The selection that need to prove all functions item in the present embodiment is all finished by finger striking correlation function option with use, such as the interface of opening short message input character function.Described touch-control body can also be the heatable touch-control body of contact except pointing, such as the pointer of nib heating.

Fig. 2 is the schematic flow diagram that the mobile communication terminal of the embodiment of the invention two uses the method for touch-screen input character.As shown in Figure 2, comprise following:

Step S201, detect the heat energy information of described touch-control body contact.

Herein, the user is moved to striking screen top position with touch-control body contact in the situation that does not contact touch-screen, and the highly sensitive body heat sensor on the touch-screen just can be responded to the heat energy on the touch-control body contact.For example, when the touch-control body was finger, the highly sensitive body heat sensor on the touch-screen just can be sensed the heat energy on the finger finger, detected the heat energy information of this heat energy.

Step S202, according to detected heat energy information, judge that heat energy value in the described heat energy information is whether in the scope of preset value; If judged result is not in the scope of preset value, then be transferred to step S204; If judged result is in the scope of preset value, then be transferred to step S203.Described preset value is meant the standard gate limit value that the heat energy to sensing that sets in advance in the mobile communication terminal is judged.Because highly sensitive energy sensor can both be responded to all extraneous heat energy all the time, these heat energy major parts come from surrounding environment, so in order effectively to get rid of these extraneous disturbing factors, characteristic at the highly sensitive body heat sensor of difference, judge suitable heat energy value by setting in advance a threshold value, thereby determine that described heat energy source is in the contact of touch-control body.For example,, judge whether the heat energy value in this heat energy information is higher than the value that sets in advance,, illustrate that pointing finger can operate touch-screen if be higher than preset value according to the heat energy information of sensing the finger finger.

Step S203, obtain on the described touch-screen position coordinates of the heat energy value maximum that obtains from described contact.

Herein, in case the heat energy value satisfies the threshold value that sets in advance, mobile communication terminal will obtain on the described touch-screen position coordinates of the maximum heat energy value that obtains from described contact, i.e. the more nearest position coordinates that distance should described contact maximum heat energy value on the touch-screen.

Step S204, do not obtain on the described touch-screen position coordinates of the heat energy value maximum that obtains from described contact.

Again obtain the heat energy information of touch-control body contact herein, satisfy the requirement of predefined threshold value up to the energy that obtains described contact.

Step S205, according to the position coordinates that step S203 gets access to, obtain the range information between described position coordinates and character or the button.

, determined contact behind the position coordinates on the touch-screen herein, mobile communication terminal just can calculate the coordinate of different characters or button correspondence and the range information between described position coordinates.

Step S206, according to this range information, judge whether the distance value in the described range information meets the demands; Be whether described distance value is in the scope of the value of setting in advance.If do not meet the demands, then be transferred to step S207; If meet the demands, then be transferred to step S208; Herein, described distance value is meant the distance values between the corresponding coordinate of each character on described contact position coordinate and the touch-screen or button, as long as it is to wish button or the character that is presented on the soft keyboard carried out input operation that this numerical value in the numerical range that sets in advance, just illustrates described contact.

Distance value in step S207, the described range information then obtains the position coordinates of touch-control body contact again not in the numerical range that sets in advance.

Herein, mobile communication terminal judging distance value is not in the numerical range that sets in advance, illustrate that this moment, described contact also had with a certain distance from nearest character or button, though the soft keyboard of opened input character, but contact may be in other positions of touch-screen, not in inputting interface, this moment, the user may be in no hurry to input character, so at this moment mobile communication terminal is not carried out satisfied step.

Distance value in step S208, the described range information is in the numerical range that sets in advance, and mobile communication terminal then obtains and the nearest character of described contact or the coordinate of button.

Herein, when in the numerical range that described distance value is setting in advance, illustrate that described contact wishes the character or the button that show on the touch-screen are carried out input operation, at this moment mobile communication terminal obtains character or the button corresponding coordinate nearest with described contact according to distance value.

