Handwriting input shows that relative program 312 comprises: handwriting input detecting element 314, handwriting input character recognition portion 316, and select literal display part 318.The user carries out this image that detects person's handwriting and processes parsing and revisal processing after the handwriting input on the handwriting input zone 306 is detected by handwriting input detecting element 314.Then, handwriting input character recognition portion 316 contrast is stored in the grapholect figure that the Chinese character machine section of grapholect graphic data base 412 is subjected to, person's handwriting after image analysis and the revisal processing is carried out literal identification, when the similar grapholect figure of character and graphic that exists with handwriting input, the Chinese character group that will comprise this similar grapholect figure is presented on the candidate viewing area 308.The character and graphic alternated Chinese character group of user on being presented at candidate viewing area 308 optional its for the moment, select literal display part 318 just should selected character ﹠ graph display on handwriting input zone 306.For example, when the character and graphic of selection is the radicals by which characters are arranged in traditional Chinese dictionaries of any Chinese character, thereby the user just can finish in the part except radicals by which characters are arranged in traditional Chinese dictionaries that is presented at radicals by which characters are arranged in traditional Chinese dictionaries on the handwriting input zone 306 and adds this Chinese character of pen the handwriting input of purpose Chinese character.

The Chinese character candidate shows that relative program 320 comprises: database particular portion 322, Chinese character literal group extraction unit 324, Chinese character scrambling transformation section 326, and Chinese character candidate display part 328.Database particular portion 322 is come specific database as object according to the breathe out pre-process and post-process of literal loading routine 300 of user.Namely, when the user moves to literal input picture from the facility retrieval picture, database as object is exactly facilities information database 404, if move to literal input picture from the destination setting picture, map information database 406 and/or facilities information database 404 just become the database as object, if move to literal input picture from the multimedia operations picture, then multimedia information data storehouse 408 just becomes the database as object.And, for example, in the situation that by selective listing etc. subject area has been carried out moving to literal input picture after the filtering screening during destination setting, only just can realize that the facilities information in this zone carries out the extraction of Chinese character as object.Chinese character information database 402 is extracted in 324 access of Chinese character literal group extraction unit out, the id information of the extraction source database that has in the record according to each Chinese character, and the Chinese character group who only 322 specific databases of above-mentioned database particular portion is associated reads.At this moment, preferably do not read as mentioned above the Chinese character group of the non-feature that is called as termini generales, common noun, perhaps above-mentioned Chinese character group is removed from the Chinese character group who reads, will greatly reduce like this quantity that aftermentioned is presented at alternated Chinese character on the Chinese character candidate display part 328.

The Chinese character group benchmark according to the rules that Chinese character literal group extraction unit 324 is read by Chinese character scrambling transformation section 326 carries out scrambling transformation, is presented on the candidate viewing area 308 by Chinese character candidate display part 328 at a plurality of Chinese characters that will come the front before user's handwriting input.The scrambling transformation of the extraction Chinese character that Chinese character scrambling transformation section 326 carries out is according to the kind of object database or user's selection, carries out based on following a plurality of benchmark.

