A method includes sampling output from sensor having electrode junctions integrated on a device including a display, detecting capacitance between the device ground and a user (C) based on the output sampled and a pre-defined model, and defining one of two grounding states of the device based on the capacitance detected. Output is processed based on the grounding state defined and touch coordinates are determined based on the output processed. The touch coordinates are reported to a controller of the display.

System and method for detecting grounding state of a touch enabled computing device

A device includes a display, a controller configured to control the display, a sensor integrated with the display and a circuit a circuit in communication with the sensor. The sensor is configured to sense touch input and the circuit is configured to detect when a user is gripping the device only based on output from the sensor and a pre-defined model. Gripping is reported to the controller.

System and method for detecting grip of a touch enabled device

A method includes detecting a signal emitted by a stylus with a digitizer sensor, determining coordinates of the stylus, identifying a hover operational mode based on input received by the stylus, detecting a capacitive effect of a tip of the stylus on the digitizer sensor and reporting a touch operational mode of the stylus based on the capacitive effect detected. The capacitive effect of the tip of the stylus on the digitizer sensor is based on mutual capacitive detection and is performed in a defined area around the coordinates determined.

Soft touch detection of a stylus

A device includes a display displaying data, a digitizer sensor including a plurality of conductive elements spread across the display and a circuit connected to the plurality of conductive elements. The circuit transmits data displayed on the display via at least one of the conductive elements of the digitizer sensor. The conductive elements of the digitizer sensor are electrically isolated from one another.

Method and system for data transfer with a touch enabled device

A method includes detecting a first signal on first electrodes along a first axis of a digitizer sensor, detecting a second signal on second electrodes along a second axis of the digitizer sensor, determining that hand input exists over the first electrodes based at least on the first signal and no hand input exists over the second electrodes. A first phase of the first signal detected on the second electrodes is determined. A second phase of the second signal detected on the first electrodes is estimated based on the first phase and a portion of the first signal associated with the second phase is extracted. Coordinates of a handheld device is determined based on the portion of the first signal extracted from the first electrodes and the second signal and the coordinates are reported to a host computing device associated with the digitizer sensor.
