Title: Innovations of Chun-Chao Chang
Introduction
Chun-Chao Chang is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of optical touch sensing technology. With a total of four patents to his name, his work has advanced the capabilities of touch interfaces in various applications.
Latest Patents
One of his latest patents is an optical touch sensing device and a touch signal determination method. This invention includes a light source module, at least one image capturing element, and a processing unit. The light source module, positioned on a touch surface, emits detecting light to the surface. The image capturing element captures optical touch data based on this detecting light. The processing unit then recognizes the optical touch data according to a recognition threshold to obtain multiple touch signals. Notably, if the object spacing between the touch signals is no larger than a palm spacing, the processing unit compares the covering parameters of the touch signals to select the largest covering parameter. It then determines whether to ignore the touch signal corresponding to this parameter based on a defined area threshold.
Another significant patent involves an optical touch module and a method for determining gestures. This method includes obtaining sensing results from two optical sensors that continuously monitor a touch area from different corners. A gesture is determined based on the centers of the touch reference points from the sensing results.
