Abstract: An input device (100) is configured to detect force being applied to an input region (120) of the device (100) by an input object (140), in addition to the position of the input object (140) using touch sensing methods. The input device (100) applies a position-based jitter force filter to the force sensor data to compensate for a non-uniform response across the input device (100), as well as the movement of an input object (140).

Abstract: A capacitive sensing device is configured to detect force being applied to an input surface of the device by an input object, in addition to the position of the input object using touch sensing methods. Embodiments generate a compensation factor that is used to determine the force information in order to compensate for physical changes to the capacitive sensing device over time, air-gap non-uniform distribution, and other mechanical variations and changes.

Abstract: This disclosure generally provides an input device, electronic systems and processing system for touch sensing. In one example, an input device for touch sensing includes receiver electrodes and transmitter electrodes arranged in transmitter and receiver electrode columns. Each transmitter electrode within each transmitter electrode column is paired with two adjacent receiver electrodes of a first column of the receiver electrode columns. A first plurality of traces couple a first group of receiver electrodes in the first receiver electrode column, the first plurality of traces not passing between the transmitter and receiver electrodes of the first transmitter and receiver electrode columns. A second plurality of traces coupled a second group of receiver electrodes in the first receiver electrode column, the second plurality of traces passing between one of the transmitter electrodes of the first transmitter electrode column and one of the receiver electrodes of the second group of receiver electrodes.

Abstract: A method of operating a force-sensitive input device having an input surface comprises declaring a first press action upon detecting an amount of force applied to the input surface that exceeds a first no-press force value by at least a first press threshold value, determining a maximum force value applied to the input surface during the first press action, and setting a release threshold value for a subsequent release action based on the determined maximum force value.

Abstract: Embodiments described herein include a method for calibrating capacitive force sensors. The method includes measuring a force level at each of a first electrode and a second electrode. The method also includes determining an expected force level at the second electrode based on the measured force level at the first electrode and a force contribution ratio for the second electrode. The method includes determining a difference between the measured force level at the second electrode and the expected force level at the second electrode and adjusting a force weighting factor for the second electrode in response to the difference exceeding a predetermined threshold to create an adjusted force weighting factor. The method also includes adjusting the measured force level at the second electrode.

Abstract: Embodiments described herein include a method for calibrating capacitive force sensors. The method includes acquiring a plurality of changes of capacitance at a plurality of sensor electrodes in a capacitive sensor, where the plurality of changes of capacitance represents a force. The method also includes identifying a plurality of inflection points in the plurality of changes of capacitance, where each of the plurality of inflection points bounds a region of modeling. The method includes determining a modeling equation for each region of modeling, where the modeling equations are used for calibration of force sensing.
