Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Though the present invention is based on the defective of mobile device in the information input process and draws, in fact, the present invention can be applied in the various general or special purpose computingasystem environment or configuration with numeric keypad.For example: computing machine, handheld device or portable set, plate equipment, set top box, programmable consumer-elcetronics devices, comprise distributed computing environment of above any system or equipment or the like.In the description to specific embodiment, mainly be that example describes below with the mobile terminal device.
The present invention can describe in the general context of the computer executable instructions of being carried out by computing machine, for example program module.Usually, program module comprises the routine carrying out particular task or realize particular abstract, program, object, assembly, data structure or the like.Also can in distributed computing environment, put into practice the present invention, in these distributed computing environment, by by communication network connected teleprocessing equipment execute the task.In distributed computing environment, program module can be arranged in the local and remote computer-readable storage medium that comprises memory device.
The present invention is not limited in Rome language or non-Rome language, can use the present invention as long as have the input process of word candidate item.Following specific embodiment only is that example describes with the spell Chinese character input in describing.Words wherein comprises monosyllabic word and multi-character words.
With reference to Fig. 2, show the present invention and utilize numeric keypad to carry out the method embodiment 1 of words input, specifically can may further comprise the steps:
Step 201, reception user pushing to numerical key;
Step 202, be converted to respective coding character string candidate item and show;
Step 201 and 202 is technology that existing mobile terminal device input process is used always, only simply describes at this.The user can comprise pushing to finish the input of Pinyin coding a plurality of numerical keys to pushing of numerical key in the step 201; Wherein, also may comprise the continuous several times of certain numerical key is pushed, for example import certain particular letter in a plurality of basic codings of this numerical key correspondence.
In step 202, according to the difference of specific coding mapping, transformation rule, resulting coded string also may be different, and for example, Pinyin coding, stroke encoding etc. are not described in detail in this.
Need to prove, in step 202, if be converted to have only a coded string, only show that then this coded string gets final product.But in generalized case, pinyin coincident code for example because the number of numeric keypad is less than the quantity of phonetic alphabet, thus when the user by pushing the phenomenon that can have pinyin coincident code when the numerical key input Pinyin is encoded.Can show the coded string candidate item of a plurality of repeated codes that are converted to this moment, selects to make things convenient for the user.
As shown in Figure 3, the user is converted to 4 respective coding character strings " hen ", " gen ", " he " and " ge " by pushing numerical key " 436 " successively.Certainly, in some input method, may only show two coded string candidate item " hen " and " gen ".
Step 203, receive the operational order of user, determine selected coded string candidate item directionkeys; Concrete, when first-selected pinyin candidate item is not that the user takes, as in Fig. 3, the phonetic " gen " that the user needs, rather than preference " hen " then just need direction of passage key (generally being right and left key) to select.
Step 204, user-selected coded string is changed, obtained corresponding word candidate item, show described word candidate item and set the corresponding digital shortcut respectively.That is, when the user in conversion selection course to Pinyin coding, the pairing word candidate item of each Pinyin coding also changes thereupon.
General, because the pairing word candidate item of coded string may be for a plurality of, all show and have difficulties, so, preferably, in step 204, corresponding word candidate item can be divided into multirow, the word candidate item that only shows delegation in user interface makes things convenient for the user to check and selects.As shown in Figure 3, provide pairing 7 word candidate item of first-selected coded string " hen ", after the user has selected phonetic " gen ", then shown " gen " pairing 6 word candidate item.
Further, if in the word candidate item of current line, there is not the user to need, embodiment then shown in Figure 2 can also comprise: receive user's instruction (being generally key up and down), other delegation (as next line or the lastrow) word candidate item under the present encoding character string that definite also explicit user is selected.In fact, observing from user perspective, is exactly the process that a word candidate item page turning shows.
Setting for digital shortcut keys, general, can be according to the ordering of word candidate item, set gradually corresponding digital, referring to Fig. 3, the order according to " gen " pairing 6 word candidate item has set gradually digital shortcut keys 1-6, when the user presses certain key among the numerical key 1-6, just can screen output on its corresponding word candidate item.
Next operational order of step 205, reception user, if the sensing numerical key, then directly will screen output on the pairing word candidate item of this numerical key.
That is, use after the present invention, the user only need trigger button " output of 4-3-6-directionkeys selection-numerical key " successively, just can finish the screen of going up of each word candidate item under the non-first-selected Pinyin coding and export.For example, in Fig. 3, the user triggers button " 4-3-6-right key-numerical key 3 " successively, just word candidate item " gelsemium " can be gone up screen output.With respect to five keystrokes of " the 4-3-6-right key-[OK key]-numerical key 3 " of prior art, the present invention only needs four times, has reduced stroke, thereby can improve user's input efficiency.
