MIT's glasses-free display in smartphone

Fumbling around for your near-vision glasses to read the tablet screen? University researchers may have come up with a way to alleviate that problem.

Scientists at Massachusetts Institute of Technology and University of California, Berkeley, have developed technology that could lead to displays automatically adjusting to a person's far-sighted or myopic impairments.

If the technology is used successfully, users won't need glasses or contact lenses for TVs, e-readers, tablets or other forms of electronic displays.

People spend more time looking at displays than ever before. The benefit of the research is that it in a sense puts glasses into the display itself, says Gordon Wetzstein, a research scientist at the MIT Media Lab.

Glasses are generally worn because of an inability to view images or text at a certain distance and angle, and lenses adjust the light flowing into the eyes to correct vision. The researchers managed to use a 3D display to generate virtual images to adjust for distance and angle, thus reducing the need for glasses or contact lenses.

Visual impairments may differ in left and right eyes; the researchers used a 3D display because it could project different images to each eye. Doing that and simultaneously tailoring pixels to display full-size images was a challenge, but researchers said a novel algorithm resolved the issue.

The research is a further evolution of the technology used for a glasses-free 3D projector, shown by MIT earlier in May.

Researchers used 3D display technology from MIT Media Lab's Camera Culture group.

Researchers will present a paper on the new display technology at the SIGGRAPH conference in Vancouver from Aug. 10 to 14.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
