Abstract
A method for performing input sensing using an input device includes: receiving, at a sensing region of the input device, an input; obtaining, via receivers of the input device, measurements corresponding to the input, wherein obtaining the measurements comprises: separately driving multiple subsets of transmitters of the input device, and obtaining measurements corresponding to each separately-driven subset of transmitters via the receivers, wherein each separately-driven subset of transmitters comprises a plurality of non-contiguous transmitters; and generating, by a processing system of the input device, an image of the input based on the obtained measurements.
Claims20
A method for performing input sensing using an input device, the method comprising:
- receiving, at a sensing region of the input device, an input;
- obtaining, via receivers of the input device, measurements corresponding to the input, wherein obtaining the measurements comprises:
- separately driving multiple subsets of transmitters of the input device, and obtaining measurements corresponding to each separately-driven subset of transmitters via the receivers, wherein each separately-driven subset of transmitters comprises a plurality of non-contiguous transmitters;
- and
- generating, by a processing system of the input device, an image of the input based on the obtained measurements.
An input device, comprising:
- a surface corresponding to a sensing region, wherein the sensing region is configured to receive an input;
- transmitters, configured to be driven with transmitter signals;
- and
- receivers, configured to obtain measurements corresponding to the input, wherein obtaining the measurements comprises:
- obtaining measurements corresponding to separately-driven subsets of transmitters via the receivers, wherein each separately-driven subset of transmitters comprises a plurality of non-contiguous transmitters;
- and
- a processing system, configured to generate an image of the input based on the obtained measurements.
A non-transitory computer-readable medium having processor-executable instructions stored thereon for performing input sensing using an input device, the processor-executable instructions, when executed, facilitating performance of the following:
- obtaining, via receivers of the input device, measurements corresponding to an input received at a sensing region of the input device, wherein obtaining the measurements comprises:
- separately driving multiple subsets of transmitters of the input device, and obtaining measurements corresponding to each separately-driven subset of transmitters via the receivers, wherein each separately-driven subset of transmitters comprises a plurality of non-contiguous transmitters;
- and
- generating an image of the input based on the obtained measurements.
