MIT's portable 'seeing machine' for the blind enters testing
Many who are legally blind have functional retinas locked behind lenses so clouded they can't see a thing. Doctors can detect this type of ocular defect using a scanning laser opthalmoscope (or SLO), and can even focus an image onto those hidden retinas to allow the blind to see -- temporarily, since a cost of $100,000 and a rather non-portable design means SLO's are only suited for medical offices. We reported back in 2006 on the efforts of MIT's Elizabeth Goldring and colleagues to create a cheaper, portable version, and now a prototype is entering testing. It's comprised of a digital camera (looks like possibly a Lumix DMC-TZ50) mounted to an LED-backlit LCD that is able to focus to a point, penetrating lenses damaged by glaucoma or macular degeneration. No word on when this sort of thing might be generally available, but testing will take place at the Beetham Eye Institute in Boston, so head on over if you want to get some eyes-on time with one of these.[Via tgdaily]
MIT's $4,000 "seeing machine" for the legally blind
MIT's got a new machine in the works that will offer some discrete seeing abilities to the 1.3 million legally blind in the US without the need for invasive retinal implants. Though it's not portable and doesn't (yet) support video feeds, the 12 x 6 x 6-inch "seeing machine" developed by Elizabeth Goldring, a senior fellow at MIT's Center for Advanced Visual Studies, enables users to control virtual 3D environments, view images, or read documents by way of an LED eyepiece that projects images directly onto the retinas of those with limited vision. (An example of what Goldring apparently see is blown up onscreen above.) We assume the consumer application of such a device is only eventual, but for now it remains with at MIT for development, so, um, keep an eye out.