The 1st scrambling transformation benchmark is to arrange according to what order of total stroke number of Chinese character.The Chinese character that the handwriting input stroke is many bothers very much, and the Chinese character reduction that its literal discrimination also can be few than stroke, so the Chinese character group that stroke number is many is very large as the superiority that candidate shows in advance.The 2nd scrambling transformation benchmark is to arrange according to what order of the stroke number of Chinese character radicals.Owing to extracting the stroke number information of having stored Chinese character radicals in the radicals by which characters are arranged in traditional Chinese dictionaries information database 410 out, therefore can carry out scrambling transformation by reading this information.The 3rd scrambling transformation benchmark is how much arranging according to the input resume of Chinese character.Owing to having the information of the selecteed number of times of this Chinese character in the record of each Chinese character in extracting Chinese character information database 402 out, therefore carrying out scrambling transformation by reading this information.The 4th scrambling transformation benchmark is to arrange according to the new and old order of the update time of the record in the extraction source database of Chinese character.For example, when the Chinese character group who extracts out from facilities information database 404 is carried out permutations according to this benchmark, with reference to the information updating time in the facilities information database of the source database of extracting Chinese character as each out, and according to this update time information carry out scrambling transformation.The 5th scrambling transformation benchmark is according to the user in the record of the former database of extracting Chinese character out the order of the height of the evaluation of content to be arranged.For example, the user minimumly represents with English alphabet A～E respectively from being up to the evaluation information of content in each record in multimedia information data storehouse 408, extracts the scrambling transformation of Chinese character out with reference to the evaluation information in the record in the extraction source of this Chinese character.The 6th scrambling transformation benchmark is to arrange for what the order with resume of the record of the database of extracting the source out according to the user.For example, the information that includes user's play content number of times in each record in multimedia information data storehouse 408; In the facilities information database 121, as its data field, comprise the number of times information that the user accesses each facility data (number of times of for example, each facility being set as the destination, via ground etc.).Therefore this scrambling transformation benchmark carries out scrambling transformation by reading above-mentioned information exactly.The 7th scrambling transformation benchmark be when retrieval to as if with the situation of the relevant facility retrieval that navigates under, according to by centered by the car current location, according to extracting facility by near out to order far away, sequentially carry out the arrangement of with extract facility relevant Chinese character according to this from the facilities information database in the extraction source of extracting Chinese character out.Namely, Chinese character scrambling transformation section 326 is when carrying out scrambling transformation, obtain the current location information of vehicle, the information of the facility position that comprises in the facilities information database with reference to the extraction source of each Chinese character will come the front from the relevant Chinese character of facility close to the current location.

The Chinese character group that Chinese character candidate display part 328 is extracted Chinese character literal group extraction unit 324 out behind Chinese character scrambling transformation section 326 scrambling transformations, arranges shape with its transverse and longitudinal and configures and be presented on the candidate viewing area 308.If the user operates page-turning button, on candidate viewing area 308, will switch the Chinese character group who shows time candidate.The user can select each Chinese character that shows by touch operation or button operation, selecteed Chinese character is displayed on when determining literal viewing area 304, and the ensemble that comprises this Chinese character will be extracted out from database and be presented on the candidate viewing area 308.

The information candidate shows that relative program 330 comprises selection information extraction unit 332 and information candidate display part 334.When the user has selected a Chinese character from the aforesaid Chinese character group who is presented on the candidate viewing area 308, select information extraction unit 332 just to go the access object database to obtain the information that comprises this Chinese character.Recorded the ID of the source database of extracting this Chinese character out in the record of each Chinese character of storage Chinese character group's extraction Chinese character information database 402, system is according to this information special object database.For example, if selected Chinese character is the words of extracting out from the information of facilities information database, owing to having recorded the identification id of facilities information database in the record of this Chinese character, therefore select information extraction unit 332 just according to this message reference facilities information database 404, extract one or more facilities information that comprises this Chinese character out.The ensemble tabulation that information candidate display part 334 will be extracted out like this is presented on the candidate viewing area 308.That is, this moment demonstration of candidate viewing area 308 is arranged by Chinese character group's transverse and longitudinal and is shown that the tabulation that switches to ensemble shows.Putting in order when in addition, ensemble shows also can be carried out according to above-mentioned Chinese character group's scrambling transformation benchmark.That is, can arrange as benchmark with the evaluation that utilizes resume, final updated time, user of information, the positional information take vehicle as benchmark etc.For the various candidate information of reality, the user can select by touch operation or button operation, and selected Chinese character will be displayed on to be determined on the literal viewing area 304.

The user operates relative program 336 and comprises literal selection instruction unit 338 and select literal detecting element 340.Literal selection instruction unit 338 control displays can be selected by the user at each regional literal of input picture.As previously mentioned, the 308 Chinese character groups that show, ensemble, character and graphic can be selected by the operation of the selections such as cursor movement on touch operation or the picture in the candidate viewing area.In one embodiment, determining that literal viewing area 304 shown literal groups also can select instruction unit 338 to select by literal, operate the operation that can carry out the cancellation object character, show information candidate group based on this literal by this selection.The literal that shows on candidate viewing area 308 or the definite literal viewing area 304, when information is selected by the user, selects literal detecting element 340 to detect this selections and operate.According to this selection operation that detects, selecteed Chinese character, literal just are determined as input characters, as previously mentioned, select information extraction unit 332 to begin to carry out the processing such as information extraction.

