Think of Captcha as the first battle in humanity's fight against AI. Over the long term this problem has no solution.

Except by answering captchas, you're helping the machines (first words for books, then numbers for street view, now pictures for classification).

I just hope it also works for pen-tablets, where the "pointer" can suddenly jump from one location to the next when the pen comes near the surface of the tablet.

That and what about those who fill their form with tab navigation ? No mouse involved here. It is just showing off ...

I just tried the one ins0 linked above, and tabbing through, using space to select the checkbox, worked fine.

Captcha isn't the first battle in humanity's fight against AI, its a recent battle in humanity's fight against abusive humans.

Oh, so just program bots to provide a mouse movement toward a form element along a distorted path, and always trigger them through the UI rather than as events. Got it!

Yeah, good luck with that.

http://phantomjs.org/ makes this easy enough to do.

Or the much more common case of touch screens. I'm assuming it's fine - the fine pointer movements are just one aspect of it, and tapping/clicking with a pen are likely to produce small movements anyway (whether or not those movements are suppressed by the driver of whatever device you're using is another matter).

don't know if this works only for me but here is a live example - https://www.google.com/cbk?cb_client=maps_sv.tactile&output=...

I attempted tabbing to the checkbox and pressing spacebar (not moving the mouse at all) and it worked just fine. Impressive. But I guess the tell-all is how secure it is against bots. not how easy it is for humans to get through. For all we know it could just be letting everyone through :P

I'm pretty sure you can just harvest mouse movement information and train a computer to mimic that.
