Each virtual reality lenses, are an essential part of each project that is presented to users, the models vary according to the conditions of use. Technically they are called “augmented reality viewers” ​​and without them it would be impossible to enjoy virtual reality and the new trends in video games.

Virtual reality glasses

The glasses or lenses of the virtual reality are part of the essence of this technology. They are called HDM «Head-mounted display» in Spanish VR virtual reality viewer; They are devices that are placed on the user's head and are shaped like lenses.

Through them, you can view images created by means of a computer, which contains program advanced in imaging; in this way, images and videos are reproduced very close to the eyes and are directed directly to the person's retina; likewise, some need a application for virtual reality glasses

However, to know how virtual reality glasses work, it is necessary to understand that the images that are generated are very similar to the real ones, with them it is possible to increase their size and create realities similar to the true ones in the user.

Our Story

The first projects arrived at the beginning of the year 1991 through the SEGA company, being the first to present the "El Sega VR", although it was never sold; other companies during that decade dedicated time to the development of projects such as Forte VFX1; and Sony offered the Glasstron in 1997.

These glasses or lenses were linked to video games where every year versions with applications more innovative. Users felt new experiences, however, they will not be able to fully position themselves in the market, however, by the 2000s, various versions of glasses developed by Sony and SEGA companies appear.

The market was stagnant and the creators were wondering: What are virtual reality glasses for? ? This led them to expand the areas of use; resources were offered for various fields of science such as medicine, engineering, architecture, aeronautics, as well as in the sport and other scientific specialties that continue in the development of virtual reality.

However, the proposals did not come to fruition and there was no room for them. In this way, the companies devoted themselves exclusively to creating virtual reality lenses for entertainment; today there are some renowned companies such as SONY, Facebook y Google.

These corporations present projects like the Oculus Rift; which is a virtual reality lens that serves as a support for other video games; Sony launched the PlayStation VR. 9; Valve company also made some lens proposals, but the market remains stable.

Types of virtual reality glasses

To really know how virtual reality glasses work, it is important to know the types. In this way, it is possible to decide which are the most suitable, Consequently, some come according to the way in which the images are reproduced in the eyes, or simply in a single eye let's see:

  • Binocular, this virtual reality lens projects the images on both eyes allowing a wider definition and more precise coordination.
  • Monoculars, are those that focus on the projection of images towards one of the eyes; These devices are not created for games in virtual reality, it is only developed by Google for its products.

According to its shape

  • Basic helmets are large and occupy almost the entire field of vision, allowing you to create an interesting virtual reality.
  • Augmented reality helmets are similar to the previous ones and have the characteristic of increasing reality up to 3 times its real size, with them a true experience is achieved.

According to its operability

  • Moving lenses, they have the appearance of a shell or helmet, they lack their own screen, they work through mobile phone, which has the support to reproduce the images; Among the most used are Gear VR of Samsung and Google Cardboard
  • Lenses without a processor, these have their own screen that includes sensors that help connect with an external device, such as a personal computer, which sends the images to the lenses.
  • Self-contained lenses, including larger components such as housings, screen, sensors and processors, are expensive but very complete.

Models

The virtual reality glasses come in different models that can serve to satisfy the needs of the players; remember that today VR technology is dedicated to entertainment. Let's see some of these models:

  • Lenses, are devices that connect to a computer or cell phone come with built-in screens and among the most important are Oculus Rift, PlayStation RV, HoloLens, VIve, StarVR, FOVE VR.
  • Lens type housings are used in most cases together with the latest generation mobile phones, among the most important are Gear VR, Cardboard, Daydream View, plastic housings and other materials.
  • Early models, still in use, offer basic visuals and interface, such as Forte VFX1, Virtual Boy, 3D Visor and eMagin Z800

Each team is adapted and linked through electronic elements such as Leap Motion, PrioVR, Glove One, STEM System or PowerClaw controllers. Similarly they use model peripherals such as Virtuix Omni, Cyberith Virtualizer.

However, Google has presented a very interesting innovation, and it is how to make homemade virtual reality glassesUsing cardboard and plastic materials, users can develop their own virtual reality lensesAlthough, as expected, they will not have the efficiencies of electronic equipment.

Features

These lenses have unique conditions and specifications, which determine how they should be used:

  • They come with important screen resolution.
  • The field of view is quite wide.
  • Low latency or delay is generated.
  • They have good orientation and position tracking.
  • Keeps eye tracking steady and there is no deviation.
  • Stereo vision.
  • There is no separation of screens due to pixelation effect.
  • Some have the ability to generate 3D effects.
