Abstract
Aspects of the disclosed apparatuses, methods and systems provide three-dimensional gradient and dynamic light fields for display in 3D technologies, in particular 3D augmented reality (AR) devices, by coupling visual accommodation and visual convergence to the same plane at any depth of an object of interest in real time.
Claims13
A vision system comprising:
- a first display configured to present an image, formed by a plurality of first pixels emitting light from the first display, the image comprising at least one object represented by one or more first display object pixels comprised in the first pixels;
- a second display configured to present the image formed by a plurality of second pixels emitting light from the second display, the at least one object represented by one or more second display object pixels comprised in the second pixels;
- an optical element arranged at a first distance from the first display and at a second distance from the second display to project light emitted from the first display corresponding to the image in a first focal plane and to project light emitted from the second display corresponding to the image in a second focal plane;
- and
- a processing device configured to control an intensity of the one or more first display object pixels relative to the intensity of the one or more second display object pixels to create a perception of the at least one object between the first focal plane and the second focal plane, wherein the relative intensity between the one or more first display object pixels and the one or more second display object pixels is controlled such that
- if the at least one object is to be perceived closer to the first focal plane than to the second focal plane, the first display object pixels have a higher intensity than the second display object pixels, and
- if the at least one object is to be perceived closer to the second focal plane than to the first focal plane, the second display object pixels have a higher intensity than the first display object pixels.

A vision system comprising:
- a display divided into at least two different portions including at least a first portion configured to present an image, formed by a plurality of first pixels emitting light from the first portion, the image comprising at least one object represented by one or more first portion object pixels comprised in the first pixels and a second portion configured to present the image formed by a plurality of second pixels emitting light from the second portion, the at least one object represented by one or more second portion object pixels comprised in the second pixels;
- a multifocal optical element including a first focus arranged to project light emitted from the first portion of the display corresponding to the image in a first focal plane and a second focus arranged to project light emitted from the second portion of the display corresponding to the image in a second focal plane;
- and
- a processing device configured to control an intensity of the one or more first portion object pixels relative to an intensity of the one or more second portion object pixels to create a perception of the at least one object between the first focal plane and the second focal plane, wherein the relative intensity between the one or more first portion object pixels and the one or more second portion object pixels is controlled such that
- if the at least one object is to be perceived closer to the first focal plane than to the second focal plane, the first portion object pixels have a higher intensity than the second portion object pixels, and
- if the at least one object is to be perceived closer to the second focal plane than to the first focal plane, the second portion pixels have a higher intensity than the first portion object pixels.
