How many touched points can be detected by MTR touch screen at a time?
Up to 2 points can be detected at a time. When 3 or more points are touched, only the first 2 points are detected, and other points are ignored. There are some limitations of the multi-touch function. These are described below.
a. Multi-touch within a cell is not supported. When multiple points are touched within a single cell at a time, the middle point is detected.
b. When 4 points are touched at one time, and the points formed a square (see a to d below), the touched points are not detected correctly. Avoid such touch operations.
