Embodiment Construction

[0031] Examples of the present invention are described below. The car navigation device 1 will be described below as a character input device in this embodiment. Such as figure 1 As shown, a car navigation device 1 is installed in a vehicle, and has a position detection device 11 , an image display device 12 , an operation part 13 , a speaker 14 , a map data collection part 16 and a control circuit 17 .

[0032] The position detection device 11 has known sensors such as a geomagnetic sensor, a gyroscope, a vehicle speed sensor, and a GPS (Global Positioning System) receiver. These sensors respectively output information specifying a current position, a traveling direction, and a vehicle speed to the control circuit 17 . The image display device 12 displays an image according to the video signal output from the control circuit 17 .

[0033] The operation section 13 has input devices such as a plurality of mechanical switches 13 a provided on the car navigation device 1 or to...

Abstract

A Japanese Hiragana input character string of 'a-i' is displayed while a single Japanese Hiragana character of 'ti' is displayed as a display character for representing a 'ta' row key assigned with a 'ta' row character group of 'ta', 'ti', 'tu', 'te', and 'to'. When a user then appoints the 'ta' row key, 'ti' is added to the tail end of the input character string to newly form the input character string of 'a-i-ti' containing three characters. When each of 'ka' and 'ki' does not effectively follow 'a-i-ti' in tree structure index data, a display character for a 'ka' row key assigned with 'ka', 'ki', 'ku', 'ke', 'ko' is switched into 'ku' while skipping 'ka' and 'ki'. Further, when 'tu' does not effectively follow 'a-i-ti' in the index data, a display character for the 'ta' row key is switched from 'ti' into 'te' while skipping 'tu'.

Description

technical field [0001] The present invention relates to a character input receiving device and a method for receiving character input. Background technique [0002] There is known a character input technique in which, when character input keys are displayed on an image display device and a user points to the displayed character input key, a character currently assigned to the pointed character input key is displayed as an input character. [0003] For example, in a car navigation device, a plurality of input keys are displayed and assigned to a plurality of characters, respectively. Among Japanese characters, approximately fifty input keys are each assigned a Hiragana character. Also, in English, approximately twenty input keys are each assigned an alphabetic character. [0004] In such a method, there are many input keys to be displayed, so it is difficult to accommodate them within the size of one display window. If a plurality of character input keys are displayed on o...
