[News] Linux Laptops Get 'Knock-based Commands'

,----[ Quote ]
| For the first time, you can hit your computer and get a meaningful
| response! Using Linux and the Hard Drive Active Protection System
| (HDAPS) kernel drivers, you can access the embedded accelerometers on
| Lenovo (formerly IBM) ThinkPads, then process the accelerometer data
| to read specific sequences of "knocking" events -- literally rapping on
| the laptop case with your knuckles -- and run commands based on those
| knocks. 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.
