The not convenient problem of the query interface when capturing for geography information with device in order to improve GPS commonly used; The present invention proposes a kind of geography information acquisition method; Be applied on the electronic installation that signal is linked to GPS, let the user be able to let the Touch Screen on the electronic installation detect corresponding touch-control indication action with manual manipulation mode intuitively.
See also Fig. 1, it is the process flow diagram that is applied to the geography information acquisition method on the electronic installation proposed by the invention.The flow process of the geography information acquisition method that following first brief description is proposed by the invention is then explained with regard to the details in the core procedure again.
At first; Displayed map information (step S101) then obtains the querying condition that user institute desire is set according to user's operation on the Touch Screen that electronic installation provided, for example refuelling station, dining room or convenience store or the like (step S102) and utilize Touch Screen to detect the touch-control indication (step S103) of user to this electronic installation; After obtaining querying condition that the user sets, touch-control indication that the user has done according to located in connection information, just indicate and geographical data bank is inquired about (step S104) according to these querying conditions and touch-control; Then Query Result is presented in Touch Screen (step S105) afterwards.
Providing operation to obtain among the step S102 of this querying condition according to this user; Electronic installation can utilize the mode of various man-machine interfaces that different input of user or establishing method are provided; For example let the user see through voice mode, handwriting mode comes the input inquiry condition; Or in electronic installation, preset menu is provided to build the mode of putting in advance, using provides the user to select.
In above-mentioned flow process; The topmost conception of the present invention is step S103 and step S104, that is, after utilizing Touch Screen to detect user's touch-control indication; The querying condition that the user that further arranges in pairs or groups sets at step S102 comes geographical data bank is inquired about; Certainly, the sequencing of step S102 and step S103 does not need special qualification, and touch-control indication is chosen on the Touch Screen at least one touch point formed according to the user and chosen scope.
What need explanation is; Among the step S103; The touch-control indication that utilizes Touch Screen to detect the user is meant, when the user arbitrarily carries out arbitrarily intuitive operation with the different operation gesture to Touch Screen, and the scope of choosing that Touch Screen can this operation of sensing be constituted in its surface; After obtaining the touch point information that the scope of choosing contains, see through again software convert into corresponding on the map datum the regional extent Query Information.
Choosing at least one touch point formed on the Touch Screen according to user's intuitive operation, to choose scope can be linear section scope, block block scope or its combination; For example: after letting the user select a plurality of touch points on the Touch Screen arbitrarily, make the formed irregular area of these a plurality of touch points as scope outside the district of bulk etc.Moreover, on Touch Screen, adapt to user's operation and the scope of choosing that forms can see through the user fully and chooses, or by auxiliary the choosing of user of software and form the comparatively complete scope of choosing.
Because core conception of the present invention is to utilize the touch-control indication to use as the nonproductive poll condition; Therefore the variation on other system applies is able to depend on the needs naturally; For example: with regard to the query steps of geographical information; No doubt can utilize the function of building in the electronic installation to come directly to carry out the inquiry of geography information; After can also the information such as the scope of choosing of querying condition and touch-control indication representative being sent to the network system or mobile phone communication system that links with its signal by electronic installation, see through the query steps that server in these systems carries out geography information again.
In other words; Electronic installation can be with building devices such as storage card in the geographical information library in and the function of geographical information query directly is provided; Or seeing through the modes such as network system that link with the electronic installation signal comes the access geographical data bank; And then reach the query function of geography information, as long as can geographical data bank be arranged in pairs or groups in the above-mentioned query steps about the design of touch-control indication step, it is feasible no matter to provide Query Result to be with direct or indirect mode.
See also Fig. 2, it is the inner block schematic diagram of electronic installation with geography information acquisition function provided by the present invention.This electronic installation 10 sees through the GPS 11 of signal binding and the geography information acquisition function is provided, and electronic installation 10 mainly comprises: receiving element 101, signal are linked to GPS 11 and obtain the located in connection information of user position; Touch Screen 103 is electrically connected on receiving element 101, and it shows the cartographic information arround the user position and detects all types of touch-control indication of user for electronic installation 10; And the control module 105 that is connected electrically in Touch Screen 103 is at first obtained querying condition according to this user's operation; Afterwards again according to this querying condition and user to the touch-control indication of Touch Screen 103 and geographical data bank is inquired about, and Query Result is presented on the Touch Screen 103.
The touch-control indication that characteristic of the present invention comes the sensing user to accomplish according to intuitive operation by touch control screen 103; Let touch-control indication correspondence on Touch Screen of user become the formed querying condition of choosing scope and converting correspondence into of at least one touch point; On the other hand; Provide the user to carry out the input of querying condition with the input block 109 that is electrically connected on Touch Screen and control module again; The querying condition here can let the user see through the demonstration of voice mode, handwriting mode input or collocation Touch Screen, provides preset menu in menu, to select relevant querying condition to the user.
Assist the use of geographical data bank by the setting of querying condition and touch-control indicating mode intuitively, mode obtains the geography information capturing result that meets just can to let the user see through more intuitively.Certainly; The step of utilizing geographical data bank to inquire about does not need to limit; That is; No matter be after electronic installation 10 is obtained the querying condition that the user imports, query function directly be provided, or it is feasible to cooperate inquiry to be by the server that signal is linked to electronic installation 10 by electronic installation 10.
In other words, the source being provided and providing the device of query function itself not influence core procedure of the present invention of geographical data bank, so geographical data bank can be provided or provided by electronic installation 10 by the network system (not illustrating) that 10 signals of electronic installation link.When providing by electronic installation 10; Then can arrange in pairs or groups in addition again and use the storage unit 107 that is electrically connected on control module 105; In electronic installation 10, directly provide geographical data bank to give control module 105, let relevant geography information acquisition function can carry out more fast.
Certainly; Viewing system needs and the collocation use this geographical data bank presentation mode of two types with originating arbitrarily; For example in storage unit 107, store user's household or near the geographical data bank the work place; And can provide geographical consulting Query Result to control module 105, in case user's position not when the geographical data bank The corresponding area that prestores, then changes by the provide source of network system (not illustrating) as geographical data bank with fast speeds.
See also Fig. 3 (a) (b) (c), it is that the present invention is with regard to the synoptic diagram of user in the touch-control indication of Touch Screen.Certainly, the explanation here only is to be convenient to explain the preferred embodiment of being lifted, and relevant application and mode of operation all can change and be applied on the electronic installation.
In Fig. 3 (a), suppose the touch-control source that the user detects as operating electronic devices Touch Screen in season 103 with thumb 31 and forefinger 32.Fig. 3 (b) then is that the hypothesis user is the center of circle with the touch point 31a that thumb 31 belongs to; And the user draws camber line I with forefinger 32; Be after the user utilizes thumb 31 and forefinger 32 to choose the first touch point 31a and the second touch point 32a on the Touch Screen 103 earlier; Be that spacing between 2 of the center of circle, the first touch point 31a and the second touch point 32a is a radius and on Touch Screen, choose the camber line scope with the first touch point 31a of thumb 31 representatives again, just can constitute a fan-shaped pattern according to the center of circle of this camber line scope and the first touch point 31a representative.
After in case Touch Screen 103 senses the aforesaid operation of user; Application software in the control module is dynamically emulation and extend the camber line scope just; And then expansion originally fan-shaped pattern and obtain a pie chart appearance; Then this pie chart appearance block scope of representative on Touch Screen just is used as the touch-control indication; In other words, see through Software Operation, the camber line I that the user imported of can continuing together arranges in pairs or groups with another camber line II in inside in addition and completely presents the scope of choosing that a circle is constituted as user's touch-control indication.
Similar; In Fig. 3 (c); The user utilizes thumb 31 to click the first touch point 31b earlier with manual mode; And click the second touch point 32b with forefinger 32; The parameter of the Touch Screen 103 section scope that just can the first touch point 31b and the second touch point 32b be constituted when indication sends control module 105 as inquiry to as touch-control then, control module 105 querying condition that the user sets of just arranging in pairs or groups uses, and inquires about the Query Result that meets in the section scope that is constituted corresponding to these two touch points 31b, 32b on the map datum.
Additional disclosure be; For search function comparatively fast is provided; Electronic installation with geography information acquisition function can be handled cartographic information and the relevant information of searching target respectively usually; That is, the picture of map shown store respectively that the mode by data mapping links map and geography information again with relevant geography information.