Secondly, according to the process flow diagram of Fig. 5～Fig. 7 and with reference to the concrete processing procedure of the picture transition graph comment loading routine of Fig. 8 (A)～Fig. 8 (C), Fig. 9 (A)～(C).Below, the specific facilities when navigating relevant destination setting with the user is retrieved as example and describes.The user has selected " destination setting " at the picture of the comprehensive menu of not shown electronic apparatus for mounting on vehicle after, will show that the destination shown in Fig. 8 (A) arranges picture 800.When the user arranged picture 800 and selects " destination title " in this destination, when picture moved to the literal input picture 802 shown in the figure (B), system side detected this selections and operates and begin to carry out this processing (step S502: be).At first, come special object database (step S504) according to the context of user's selection.Here, user's selection is that the destination arranges, and goes on record so facilities information database and map information database just are used as object database.

On the picture of Fig. 8 (B), the user for the subject area to the destination is filtered, screening and touch operation during operation push-button 810, just show as the zone shown in the figure (C) and select picture 803.The name list in administrative area is selected to demonstrate with the English alphabet sortord on the picture 803 in the zone.On Fig. 8 (C), the zone selects the right of picture 803 to show a plurality of selection keys, is assigned with respectively on these a plurality of selection keys and is provided with a plurality of English alphabets.When if the user has selected a selection key, the letter that is assigned with on this button respectively is displayed on the left side of picture as the tabulation of province's name of first letter of pinyin.For example, if the user has selected with the button of " JKL " at Fig. 8 (C), then phonetic beginning letter be respectively " J ", " K ", " L " province title " Jilin Province ", " Jiangsu Province ", " Jiangxi Province ", " Liaoning Province " just as shown in the figure tabulation be presented at the left part of picture.If this moment, the user selected " Liaoning Province " by touch operation from tabulation, picture will move to the display frame shown in Fig. 9 (A), can tabulate here to show the city title that is under the jurisdiction of Liaoning Province.Simultaneously the right side of the display frame of Fig. 9 (A) has also shown with the zone of Fig. 8 (C) and has selected the identical button of picture 803, if selected wherein 1 button this moment, the English alphabet that is arranged on this button take distribution respectively will show in the left side of picture as the city title of first letter of pinyin (having selected the title in the city under the province (Liaoning Province)) in selectable tabulation.By layer by layer filtration, screening to the zone, the user can dwindle the zone under the destination of retrieving like this, thereby will be so that it selects the quantity of candidate relatively to reduce.

If the user has selected specific city (being " Daliang City " in this example) at Fig. 9 (A), will be as again switching to literal input picture 802 shown in the figure (B).At this moment, the Chinese character group who extracts out from specific data with total stroke number from how to be presented on the candidate viewing area 804 to few order.That is, when the user has selected specific city from city list, shown in the process flow diagram of Fig. 5, be judged as and require to carry out literal input processing (step S506: be).Then, system access is extracted Chinese character information database 402 out, reads from the Chinese character group (step S508) of facilities information database and map information database extraction.In the preference, the Chinese character group of the Chinese character group who reads here for limiting by user's selected areas (being " Daliang City " in this example).Then, display text input picture 802 (step S510), further, with the Chinese character group that extracts out according to total stroke number from how to carrying out less scrambling transformation, shown in Fig. 9 (B), be presented at (step S512) on the candidate viewing area 804.

Move to Fig. 6, judge that in system under the state of Fig. 6 whether the user is from having selected alternated Chinese character (step S514) by step S512 among the alternated Chinese character groups that candidate viewing area 804 shows.Here, if judge system judges whether the user has carried out handwriting input operation (step S516) to hand-written input area 806 when the user does not carry out the selection operation of alternated Chinese character (step S514: no).If detected the handwriting input (step S516: be) from the user, literal identifying processing (step S518) is carried out in this input, identify successfully and determine that according to user's input operation has realized in the situation of selection operation of Chinese character (step S520: be) at literal, when perhaps in above-mentioned steps S514, detecting the user and having selected a alternated Chinese character among the alternated Chinese character group (step S514: be), Chinese character selected by the user is inputted definite (step S521) as input characters.Afterwards, starting selection information extraction unit 332 (Fig. 3) extract the ensemble (step S522) that comprises this Chinese character out from object database, are presented at (step S524) on the candidate viewing area 804.On the other hand, successfully carry out if in step S520, fail literal identification or literal identify successfully after the user do not carry out in the situation that the selection of Chinese character operates (step S520: no), ignore this input or will fail successfully to carry out the meaning that literal identifies and notify to the user (step S523).After the processing execution of this step S523, when perhaps not detecting the handwriting input from the user in above-mentioned steps S516, system returns step S514 and waits for input operation from the user.Fig. 9 (B) represents to have selected " prosperous " from the Chinese character group that candidate viewing area 804 shows, the result comprises the facility title of this selection Chinese character and the 804 tabulation demonstrations in the candidate viewing area as shown in the figure (C) from the extraction of facilities information database.This selects Chinese character after the selected operation of Fig. 9 (B), is also shown in shown in Fig. 9 (C) and determines on the literal viewing area 808.

