Abstract:
Implementations disclosed herein provide systems and methods for improved processing of touch sensor data with improved scalability and reduced standby power. Touch-related algorithms may be partitioned between the touch screen controller and the application processor or host such that the system can function with low standby power and low interface bandwidth while providing a scalable solution for enhanced user experience. In some aspects, a small digital processing engine and memory remains in the analog front end (AFE) of the touch screen controller to perform imagine forming algorithms that are mostly related to noise reduction and filtering schemes.
Abstract:
Systems and methods for context-based touch-sensing and processing are disclosed. The energy-efficiency of a touch sensitive device may be improved by dynamically adjusting the function of the touch sensitive surface in real-time based on contextual information such as expected QoS, expected user input in defined regions-of-interest of the touch sensitive surface, and usage modalities of the touch sensitive device.
Abstract:
Methods, systems, computer-readable media, and apparatuses for recognizing touch input for a touch panel are presented. In some embodiments, a method for recognizing touch input for a touch panel includes scanning the touch panel over a first frame including at least one touch panel blob resulting from a touch on the touch panel. The method also includes scanning the touch panel over a second frame including at least one touch panel blob resulting from a touch on the touch panel. The method additionally includes processing the touch panel blob within the first frame based at least in part on a first touch-reporting sensitivity and processing the touch panel blob within the second frame based at least in part on a second touch-reporting sensitivity. The method further includes determining whether a valid touch exists based at least in part on the processing step.
