A 'smart glass' iris may provide much greater image quality in future smartphones

In a conventional camera lens, the iris consists of a set of overlapping mechanical blades that control the amount of light entering the camera. As efficient as this mechanical system is, it is too bulky and too difficult to miniaturize to be incorporated in smartphones and other compact devices. To address this, a team of researchers has used "smart glass" to create a micro-sized electronic iris that may bring much greater image quality and flexibility to smartphone cameras.  Read More

A fingerprint obtained from a stainless steel surface, using the new technique

Here’s something that they don’t tell you in the TV cop shows: although fingerprints may be present at a crime scene, only about 10 percent of the prints found are of good enough quality for use in court. A group of scientists are working on boosting that percentage, however, through the use of a color-changing film.  Read More

A demo installation shows View Dynamic Glass at various degrees of tint

The lounges and lobbies of San Francisco's W Hotel have taken a turn for the futuristic, incorporating variable tint "dynamic glass" courtesy of California-based start-up View. View Dynamic Glass, as the company calls its particular brand, alters in tint to reduce the amount of heat and light passing through. Tint can be changed on demand (with an iPhone app, if you like, GigaOM reports); or the process can be automated – allowing View to dub its technology an "intelligent glass system."  Read More
