Would this be useful in remembering our Bitcoin addresses?

Not really. It requires external software, and at that point you're better off using firstbits. Memorizing the seed for your private key, theoretically yes, but practically it's highly insecure because the system has to know what your private key is.

But cant they just put you in front of that game? And then you will give it out without
even knowing it, since you dont know the password...

How does one "hash" this password? If the user only has to "play" within 80% accuracy, then surely the password is stored in the clear Roll Eyes

You don't have to reproduce motions precisely to yield a consistent input…think of it like typing letters on a keyboard…you don't have to hit them squarely in the middle every time to produce the desired letter. You then take the input, hash it with some other data (provided by the software or website) to yield a password of sorts (like passwordmaker.org). Of course, it could also be used to decrypt a private key and sign a transaction.

I just think it would be cool to be able to wave your hands in the air in a certain, repeatable pattern to sign a transaction. Wink

where is the link to the game!?

Thought this would be of interest to people here…

there are probably many other kinds of patterns that the brain would be good at learning…these 3d gesture input devices come to mind (http://www.technologyreview.com/view/428350/the-most-important-new-technology-since-the-smart/) …I can imagine an disconnected device that reads your gesture input, hashes it with a domain name and userid and yields a long password for use in authenticating… the software or website could communicate the the domain/username to the device and the device could communicate the secure, generated password back to the site…that would be the only communication the device was capable of once initialized.
