Virtual reality (VR) is an interactive computer-generated representation for real world or activity, and Mixed Reality (MR) is an interactive combination of real-world and computer-generated features. Both of them are changing the way we live and work and the rapid advancement of technology makes the development of VR and MR more varied and rich.

VR games are completely digital and in a computer-generated environment. Players mainly use the advanced VR headsets or goggles to control themselves. Here are some popular VR devices:

1. Oculus Quest 2

SG$431.39 in Amazon Singapore. It is seamless all- in-one system and can connect to PCs.

2. Oculus Rift S

SG$549.87 in Amazon Singapore. It has great game library and built-in room tracking. However, the PC is required.

3. PlayStation VR

SG$750 in Amazon Singapore. It is easy to set up and visually sharper.

4. HTC Vive

SG$1740 in Amazon Singapore. It has the best immersive experience with smooth graphics and little latency.

The VR device I choose is Oculus Quest2. It is lighter and smaller than original version, with 46% more processing power, 33% more graphics processing power and 50% more RAM. It has sensitive controllers, high-resolution image, quick refresh rate and long battery life. Moreover, it is very cost-effective. 64GB will cost US$299 and 256GB will cost US$399. This device can feel like it could expand a wider field of view and has amazing sense of immersion.

MR has digital content to interact the users’ environment in real time. Therefore, MR must be viewed through semi-transparent glasses or MR headsets with a camera in order to display the users’ environment.

Here are some popular MR devices:

  1. Magic Leap One ($2295)
  2. Microsoft HoloLens (S3000)
  3. Nreal Light ($1000)
  4. Occipital Bridge ($399)

The device I choose is Nreal Light released in 2019 from China. It has 1920 x 1028 px resolution and the field of view (FOV) is 52 degrees. The main advantage of this device is fashionable design and light weight. It uses SLAM (Simultaneous Localisation and Mapping) algorithm to achieve inside-out tracking and two onboard cameras for seamless MR experience.
