How VR and AR work – basics, overview and examples

In today’s world, digital information is essential. Digital processes constantly happen around us, without us being able to absorb them with our senses. But thanks to virtual and augmented reality as an extension of our senses, we can see digitally into the future – the article explains the basics, gives an overview and illustrates with examples.

When stores offer VR apps for bathroom planning, how to seduce women and explaining the female orgasm, this is a sure sign that the subject of Virtual Reality (VR) has reached the public. Data glasses and the interactive experiences that make them possible are not only interesting for bathroom planning and games, but also in the professional environment. Virtual reality connects the world of data and bits with reality and makes it tangible.

The history of data glasses

In 1838, the British physicist Sir Charles Wheatstone discovered how spatial vision works. He discovered that he could create a three-dimensional impression with two images, each shown to one eye and differing in perspective. Today’s data glasses, which are nothing more than two screens positioned directly in front of the eyes and each showing images for the left and right eye, are also based on this knowledge.

Virtual reality connects the world of data and bits with reality and makes it tangible. When DIY stores offer VR apps for bathroom planning, this is a sure sign that the subject of virtual reality has reached the public. Data glasses and the interactive experiences that make them possible are also interesting for the professional environment. Thanks to immersive experiences, the viewer can move through the virtual world and interact with it.

Many of us still know the Viewmaster, in which one could insert cardboard discs with stereoscopic pictures and then view the Tadsch Mahal or the Golden Gate Bridge three-dimensionally. Unfortunately this was a static view. Today, it is possible to create a three-dimensional model of a landscape, a factory building or even a car interior and, with the help of a virtual stereo camera, calculate a view at any point.

Introducing data glasses into the company in just five steps

Wearable Computing – Bodyworn Computers, Smart Watches and Head-Mounted Displays (HMD) – booming. But how can the introduction of data glasses technology be successfully implemented in the company? Ubimax, provider of wearable computing and augmented reality solutions, describes this in five steps.

 

By combining these two things and equipping the data glasses with sensors that measure head movements, you can develop an immersive experience in which the viewer can move through the virtual world and look around completely naturally. This is exactly what VR glasses do. In addition, the viewer gets devices in his hand, which are also tracked in their position and position and which bring his hands into the virtual world. Thus he can grasp things, press buttons or open virtual doors.

What an immersive experience is

The word „immersive“, penetrating, immersing, describes it well: the observer slips into the virtual world and the mind very quickly gets involved in the virtual environment. There is an experience in which one balances virtually on a board between two skyscrapers.

  1. Even though you know that you are walking on a board that lies on the floor and the whole environment is computer-generated, many people get a fear of heights.
  2. Besides such „full-length“ glasses, which completely shield people from reality, and data glasses like Google Glass, which only display data in one corner of the field of view, there is a wide range of applications from „completely virtual“ to „almost completely real“.
  3. This is called Augmented Reality (AR). Depending on the field of application, these technologies offer interesting application possibilities.

When virtual reality is used

Virtual reality, i.e. completely computer-generated worlds, naturally offers itself when it comes to visualizing and investigating things that do not yet exist or no longer exist. Long before the Dresden Frauenkirche was built, there was a VR experience in which one could move through the finished church. VR has also established itself, for example, in interior design – be it in bathrooms such as the do-it-yourself store or vehicle interiors. The designer and developer immediately gets a very realistic impression of his product.

 

Configuring the awning with the Augmented Reality App

A good example of an AR application is an app developed by Warema, a specialist for technical sun protection products, in cooperation with the Ellwangen-based system house Inneo. After the start, the prospective customer marks three points on his terrace by approaching the points with his mobile phone camera. The software then projects an awning into the camera image, which always remains in the same position even when the telephone is swivelled. The user can now select the awning fabric and model and test different configurations and dimensions. He always sees the virtual awning on the real house wall on the smartphone screen. At the end, he can create a PDF that contains all the data and a photo of the AR model and with which he can order the awning from the specialist dealer.
