By above-mentioned steps, electronic installation can be judged the position that touch screen is pressed from detected m continuous sampling spot.Yet, the present invention comprises that also continuation detects the next sampling spot that is pressed, and get the force value that detects a continuous m sampling spot at last and compare, find out the highest n of a force value sampling spot, and it is the coordinate figure of this n sampling spot is average, obtain the 2nd position that touch screen is pressed, and repetition above-mentioned steps, continue to detect the next sampling spot that is pressed, till can't detecting sampling spot, and obtain the k position at last, wherein k is a positive integer, and then the 1st～k position of above-mentioned acquisition is sent to operating system judges user's touching behavior with the operating system that electronic installation is provided, carry out according to this and choose action.Describe in detail for an embodiment again with next:
Fig. 2 is the be pressed method flow diagram of position of the judgement touch screen that illustrates according to one embodiment of the invention.Please refer to Fig. 2, present embodiment is applicable to the electronic installation with touch screen, and this electronic installation comprises portable electronic devices such as mobile phone, personal digital assistant or notebook computer, and does not limit its scope.Below promptly introduce the detailed step of the method:
At first, in step S210, the coordinate figure and the force value of a plurality of sampling spots that elder generation's detection touch screen is pressed, wherein m is a positive integer.Then, in step S220, after electronic installation receives the coordinate figure and force value of m sampling spot, promptly can compare the force value of this m sampling spot, find out the highest n of a force value sampling spot, wherein n is a positive integer.Then, in step S230, then be that the coordinate figure of this n sampling spot is average, and obtain the position that touch screen is pressed that this position is the 1st position.Above step S210～S230 is all same or similar with the step S110～S130 of previous embodiment, so this repeats no more its detailed content again.
After obtaining this position that is pressed, in step S240, be about to the operating system that this position of calculating gained is sent to electronic installation.And in step S250, electronic installation can judge whether further that then its touch screen can't detect sampling spot.If not, continue to detect the next sampling spot that is pressed, and get the force value that detects a continuous m sampling spot at last and compare, find out the highest n of a force value sampling spot, and it is the coordinate figure of this n sampling spot is average, obtain one the 2nd position that this touch screen is pressed, the 2nd position is sent to the operating system of electronic installation, then repeat above-mentioned steps, till can't detecting sampling spot, and obtain a k position at last, and be sent to the operating system of electronic installation, wherein k is a positive integer.The usefulness of this step is intended to, and user's operational motion is except simple choosing, and the action that also comprises towing is interior, and when carrying out the action of towing, and finger can rest on and continue the touching screen on the touch screen and slide on screen.
In order effectively to detect and judge user's operational motion, when electronic installation finds that touch screen still can detect sampling spot, then get back to step S210, repeated execution of steps S210～S240, to continue the detection sampling spot, to choose the highest sampling spot of force value, and the coordinate figure mean deviation of sampling spot is sent to electronic installation, when treating that touch screen detects less than sampling spot, just enter step S260,, carry out and choose action according to the relativeness between each position that is received by the operating system of electronic installation.
What deserves to be mentioned is that the foregoing description is when whenever detecting a sampling spot, selects the force value of a last m sampling spot to compare immediately, to obtain desired position information.Yet, in another embodiment, electronic installation also can be behind a plurality of sampling spots of continuous detecting, m sampling spot calculates the 1st position before these sampling spots j selects individual to (m+j-1) again, j wherein, m and n are positive integer, and then select that j+1～(m+j) individual k～(m+k-1) individual sampling spot calculates the 2nd position, the k position, so repeat to select and calculate, all be used to calculate with till obtaining last position (p position) and going out positional information up to the coordinate figure of all detected sampling spots and force value, and transmit the operating system of the 1st～p position of calculating gained to this electronic installation, go out pressing position for system's subsequent calculations.Can reach the effect that the present invention improves the accuracy of judging the position that is pressed equally.
In addition, in step S260, when the operating system of electronic installation finds that distance between its 1st of receiving and last p the position is less than a preset value, then can choose and be positioned at these locational objects in its screen, this is the so-called action that clicks merely.On the other hand, when the operating system of electronic installation finds that distance between its 1st of receiving and last p the position is greater than a preset value, then can choose between the object in the scope chosen between these two positions, this is that so-called pull-type is chosen action.Yet above-mentioned two kinds of judgment modes of choosing action are only for illustrating, and are not in order to limiting the scope of the invention, and the operator who knows this area is when visual actual needs, and design is chosen action corresponding to the difference of diverse location relation.
Fig. 3 is the be pressed method synoptic diagram of position of the judgement touch screen that illustrates according to one embodiment of the invention.Wherein, Fig. 3 (a) illustrate is for being presented at a form of touch screen, and hypothetical target 310 persons of being to use want the position that clicks.The user is after pushing touch screen, and touch screen can detect a plurality of sampling spots 320 that illustrated as Fig. 3 (b).These sampling spots 320 are after the method computing of position of being pressed through judgement touch screen of the present invention, and the position that is pressed of delivering to operating system at last then is illustrated in the judged result 330 shown in Fig. 3 (c).Comparison diagram 3 (b) and Fig. 3 (c) use the effectively spreading range of reduced sampling point of method of the present invention as can be known, and increase the accuracy that touch screen is judged the position that is pressed.
With next work effectiveness of lifting example explanation said method again, coordinate figure and force value with reference to the listed sampling spot of table 1, if getting the force value of the 1st～9 sampling spot in front compares, 3 the highest sampling spots of the force value that obtains be the 7th, 8, No. 9 sampling spot, shown in the 1st row of table 2:
| Force value | 1：9616 | 2：6936 | 3：5428 | 4：5201 | 5：4651 | 6：4471 | 7：4203 | 8：4119 | 9：4033 |
| Force value | 2：6936 | 3：5428 | 4：5201 | 5：4651 | 6：4471 | 7：4203 | 8：4119 | 9：4033 | 10：9616 |
Table 2
This moment is average with the coordinate figure of these 3 sampling spots again, can obtain the position that touch screen is pressed:
P1(x，y)＝[(810，3164)+(811，3165)+(810，3162)]/3＝(810，3163)
Then, when detecting the 10th sampling spot, then be that the force value of getting back 9 sampling spots compares, then can obtain 3 the highest sampling spots of force value and be the 8th, 9, No. 10 sampling spot (shown in the 2nd row of table 2), this moment can be average with the coordinate figure of these 3 sampling spots, and obtain the position that touch screen is pressed:
P2(x，y)＝[(811，3165)+(810，3162)+(811，3156)]/3＝(811，3161)
By that analogy, Yi Bian detect sampling spot, calculate the position that is pressed Yi Bian then get last detected 9 sampling spots, till touch screen detects less than sampling spot.Table 3 is classified the position that is pressed of the operating system that is sent to electronic installation as, and wherein, existing method is that to get the coordinate figure of 6 sampling spots average, and method of the present invention then is that the coordinate figure of getting 3 sampling spots that force value is the highest in 9 sampling spots comes average.As shown in Table 3, the coordinate figure scope of existing method extends to 23 pixels in X-direction, extends to 35 pixels on Y direction; Method of the present invention only extends to 3 pixels on X-direction, also only extend to 14 pixels on Y direction, and is obviously accurate than existing methods.
