Description

  The present invention relates to a display input method for a mobile phone that facilitates display input of information such as characters and images in a mobile phone, for example.

Conventionally, in a mobile phone, about 12 keys are set with numbers, kana characters, and alphabets, and the mode is changed using the mode key for switching the input mode, and the mode is switched to the numeric input mode, the kana input mode, the alphabet input mode, etc. You are typing.
In such a cellular phone, since the key is small and the key must be pressed many times, the fatigue of the finger is severe and the key may be small.

In particular, a key input method for inputting with a reduced number of keys has been proposed for cellular phones because the number of keystrokes is increased and input operability is poor (for example, Patent Document 1).
In addition, there is a mobile phone that is folded in half, and a display unit and a key unit (input unit) are separated to increase individual keys in the key unit (for example, Patent Document 2).

  However, even with such a two-fold mobile phone, the display part is still small and the key part is also small, especially for elderly people, it is bothersome to see characters on the display part and to input characters from the key part The nature was bad.

  Japanese Patent Publication No. 2005-4500   Japanese Patent Publication No. 2004-48719