Step S209, basis character or coordinate amplification demonstration described character or the button of button, perhaps adjacent coordinates corresponding characters simultaneously amplification demonstration described character respective coordinates on or the adjacent coordinates corresponding key described button respective coordinates on nearest with described contact.

Herein, after mobile communication terminal has obtained the coordinate corresponding with nearest character of described contact or button, just corresponding character of this coordinate of demonstration or button be can amplify, the adjacent coordinates corresponding characters of the described character respective coordinates of demonstration or the adjacent coordinates corresponding key on the described button respective coordinates perhaps amplified simultaneously.The user just can more select to amplify the character or the button of demonstration like this.

Step S210, user's striking amplify character or the button that shows, import described character or carry out the function of described button.

Herein, the user is according to amplifying character or the button that shows, striking target character or target button, mobile communication terminal detect and handle the striking signal on described target character or the target button, thereby show by the character of striking or button in the zone of the character that the demonstration that sets in advance is imported.When character display or button are amplified in striking, can be changed color by the character of striking or button, thereby the user more can clearly be confirmed by the character of striking or button.

In embodiments of the present invention, for mobile communication terminal, carry out example with mobile phone.According to the method for above-mentioned mobile communication terminal use touch-screen input character, for the project of the input character in the mobile phone, the action that the user finishes the input Chinese character with finger is exemplified below:

To import " hello " two Chinese characters with the Chinese phonetic alphabet in the SMS (short message service) function is example, when the user opens the message function interface, handset touch panel demonstrates the soft keyboard zone of waiting to import Chinese character, the soft keyboard of supposing described demonstration is the standard computor-keyboard, then each alphabetical corresponding key in the display standard computor-keyboard on the keyboard area.The user moves to described keyboard area top position with finger, and so-called keyboard area top position refers to that promptly the touch-screen top does not contact the zone of touch-screen.Because finger has moved to the touch-screen top position, mobile phone detects the heat energy information on the finger finger, judge that heat energy value in the described heat energy information is whether in the threshold value scope, the result is not in threshold value, illustrate that this moment, finger also had with a certain distance from touch-screen, continue to obtain the heat energy information of finger finger.Because the Chinese phonetic alphabet structure of " hello " is " nihao ", so the user will point the button that indicates letter " n " that shows near to described keyboard gradually earlier according to Pinyin rule, heat energy value in the heat energy information on the mobile phone judgement finger finger is in predefined threshold value scope, illustrate that this moment, the user wished to carry out the operation of input character with finger, thus the position mobile phone near button " n " obtain on the touch-screen with the finger finger on nearest any the position coordinates of maximum heat energy value.According to described position coordinates, mobile phone calculates the coordinate of different button correspondences and the range information between this position coordinates.Judge and select in these range informations distance value which in the scope that sets in advance, mobile phone obtains the button coordinate that indicate letter " n " and " m " nearest with the finger finger (the button coordinate that at this moment alphabetical " n " and " m " be described is identical from the distance of pointing finger) according to the distance value that meets the demands in this range information again.Mobile phone just amplifies the button that demonstration indicates letter " n " and " m " on touch-screen subsequently.After the user sees the letter " n " and " m " that amplifies demonstration on the screen, the letter " n " that shows is amplified in striking, mobile phone detects the striking signal on the coordinate that amplifies the letter " n " that shows, handle described striking signal, mobile phone just shows the letter " n " that is transfused in the zone of record input character, after the input of finishing described letter " n ", finger leaves touch-screen, and this moment, mobile phone detected the position at the finger of striking screen upper area again.The user will point finger again near on the button that indicates letter " i " that shows to described keyboard, mobile phone is judged the heat energy value of the heat energy information in the finger finger in predefined threshold value scope, illustrate that this moment, the user wished to carry out the operation of input character with finger, so mobile phone obtains on the touch-screen near nearest any the position coordinates of the position of button " i " and the maximum heat energy value on the finger finger.According to described position coordinates, mobile phone calculates the coordinate of different button correspondences and the range information between this position coordinates.Because the distance value of described range information middle distance button " i " coordinate is in the scope that sets in advance and be the nearest button in distance finger finger position, mobile phone just amplifies on touch-screen and shows the button that indicates letter " i ".After the user sees the letter " i " that amplifies demonstration on the screen, the letter " i " that shows is amplified in striking, mobile phone detects the striking signal on the coordinate that amplifies the letter " i " that shows, handle described striking signal, mobile phone shows in the zone of record input character that just " i; after the input of finishing described letter " i " points and leaves touch-screen the letter that is transfused to, and this moment, mobile phone detected the positional information at the finger of striking screen upper area again.Mobile phone is arranged out the Chinese character that pronunciation requires that meets that comprises Chinese character " you " according to the zone " n " of input character and the combination of " i " simultaneously.Finger is near to the Chinese character " you " that shows, mobile phone judges that heat energy value in the heat energy information in the detected finger finger is in the threshold value scope that sets in advance, illustrate that this moment, the user wished to carry out the operation of input character with finger, thus the position mobile phone near Chinese character " you " obtain on the touch-screen with the finger finger on nearest any the position coordinates of maximum heat energy value.According to described position coordinates, mobile phone calculates the coordinate of the identical Chinese character correspondence of the pronunciation of demonstration and the range information between this position coordinates.Judge and select in these range informations distance value which in the scope of the value of setting in advance, mobile phone obtains and the nearest Chinese character " you " of finger finger and " Buddhist nun's " coordinate (illustrating that the coordinate of Chinese character " you " and " Buddhist nun " is identical from the distance of pointing finger at this moment) according to the distance value that meets the demands in this range information again.Mobile phone just amplifies demonstration Chinese character " you " and " Buddhist nun " on touch-screen subsequently.After the user sees the Chinese character " you " and " Buddhist nun " that amplifies demonstration on the screen, the Chinese character " you " that shows is amplified in striking, mobile phone detects the striking signal on the coordinate that amplifies the Chinese character " you " that shows, handle described striking signal, mobile phone just shows the Chinese character " you " that is transfused in the zone of record input character, after the input of finishing described Chinese character " you ", finger leaves touch-screen, and this moment, mobile phone detected the positional information at the finger of striking screen upper area again.The input of Chinese character " good " and the input of Chinese character " you " are similar, and only the letter of corresponding input is different, so no longer be repeated in this description.

