The nose knows... how to let quadriplegics move and speak (video)
We've seen quadriplegic transportation directed by brainwaves, speech and even the occasional Wiimote, but your best bet might be to follow your nose. Israeli nasal researchers at the Weizmann Institute of Science unveiled a "sniff controller" this week, that measures nasal pressure to control a wheelchair joystick with surprising precision (see a video after the break) and a specially-developed typing interface. The latter is likely the more important advancement, as Discover heartwarmingly reports at the source link, by giving patients with locked-in syndrome (a la The Diving Bell and the Butterfly) the long-lost ability to speak. Best of all, the technology is inexpensive compared to alternatives on the market; while a Stephen Hawking-esque eye-tracking system can cost tens of thousands of dollars, Weizmann scholars reportedly pieced the prototype together for $358. The device is already being considered for public availability by the institute's technology transfer company, Yeda R&D -- find out just how it works in the full study at our more coverage link.
MICRODIA's Fruity USB flash drives: now in four great scents
While not nearly as lavish as Debreu's Scent Drive, MICRODIA is delivering its own set of scented flash drives for those who just can't keep their USB storage away from those nostrils. Reportedly, the USB 2.0 Fruity Flash Keys will arrive in four different flavors, so those who tend to prefer strawberry, grape, green apple, or (Engadget's personal favorite) orange should be thrilled by the selection. Each drive will supposedly be available in sizes ranging from a mere 128MB to 4GB, and while pricing and availability details aren't yet available, we'll keep our nose to the ground for any future information.[Via Gearlog]
Researchers catch a whiff of "aroma fingerprints"
While we've already seen just how savvy dogs are at scouting out cellphones, researchers around the globe have teamed up to find out how pups distinguish the aromas that each individual emits, and the result is a highly influential electronic nose. Now if the boys in blue can't track you down via fingerprint, EEG signatures, or just looking at those guilt-filled eyes, it looks like your "aroma fingerprint" just might find you out anyway. The team has uncovered that each human has at least 44 chemical compounds in their odors that can be distinguished, and aside from assisting in identification, can be used in forensic studies to determine true causes behind crimes, deaths, or other misdemeanors. It's even stated that this new technique can assist officials in learning about one's "gender, lifestyle, whether or not they smoke, recent meals, and stress levels." Of course, criminals could be shaking in their boots, but until the scientists find a way to sniff through "deodorant and perfume," we can't exactly count on this being reliable.[Via Spluch]