Move to Fig. 7, system wait is from user's input (step S526) under state shown in Figure 7.Here, if the user on handwriting input zone 806 addition inputs literal (step S526: be), literal identifying processing (step S528) is carried out in this input, if literal is identified successfully and determine that according to user's input operation has realized that Chinese character selected by the user is transfused to definite (step S531) as the addition inputs literal in the situation of selection operation of Chinese character (step S530: be).Afterwards, carry out the processing of step S532, to filtering retrieval by the above-mentioned steps S524 candidate ensemble that 804 tabulations show in the candidate viewing area.That is, extraction comprises the Chinese character of being determined by step S521 input and the information that is added the Chinese character of input simultaneously from object database.Afterwards, process turning back to step S524, will be by the 804 tabulation demonstrations in the candidate viewing area of one or more candidate information after the step S532 filtration retrieval.On the other hand, successfully carry out if in step S530, fail literal identification or literal identify successfully after the user do not carry out in the situation that the selection of Chinese character operates (step S530: no), ignore this input or will fail successfully to carry out the meaning that literal identifies and notify to the user (step S534).

If in step S526, the user does not append the input of literal, but from the information (such as the facility title of Fig. 9 (C)) that candidate viewing area 804 shows, chosen one (step S536: no) wantonly, this information is determined (step S538) as the information of user's input, finish the processing of this literal loading routine.Afterwards, this facility title that is determined is delivered to the destination setting program, carry out the setting of destination etc.

Below, the 2nd embodiment of the present invention is described.When display text is inputted picture in the above-described embodiment, before user's input, just demonstrate the Chinese character group who from information database, extracts out in the candidate viewing area.According to the literal loading routine of present embodiment, what show at first during display text input picture is the Chinese character group's that extracts out from information database radicals by which characters are arranged in traditional Chinese dictionaries.Figure 10 is the block diagram of the formation of expression literal loading routine.To give identical symbol with the common part of the block diagram of the 1st embodiment shown in Figure 3 among Figure 10, the function of this common part is illustrated in above-mentioned the 1st embodiment, repeats no more here.

Literal loading routine 1000 except have above-mentioned handwriting input show relative program 312, Chinese character candidate show relative program 320, information candidate show relative program 330, and the user operate the relative program 336, the candidate that also has radicals by which characters are arranged in traditional Chinese dictionaries shows relative program 342.

The candidate of radicals by which characters are arranged in traditional Chinese dictionaries shows that relative program 342 comprises Chinese character radicals group extraction unit 344, radicals by which characters are arranged in traditional Chinese dictionaries scrambling transformation section 346, reaches radicals by which characters are arranged in traditional Chinese dictionaries candidate display part 348.Radicals by which characters are arranged in traditional Chinese dictionaries information databases 410 are extracted in Chinese character radicals group extraction unit 344 access out, only read from the radicals by which characters are arranged in traditional Chinese dictionaries of the Chinese character group extraction that comprises with above-mentioned database particular portion 322 specific databases.The id information of the extraction source database that the record of this Chinese character comprises in the id information of the extraction source Chinese character that each radicals by which characters are arranged in traditional Chinese dictionaries of Chinese character radicals group extraction unit 344 reference extraction radicals by which characters are arranged in traditional Chinese dictionaries information databases 410 have and the extraction Chinese character information database 402 carries out this extraction and processes.

