To enable input of information with air flow such as user's breath (expiration) without using a hand, and to enable the user to enjoy operating a mobile terminal or browsing content.
As information input means of the mobile terminal (the mobile terminal with a wind pressure sensor) 10, a wind pressure sensor 11 capable of detecting air pressure is disposed on the outer periphery of a display means 12. When the user using the mobile terminal breathes up the wind pressure sensor, a signal indicating intensity of the wind pressure is supplied from the wind pressure sensor to an CPU in the mobile terminal, and the CPU performs information processing corresponding to the signal. For example, the intensity of the wind pressure and application duration of the wind pressure are referred to, and an image to be displayed is selected and displayed on the display means based on the relation between them.
