1. A touch-sensitive system for an electronic device, comprising:
- a touch-sensitive surface;
an environmental sensor; and
a control module configured to;
continuously acquire data regarding an environmental condition from the environmental sensor; and
dynamically adjust one or more of a scan rate, a scan region, and a touch sensor excitation signal of the touch sensitive surface based on the sensed environmental condition.

Abstract
Systems and methods for host-augmented touch-sensing are disclosed. The energy-efficiency of a touch sensitive device may be improved by dynamically adjusting the scanning sensitivity of the touch sensor based on host-augmented environmental information such as temperature, pressure, position, orientation, humidity, force, or battery charging mode.
