Mis-touch recognition method and device
Provided are a mis-operation recognition method and device. In the method, a profile of a touch is determined according to the touch on a touch screen; whether a horizontal coordinate corresponding to a maximum vertical length of the profile is located within a predetermined location range on the touch screen or not is judged; and in a case that it is judged that the horizontal coordinate is located within the predetermined location range, the touch corresponding to the profile is recognized as a mis-touch. By means of the technical solution, a problem caused by a mis-touch generated when a touch screen device is held by a hand is solved, and a mis-operation is prevented, thereby improving user experience.
1. A mis-operation recognition method, comprising:
determining, according to a touch on a touch screen, a profile of the touch;
judging whether a horizontal coordinate corresponding to a maximum vertical length of the profile is located within a predetermined location range on the touch screen or not;
in a case that it is judged that the horizontal coordinate is located within the predetermined location range, recognizing the touch corresponding to the profile as a mis-touch; and
in a case that is judged that the horizontal coordinate is not located within the predetermined location range, further judging whether an area of a graph formed by the profile exceeds a predetermined threshold; in a case that it is judged that the area of the graph formed by the profile exceeds the predetermined threshold, recognizing the touch corresponding to the profile as a mis-touch.
2. The method as claimed in claim 1 , wherein the predetermined location range comprises a horizontal coordinate of points a distance of which to a left edge or right edge of the touch screen is less than or equal to a predetermined value.
3. The method as claimed in claim 2 , wherein
determining the profile of the touch comprises: determining a plurality of coordinates on the profile of the touch;
judging whether the horizontal coordinate corresponding to the maximum vertical length of the profile is located within the predetermined location range on the touch screen or not comprises: judging whether a horizontal coordinate of two points having a largest vertical coordinate difference in the plurality of coordinates is located within the predetermined location range.
4. The method as claimed in claim 1 , wherein the predetermined threshold is determined according to a location of an area on the touch screen.
5. The method as claimed in claim 1 , wherein in a case that there is a plurality of touches, one or more mis-touches in the plurality of touches are recognized separately.
6. The method as claimed in claim 1 , further comprising:
setting the predetermined location range and/or a predetermined threshold according to an input of a user.
7. A mis-operation recognition device, comprising:
a determining component, configured to determine, according to a touch on a touch screen, a profile of the touch;
a first judging component, configured to judge whether a horizontal coordinate corresponding to a maximum vertical length of the profile is located within a predetermined location range on the touch screen or not;
a first recognizing component configured to recognize, in a case that it is judged that the horizontal coordinate is located within the predetermined location range, the touch corresponding to the profile as a mis-touch;
a second judging component configured to further judge, in a case that a judging result of the first judging component is that the horizontal coordinate is not located within the predetermined location range, whether an area of a graph formed by the profile exceeds a predetermined threshold; and
a second recognizing component configured to recognize, in a case that it is judged that the area of the graph formed by the profile exceeds the predetermined threshold, the touch corresponding to the profile as a mis-touch.
8. The device as claimed in claim 7 , further comprising:
a setting component, configured to set the predetermined location range and/or a predetermined threshold according to an input of a user.
9. The method as claimed in claim 2 , wherein in a case that there is a plurality of touches, one or more mis-touches in the plurality of touches are recognized separately.
10. The method as claimed in claim 3 , wherein in a case that there is a plurality of touches, one or more mis-touches in the plurality of touches are recognized separately.
11. The method as claimed in claim 4 , wherein in a case that there is a plurality of touches, one or more mis-touches in the plurality of touches are recognized separately.
12. The method as claimed in claim 2 , further comprising:
setting the predetermined location range and/or a predetermined threshold according to an input of a user.
13. The method as claimed in claim 3 , further comprising:
setting the predetermined location range and/or a predetermined threshold according to an input of a user.
14. The method as claimed in claim 4 , further comprising:
setting the predetermined location range and/or a predetermined threshold according to an input of a user.
15. The device as claimed in claim 7 , further comprising:
a setting component, configured to set the predetermined location range and/or a predetermined threshold according to an input of a user.
16. A mis-operation recognition method, comprising:
determining, according to a touch on a touch screen, a profile of the touch;
judging whether a horizontal coordinate corresponding to a maximum vertical length of the profile is located within a predetermined location range on the touch screen or not, wherein the predetermined location range comprises a horizontal coordinate of points a distance of which to a left edge or a right edge of the touch screen is less than or equal to a predetermined valued; and
in a case that it is judged that the horizontal coordinate is located within the predetermined location range, recognizing the touch corresponding to the profile as a mis-touch;
wherein determining the profile of the touch comprises: determining a plurality of coordinates on the profile of the touch; and judging whether the horizontal coordinate corresponding to the maximum vertical length of the profile is located within the predetermined location range on the touch screen or not comprises: judging whether a horizontal coordinate of two points having a largest vertical coordinate difference in the plurality of coordinates is located within the predetermined location range.
17. The method as claimed in claim 16 , further comprising: in a case that it is judged that the horizontal coordinate is not located within the predetermined location range,
further judging whether an area of a graph formed by the profile exceeds a predetermined threshold;
in a case that is judged that the area of a graph formed by the profile exceeds the predetermined threshold, recognizing the touch corresponding to the profile as a mis-touch.
18. The method as claimed in claim 17 , wherein the predetermined threshold is determined according to a location of an area on the touch screen.
19. The method as claimed in claim 16 , wherein in a case that there is a plurality of touches, one or more mis-touches in the plurality of touches are recognized separately.
20. The method as claimed in claim 16 , further comprising:
setting the predetermined location range and/or a predetermined threshold according to an input of a user.
