Claim 0:
1. A method for operating a device, the method comprising:
operating a sensor including sensor lines arranged along a first axis and along a second axis to form a grid; and
prior to scanning any of the sensor lines, identifying user interactions on the sensor;
based at least on identifying the user interactions:
sampling, by a circuit in communication with the sensor, first outputs of the sensor responsive to simultaneously triggering the sensor lines along the first axis with a same signal over a first stage of detection without sampling the sensor lines along the second axis; and
selecting, by the circuit, a second set of the sensor lines along the second axis that indicate a presence of the user interactions based on the first outputs sampled;

triggering, by the circuit, based on a multi-touch detection method, only the second set of the sensor lines over a second stage of detection to receive second outputs; and
determining, by the circuit, positions of the user interactions on the sensor from the second outputs.
