Elements – The Computer Screens & Vision

Let’s start with the screen you have in front of you right now. Your sharp vision area is tiny while your peripheral vision is wide, soft but highly sensitive to motion/change in light.

There is also a secondary border of the visual field, about the size of a large computer screen, where what is within this area has a higher bandwidth to our brains than what is outside it. This is likely down to the speed and effort of the six extraocular muscles which control movement of the eye. As you can ‘see’, you can move your eyes quite far off centre before you have to engage your neck, but there is a more comfortable zone more directly in front of you. Computer gamers find that screens which covers this area provides for a more effective gaming view with faster reflexes possible within this area.

So now we have 3 areas to consider for the visual impulses from our work environment and the upside is that a 15”-21” or so computer screen is not such a bad core work area, where augmentation from secondary displays for secondary information can of course be useful and should be considered. The main point however, is that let’s not simply push for VR and photorealistic renderings of all kinds of things as being the holy grail of information environments – we can also do wondrous things with the medium sized rectangle we all use every day.