Amplify in the time of also can be in the present embodiment and show other buttons adjacent with this button according to the button that amplify to show, amplify demonstration other buttons adjacent in the time of such as display button " i ", such as button " u ", button " j ", button " k ", button " o " with button " i ".And, when selecting the Chinese character input, amplify demonstration other Chinese characters adjacent simultaneously according to amplifying the Chinese character that shows, also amplify demonstration other Chinese characters adjacent when going out Chinese character " you ", as Chinese characters such as " mud ", " plans " with Chinese character " you " such as screen displaying with this Chinese character.And in striking target button or character, can be changed by the button of striking or character color such as " i " or " you ", the user can know button or the Chinese character of seeing around this button or the Chinese character coordinate other like this, also can clearly identify the button or the Chinese character of institute's striking, be very beneficial for the user at every turn striking quick and precisely want button or the Chinese character imported.

The embodiment of the invention is under the situation of not striking of finger body touch-screen, by obtaining on the touch-screen and the nearest position coordinates of touch-control body contact that is positioned at described touch-screen upper area, determine and the nearest character of described position coordinates or the coordinate of button, determine to need to amplify character or the button that shows by the coordinate of described character, the user finishes striking again according to amplifying the character or the button that show in advance, make the user at every turn accurately on the striking touch-screen initial show than small characters or button, particularly made things convenient for some the elderlys to use mobile phone input Chinese character.

The selection that need to prove all functions item in the present embodiment is all finished by finger striking correlation function option with use, such as the interface of opening short message input character function.Described touch-control body can also be the heatable touch-control body of contact except pointing, such as the pointer of nib heating.
