Abstract
An optical position tracking device and a method of testing the same are provided. The device includes: a controller for generating at least one test operation signal in response to a command signal; a test signal generator for generating a test signal during a test operation in response to the test operation signal; a motion calculator for receiving the test signal during the test operation and performing operations in response to the test operation signal to output an output signal; and an output signal analyzer for determining whether the output signal is correct during the test operation in response to the test operation signal to output a result signal. Thus, the complexity of the method of testing the optical position tracking device can be markedly reduced and it is unnecessary to employ a high-performance test apparatus. Further, the time taken to test the optical position tracking device can be shortened by simplifying and optimizing test circumstances, and a test can be performed by connecting the optical position tracking device with a typical system, such as a personal computer (PC), instead of exclusively employing a test apparatus.
