Virtual reality adaptive display control

Abstract

Apparatus, systems, articles of manufacture, and methods for adaptive display control in virtual reality environments are disclosed. An example virtual reality display device for adaptive display control in a virtual reality environment includes memory and a processor to execute instructions to detect a first pupil size after a predetermined amount of time, determine a characteristic of a display image, identify a second pupil size from a plurality of pupil sizes correlated with the characteristic of the display image, perform a comparison of the first pupil size and the second pupil size, determine a margin of difference between the first pupil size and the second pupil size, and adjust the characteristic of the display image to change the first pupil size and reduce the margin difference.

What is claimed is: 
     
         1 . A virtual reality display device comprising:
 memory; and   a processor to execute instructions to:
 detect a first pupil size after a predetermined amount of time; 
 determine a characteristic of a display image; 
 identify a second pupil size from a plurality of pupil sizes correlated with the characteristic of the display image; 
 perform a comparison of the first pupil size and the second pupil size; 
 determine a margin of difference between the first pupil size and the second pupil size; and 
 adjust the characteristic of the display image to change the first pupil size and reduce the margin difference.
