Method and device for implementing click and location operations on touch screen
View Patent ↗A method for implementing click and location operations on a touch screen is disclosed. The method includes: a position relation between a touch point and a target point is set such that the touch point is separated from the target point; position information of the touch point is acquired; position information of the target point is calculated based on the position information of the touch point and the position relation between the touch point and the target point, and a position of the target point is displayed; and a confirmation operation is performed according to the displayed position of the target point. A device for implementing click and location operations on a touch screen is further disclosed. With the disclosure, the problem that it is difficult to precisely click and locate when the distance between the operation objects is very small can be solved.
1. A method for implementing click and location operations on a touch screen, comprising:
setting a position relation between a touch point and a target point such that the touch point is separated from the target point;
acquiring position information of the touch point;
calculating position information of the target point based on the position information of the touch point and the position relation between the touch point and the target point, and displaying a position of the target point; and
performing a confirmation operation according to the displayed position of the target point.
2. The method according to claim 1 , further comprising:
before performing the confirmation operation according to the displayed position of the target point,
when determining, according to the displayed position of the target point, that the position of the target point needs to be fine-tuned, moving a touch object and re-acquiring the position information of the touch point; and
re-calculating the position information of the target point based on the re-acquired position information of the touch point and the position relation between the touch point and the target point, and displaying the re-calculated position of the target point.
3. The method according to claim 1 , wherein the performing a confirmation operation according to the displayed position of the target point comprises:
leaving, by a touch object, the touch screen, so as to confirm the position of the target point; or
touching and then leaving, by a touch object, the touch screen, so as to confirm the position of the target point.
4. A method for implementing click and location operations on a touch screen, comprising:
setting a position relation between a touch point and a target point such that the touch point is separated from the target point;
acquiring position information of the touch point;
calculating position information of the target point based on the position information of the touch point and the position relation between the touch point and the target point, and displaying a position of the target point; and
performing a confirmation operation according to the displayed position of the target point,
further comprising:
after acquiring the position information of the touch point,
determining, according to the position information of the touch point, whether the touch point is located in an area where a precise click and location is required; and
when the touch point is located in an area where a precise click and location is required, calculating the position information of the target point based on the position information of the touch point and the position relation between the touch point and the target point.
5. The method according to claim 4 , further comprising:
before performing the confirmation operation according to the displayed position of the target point,
when determining, according to the displayed position of the target point, that the position of the target point needs to be fine-tuned, moving a touch object and re-acquiring the position information of the touch point; and
re-calculating the position information of the target point based on the re-acquired position information of the touch point and the position relation between the touch point and the target point, and displaying the re-calculated position of the target point.
6. A device for implementing click and location operations on a touch screen, comprising:
a location information setting module configured to set a position relation between a touch point and a target point such that the touch point is separated the target point;
a location information acquiring module configured to acquire position information of the touch point;
a location information feedback module configured to: calculate position information of the target point based on the position information of the touch point and the position relation between the touch point and the target point, and display a position of the target point; and
an operation confirming module configured to perform a confirmation operation for a user according to the displayed position of the target point.
7. The device according to claim 6 , wherein
the location information acquiring module is further configured to, when a user determines, according to the displayed position of the target point, that the position of the target point needs to be fine-tuned and when the user moves a touch object, re-acquire the position information of the touch point; and
the location information feedback module is further configured to re-calculate the position information of the target point based on the re-acquired position information of the touch point, and display the re-calculated position of the target point.
8. The device according to claim 6 , wherein
the operation confirming module is configured to, when a touch object leaves the touch screen, confirm the position of the target point; or when the touch object touches and then leaves the touch screen, confirm the position of the target point.
9. A device for implementing click and location operations on a touch screen, comprising:
a location information setting module configured to set a position relation between a touch point and a target point such that the touch point is separated the target point;
a location information acquiring module configured to acquire position information of the touch point;
a location information feedback module configured to: calculate position information of the target point based on the position information of the touch point and the position relation between the touch point and the target point, and display a position of the target point; and
an operation confirming module configured to perform a confirmation operation for a user according to the displayed position of the target point, wherein:
the location information feedback module is further configured to: determine, according to the position information of the touch point, whether the touch point is located in an area where a precise click and location is required; and
when the touch point is located in an area where a precise click and location is required, calculate the position information of the target point based on the position information of the touch point and the position relation between the touch point and the target point.
10. The device according to claim 9 , wherein
the location information acquiring module is further configured to, when a user determines, according to the displayed position of the target point, that the position of the target point needs to be fine-tuned and when the user moves a touch object, re-acquire the position information of the touch point; and
the location information feedback module is further configured to re-calculate the position information of the target point based on the re-acquired position information of the touch point, and display the re-calculated position of the target point.
