Famed technologist and futurist Ray Kurzweil is on the record about human-machine intelligence parity: it's going down by 2029, so be prepared to get digital on entirely new levels. Apparently, machines "will have both the hardware and the software to achieve human level artificial intelligence" by then, but even if it's not in the form of meatbag-terminating cyborgs, Kurzweil thinks one future of intelligent machines is on the nano scale, with interfaces to enhance our own physiology and intelligence. Oh sure, this stuff is completely pie in the sky -- but it's still absurdly fun to think of what kinds of crazy crap the 21st century's going to hold.

Even though we've seen a ton of products designed to aid the visually-impaired in their daily lives, technology still has a long way to go before disabled folks are able to enjoy a completely unrestricted lifestyle, which is why inventor/visionary Ray Kurzweil has spent the last quarter-century building devices that make reading easier for the blind. His latest invention, called the K-NFB, is basically a five megapixel digital camera attached to the back of a Windows Mobile 5.0-powered PDA, which is loaded with software that uses optical character recognition and text-to-speech technology to read aloud the words contained in user-captured photos. Once it's called into action, the $4,860 device supplies the operator with an initial "situation report" that attempts to describe whatever's in the camera's field of vision; if the report indicates that the desired text is within range, owners can then choose to snap a photo and listen to the resulting translation. Although the K-NFB is scheduled to be released soon by the UK's Sight & Sound, several technical issues -- most importantly, the software's difficulty in understanding inverted (white-on-black) text -- still have to be ironed out before it's available to the public.