The radicals by which characters are arranged in traditional Chinese dictionaries group that Chinese character radicals group extraction unit 344 is read carries out scrambling transformation by radicals by which characters are arranged in traditional Chinese dictionaries scrambling transformation section 346 according to what order of stroke number, and a plurality of radicals by which characters are arranged in traditional Chinese dictionaries that come the front are being presented on the candidate viewing area 308 before user's handwriting input by radicals by which characters are arranged in traditional Chinese dictionaries candidate display part 348.The extraction radicals by which characters are arranged in traditional Chinese dictionaries scrambling transformation that radicals by which characters are arranged in traditional Chinese dictionaries scrambling transformation section 346 carries out can be according to the kind of object database, user's selection, and the full scrambling transformation benchmark of Chinese character of following the 1st embodiment carries out scrambling transformation.For example, also can the person of consulting and using select frequency sequence, become what the order, further of total stroke number that the Chinese character in source extracted out in radicals by which characters are arranged in traditional Chinese dictionaries, become and carry out the usage frequency of information in extraction source of this Chinese character or update time etc. scrambling transformation.

Radicals by which characters are arranged in traditional Chinese dictionaries group behind the radicals by which characters are arranged in traditional Chinese dictionaries scrambling transformation section that passes through 346 scrambling transformations that radicals by which characters are arranged in traditional Chinese dictionaries candidate display part 348 is extracted Chinese character radicals extraction unit 344 out is and arranges in length and breadth shape and be configured on the candidate viewing area 308.When the user had operated page-turning button, 308 switched the radicals by which characters are arranged in traditional Chinese dictionaries group who shows time candidate in the candidate viewing area.The user can select each the radicals by which characters are arranged in traditional Chinese dictionaries candidate that shows according to touch operation or button operation, and extraction from database comprises the Chinese character group of these radicals by which characters are arranged in traditional Chinese dictionaries and is presented on the candidate viewing area 308 according to this selection operation Chinese character literal group extraction unit 324.Meanwhile, selected radicals by which characters are arranged in traditional Chinese dictionaries are presented on the handwriting input zone 306, and the user can carry out to it input operation of adding of part beyond the radicals by which characters are arranged in traditional Chinese dictionaries of this Chinese character.Processing afterwards is identical with the 1st embodiment, and according to the specific Chinese character that the user selects from the Chinese character group that candidate viewing area 308 shows, the information list switching that will comprise this Chinese character shows.

Secondly, according to the process flow diagram of Figure 11, Figure 12 and with reference to the concrete processing procedure of the picture transition graph comment loading routine of Figure 13 (A)～Figure 13 (C), Figure 14.Below, omit the explanation with the processing phase repeating part of the 1st embodiment.After the user had selected " destination setting " at the comprehensive menu screen of not shown electronic apparatus for mounting on vehicle, the destination that picture just moves to the electronic apparatus for mounting on vehicle shown in Figure 13 (A) arranged on the picture 1200.Arrange on the picture 1200 in this destination, when the user selected " destination title ", system side detected this selection operation and begins to carry out this processing (step S1102: be).At first, come special object database (step S1104) according to the context of user's selection.Here, user's selection is " destination setting ", goes on record so facilities information database and map information database just are used as object database.

Then, the user filters for the subject area to the destination, by with above-mentioned the 1st embodiment in identical Fig. 8 (B), the operation shown in Fig. 8 (C), the user is selecting " Liaoning Province ", then from as having selected " Daliang City " afterwards the city name list shown in Figure 13 (B) of the result of above-mentioned selection, will switch to as the input of literal shown in the figure (C) picture 1302.

The radicals by which characters are arranged in traditional Chinese dictionaries group of the Chinese character of at this moment, extracting out from specific data with the radical and stroke number from how to be presented on the candidate viewing area 1304 to few order.That is, when the user has selected specific city from the name list of city, shown in the process flow diagram of Figure 11, be judged as and require to carry out literal input processing (step S1106: be).Then, system access is extracted radicals by which characters are arranged in traditional Chinese dictionaries information database 410 out, reads radicals by which characters are arranged in traditional Chinese dictionaries group (step S1108).Here, the Chinese character group's who only extracts out take specific database (facilities information database and map information database) from previous processed radicals by which characters are arranged in traditional Chinese dictionaries are as object, the radicals by which characters are arranged in traditional Chinese dictionaries group who reads.As preference, the radicals by which characters are arranged in traditional Chinese dictionaries group energy of reading here enough only is limited to zone (being " Daliang City " in this example) facilities information that comprises of user's selection and the Chinese character group's of cartographic information radicals by which characters are arranged in traditional Chinese dictionaries.Then, display text input picture 1302 (step S1110), further, with the radicals by which characters are arranged in traditional Chinese dictionaries group that extracts out according to stroke number from how to carrying out less scrambling transformation, shown in Figure 13 (C), be presented at (step S1112) on the candidate viewing area 1304.

