Head-Mounted Display Device With Vision Correction

The patent application describes a head-mounted display with a display system and an optical system in a housing. The display system includes displays that produce images, and positioners move the displays relative to the user's eye positions. An adjustable optical system with tunable lenses allows the displays to be viewed through the lenses when the user's eyes are at the correct positions. A sensor measures refractive errors in the user's eyes using waveguides, volume holograms, and a camera to gather light reflected from the retinas.

Potential Commercial Applications

Potential commercial applications of this technology include gaming headsets, medical devices for vision correction, training and simulation tools, and industrial applications for enhanced visualization.

Possible Prior Art

One possible prior art for this technology could be existing head-mounted displays with adjustable lenses for vision correction. Another could be eye-tracking systems used in virtual reality devices to improve user interaction.

Unanswered Questions

How does the sensor accurately measure refractive errors in the user's eyes?

The sensor uses waveguides, volume holograms, and a camera to gather light reflected from the retinas, but the specific technology and algorithms used for this measurement are not detailed in the abstract.

What are the specific applications in the military sector for this technology?

While the abstract mentions military applications for enhanced vision, it does not provide specific examples or details on how this technology could be utilized in military settings.

Original Abstract Submitted

a head-mounted display may include a display system and an optical system in a housing. the display system may have displays that produce images. positioners may be used to move the displays relative to the eye positions of a user's eyes. an adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. the displays may be viewed through the lenses when the user's eyes are at the eye positions. a sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. the sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.
