Abstract

A method for display control and an electronic device are provided. The method includes: detecting a first touch operation and a second touch operation performed on a touch sensing unit. A first touch direction corresponding to the first touch operation and a second touch direction corresponding to the second touch operation are obtained. A first control instruction is obtained based on the first touch direction and the second touch direction. That is, in embodiments of the disclosure, the effect of a touch instruction response to two successively performed touch operations is different from the effect of a touch instruction response to two separately performed touch operations.

determining a minimum angle formed between the first touch direction and the second touch direction;

determining whether the minimum angle is less than or equal to a second preset threshold; and

obtaining the first control instruction to control display content to be displayed on the display unit, if the minimum angle is less than or equal to the second preset threshold.

7. The method according to claim 5, wherein if the display content to be displayed has an area larger than that of the display unit, the method further comprises:

moving the display content at a preset speed upon completion of the second touch operation, until a boundary of the display content is displayed on the display unit;

or

displaying the boundary of the display content on the display unit upon completion of the second touch operation.

8. The method according to claim 1, further comprising:

detecting a third touch operation and a fourth touch operation after the third touch operation;

determining a third touch track corresponding to the third touch operation and a fourth touch track corresponding to the fourth touch operation, wherein the third touch track is different from the first touch track and the second touch track, and the fourth touch track is different from the first touch track and the second touch track;

obtaining a third touch direction corresponding to the third touch operation and a fourth touch direction corresponding to the fourth touch operation; and

generating the first control instruction if the third touch direction is the same as the first touch direction and the fourth touch direction is the same as the second touch direction.

9. The method according to claim 1, wherein said obtaining the first control instruction based on the first touch direction and the second touch direction comprises:

determining a minimum angle formed between the first touch direction and the second touch direction;

determining whether the minimum angle is greater than or equal to a third preset threshold; and

generating the first control instruction to zoom in or zoom out display content to be displayed on the display unit, if the minimum angle is greater than or equal to the third preset threshold.

10. The method according to claim 1, wherein a time interval between a touch start time and a touch end time corresponding to each of the first touch operation and the second touch operation is less than or equal to a fourth preset threshold.

11. An electronic device, comprising:
