Abstract

A basic control process is performed on a mobile phone. From the basic control process, various processes are branched and performed, such as a normal standby process, unread mail reading standby process, and Braille pattern data generation process. In each of the processes, each of the Braille pins of a Braille display device provided for the mobile phone is raised, as occasion demands, by drive-control performed by a Braille driving device, and for example, the content of an unread mail, the content of a creating email, and a phone number in a phone call or the like on the mobile phone are displayed as a Braille pattern. The raising direction of the Braille pins is set on the rear surface different from the operation surface of the mobile phone. Thus, while holding the mobile phone in one hand, a user can perform the operation related to the phone call or email and can quickly and accurately perceive or sense various text information displayed in Braille.
