Abstract: In one embodiment, a method includes accessing a first image and a second image, where at least part of the first image overlaps with at least part of the second image. The first and second images are divided into portions associated with a first set of grid points, where each grid point in the first set corresponds to a portion of the first image or the second image. Differences in the region of overlap between the first and second images are determined. One or more grid points in the first set and the corresponding portions of the first image or the second image are moved relative to one or more other grid points in the first set based on the determined differences.

Abstract: In one embodiment, a method includes generating, at a multi-view display, a first content to be viewed at a first angle and a second content to be viewed at a second angle. The first content and the second content are displayed simultaneously. The method also includes receiving, at a touch-screen panel coupled to the multi-view display, a first plurality of capacitive signals. The method then generates, by the touch-screen panel, a first touch-screen panel heatmap based on the received first plurality of capacitive signals. The method afterwards determines, based on the first touch-screen panel heatmap, whether a first user input is received with respect to the first content or the second content. The method then assigns, based on determining the first user input corresponds to either the first content or the second content, the first user input to the first content or the second content.
