Abstract: In some examples, an electronic device including a touch screen can sense a stylus proximate to the touch screen. For example, the user can draw or write with the stylus to create a simulated drawing or simulated handwriting displayed on the touch screen. In some examples, the electronic device can sense a series of “points” corresponding to the location of the stylus over time while the drawing/writing input was provided. In some situations, noise in the stylus data can cause the electronic device not to sense one or more noisy points included in the drawing or handwriting input. In some examples, the electronic device can interpolate the noisy points based on sensed points before and/or after the time of the skipped points.

Abstract: Obstruction detecting logic may execute touch-sensing algorithms on the electronic device, which may detect when a user is gripping the electronic device from the side, when the fingers or hand of the user is on the edge of the electronic device, when the user is using one or more fingers to touch the electronic device, and may determine thumb and finger orientation. Using the touch-sensing methods, it may be determined which antennas are obstructed. To mitigate negative antenna performance due to the determined obstruction, one or more compensation actions may be taken. The touch-sensing algorithms may estimate user thumb/finger orientation and velocity, which may be used to predict future antenna occlusion (e.g., if the hand of the user is in motion).
