Abstract: 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.
