Virtual reality (VR) is the computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors.
A person using virtual reality equipment is able to "look around" the artificial world, and (with high quality VR) move in it and interact with virtual features or items. VR headsets are usually head-mounted goggles with a screen in front of the eyes. Programs may include audio and sounds through speakers or headphones.
Not everyone has access to VR technology; however, there are some clever solutions available. The most common tool used to create a VR experience is a mobile phone with a gyroscopic sensor.
Other suggested specifications:
- 4.7 to 5.5 inch/12-14 cm screen (to get immersive experience)
- 1080p display (for image quality)
- 2 GB RAM
- Minimum CPU speed of 1.4 GHz
If you have a smartphone, but no access to a VR headset, you can build one yourself using pretty basic materials.
