Everyone has some idea of ??what VR (virtual realityaugmented reality
So what is AR and how does augmented reality work? We will answer both of these questions right now.
Compared to AR, VR, and MR
Augmented reality is one of the technologies in the family of technologies. It is joined by virtual reality and mixed reality, known as “XR” or augmented reality . Augmented reality refers to the entire spectrum of reality-altering technologies, from fully virtual worlds to full integration between the real and the virtual. The border between these three points of the spectrum is fuzzy, but the basic definitions look something like this:
- Virtual reality completely immerses you in the virtual world, replacing what you see and hear
- Extended reality superimposes digital information on what you see in real life.
- Mixed Reality fully integrates digital sounds and images with the real world.
The border between AR and MR is the most fuzzy. For example, a heads-up in a car or inside a motorcycle helmet technically qualifies as augmented reality On the other hand, much of what is called augmented reality today is actually firmly in the mixed reality spectrum. Therefore, in this article, we will include mixed reality as part of the discussion.
Tag-based, tag-based, and location-based augmented reality
Augmented reality applications usually require some way to sense the outside world in order to have a reference point for visualization and sound. There are three approaches to this:
- marker-based AR uses a predefined object in the real world and maps AR content to it.
- AR without markers can use arbitrary objects in the real world as anchor points or does not require anchoring at all.
- Location-based AR is triggered when the user is in a specific location, such as various locations in a zoo or museum
Many early augmented reality experiments require markers. For example, games like The Eye of Judgment used a camera attached to a Playstation 3 to bring paper playing cards to life. You will also see marker-based AR with objects such as movie posters or QR codes in books.
The real progress in AR / MR technology is associated with markerless methods, which deserve a separate more detailed discussion.
AR and MR tracking technologies
If you give a computer system an accurate real-time map of a space, such as a room, you can visualize graphics associated with that space. It seems that these virtual objects exist in the real world.
Initially, the main way that developers tried to achieve the ideal of markerless augmented reality was by integrating sophisticated sensors into devices such as smartphones. These include laser systems, scanning objects and surfaces, stereoscopic cameras, infrared sensors, sonars, and more.
Google Project Tango was a prime example of this approach. An augmented reality hardware platform that has been included in several phones and tablets. Technology developed in projects such as Tango was critical to the AR we use today, but the cost and complexity of these specialized devices have seen their demise. However, Apple computers may have had something to do with it.
AR and MR for mobile devices
While Google was working on Tango, Apple made a bombshell in the form of ARkit A software platform that can create markerless, persistent augmented and mixed reality experiences using nothing more than standard cameras on existing iPhones and iPads
With sophisticated machine vision algorithms, iOS app developers could easily embed augmented reality functionality into their software. This made Project Tango’s dedicated hardware approach obsolete in no time.
Google ultimately responded with the ARCore API, which allows Android app developers to do more or less the same thing as on iOS using ARKit. Both of these resources for programmers have created a stable and reliable foundation for bringing mobile augmented reality to market. This lowered the bar for both users and developers.
AR and MR hardware products
While ARKit and ARCore make high-quality augmented reality possible on virtually any modern smartphone, that doesn’t mean the idea of ??dedicated augmented or mixed reality hardware is dead.
First, phones are now equipped with sensors that make augmented reality better. Apple’s latest iPad Pro models are equipped with a LiDAR sensor. This is the same 3D sensing technology used by robots and self-driving cars. Presumably future iPhones will also receive this new miniature version of the technology.
Some VR headsets now use head-mounted cameras for tracking as well as for mixed reality applications. Windows Mixed Reality headsets are specifically designed for this purpose. There are also persistent rumors about Apple’s AR headset, supposedly the ultimate goal of their ARKit development, LiDAR technology and the acquisition of many AR companies.
We also have existing high quality augmented reality headsets like Magic Leap and Microsoft Hololens However, these impressive devices have a price tag, and if you ask how much, it’s probably too much. For now, these headsets are targeted at businesses and educational institutions. However, you can rest assured that consumer-grade versions will hit the market sooner or later, just like with high-end VR.
Cool augmented reality apps that you can try right now
What’s really great about augmented and mixed reality is that you don’t have to just read about it. Most of our readers have access to smartphones or tablets, which means you can go to the respective app stores and try them out now!
Whether you are using an iPhone or Android phone, we recommend trying Pokemon Go first. This addictive approach to the PokÃ©mon formula forces you to travel the real world and encounter wild PokÃ©mon that you must then capture. These cute critters are projected into the real world using augmented reality It seems as if they are present in your space.
Ikea Place is a nifty app that lets you see how the Ikea furniture you looked after will actually look like in your home. A really useful AR app!
In iOS, MeasureKit is a paid augmented reality utility that allows you to quickly determine the size of objects in the real world. On Android, you can get a similar Measure tool for free. Anyway, no more guessing!
Boost your life!
The future of augmented reality may be much more important than we think. If augmented reality head units become small enough to produce images of sufficient quality, they can replace any other type of display in existence. Imagine a world where TVs or computer monitors are no longer needed because your personal AR glasses can simply project a virtual TV onto the wall.
In the long run, augmented reality technology can eliminate the need to decorate your home or for companies to place billboards or other physical visuals around the world. The world with advanced AR technologies available can be very different from what we know today!
