BrainBank: A Nose That Can See is Worth Two That Sniff Edition

Yes, there are a good few ways of letting quadriplegics and other sorts of paralyzed people communicate in this modern day and age, but rarely have we found something so commercially viable as this. The prototype for this device, which measures nasal pressure to allow from anything from controlling a wheelchair joystick to spelling out words, cost a completely affordable $358 to produce.

In comparison, Steven Hawking's eye-tracking system costs upwards of tens of thousands of dollars.

Pretty awesome that something so integral to improving quality-of-life for paralyzed individuals could finally be so commercially viable.
