Abstract
A handheld device for use with a digitizer sensor includes a writing tip, an integrated circuit configured to generate a signal, a first electrode separated from the writing tip along a longitudinal axis of the handheld device, and a relative angle detection element configured to provide information for determining an angle of the handheld device relative to the digitizer sensor. The first electrode is electrically coupled to the integrated circuit and configured to transmit the signal to the digitizer sensor.
Claims20
A system comprising:
- at least one memory device;
- at least one processing device;
- a stylus position detection engine stored in the memory and executable by the processor to:
- receive first input from a digitizer sensor indicating a position of one or more signal-receiving electrodes of the digitizer sensor interacting with a first signal-emitting electrode of a handheld device including a writing tip, the first signal-emitting electrode separated from the writing tip by a distance along a longitudinal axis of the handheld device;
- receive second input from a relative angle detection element of the handheld device;
- calculate a position of a writing tip of the handheld device relative to the digitizer sensor based on the position of the one or more receiving electrodes of the digitizer sensor and the second input.

- a first electrode separated from the writing tip along a longitudinal axis of the handheld device, the first electrode electrically coupled to the integrated circuit and configured to transmit the signal to the digitizer sensor;
- and
- a relative angle detection element configured to provide position information for determining an angle of the handheld device relative to the digitizer sensor, the position information usable to calculate a position of the writing tip relative to the digitizer sensor.
A method comprising:
- detecting first input at one or more receiving electrodes of a digitizer sensor included in an electronic display, the detected first input transmitted by a first signal-emitting electrode of a handheld device that is separated from a writing tip of the handheld device by a distance along a longitudinal axis of the handheld device;
- detecting second input from a relative angle detection element of the handheld device;
- calculating a position of the writing tip of the handheld device relative to the digitizer sensor based on a position of the one or more receiving electrodes of the digitizer sensor and the second input.
