Abstract
The method and device for position detection are disclosed. Corresponding to a first touch related sensing information, a second touch related sensing information is acquired for determining at least one position. Each position is used separately for determining the position of a centroid according to the first touch related sensing information or the second touch related sensing information.
Claims20
A method for determining centroid positions, comprising:
- obtaining a first touch related sensing information;
- obtaining at least one position;
- determining a corresponding first calculation range in the first touch related sensing information based on each position;
- determining a corresponding base value based on each first calculation range;
- generating a set of calculation values by subtracting the corresponding base value from all the values in each first calculation range;
- and
- calculating a centroid position based on each set of calculation values.