Since search target as: the distribution of convenience store or refuelling station etc. is not to set up with the constant spacing mode; Comparatively concentrate or phenomenon such as dispersion comparatively and can form because of the difference of the density of population; For this reason; Relevant data storage mode can also be carried out the optimization process of data structure to the distribution character of searching target, and then reaches the effect of quickening search.The subject under discussion of this respect focuses on the lifting of search speed and relates to core conception nothing of the present invention, only runs over one or two at this.
For instance; The viewing area of Touch Screen can utilize the mesh lines dividing region; Let the user when carrying out the geodata inquiry; At first see through Touch Screen obtain the user when carrying out the touch-control indication related mesh lines zone which is, utilize these mesh lines area relative data directories to carry out the inquiry of geographical data bank afterwards again.
See also Fig. 4 (a)-(e), it is that electronic installation shows and corresponding saving format synoptic diagram with regard to geographical information.Can find out by Fig. 4 (a) and respectively to search the distribution density of target on map and asymmetric; The uneven situation of this kind distribution density will make in the system if adopt the uniform grid line area dividing mode as Fig. 4 (b) shown in, just search target number inequality that maybe each mesh lines zone representative and the possibility that causes wasting the data storing space.In other words; When the mesh lines of collocation Fig. 4 (b) is divided; If store the search target contrast corresponding with it of each mesh lines zone with the table mode of building shown in Fig. 4 (c), the memory headroom of equivalent is no doubt obtained in the lower mesh lines zone of distribution density as far as searching target then because of the relation that internal memory is planned; But do not have corresponding data for storage, and then cause the waste of memory headroom.
For this reason; The improvement practice that the data that the data storing mode of geographical data bank can be correlated with corresponding to the density of map datum obtain; Shown in Fig. 4 (d); Let the cartographic information that Touch Screen 103 showed can be according to its indication range and a plurality of mesh lines zone of not waiting corresponding to area, like mesh lines area 0,1,2 ... 18, because the area in each mesh lines zone is not of uniform size; Therefore just be marked with if only the part of reference numerals is also represented the mesh lines zone; The purpose of dividing these mesh lines zones is that the target collocation geography information of desiring to search is stored after being converted into the comparatively average form of packing density, and these mesh lines area relative are searched target with modes such as data directories, and the geography information that it is corresponding is stored in the geographical data bank.
In other words; When setting up geographical data bank; Geography information can utilize the mesh lines zone that differs in size to come corresponding actual distribution scenario; Therefore, though the region area that mesh lines zone 4 is corresponded to only accounts for 1/64th of region area that the mesh lines area 0 corresponded to, its corresponding search target number (as: number between the refuelling station) is identical; And this also represents the search target distribution in mesh lines zone 4 comparatively intensive, and promptly its distribution density is high far beyond the distribution density in the mesh lines area 0.
Certainly; Might not see through the mesh lines dividing region about appearing of geodata with information such as data structure in the database just can carry out; That is the practices such as the reflection relation of arrangement in the geography information and data content can be quite polynary, and different data search method capable of using quickens the effect of geographical information extraction; This partly relates to the just variation of inquiry application of each system, does not just discuss especially at this and studies carefully.
According to the practice of the present invention; If user's first is in equally when the intersection edge in A district and B district; It is the center of circle that user's first only needs with the self-position; Select as touch point 31a that Fig. 3 (b) is indicated, and with the forefinger collocation and on Touch Screen, form the scope of choosing that a plurality of touch point was constituted, just can learn fuel station information on every side fast.
Can learn by above-mentioned explanation; Be that core develops the electronic installation with geography information acquisition function that after the user is configuring querying condition with the present invention; Just can let the user when watching map with modes such as different gestures or touch-control move as the inquiry of Touch Screen input, and then provide with mode of operation intuitively and let easy in geographical data bank, the capturing of user meet own required geography information.
Though the present invention has disclosed like above-mentioned preferred embodiment, so it is not in order to limiting the present invention, and the present invention must appoint and executes that the craftsman thinks and be to modify right neither taking off as attaching the scope that claims institute desire is protected as all by being familiar with present technique field person.
