1. A touch-sensitive display system for an electronic device, comprising:
- a touch-sensitive display comprising a touch-sensitive surface; and
a control module configured to;
receive contextual information from an application during at least an initialization of the application and a state change of the application;
determine a plurality of regions based on contextual information from the application, the plurality of regions being mapped to the touch-sensitive surface;
determine an expected touch screen input method for each of the plurality of regions based on the contextual information, the expected touch screen input method being one of a coarse input method and a fine input method; and
adjust one or more of a scanning sensitivity and a resolution sensitivity for each of the plurality of regions of the touch-sensitive surface based on the expected touch screen input method such that the accuracy and Quality of Service (QoS) of the touch-sensitive display for the fine input method is higher than the accuracy and QoS of the touch-sensitive display for the coarse input method.

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.
