Abstract

Embodiments of the present invention provide a display control method and apparatus. The method includes: determining a distance between a user input part and a touch screen; if the distance is greater than a first threshold, performing no operation; and if the distance is smaller than or equal to the first threshold, adjusting a display scale of a clickable area on the touch screen. Thereby, the displaying of clickable areas on the touch screen may be improved, and misoperations of users may be reduced.

Claims

1. A display control method, comprising:

determining a first distance between a user input part and a touch screen;

if the first distance is greater than a first threshold, performing no operation; and

if the first distance is smaller than or equal to the first threshold, adjusting a display scale of a clickable area on the touch screen.

2. The display control method according to claim 1, wherein the adjusting the display scale of the clickable area on the touch screen comprises:

obtaining a projection area of the user input part on the touch screen;

increasing the display scale of the clickable area where a second distance between the clickable area and the projection area is smaller than or equal to a second threshold; and

reducing the display scale of the clickable area where the second distance between the clickable area and the projection area is greater than the second threshold.

3. The display control method according to claim 2, wherein the increasing the display scale of the clickable area where the second distance between the clickable area and the projection area is smaller than the second threshold comprises:

in the clickable area where the second distance between the clickable area and the projection area is smaller than the second threshold, increasing the display scale of the clickable area according to the second distance between the clickable area and the projection area.

4. The display control method according to claim 2, wherein the reducing the display scale of the clickable area where the second distance between the clickable area and the projection area is greater than the second threshold comprises:

in the clickable area where the second distance between the clickable area and the projection area is greater than the second threshold, reducing the display scale of the clickable area according to the second distance between the clickable area and the projection area.

5. A display control apparatus, comprising:

a determining unit, configured to determine a first distance between a user input part and a touch screen; and

an adjusting unit, configured to adjust a display scale of a clickable area on the touch screen if the first distance is smaller than or equal to a first threshold.

6. The display control apparatus according to claim 5, wherein the adjusting unit is further configured to:

obtain a projection area of the user input part on the touch screen;

increase the display scale of the clickable area where a second distance between the clickable area and the projection area is smaller than or equal to a second threshold; and

reduce the display scale of the clickable area where the second distance between the clickable area and the projection area is greater than the second threshold.

7. The display control apparatus according to claim 6, wherein the adjusting unit is further configured to:

in the clickable area where the second distance between the clickable area and the projection area are smaller than the second threshold, increase the display scale of the clickable area according to the second distance between the clickable area and the projection area.

8. The display control apparatus according to claim 6, wherein the adjusting unit is further configured to:

in the clickable area where the second distance between the clickable area and the projection area is greater than the second threshold, reduce the display scale of the clickable area according to the second distance between the clickable area and the projection area.

9. A device including a touch screen, comprising:

the touch screen, configured to receive a touch operation of a user and display a corresponding content to the user;

a processor, configured to perform corresponding processing according to the touch operation of the user; and

a display control apparatus, comprising;

a determining unit, configured to determine a first distance between a user input part and the touch screen; and

an adjusting unit, configured to adjust a display scale of a clickable area on the touch screen if the first distance is smaller than or equal to a first threshold.

10. The device according to claim 9, wherein the adjusting unit is further configured to:

obtain a projection area of the user input part on the touch screen;

increase the display scale of the clickable area where a second distance between the clickable area and the projection area is smaller than or equal to a second threshold; and

reduce the display scale of the clickable area where the second distance between the clickable area and the projection area is greater than the second threshold.

11. The device according to claim 10, wherein the adjusting unit is further configured to:

in the clickable area where the second distance between the clickable area and the projection area are smaller than the second threshold, increase the display scale of the clickable area according to the second distance between the clickable area and the projection area.

12. The device according to claim 10, wherein the adjusting unit is further configured to:

in the clickable area where the second distance between the clickable area and the projection area is greater than the second threshold, reduce the display scale of the clickable area according to the second distance between the clickable area and the projection area.
