Accuracy (Measurement)

The purpose of the TSM is to report the position of a physical object. The accuracy (in short) is the difference between the reported and the physical position of the object (finger) in front of the TSM. The touch accuracy of the TSM can be described statistically with the normal distribution and a standard deviation of 2 sigma. This means that the touch position reported by the sensor module will deviate less than the specified value in 95% of the cases, when the whole object (finger) is inside the Touch Active Area.
