Abstract
Official abstract text for this publication.
The embodiments described herein thus provide devices and methods that facilitate improved input devices. Specifically, the devices, systems and methods provide the ability to accurately determine user input using multiple different sensing regimes. The different sensing regimes can be used to facilitate accurate position determination of objects both at the surface and away from the surface. For example, the different sensing regimes can be used to determine position information for both ungloved and gloved fingers. In one embodiment the first sensing regime uses a first duty cycle of absolute capacitive sensing and a first duty cycle of transcapacitive sensing. The second sensing regime uses a second duty cycle of absolute capacitive sensing and a second duty cycle of transcapacitive sensing, where the second duty cycle of absolute capacitive sensing is greater than the first duty cycle of absolute capacitive sensing.
First claim
Opening claim text (preview).
What is claimed is: 1. A processing system for an input device comprising: a sensor module comprising sensor circuitry, the sensor module configured to: operate a plurality of capacitive sensor electrodes to selectively perform transcapacitive sensing and absolute capacitive sensing to detect objects in a sensing region; and a determination module configured to: determine positional information for input objects in the sensing region by selectively operating the processing s…
