Head-mounted display belongs to what equipment head-mounted display display principle

Many consumers are very curious about the head-mounted display, this display is not common in daily life, its technical content is still very high, a small instrument contains a variety of scientific and technological innovations and electronic components, to give consumers beyond the physical and mental experience of the senses. So what kind of equipment belongs to the head-mounted display, head-mounted display display principle, head-mounted display has been connected but not positioned what is going on? Below please come together to understand it.

A, head-mounted display belongs to what equipment

1, head-mounted display is a new type of display, is worn on the head of a device. One feature of a head-mounted display is two small optical screens in front of the eyes. In some types of head-mounted displays, a video screen is used instead of these two small screens Head-mounted displays are considered a virtual reality device that can be used both for behavioral research and for work or task performance, which can display images into the line of sight, combining images with the natural world.

2. The head-mounted display HMD was developed by the Fraunhofer Institute for Optical Microsystems in Germany. It is shaped like eyeglasses, but by sensing people's eye activity, receiving instructions and presenting images. All the mystery is on the chip inside the display, allowing you to read all kinds of data directly on the glasses.

Two, head-mounted display display principle

1, the principle of the helmet display is a small 2-dimensional display of the image produced by the optical system to amplify. Specifically, the light emitted by the small display through a convex lens so that the image is refracted to produce a similar effect in the distance.

2. This effect is utilized to magnify near objects for viewing at a distance to achieve the so-called holographic vision. Liquid crystal displays (small cathode ray tubes were used in the early days, and organic electroluminescent display devices have been used recently) pass the image through an eccentric free-form lens, making the image similar to a large screen.

3, due to the eccentric free-form surface lens for a tilted concave lens, so optically it is not only a lens function, basically has become a free-form prism. When the image generated by the image into the eccentric free-form prism surface, and then the total reflection to the viewer's eyes to the side of the concave mirror.

4. The side concave mirror surface is coated with a layer of mirror coating, reflecting and at the same time the light is once again amplified and reflected back to the eccentric free-form prism surface, and correcting the tilt of the light on that surface to reach the viewer's eyes.

Third, the head-mounted display is connected but not positioned

If the HTCvive use environment with obvious reflective objects, this situation will occur, the reason is because the lighthouse uses the principle of laser reflection on the headset and other equipment for positioning, if the environment with such reflective objects, such as mirrors, reflective ground with a strong reflective object will affect the HTCvive's normal work, so make sure there are no such reflective objects when enabling HTCvive.

The above is brought to you by the editor on the head-mounted display belongs to what equipment, head-mounted display display principle, head-mounted display has been connected but not positioning related to the introduction.
