Compact AR/VR optical-display hardware.

Abstract

Implementations of an augmented reality (AR)-capable display device for displaying light generated by a display onto a predefined field of view are disclosed herein. Within one implementation, the display device comprises a mount assembly configured to removably attach with a mobile computing device associated with the display, to thereby arrange the display with a predefined position. The display device further comprises an optical arrangement having a predefined arrangement relative to the predefined position and defining the field of view. The optical arrangement comprises a first mirror element configured to reflect a first portion of first incident light that is based on the light generated by the display, and a second mirror element disposed within the field of view and configured to reflect, onto the field of view, a second portion of second incident light that is based on the first portion.

Background

BACKGROUND Field of the Disclosure (1) The present disclosure generally relates to computer-based entertainment, and more specifically to optical arrangements suitable for augmented reality (AR) and/or virtual reality (VR) display devices. Description of the Related Art (2) Computer graphics technology has significantly progressed since the first video games were developed. Relatively inexpensive 3D graphics engines now provide nearly photo-realistic interactive game play on hand-held video game, home video game, and personal computer hardware platforms costing only a few hundred dollars. These video game systems typically include a hand-held controller, game controller, or, in the case of a hand-held video game platform, an integrated controller. A user interacts with the controller to send commands or other instructions to the video game system to control a video game or other simulation. For example, the controller may include a joystick and buttons operated by the user. (3) While video games allow the user to interact directly with the video game system, such interactions primarily influence the graphical depiction shown on the video game device (or on a connected display), and rarely influence any other objects outside of the virtual world. That is, a user may specify an input to the video game system, indicating that the user's avatar should perform a jump action, and in response the video game system could display the user's avatar jumping. However, such interactions a

Claims

1. An augmented reality (AR)-capable display device for displaying light generated by a display onto a field of view, the display device comprising: an optical arrangement having a positioning relative to a predefined position of the display and defining the field of view, the optical arrangement comprising: a first mirror element configured to reflect at least some display light generated by the display as first reflected display light, wherein the first mirror element comprises a dichroic beam splitter, which splits incident light based on wavelength; a second mirror element configured to reflect at least some of the first reflected display light reflected by the first mirror element as second reflected display light, wherein the second mirror element comprises a second dichroic surface configured to reflect red, green, and blue wavelengths; and a third mirror element configured to reflect at least some of the second reflected display light reflected by the second mirror element through the first mirror element and onto the field of view. || 10. A method, comprising: reflecting, using a first mirror element of a display device, at least some display light generated by a display as first reflected display light, wherein the first mirror element comprises a dichroic beam splitter, which splits incident light based on wavelength; reflecting, using a second mirror element of the display device, at least some of the first reflected display light reflected by the first mirror element as second reflected display light, wherein the second mirror element comprises a second dichroic surface configured to reflect red, green, and blue wavelengths; and reflecting, using a third mirror element of the display device, at least some of the second reflected display light reflected by the second mirror element through the first mirror element and onto a field of view.
