Embodiment Construction
[0029] see figure 2 . figure 2 It is a schematic diagram of detecting the position variation of multiple inputs received by a multi-touch device in the present invention after midpoint calculation. The capacitive sensor array is used to detect a first input touch point marked as "one finger point" and a second input touch point marked as "two finger point". Initially, in the pre-acquired screen, the first input is located at the first position , and the second input is located at the second position . After the second input moves the position, the post-acquisition screen shows that the second input is at the third position , while the first input remains at the fourth position near the first position, and every The center point in a picture will be calculated. For example, in the first acquired frame, the midpoint between the first position and the second position will be calculated. For example, the midpoint is the first central position , and =. Similarly, in the pos...
