摘要： Systems and methods are disclosed for determining a touch position from data received from a touch panel. In one implementation, an apparatus for processing a touch input signal includes a processor that may be configured for parallel processing, a touch device, a memory, operably connected to the processor, and configured to store processor instructions. The processor instructions can configure the processor to receive a plurality of data points corresponding to a plurality of touch events on the touch device, determine a center of mass estimate from the plurality of data points, determine a search radius of center of mass estimate, and determine an optimal touch point position based on the center of mass estimate and the search radius using the processor.

摘要： 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.

摘要： Systems, methods, and devices for correcting the position of a touch input near the edge of a touch screen. The method includes receiving a touch input, determining the centroid of the touch input, if the centroid is determined to be near the edge of the display panel, correcting the location of the centroid.

摘要： Lower report rates are desirable in touch devices to minimize power consumption. However, lower report rates lead to inaccurate and untimely depiction of a user's touch inputs on a touch display device. Disclosed are methods and apparatus for using a lower report rate; while maintaining substantially the same or better user experience achieved by using a higher report rate.
