A solution that just creates new problems ...
I just use an icepick on anyone who gets too close.
"She blinded me with ice picks... No, not icepicks, SCIENCE!"
Will nobody speak for the Truffula trees?
Nice. This makes it really easy to snatch someone's laptop and get a nice woolly jumper in the process.
Hmmm, I'll have to work out the pattern for that. Theirs looks like a seriously over-sized sock.
Is that 'garment' some sort of high-tech version of the islamic 'burqa' ? I guess it could be useful to stop others shoulder-surfing your porn.
Looks like she's having the contents of the ancients' database downloaded directly into her brain. :-)
Whole new meaning for "hat hair"
Got me with that one. Coffee on the keyboard and everything.
SECRETS MAN WAS NOT MEANT TO KNOW!
If only the jumper had had a few more sleeves this could have qualified for a squid posting too....
And that's how my bags got stolen at the airport.
limbo makes a good point. One thing that should always be considered with security products is whether they make you more vulnerable to other forms of attack. Anything that reduces your ability to hear or see potential attackers is not good for security.
The only really good potential solution to shoulder-surfing of the screen contents is to have a head based display (which again gives a security issue and gives a lower resolution).
As for watching key-presses, if you are a touch typist you could scrub the key tops, most people can't even read a keyboard if the letters have been scrubbed off. To make it more difficult you could use a different keyboard mapping.
What I found funny is that just last week I saw somebody wearing his hoodie just like this to work on his laptop outside. Of course it wasn't done for privacy. He was trying take advantage of good weather and also work on his computer outside.
Someone call 911-- oh I see... nevermind.
But seriously does it breathe? Am I the only one who thinks it could get pretty stuffy in there? I'd have to use a straw.
KISS like in Keep It Stupid Simple.
Just waiting the Christian Dior version.
Don't even bother erasing the keys. Just type with a Dvorak layout on a standard keyboard. I do that and it seems to throw everyone off when I hit 'G' and 'I' shows up on the screen.
I will say, though, that the woolly for just the keyboard would be useful for cold hands while typing in the winter...
Why bother *erasing* the keycaps? Much easier to just plop a blank sticker on it. That way you can also remove the sticker if you find it difficult using blank keys.
Yeah, works good until the first time you sneeze...
I used to use an army field jacket zipped up and the hood covering the neck hole to darkbag my 35mm camera back in the day. If there was some reason such as film having slipped off the sprocket you could put the camera inside, fold the hood over the neck hole, fold the waist to close that and reach in through the sleeves to open the back of the camera and feel your way through the fix.
about disguising the keys, I touch type and I use wi fi in cafes, with muffin and coffee, that and the fact that I have a cat at home, means that my keyboard would be subject to a lot of crumbs and the electostatic cat hair, except that I often cover the keyboard with saran wrap off the dayold muffin, crumb side out. this does not inhibit typeing except it makes me more aware of the little marks that are on the F and J keys, but the shiny and wrinkled saran wrap makes it very difficult for someone to see the keys from thier angle. and I don't look at them
