Virtual Reality Development with Unity

Virtual Reality has been picking up since the announcement of the Oculus Rift in 2015. Today VR is accessible by using Oculus Rift,  Samsung Gear VR, HTC Vive , soon to be launched Google’s Daydream and lowest cost option, Google Cardboard.  In addition, companies have started investing in building new products in this space and many showcased their solutions in the CES 2016 expo including Sony, SoftKinetic, Virtuix, etc.
Going forward, Virtual Reality will be more and more interesting and will start empowering our day to day lives, and would change our behavior and thinking patterns, and so the decisions! You need to start thinking how it will impact your business too….

Types of Virtual Reality Experiences

There are many VR apps and experiences for education, travel, music and more, but not all experiences are computer-generated. A new type of camera captures images, records video and audio in 360º. This immersive video puts you at the center of the action, and gives you the freedom to look anywhere in your environment. An example would be you sitting on your couch of your home and attending a pre-recorded event or live training session happening in a different country.

Interacting with a VR App

Interacting with VR apps is easy once you get the hang of it.  Most apps use one of two interaction methods. The first and simplest is gaze-based interaction. You simply look at what you want to select, and hold your gaze on it for a second or two. The second type of interaction is by using a wired or Bluetooth controller connected to the mobile. In this case, you’d look at what you want to select, then press a button to select it. The controller can also be used to perform an action like pausing a video or controlling a character.

Working with a Mobile VR

Your iOS or Android smartphone becomes the window to the virtual world. Once inserted into the Google Cardboard or Samsung Gear VR, your phone tracks your head movement, so you’re able to look up, down and all around in a virtual environment. In addition to head tracking, VR apps also split the screen into left and right images that appear in 3D when viewed through the Google/Samsung headset. Together with headtracking, this 3D effect creates a feeling of immersion, making you feel as if you’re actually experiencing the same.

Uses of Virtual Reality

Virtual Reality can be used for depicting real-life experiences in a variety of industries, including:

  • Education – To teach and collaborate in virtual classrooms.
  • Medicine – To understand anatomy and travel into the human brain or to tackle your fears.
  • Travel – To fly. Be free in space or explore holiday destinations.
  • Real Estate – To get a virtual tour of the houses, gardens and apartments of your future homes.
  • Entertainment – To play games and watch all those eye-catching animated movies.
