1. A processing system coupled with an input device, comprising:
- a sensor module, the sensor module configured to;
perform a first low-power scan to detect a first input object in a sensing region of the input device; and
a determination module, the determination module configured to;
determine, using the first low-power scan, a type of input object corresponding to the first input object in the sensing region, andcompare the type of input object with a predetermined set of input object types to determine whether the first input object is an object of interest based on whether the type of input object is among the predetermined set of input object types;
when the first input object is the object of interest, perform, by the sensor module, a first high-power scan of the sensing region, andwhen the first input object is an object of no interest, perform, by the sensor module, a second low-power scan of the sensing region.

Abstract
A method may include performing a first low-power scan to detect an input object in a sensing region of an input device. The method may further include determining, using the first low-power scan, whether the input object is an object of interest. The method may further include performing a high-power scan of the sensing region when the input object is an object of interest. The method may further include performing a second low-power scan of the sensing region when the input object is an object of no interest.
