Introduction
The concept of AR lies in blending together the real objects around us with virtual or imaginary ones that can be added dynamically to the world. Augmented Reality is picking up the heat nowadays. What if you could place a digital version of a scaled car right in front of you? AR or Augmented Reality is a live view of a physical world whose elements are enhanced by computer-generated information. There are some fundamental technologies that allow applications to understand the real world. Let's get familiar with some of them:
Motion Tracking
This allows the system to understand and track its position relative to the real world. The things which are near to our eyes look bigger in size compared to the things which are far away from our eyes. By exploiting the motion tracking and calculating the distance between the user and any point in space, the system can decide what should be the size of any imaginary object at that point in space.
Environmental Understanding
Environmental understanding simply means understanding the real-world environment by detecting feature points and flat surfaces. Using proper environmental understanding, one can place the virtual object in the real surrounding in order to analyze different aspects. It defines the boundaries, which are then later used to analyze the environment.
Light Metering
In the physical world, every object has a different amount of shining and has shadows of different lengths and shapes based on the light source's direction and intensity of the light near that object.AR application can utilize this light information to calculate the size and the direction of the shadow for any object at any point in space.
Surface Detection
Surface detection is one of the applications of AR. Surface detection lets learners place a 3D model of any object onto a tabletop or floor surface in front of them. They can then do whatever they want to do with objects like move, rotate, etc.
Benefits of surface detection
The major advantage of surface detection is that it places a real-sized digital model in front of learners. The parts of the object are developed all up to scale, which better prepares the learners to encounter the real object. Apart from this, learners can learn from anywhere just by placing the digital object in the surrounding.AR plane detection provides a unique learning experience.
