‘Technological nature' ... you may have heard this term... it's a term used to describe a picture of a natural scene that’s been produced using computer graphics so that basically it isn't a real view - say of a garden or field - it's a virtual one - it's a picture that looks like a real scene, Now, looking at scenes of nature is known to have an effect on people's health and well-being. So for someone who's ill, for a patient in a hospital, does a virtual view of a garden have the same impact as a real one? Does it have the same beneficial effects when you look at it? Because that would be good. Well, um, if you test this out, if you put a group of people in a room with a real view and another group of people in a room with a virtual view - an unreal view - you can see what happens when they get stressed. If you give both groups a task that is slightly stressful and increases their heart rate and, um, what you'll find is that the people who have the real garden scene outside their window to look at - their heart rate goes back to normal more quickly than those of the people in the other group who only have a virtual view to look at. So, yes, there is a difference - people's recovery from stress is faster in the room with the real view.
