Abstract: Pressure compensation can be used to improve performance of force-sensitive touch screens. Changes in pressure, particularly transient, internal pressure changes in an electronic device due to an object applying force to a touch screen of the electronic device, can degrade force sensing performance of the touch screen. For example, when a finger presses a force-sensitive touch screen of a sealed electronic device, the applied force can increase internal pressure of the sealed electronic device until internal pressure can equalize. The increased internal pressure can cause a normal force to oppose the deflection of the touch screen, resulting in inaccurate force measurements of applied user force. In some examples, an electronic device including a force-sensitive touch screen can include a pressure sensor configured to measure internal pressure of the electronic device. The measured pressure can be used to compensate the amount of force measured by the force sensor.

Abstract: This relates to methods and apparatus for estimating an object profile to improve accuracy of touch sensor panel input (e.g., reducing input position wobble for a stylus or finger translating on a surface over and between electrodes of a touch sensor panel). In some examples, the object profile estimation can begin with an initial profile estimate that can allow the object profile estimation to converge for a large range of possible input object sizes, shapes, distances, and/or orientations. The object profile information can use data from multiple frames of data acquisition as well as multiple pixels in the panel to construct the object profile estimate based on the input measurement. Specifically, the object profile can be estimated by measuring the object at various positions relative to touch pixels or nodes and gaps between touch pixels or nodes over multiple frames of sensor data and combining the measurement data of the multiple frames.
