Embodiment
In order to make object of the present invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of character input method based on dummy keyboard that the embodiment of the present invention provides, comprises the following steps:
Step S101, respond text unit that current touch-control moved and identified current touch area to input.
Explain word input of the present invention for clear, set forth taking input word as example in full, but word of the present invention is not limited to word.
User, in the time of input word, first touches by the first letter that will input in word on dummy keyboard.Detect user touch the position of pressing, identify touch by locational letter, input as first letter using this letter.In the present embodiment, dummy keyboard is mainly full keyboard layout under English input state.
As shown in Figure 2, user wants to input word word, and the first letter of word is w, for this reason, in dummy keyboard, find alphabetical w key mapping and touch by.
Step S102, taking current touch area as starting point, judge the follow-up line of travel of touch-control action.
User touches and presses first character imperial mother on dummy keyboard according to word, slide position to the second letter place keyboard in word, the present invention judges from first letter to the line of travel of the position of second letter, in the present embodiment, the sliding trajectory that slides generation between two letters is straight line.
As shown in Figure 3, the second letter of word word is o, presses after alphabetical w tactile, slides as rising taking alphabetical w to alphabetical o, and line of travel is now to be slided to the right by alphabetical w.
Text unit input for you to choose on the line of travel of step S103, the action of demonstration touch-control.
The line of travel that is slided generation according to user by first letter to second letter, anticipation goes out the letter that this line of travel will pass through on dummy keyboard.
In the present embodiment, 26 alphabetical distribution situations on pre-recorded dummy keyboard, the namely position on pre-recorded 26 alphabetical place dummy keyboards, identify the straight line that the line of travel taking first letter as starting point produces, the edge of the terminal of default this straight line of the present invention in dummy keyboard, thus can judge this straight line the letter of process.
As shown in Figure 3, alphabetical w slides the letter that will pass through to the right e, r, t, y, u, i, o, p.
Alphabetical e, r, t, y, u, i, o, p are shown, select for user.
Step S103 has further comprised the text unit of input as matching condition, and the text unit on the line of travel of current touch-control action is screened to the step showing.
Obtain the letter that will pass through according to line of travel, the letter that obtains passing through from line of travel, screen, screening rule for: first letter+line of travel obtains the letter that will pass through, or, first letter+line of travel obtains letter+other letter that will pass through, and can be combined into word.The letter that meets screening conditions retains, as the next one letter required with first letter composition word.The letter that does not meet screening conditions is rejected.
If completed the input of multiple letters before, the rule of screening for: obtain the letter that will pass through with multiple letter+line of travel, or first letter+line of travel obtains letter+other letter that will pass through, and can be combined into word.
As shown in Figure 3, alphabetical w slides the letter that will pass through to the right e, r, t, y, u, i, o, p, and letter that wherein can be required with alphabetical w composition word has y, i, o.
Step S103 further comprise by text unit line of travel show on the path of process.
The letter that obtains passing through from line of travel, filter out the next one letter required with first letter composition word, show at line of travel forming the required next one letter of word with first letter.
Step S103 comprises: eject choice box at line of travel;
Choice box is divided into some unit frame;
The text unit filtering out is placed in respectively to each unit frame.
In the present invention, can according to the quantity of the required next one letter of first letter composition word, choice box is divided into the unit frame identical with the quantity of next letter.
In the present embodiment, choice box is circular, is divided into four unit frames.
As shown in Figure 3, letter that can be required with alphabetical w composition word has y, i, o, and alphabetical y, i, o are placed on respectively in a unit frame.
Described method also comprises the slide action detecting in choice box, is specially:
Detect to slide to enter in unit frame, the text unit in selected cell frame is as input;
Detect that the separatrix between unit frame slides and skid off outside choice box, not the text unit in selected cell frame as input.
In the present embodiment, the concrete operations mode in choice box: if will select the letter in choice box, slide to enter and select to be placed in the letter in unit frame in unit frame;
If do not select the letter in choice box, the separatrix between unit frame is slided and is skidded off outside choice box.
In the time that user need to select alphabetical in choice box, slide to enter and in unit frame, can select to be placed in the letter in unit frame.
As shown in Figure 4, in unit frame, there are respectively alphabetical y, i, o, slide and enter the unit frame with alphabetical o, can select the alphabetical o in this unit frame.
Certainly, can also be, slide and enter in unit frame, the time stopping in unit frame could be selected to be placed in the letter in unit frame after reaching Preset Time, and in the present embodiment, Preset Time can be 1～3 second.
In the time that user does not need alphabetical in choice box, the separatrix between unit frame is slided and is skidded off outside choice box, certainly, can also be, arranges one and slide line in choice box, skids off outside choice box along sliding line.
In the present embodiment, four unit frames distribute in choice box, can exist the quantity of the next one letter required with first letter composition word more than four, can not be positioned over the situation in choice box completely, place forming the required next one letter of word with first letter in batches, in choice box, increase following mode of operation:
Upwards slide separatrix along the first half in choice box, switches the next one letter of last consignment of with respect to current state;
Slide downwards separatrix along the latter half in choice box, switches the next one letter of next group with respect to current state.
In the present embodiment, after the text unit in selected cell frame, or the separatrix between unit frame skids off outside choice box, and the content in choice box and frame thereof disappears.
Certainly, can also be, in choice box, one of them unit frame be full keyboard pattern, slides to enter in this unit frame and selects to be placed in the full keyboard pattern in unit frame, and the content in choice box and frame thereof disappears.
In the present embodiment, after the first two letter in input in word, if there is word in input list, unclamp on dummy keyboard touch by, the word of click in input item, completes input; If there is not word in input list, continue to slide to the alphabetical direction lacking in word successively, until word appears in input list.
As shown in Figure 5, after selecting alphabetical o, in input list, also there is not word word, for this reason, also to continue to slide to the alphabetical r of the next one, selecting after alphabetical o, contact rests on alphabetical y place, slided to alphabetical r by alphabetical y, also just slide left taking alphabetical y as starting point, now, the letter that line of travel will pass through is q, w, e, r, t, letter that can be required with the first two alphabetical wo composition word has w, e, r, t, by alphabetical w, e, r, t is placed on respectively unit frame and selects for user, due to four the unit frames that distribute in choice box, one of them unit frame is placed as full keyboard pattern, can be by alphabetical w, e, r, t places in batches, as shown in Figure 6, after selecting alphabetical r, in input list, there is word word, user unclamp touch by, in input list, select word word, complete word input.
