HOW DOES AR/VR WORK?

How Does Augmented Reality Work?

To show the relevant content to the user AR uses computer vision, simultaneous localization, mapping, and depth tracking (sensor data calculating the space to the objects). this enables cameras to gather, send, and process data so as to point out digital content relevant to what the user is watching.

For augmented reality to start out working cameras must-see things be capable enough to work out what they’re seeing and further categorize it.

The whole process of computer seeing world includes the machine representing colors by numbers, identifying an identical group of colors then segmenting the image, checking outlines that meet at object angles and covering a selected a part of the image, finding textures, and matching the image with those present within the database.

Augmented reality requires discerning objects around the user in terms of both semantics and 3D geometry. Semantics recognizes the thing, while geometry figures out where the thing is placed.

Why Does AR Need Computer Vision?

For augmented reality to start working cameras must-see things be capable enough to figure out what they are seeing and further categorize it.

The whole process of computer seeing the real world includes the machine representing colors by numbers, identifying a similar group of colors and then segmenting the image, searching for lines that meet at object angles and covering a specific part of the image, finding textures, and matching the image with those present in the database.

How does virtual reality work?

As mentioned, VR requires several devices like a headset, a computer/smartphone, or another machine to make a digital environment, and a motion-tracking device in some cases. Typically, a headset displays content before a user’s eyes, while a cable (HDMI) transfers images to the screen from a PC. the choice option is headsets working with smartphones, like Google Cardboard and GearVR – a phone that acts both as a display and a source of VR content.

Some vendors apply lenses to vary flat images into three-dimensional. Usually, a 100/110-degree field of sight is achieved with VR devices. a subsequent key feature is that the frame rate per second, which should be 60 fps at a minimum to form virtual simulations look realistically enough.

What is VR?

Virtual reality (VR) may be a fresh interface unlike the traditional one, immersing an individual during a digital 3D environment, rather than watching on a display. Computer-generated imagery and content aim at simulating a true presence through senses (sight, hearing, touch).

Virtual reality simulation requires two main components: a source of content and a user device. Software and hardware, in other words. Currently, such systems include headsets, all-directions treadmills, special gloves, goggles. VR tools should be providing realistic, natural, high-quality images and interaction possibilities. For this, devices believe measurements like:

  • image resolution,
  • field of view,
  • refresh rate,
  • motion delay,
  • pixel persistence,
  • audio/video synchronization.

The main challenge of VR is tricking the human brain into perceiving digital content as real. that’s tough, and this “immersion” issue is what still holds computer game experiences back from being enjoyable. for instance, the human field of vision doesn’t work as a video frame, and besides about 180 degrees of vision, we even have a sight.
