The virtual glasses are generally connected to the computer by a USB cable and an HDMI cable, the first being used for communication with the PC, the second transmitting the image to the helmet. a computer, connected to the headset, to run the simulation (optional depending on the model).lenses to distance the user from the screen.VR headsets usually consist of several components: The 3D sound feedback plays a fundamental role in that matter, since it allows objects to be located in space. In order to be persuasive, the various elements presented must react according to the user’s position and orientation. Unlike augmented reality, which inserts virtual information into an existing landscape, virtual reality is based on virtual technology.

Most of the time, these are created on computers using specific software such as Unreal Engine or Unity. For immersion to work, the associated environment must be as credible as possible. Video games and animated films have accustomed us to 3D. Indeed, if the device jerks or does not follow the movements correctly, the user will easily come out of the immersion. a low response time between the system and the action. Therefore, headsets should have a minimum of latency, i.e. The stability of the system guarantees a convincing experience. The feeling of immersion emerges when the quantity and quality of the data received by the user coincide. The more senses the device deceives, the more real the experience will seem to our brain. The whole point of virtual reality lies in this illusion. Its fundamental purpose is to make our senses believe that what we are experiencing is not fictitious, but part of a reality. To immerse the user, virtual reality should deliver a realistic transcription of all these parameters.Īn image alone cannot convey the everyday experience, which is why VR headsets are combined with other devices, such as audio headsets. A scene is made up of an image, an associated sound, the touch of the materials around, but also the surrounding smell. Since then, the range of products on the market has grown and the fields of application of virtual reality are becoming increasingly diverse. The 2010s will open a new era for VR with the explosion of the video game field and the technological revolutions that led to the Oculus Rift, the Virtuix Omni, the Google Cardboard or the Samsung Gear VR. The 1990s saw the commercialisation of numerous headsets with unfinished technologies, leading to the disappointment of a public with feverish expectations. This device, nicknamed Darth Vader because of its shape, is used to simplify the piloting of combat aircraft.
The army was also a pioneer in the development of VR, notably with the creation of the Super Cockpit or VCASS (Visually Coupled Airborne Systems Simulator). The helmet is then complemented by a voice recognition system and Dataglove accessories from VPL research. NASA produced the VIEW (Virtual Interface Environment Workstation) system, which provided a vertical viewing angle of 120° thanks to two 2.7 inch LCD screens. Nevertheless, the project failed to convince and it was not until the early 1980s that the first virtual reality headsets as we know them appeared. This device, presented in 1962, resembles an arcade terminal, had a wind tunnel to simulate the wind and even a perfume diffuser. The ancestor of virtual reality is attributed to Morton Heilig and his Sensorama machine, which invites the user to call upon several senses. What principles are behind virtual reality headset? In this article we explain the origin of 3D glasses, how they work and what they are used for. The potential of VR is constantly evolving, so much so that it is disrupting our daily lives as its fields of application multiply. Thus, these devices make the dream of new horizons accessible with a complete and captivating sensory experience. The surroundings can then be walked through, creating a sense of immersion. Virtual reality (VR) is defined as a technology that produces a three-dimensional simulation of an environment.
