- the processor can calculate the intersection of the straight line L1 and the straight line L2, the intersection of the straight line L1 and the straight line L2 equation, the intersection of the straight line L1 and the straight line L3, respectively, according to the equation of the straight line L1, the equation of the straight line L2, and the equation of the straight line L3. Since the pointing point of the interactive device on the sensing screen is fixed during this sampling period, the above three intersection points coincide. The intersection of the three straight lines is the pointing point of the interactive device on the sensing screen during the aforementioned sampling period.
- S03. Determining the pointing point of the interactive device on the sensing screen according to multiple linear equations determined by multiple sampling in a sampling period includes:
