Systems and methods for parallax compensation

摘要

An electronic device may include a touch screen electronic display configured to offset and/or shift the contact locations of touch implements and/or displayed content based on one or more calculated parallax values. The parallax values may be associated with the viewing angle of an operator relative to the display of the electronic device. In various embodiments, the parallax value(s) may be calculated using three-dimensional location sensors, an angle of inclination of a touch implement, and/or one or more displayed calibration objects. Parallax values may be utilized to remap contact locations by a touch implement, shift and/or offset displayed content, and/or perform other transformations as described herein. A stereoscopically displayed content may be offset such that a default display plane is coplanar with a touch surface rather than a display surface. Contacts by a finger may be remapped using portions of the contact region and/or a centroid of the contact region.

主权项

1. An electronic device, comprising:
an electronic display configured to display content; a touch screen digitizer having a touch surface aligned with the electronic display, the digitizer configured to detect contacts by a touch implement with the touch surface; and a parallax calculation module configured to: display a plurality of touch-inducement objects on the electronic display; identify an intended contact location of the touch implement on the electronic display corresponding to each of the plurality of touch-inducement objects; receive a plurality of contact locations of the touch implement with the touch surface, each associated with the display of one of the touch-inducement objects; calculate distance offsets between each of the plurality of contact locations of the touch implement with the touch surface and the respective intended contact locations; calculate parallax values for each of the plurality of contact locations of the touch implement with the touch surface using the calculated distance offsets; derive a parallax value for each of a plurality of potential contact locations of the touch implement with the touch surface, including a first parallax value for a first of the plurality of potential contact locations and a second parallax value for a second of the plurality of potential contact locations, wherein the first parallax value is different than the second parallax value; and offset a plurality of display locations of subsequently displayed objects based on the derived parallax values, including the first and second parallax values.
