VIRTUAL reality set-ups need a computer, console or smartphone to run the app or game, a headset which presents a display before your eyes – which can be the phone's display – and input such as head or hand tracking.
The tracking system connected to a computer adjusts images so that the wearer is shown a realistic environment with a realistic depth of perception.
The tracking needs to be as accurate as it can be or else the illusion breaks down.
Glasses and headsets enable the wearer to see three-dimensional images such as being able to view a high building at different angles and the sense of moving through the structure.
The glasses enable the wearer to see two separate images which the brain combines into one.
Virtual Reality Society website said this is what gives the illusion of 3D depth, often accompanied by sounds which add to the experience.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
