Description

Description Portable text input device Technical field

The present invention relates to a character input device, and more particularly, to a key input device for a mobile phone, a pen input device for a computer device, and a key input device for a portable information processing device such as a PDA. The present invention provides a portable character input device capable of performing quicker character input by using. Background art

In a portable information processing device such as a mobile phone, the area for arranging keys is small, so that only a limited number of keys can be arranged. Therefore, many key operations were required to input one character.

In the case of a conventional mobile phone, when inputting kana characters, for example, as shown in Fig. 1, the five characters "Pia, Re, Uu, E, O" corresponding to the row of the 50-tone array Was assigned to one key, and the corresponding character was input according to the number of times the key was pressed (the slicing method). In other words, for example, for a key that is assigned "A, Re, U, E, E", pressing the key once will result in the input of "A", and pressing it twice will result in the input of "I", Similarly, "U" is input three times, "E" is input four times, and "O" is input five times. Thus, on average, three key presses are required. When inputting alphabetic characters, for example, a plurality of alphabetic characters are assigned to one key in alphabetical order, and similarly, the corresponding character is input according to the number of times the key is pressed.

The technology of Japanese Patent Application No. 7-333056 was proposed as a method of inputting characters using fewer keys. However, several key presses were required to input characters that were input with a single key press on a normal keyboard, for example, "U". In other words, there was a problem that frequently entered characters such as “A, Re, U, E, O” required two key presses. In addition, five steps of key presses were required to enter a vowel with a vowel "u"("ko","so","to", ...). Also, in a device such as a mobile phone, since numerical values are frequently input, it is not desirable to change the arrangement of numerical values (three-column key arrangement). However, since the above technology is suitable for a two-column or two-row key layout, there was a problem in applying it to a three-column key layout for mobile phones and the like.

Therefore, with the spread of mobile phones in recent years, it is possible to input characters suitable for a three-row key layout of mobile phones, etc., and to input frequently used characters such as “A, Re, U, E, O” once. There is a need for a portable character input device that can be entered by pressing a key.
