Abstract

An immersive experience system is provided. The immersive experience system has a processor that determines a position of a first head-mounted display. Further, the processor determines a position of a second head-mounted display. The processor also generates a first image for a first immersive experience corresponding to the position of the first head-mounted display. Moreover, the process encodes the first image into a first infrared spectrum illumination having a first wavelength. In addition, the processor generates a second image for a second immersive experience corresponding to the position of the second head-mounted display. Finally, the processor encodes the second image into a second infrared spectrum illumination having a second wavelength. The first wavelength is distinct from the second wavelength.

Background

BACKGROUND Field (1) This disclosure generally relates to the field of audio/visual (“A/V”) equipment. More particularly, the disclosure relates to an A/V system that provides an immersive experience. General Background (2) Virtual reality (“VR”) and augmented reality (“AR”) are the two most common immersive experience technologies. Whereas a VR apparatus typically provides an immersive experience that is completely virtual, an AR apparatus typically provides a virtual experience in conjunction with a real-world experience (e.g., an overlay of various text and/or images over a real-world object, person, place, etc.). (3) Typically, a head-mounted display (“HMD”), such as headgear, glasses, etc., is worn by the user over his or her eyes to provide a VR or an AR experience. Yet, wearing the HMD can be quite uncomfortable for a user. For instance, the HMD can be quite heavy as a result of onboard sensor-fusion componentry that track the head position of a user, and processors built-in to the HMD to adjust the content displayed by the HMD based on the corresponding head position. Even when the processing componentry is positioned within a stand-alone computer rather than the HMD, the user will typically be tethered to the stand-alone computer via a backpack or one or more cables, thereby providing an added layer of inconvenience to the user. Therefore, conventional HMDs may not be optimal for immersive experience environments. SUMMARY (4) In one aspect, an immersive experience sy

Claims

1. A head-mounted display comprising: a display area; a photodetector; a plurality of light emitting diodes (LEDs) configured to emit a first plurality of infrared spectrum illuminations, the first plurality of infrared spectrum illuminations identifying the head-mounted display from a plurality of head-mounted displays; an optical bandpass filter configured to filter a second plurality of infrared spectrum illuminations from an optical emission device according to a predetermined wavelength such that a filtered infrared spectrum illumination is absorbed by the photodetector, the optical emission device emitting the second plurality of infrared spectrum illuminations responsive to an identification of the head-mounted display using the first plurality of infrared spectrum illuminations emitted from the plurality of LEDs; and a projector configured to project an image onto the display area, the image being stored in the filtered infrared spectrum illumination. || 13. A method comprising: emitting, with a plurality of light emitting diodes (LEDs), a first plurality of infrared spectrum illuminations identifying a head-mounted display from a plurality of head-mounted displays, the plurality of LEDs being coupled to the head-mounted display; filtering, with an optical bandpass filter, a second plurality of infrared spectrum illuminations from an optical emission device according to a predetermined wavelength that is associated with the first plurality of infrared spectrum illuminations corresponding to the head-mounted display; absorbing, with a photodetector coupled to the head-mounted display, a filtered infrared spectrum illumination; and projecting, with a projector coupled to the head-mounted display, an image onto a display area of the head-mounted display.
