Abstract

The present disclosure provides a method and a device for moving a cursor of a television. The method includes: obtaining a two-dimensional code value of a two-dimensional code reading device on a two-dimensional code graph paper in real time; calculating absolute coordinates of the cursor according to the two-dimensional code value and a position of the current cursor; and re-displaying the cursor according to the absolute coordinates. The present disclosure realizes the movement of the cursor through two-dimensional code technology, which reduces the difficulty of the operation and is suitable for use to satisfy people'"'"'s requirements.

Claims

1. A method for moving a cursor of a television, comprising:

obtaining a two-dimensional code value of a two-dimensional code reading device on a two-dimensional code graph paper in real time;

calculating absolute coordinates of the cursor according to the two-dimensional code value and a position of the current cursor; and

re-displaying the cursor according to the absolute coordinates.

2. The method of claim 1, wherein the step of calculating absolute coordinates of the cursor according to the two-dimensional code value and a position of the current cursor comprises:

obtaining a relative value of the movement of the two-dimensional code reading device on the two-dimensional code graph paper according to the two-dimensional code value, and calculating the absolute coordinates of the cursor according to the relative value and the position of the current cursor.

3. The method of claim 1 further comprising following steps before the step of re-displaying the cursor according to the absolute coordinates:

temporarily storing the absolute coordinates;

when there are at least two of the absolute coordinates being temporarily stored, synthesizing the absolute coordinates and temporarily storing the synthesized absolute coordinates as new absolute coordinates; and

reading the new absolute coordinates which are temporarily stored.

4. The method of claim 3 further comprising the following step after the step of reading the new absolute coordinates which are temporarily stored:
