Abstract
This disclosure is directed at least in part to sensing movement of an electronic display and canceling perceived movement of content on the electronic display in response to the sensing. A display manager may reassign “physical pixels” to “image pixels” (or virtual pixels) such that the image appears to be stationary while the physical pixels are moving due to movement of the electronic display. For example, if the physical pixels are moving upward, the image pixels may be reassigned downward in an equal and opposite manner. The user's persistence of vision may then be reinforced by reassignment of the pixels by the display manager. For example, text displayed on the electronic display may be more readable and images more easily viewed by a user.
