . The mobile device according to claim 14 , wherein the at least one controller is configured to use the value of the atmospheric pressure in the application being executed thereby and to discontinue using the value of the atmospheric pressure in the application when having determined that the mobile device is immersed in water on the basis of the contact points detected by the touch screen and the output values at the contact points.

16 . The mobile device according to claim 13 , wherein the at least one controller is configured to use the value of the atmospheric pressure in the application being executed thereby and to use, in the application, a value that is not dependent on the detected value of the atmospheric pressure when having determined that the mobile device is immersed in water on the basis of the contact points detected by the touch screen and the output values at the contact points.
