I was thinking. iSight is high res, high quality, well, someone should make an interpreter for gestures. If anyone's watched the IDEC ISDA video that's on Apple's Multimedia Starter Disk you know what I mean. Just flick your hand for a click, etc. Whaddayathink?

this would be a good idea, if they developed some sort of sign language for common tasks. However it's more needed in Windows...A two finger salute could replace Ctrl-Alt-Del

I think the Windows Ctrl-Alt-Del would be better represented by a one-finger salute.

yeah...do the peace sign v but reverse it to point the other way..... maybe it's just british... i

t means much the same as the one finger salut but maybe worse. As far as i know it was to make fun at the french cause in ye olde days we used to kill alot of french in battles cause we had the best bow men, and bow men used those two fingers to fire the bow. Cause of this if an english man was taken prisoner the french would cut the two fingers off so they couldn't use a bow anymore. Thus the english used to give the two finger salute to the french to say 'haha we still have our fingers'... its been used here as a kind of insult to someone when your annoyed with them ever since.

surely clicking the mouse is easier? it'd be cool if you get your mac to come off standby when you sit infront of it, or to go to sleep when you turn the light off at night - i'm sure the latter could be easily achieved

your diea does open up the scope for games, like that camera thing you can get for the ps2

i had heard about the two finger salute, but had never heard the story behind it. Thanks!

To a further extent, in a future version of iChat AV + iSight, maybe it could pick up sign language, and then AppleTalk could speak back to the other user. Cool no?

I know it won't happen, but it is cool nonetheless.

This wasn't what I was thinking about, but that's another idea. But, what I was actually trying to achieve here was: with a properly aimed iSight it could follow finger movements so you could point and drag your finger in the air, and it would move the mouse. Only then when you moved your hand out of the way to flick it or some motion to click, it would follow that movement? or be smart enough to stop tracking? Also if the tracker can't be made you could program gestures to do very common things. For example, you could wave your hand in front of iSight, and boom, Expose. You could wave your hand down very quickly and boom, the IM you were looking at would close. This actually could go somewhere. Just think, before the PowerPC, nobody dreamed of speech recognition. I don't even have broadband but when that wonderful day comes when I buy my Mac I'm going to get an iSight for this among other things, like a photoblog. Anyway. I just wonder if this is possibile.

possible? probably.

pointless? definately

it'd be a whole lot easier just to use the mouse

This has been tried by some venders already. Strangely it is in the disability world. On the smallest scale there are programs that track eye movements (actually average movement with in a time and range) and others that track gross body movements. C-Net did an article on a program that moved the mouse using a simple webcam, but there were problems when there were indistinct or complicated backgrounds.

The idea is neat, but in efficient, at least for now.

RE: 2 Finger salute

When I was at Davis I met an engineer from England. He corrected my use of gestures.

Imagine hand salutes.
"No, This means sit and spin. This means **** you!"
I may be one of the few Yanks that prefer the 2-finger form. I think it has more force. Secondly, have you ever played rugby. Anybody that thinks "to hell with the pads" and opts for the pain gets my respect.

Which I think summons a tuk-tuk in Thailand- so one person's insult is anotherís call for a cab.

I'm sure they could do that - it would be excellent for teaching, or business presentations, or even movie editing. They would probably have to have some sort of glove for the person to wear that would send a signal through to the iSight which it could process and translate into the movements on screen. Or they could bypass iSight altogether, make the glove Bluetooth, and have a kick-ass gadget.

okay so after hours and days of searching google i found two applications that let you use your hands to gesture actions and control various applications

the first application which seems very cool is found at and is called Gesture!
http://www.ecs.soton.ac.uk/~amrk03r/iGesture/#Actions "hope the link works for you"

and the second is found at
http://atlasgloves.org/ and is called atlas gloves
this can have some programming code changed if anyone knows how to do that to work for applications such as itunes and finder

Isn't that exactly what the PS2's Eyetoy does?

Interprets gestures to interact with games...

I'd rather have a built-in input tablet on my Macbook (Pro)

Yes, and somewhat unreliably, particularly in certain lighting conditions. Unfortunately, I suspect it will be a long time before movements are picked up precisely enough to be accurate enough to use for a computer interface, as opposed to games.

Shame though, because it would be a nice way of working. What about a Wii type controller/mouse, though? Would that be less likely or more likely to cause RSI?