Move to Figure 12, judge that in system under the state of Figure 12 whether the user is from having selected candidate radicals by which characters are arranged in traditional Chinese dictionaries (step S1114) by step S1112 among the alternated Chinese character radicals by which characters are arranged in traditional Chinese dictionaries groups that candidate viewing area 1304 shows.Here, if judge system judges whether the user has carried out handwriting input operation (step S1116) to hand-written input area 1306 when the user does not carry out the selection operation of candidate radicals by which characters are arranged in traditional Chinese dictionaries (step S1114: no).If detected the handwriting input (step S1116: be) from the user, literal (radicals by which characters are arranged in traditional Chinese dictionaries) identifying processing (step S1118) is carried out in this input, identify successfully and determine that according to user's input operation has realized in the situation of selection operation of radicals by which characters are arranged in traditional Chinese dictionaries (step S1120: be) at literal (radicals by which characters are arranged in traditional Chinese dictionaries), when perhaps in above-mentioned steps S1114, detecting the user and having selected candidate radicals by which characters are arranged in traditional Chinese dictionaries among the alternated Chinese character radicals by which characters are arranged in traditional Chinese dictionaries group (step S1114: be), starting Chinese character literal group extraction unit 324 (Fig. 3), extract the Chinese character group (step S1122) comprise these selection radicals by which characters are arranged in traditional Chinese dictionaries from object database out, be presented at (step S1126) on the candidate viewing area 1304 with total stroke number of Chinese character from the few order of as many as.On the other hand, successfully carry out if in step S1120, fail literal (radicals by which characters are arranged in traditional Chinese dictionaries) identification or literal (radicals by which characters are arranged in traditional Chinese dictionaries) identify successfully after the user do not carry out in the situation that the selection of radicals by which characters are arranged in traditional Chinese dictionaries operates (step S1120: no), ignore this input or will fail successfully to carry out the meaning that literal identifies and notify to the user (step S 1124).After the processing execution of this step S1124, when perhaps not detecting the handwriting input from the user in above-mentioned steps S1116, system returns step S1114 and waits for input operation from the user.Figure 13 (C) expression has been selected radicals by which characters are arranged in traditional Chinese dictionaries " rice " from the radicals by which characters are arranged in traditional Chinese dictionaries group that candidate viewing area 1304 shows, the result as shown in figure 14, extract the Chinese character that comprises these radicals by which characters are arranged in traditional Chinese dictionaries out from extracting the Chinese character information database out, be presented on the candidate viewing area 1304 with the form of arranging in length and breadth.Simultaneously, these radicals by which characters are arranged in traditional Chinese dictionaries are also shown on the handwriting input zone 1306, and the user also can add the radicals by which characters are arranged in traditional Chinese dictionaries part in addition of pen input Chinese character, thereby carries out the screening of purpose Chinese character.

Processing shown in Fig. 6 of same the 1st embodiment of later processing and Fig. 7, Fig. 9 (B), Fig. 9 (C) is identical.Namely, in the display frame of Figure 14, the user is by optional one the Chinese character group on being presented at candidate viewing area 1304 or by inputting in handwriting input zone 1306, thereby specific go out the purpose Chinese character after, system extracts out and shows the tabulation that comprises the facility title of this Chinese character in the database, selects for the user.The detailed content of the processing of this common part please refer to the explanation to the 1st embodiment.

As other embodiments of the present invention, if when one of an individualism comprises the database of information of a plurality of Chinese character literal in Fig. 3 and database 400 shown in Figure 10 (for example only existing in the situation of facilities information DB404), perhaps, in a plurality of databases, in the situation about being set in advance as the object database of extracting Chinese character literal group or Chinese character radicals group out, in Fig. 5, process flow diagram shown in Figure 11, the processing of step S504, the step S1104 of specific extraction Chinese character literal group or Chinese character radicals group's object database just can be omitted.
