Knock-Based Commands for Linux Laptop
Linked by Amjith Ramanujam on Thu 31st Jul 2008 17:20 UTC, submitted by jmalasko
Hardware, Embedded Systems For the first time, you can hit your computer and get a meaningful response! Knock some sense into your computer with a Hard Drive Active Protection System-aware kernel, an accelerometer-enabled laptop, and a Perl script. Double tap to lock the screen, and knock in your secret code to unlock. Tap the display lid once to move your mp3 player to the next track. The possibilities are endless.

.. but let's not forget the other possibilities either. One hard tap your screen goes into permanent power saving mode. Or how about double smack gives you a forced emergency shutdown, with secure data lockout.

This adds new meaning to the term "rebooting" your computer!

My old Amiga harddrive used to stick, so I had to slap it every so often...

That would of been annoying when it ran dirOpus or newlist... because of gesture technology.

I have an old Pentium-90 whose former hard drive (1 GB) would stick after it'd been sitting for a while. I had to smack the case smartly right in front of the drive to make it boot.

accelerator for gestures

I would really like to see an accelerator for Linux gestures. It would be a great way to set a complex password. Swoosh Up, Down, Counterclockwise, Diagonal, and a Roll Backwards. It would be difficult to guess or break it by trial and error due to the number of possibilities. Cyber gangs might also find it amusing to be able to encrypt files with hand shake gestures using their secret signs.

Your gestures sound like some special combo move from the old SNK arcade fighting games... ;)

The first thing that came to my mind when reading the description was "cool, now we can have Morse code passwords."

But it would stop being cool as soon as you realize your coworkers can hear your passwords. You would need some serious messhugah-ish skills to come with a hard to memorize pass ;)

Ah well, I guess I'll just have to get started adapting cochlear implants to that purpose ;)