And, general, when the user adopts directionkeys to select Pinyin coding, just representing to have finished the input process of Pinyin coding, if so the user after directionkeys operation, next of next-door neighbour is operating as numerical key, illustrates that then the user wishes word selection, and the present invention can satisfy user's mental habit just, and can be very fast will shield on the required words exported; And, though given the numerical key more function, and reduced the intervention of function key, can't influence the input process of the normal Pinyin coding of user.
In a preferred embodiment of the invention, in order to know the selection situation of identifying user to coded string, adopted the technical characterstic that first focus is set on user-selected coded string candidate item, just represented first focus referring to the frame of broken lines 301 of Fig. 3.Described first focus can adopt the mode of underscore, side line, high brightness frame or dash box.
In a preferred embodiment of the invention, when the user carries out the long sentence input by selecting by selected ci poem, to be presented at by speech earlier by the determined word candidate item of numerical key and treat the Shang Ping district, treat that the user has selected last speech after, export each word candidate item one the same screen to the information editing district.This long sentence input process is similar to the long sentence input process of common input method on being applied in personal computer, adopts the numerical key that is adjacent to after the directionkeys to determine word candidate item only in the present invention, so is not described in detail in this.
With reference to Fig. 4, show the present invention and utilize numeric keypad to carry out the method embodiment 2 of words input, specifically can may further comprise the steps:
Next operational order of step 405, reception user, if the sensing numerical key, then directly will screen output on the pairing word candidate item of this numerical key.
If next operational order of user is not a numerical key, then can adopt other variety of way to handle, the present invention does not need to be limited.For example, if the user presses [OK key], then the direction of passage key is selected word candidate item, and then the instruction of the directionkeys of process user gets final product; Perhaps, the user presses cancellation or delete key, then receives instruction to delete certain letter or whole Pinyin coding etc.; Perhaps, the user presses ESC Escape, then receives instruction and closes loading routine etc.
Provided a preferred subsequent step of the present invention below.
Need to prove, in selecting the step 203 of Pinyin coding, the user also second focus can be set, for example, and when the user has selected certain Pinyin coding, can be on this Pinyin coding with first focusing, and with second focal point settings on its corresponding words candidate's preference.
At this moment, if the user chooses required word candidate item, then can pass through function key (as [OK key]) so that screen on the pairing word candidate item of second focus is exported.
But under the situation about having, the user does not find required word candidate item, thinks it may is selected Pinyin coding existing problems, therefore, has carried out subsequent step, reselects Pinyin coding.
Certainly,, in the time of then can working as the user and select this Pinyin coding, can directly found second focus, perhaps, also can work as the user and enter when selecting the word candidate item state, found second focus (similar step 406) again if once do not selected.
Described " this input process " (for example can be understood as whole information editing's process,, the compiling procedure of short message), perhaps, " this input process " also can be understood as the process (for example, the candidate item window once represents) of input of once pronunciation coding and words output etc.
After step 410, if next operational order of user is a numerical key, that then can execution in step 405 finishes word candidate item goes up screen output.
In another preferred embodiment of the present invention, when each switching coded string candidate item (conversion of first focus), described second focus can be positioned on the preference in this word candidate item district all the time; Promptly do not adopt the positional information when record second focus withdraws from the foregoing description.
With reference to Fig. 5, show user's a concrete input example.
At first, the user obtains Pinyin coding " fan ' gan ", " dang " and " fang " by pushing numerical key, and the word candidate item district has showed at the word candidate item of first-selected Pinyin coding " fan ' gan " " dislike, scheme, archives, cake "; But the user finds wherein not its required candidate item, and then the direction of passage key has been selected another Pinyin coding " dang ", and at this moment, the user can be by pushing numerical key, with screen output on the corresponding word candidate item.For example, press numerical key 4, " party " gone up screen output.
If the user has further pushed [OK key] and directionkeys, then can select under the Pinyin coding " dang " required word candidate item.As in Fig. 5, the user selected word candidate item " when ", and in interface synoptic diagram shown in Figure 5, adopt first focus 501 and second focus 502 to identify user-selected Pinyin coding and selected word candidate item.
If finding in the selection course of the word candidate item of user under Pinyin coding " dang " does not also have needed word candidate item, then return, select Pinyin coding " fang " separately.The word candidate item of discovery Pinyin coding " fang " does not have required yet, and then the direction of passage key returns and selects Pinyin coding " dang ".At this moment, because the user is in this input process, once selected Pinyin coding " dang ", thus input method system write down the user return reselect Pinyin coding before, second focus under the Pinyin coding " dang " is at the particular location in word candidate item district.
Therefore, when the user selected Pinyin coding " dang " once more, input method system was directly showed this second focus original position, as, second focus 502 still be positioned at word candidate item " when " on so that the user continues input.Certainly, in another embodiment of the present invention, in the time of also can working as the user and select Pinyin coding " dang " once more, second focus is located immediately on the first-selected word candidate item " archives ".
