Problems solved by technology

Therefore, there is a problem that it takes a certain amount of time until the user is presented with possible input characters, and it takes time to input a street name.
Therefore, since all street names are also searched when the second street name is input, it takes the same time as when the first street name is input before the user is prompted for possible input characters. , there is also the problem that entering the second street name takes more time

Embodiment approach 1

[0033] figure 1 It is a block diagram showing the configuration of the map information processing device according to Embodiment 1 of the present invention. exist figure 1 Among them, the input unit 1 is an operation switch group that supplies an instruction signal to the processor 4 according to a user's operation or instruction, and functions as an input unit. As input means, besides the above-mentioned operation switch group, a touch panel mounted on the display surface of the display unit 5 or a remote control switch may be used.

[0034] The position detection unit 2 is, for example, a position detection unit using a GPS (Global Positioning System) receiver, a vehicle speed sensor, an acceleration sensor, an angular velocity sensor, etc., and detects the current position of the mobile body on which the map information processing device is mounted. , and provide the processor 4 with position information representing the detected current position.

[0035] The map inform...

Embodiment approach 2

[0163] Figure 15 It is a block diagram showing the functional configuration of the processor of the map information processing device according to Embodiment 2 of the present invention. exist Figure 15 Among them, the processor 4 in the second embodiment includes a list display unit 14 and a list selection input unit 15 in addition to the functional configuration shown in the first embodiment.

[0164] The list display unit 14 controls the display unit 5 and is a configuration unit that displays a list of object names extracted by the object filtering unit 7 in the character string input by the name input unit 10 .

[0165] The list selection input unit 15 is a component that accepts information input from the input unit 1 , and specifies a name desired by the user from names displayed on the list display unit 14 based on the input information using the input unit 1 .

[0166] Next, the operation will be described.

[0167] In the second embodiment, objects are displayed ...

Embodiment approach 3

[0186] In Embodiment 3, the map information storage unit 3 is provided with head character string information composed of head character string histories corresponding to the second object identifiers in Embodiment 1 and Embodiment 2, so The initial character string history stores an array of character codes for a predetermined number of characters from the initial character of the name representing the second object. That is, in Embodiment 3, the index of the head character string information storing the head character string history of the character string to be represented by the identifier character information is used as the second object identifier in Embodiment 1 and Embodiment 2. character information of the identifier, thereby reducing the data size of the character information of the identifier.

[0187] Figure 19 It is a figure which shows an example of the head character string information in Embodiment 3. exist Figure 19 , the number of characters indicated b...

Abstract

According to the disclosed map information processing device, from among objects to be searched, objects satisfying a predetermined condition of a relationship between the objects are extracted. According to a sequence of characters defined by identifier character information representing a sequence of a predetermined number of characters from the head of a string representing the name of an object, input is prompted for the name of the object, and from among the extracted objects, an object desired by a user is thereby selected.

Description

technical field [0001] The present invention relates to, for example, a map information processing device suitable for use in a navigation device, and particularly relates to a map information processing device with improved operability for inputting names of destinations and the like. Background technique [0002] As a conventional map information processing device, for example, in the device disclosed in Patent Document 1, there is street search data obtained by arranging the names of streets in alphabetical order. When inputting a street name, each time a character is input, the Based on the street retrieval data to display the characters that may be entered next. The user inputs a desired character from among the characters displayed in this way. [0003] That is, when the Nth character (N=1, 2, 3, ...) is input, in order to determine the character that may be input next, all street names registered in the street search data are searched to extract each name The Nth ch...
