Abstract
Systems, methods, and devices for reducing shadow effects in touch systems are contained herein. In one aspect, a method of reducing shadow effects in a touch system is disclosed. The method includes receiving a touch input on a touch interface, determining a difference between a weighted mean of the touch input and an arithmetic mean of the touch input and adjusting an estimated touch position of the touch input based on the difference.
