Abstract

The invention discloses a linearity testing device which comprises a controlled module and a control module, wherein the controlled module receives a control signal, reads a feedback coordinate of a mobile track produced on an object to-be-tested according to a preset coordinate, and generates a feedback signal according to the feedback coordinate; the control module receives the feedback signal, and compares the feedback signal with the control signal by the Pythagorean theorem or the normal theorem algorithm to calculate the error value between the feedback coordinate and the preset coordinate, so as to test the mobile track linearity. The invention further discloses a linearity testing method which comprises the following steps: planning the mobile track, and/or setting the error value range and the distance measuring way of the mobile track, and/or calculating the error value between the feedback coordinate of the mobile track and the preset coordinate according to the Pythagorean theorem or the normal theorem algorithm on the basis of the set distance measurement way, and if the error value is within the error value range, the mobile track meets the linearity testing standard.

Description

technical field [0001] The present invention belongs to a linearity testing device and method, in particular to a linearity testing device and method which uses an algorithm to calculate the return coordinate and preset coordinate error value of a moving track. Background technique [0002] With the rapid advancement of technology, various lightweight and miniaturized electronic products are constantly being introduced, especially smart electronic devices, such as smart phones and tablet computers, which are different from previous electronic devices. Smart electronic devices are the largest The selling point is that various functions such as phone calls, business affairs, and entertainment can be performed through touch control. In order to meet the diverse needs, in addition to the traditional single-touch control, a multi-touch control method has been developed today. The so-called Multi-touch means that the user can achieve image application control input technology thro...
