The device in the embodiment of the invention comprises a user input predicting module, an amplification processing module and a control input module. The embodiment of the invention solves the wrong input problem when the user uses a touch screen miniature entire keyboard without changing the operation habit, and the user can determine a key to be input in a clicking or sliding manner so as to accurately select the key to be input without special operation and to greatly improve the input efficiency of the user while eliminating misoperation of the user.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and apparatus of touch screen user input.
Background technology
Along with growing with each passing day of multimedia information inquiry, people speak of touch-screen more and more, and the user needs only the icon or the literal that bump lightly on the display screen with finger and just can realize host service function, thereby makes man-machine interaction more simple and direct.Touch-screen can be divided into resistance-type, capacitor induction type, infrared-type and surface acoustic wave type touch-screen etc., it is the most a kind of at present man-machine interaction mode, the range of application of touch-screen is very extensive, especially can be used on the electronic equipments such as computer, mobile phone.
The method of touch-screen input at present mainly contains: 1, full keyboard is plotted on the touch-screen, user's finger contacts is behind touch-screen, the single button of touch point correspondence is exaggerated, subsequently, the user can move finger arbitrarily on screen, and the single button of contact point place of arrival amplifies, after the user confirms that the button of current amplification is to need the button of input, finger leaves touch-screen, and selected button corresponding characters is transfused to.2, on touch-screen, be divided into several input lattice, each input lattice is divided middle section, and and middle section plurality of adjacent neighboring area, in each zone definitions of each input on lattice an input character, several input lattice adjoin each other, each input lattice is divided into middle section and reaches zone on the periphery adjacent with middle section, lower area, zone, a left side, right zone, and a side peripheral areas of importing no adjacent input lattice on the lattice is covered by middle section.Click any zone of input lattice and then import the represented symbol of this middle section, enter another one input lattice from an input lattice line, then last input lattice are transfused to by the represented symbol of drawing in that neighboring area.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art:
Though prior art 1 selected single button is exaggerated, owing to blocking of user's finger, selected button is confirmed in user's inconvenience fast; When the user imported, near the button the click on area all was blocked, and when the user clicks mistake, can't determine the particular location at the button place that will import, caused the mistake input easily, caused input efficiency not high.Prior art 2 has redefined the key position of button, and change has taken place operating habit, and one period study laundering period must be arranged before the user uses, and has influenced user's use.
Summary of the invention
Embodiments of the invention provide a kind of method and apparatus of touch screen user input, under the prerequisite that does not change operating habit, have solved the user and have used small-sized full keyboard mistiming input of touch-screen and the not high problem of efficient.
The method of the described a kind of touch screen user input of the embodiment of the invention comprises:
The zone that the user is about to click is predicted;
Prediction result is amplified according to predetermined multiple in predetermined zone;
In magnification region, confirm input.
The device of the described a kind of touch screen user input of the embodiment of the invention comprises:
The user imports prediction module, is used for the zone that the user is about to click is predicted;
The processing and amplifying module is used for that described user is imported the prediction module prediction result and amplifies according to predetermined multiple in predetermined zone;
The control load module is used for confirming input in the zone that described processing and amplifying module is amplified.
The technical scheme that is provided by the embodiment of the invention described above as can be seen, when the user does not click touch-screen, input position to the user is predicted, and amplification estimation range, at this moment the user can confirm the corresponding button of input in magnification region, thereby reached when eliminating user misoperation, do not needed special operation can select the button that to import accurately, improved user's input efficiency greatly.
