But isn't that what I say.
Brain sorts out background and concentrates on what's on screen.
Now I am confused: I thought your whole point was that gaming on a semi-see through screen is the next big thing, because this way you would know whats going on in the real world while playing > "these allow immediate interaction with real world when needed."
But this video proves that while you are gaming (=concentrating on the ball) your brain does filter out most of whats hapenning otherwise (= the real world). So how does the situation change with a semi transparent screen in comparison to a todays screen? You still will be focused on the game, while theoretically the world around you could go havoc.
Because the brain is capable of that.
When brain does not expect the humans to be in th game then it will seperate it from game.
Also it's not only about that.
The leg/shoe of other passengers are in the background.
If you focus on the screen your eye can't have the background sharp as well.
So it's not even possible to be distracted by that.
Take some transparent foil and place it in front of your eye (about 20 cm I'd say).
Now focus on that and turn on the TV in about 2-3 meters distance.
Your eye can't focus both so there won't be any serious interference (At least for the eye screen. Don't know how distracting the small screen is if you focus distance).
And don't forget it's a game that will need all your attention and not a static picture that will allow easy habituation.
You don't need a sharp image of something to get distracted. Whats essential is motion in our field of view: while you focus on your task the brain is still constantly scanning the "peripheral" imagery your eyes record for possible "occurences" (like possible threats > escape reflex).But that's not what I'm trying to get at:
With a semi transparent screen the gfx people will have a hard time designing the game as they clearly need to seperate the graphical content of the game from the real world. Best examples are icons > try to view icons with different backgrounds and see how on some backgrounds the icons partially start to "merge" with the background depending on which color the icon and the background have in a particular spot. While this usually can be avoided by either altering parts of the background or the icon, this is getting really hard in your vision as you can't change the color of the game nor the colorscheme of the particular part of the real world you currently are.
Going back to the video: its rather easy in that video to accomplish the task as everthing is distinguishable regarding the color, you have players with white shirts, black shirts and a red ball (and even the monkey costume isn't colored in the same black as some players have on their shirt). Try imagine a white ball and the second team wearing light grey t-shirts, and sometimes the background partially changes from grey to white.
Its hard for me to believe that your brain will always isolate the exact parts of the picture that are part of the game, especially if the game itself uses several layers on which movement can happen.
