Embodiment approach 1

[0045] figure 1 It is a basic structural diagram showing Embodiment 1 of this invention. In addition, the following is an example of the search for facility names in the destination setting of the car navigation system. All devices for stepwise inputting keywords for searching, such as searching a phone book on a telephone, by combining predictive conversion and reading input.

[0046] exist figure 1 Among them, the input unit 101 receives a reading character string 102 input by the user, and a selection result 103 of presentation candidates from the car navigation system. These input results are recorded in the storage unit 109 via the control unit 108 .

[0047] When a reading character string is input from the input unit 101, the candidate search unit 104 takes out the reading input by the user from the storage unit 109, searches the facility name dictionary 105 as a keyword dictionary, and acquires the key word starting with the input reading character string. Facility...

Embodiment approach 2

[0075] Figure 9 It is a detailed configuration diagram of the presentation candidate generation unit 106 in Embodiment 2 of the present invention. The expression matching candidate generation unit 901 fetches the selection result of N words selected by the user during the candidate screening process from the storage unit 109, extracts facility name candidates starting with the above N words, and extracts the Nth word that has not been selected by the user in order of scoring. +1 word to generate a hint candidate list. The expression match candidate number determination unit 902 determines whether or not the number of elements in the presentation candidate list generated above exceeds the maximum displayable candidate number on the screen. The expression inconsistency candidate generation unit 903 extracts facility name candidates that have the same pronunciation as the N words selected by the user in the candidate screening process, but some of the words have different expre...

Abstract

Disclosed is an input support device for improving operability by considering vagueness of word breaks to present expected candidate predictions even if word breaks registered in a dictionary and word breaks of input differ, and furthermore, considering vagueness of transcription even if a transcription that differs from words registered in a dictionary is selected to present an intended predicted conversion candidate. The disclosed input support device receives an input reading string or presented candidate selection result of a user by an input device. Thereupon, a candidate search means searches for a presentation candidate using a reading based on an input or a selected presentation candidate; a word break matching candidate generation means generates a presentation candidate list of matches between selected results of a candidate screening step and word breaks on the basis of search results; a word break matching candidate number determination means determines whether the number of elements of the presentation candidate list is less than the maximum number that can be displayed, and if the result is less than the maximum number, a word break mismatching candidate generation means extracts candidates for which the selected results of the candidate screening step and the word breaks are different even though the transcriptions of the selected results match and adds the following string to the segmented presentation candidate list; and the display means displays the presentation candidate list.

Description

technical field [0001] The present invention relates to an input support device for efficiently inputting search keywords and the like in equipment such as car navigation systems and FA displays, which presents candidates for search keywords only by inputting a few pronunciations of characters. Background technique [0002] With the increasing functionality of various electronic devices, there is an increasing demand for viewing / searching electronic manuals on the devices. In addition, from the perspective of environmental issues, there is also a great need to digitize conventional paper manuals. Furthermore, a search function is also necessary in devices that use a large amount of content, such as facility name search for destination setting in a car navigation system. However, since it is difficult to input a search keyword on a device without a keyboard, which takes man-hours, there is a problem that electronic documents on the device cannot be fully utilized. Therefore...
