Unlike virtual reality, augmented reality lets you synchronize reality with visuals from digital technology in real time. It’s a technology made to synchronize digital and physical worlds. It’s great because it provides information in real-time and blends in with the real world with privacy.
Users usually need a screen that can deliver information and integrate it with the real life environments, like smart glasses, cellphones, and even contact lenses. But there is projection based augmented reality as well, which uses synthetic light to show visuals as well. People can also refer to projection based augmented reality as holograms.
Augmented reality components are simply broken down into three different categories. Input based hardware, processing hardware/software, and output hardware. Input based hardware are sensors that capture information about the real world like cameras, compasses, gyroscope, GPS. Processing hardware and software are used to interpret data acquired through these sensors. Then we have output hardwares which displays the information like smart glasses. Augmented reality uses simultaneous localization and mapping, which allows digital content to be accurately synchronized with the real world.
When a user turns on augmented reality, it first uses a camera and other sensors to capture the user’s environment. The data that is captured then has to then be processed, so augmented reality software can decide where to place the user’s requested data. The software will have to define the object and decide where to generate digital visuals to let you peer inside the body. After deciding what visuals to show, the augmented reality software will synchronize with the live environment and place it where requested.
The augmented reality software has to understand the real world for it to synchronize properly. From horizontal and vertical surfaces and planes to motion detecting, it has to capture numerous data and have to process it real time before displaying the digital visuals.
Let’s talk about one of the simplest forms of augmented reality. Marker based AR which uses a photo or QR code to initiate AR animation will scan the “marker” with a camera. The marker is set to activate the augmented reality. The marker is going to be static, meaning it won’t move from that spot. However, the user can move around it and it allows for a 3D view. This is frequently used in museums, where one can use a phone to scan a specific spot and pull up augmented reality. Then we have markerless augmented reality, which doesn’t have the limitation of it being in a fixed spot, then we have a step beyond that which is superimposition based augmented reality which is just marker-less with smarter technology like object detection.
