Method for syncing different touching systems

摘要

A method for syncing different touching systems uses a computer, which is electrically connected with a first input device and a second input device respectively and in which an input of the first input device is controlled by the second input device, to make the first input device and the second device synchronous. The method includes defining at least one correction point on the first input device; receiving time tags of signal inputs at the correction points of the first input device and the second input device respectively; calculating time differences for each time tag at each correction point with respect to other correction points; averaging all time differences for all correction points to determine a deviation value; and delaying a signal transmission of the second input device according to the deviation value.

1. A method using a computer to sync two different touch systems, wherein the computer is electrically connected with a first input device and a second input device respectively, the second input device controls an input of the first input device, the computer comprises a storage device for storing a software program and a processor for executing the software program to achieve the following steps:
defining at least one correction point on the first input device; receiving a first time tag from the first input device, when the second input device controls the input of a first correction point of the first input device, the first time tag is the time when a first input signal is received from the first correction point, wherein the first correction point is one of the at least one correction point; receiving a second time tag, when the second input device controls the input of the first correction point of the first input device, the second time tag is the time when a second input signal is received from the second input device; calculating a first time difference between the first time tag and the second time tag to determine a deviation value; delaying a signal transmission of the second input device according to the deviation value; calculating a number of the inputs of the first input device controlled by the second input device to determine whether a predetermined accumulated point is reached for syncing the first input device and the second input device; if the predetermined accumulated point is reached, then receiving a fifth time tag, when the second input device controls the input of the predetermined accumulated point of the first input device, the fifth time tag is the time when a fifth input signal is received from the predetermined accumulated point; receiving a sixth time tag, when the second input device controls the input of the predetermined accumulated point of the first input device, the sixth time tag is the time when a sixth input signal is received from the second input device; calculating a third time difference between the fifth time tag and the sixth time tag; determining whether the third time difference is larger than the deviation value; if the third time difference is larger than the deviation value, then repeating the correction steps for the at least one correction point.
