The bionic eye: Light-curving camera that may help the blind to see
For years, scientists have set their sights on creating bionic eye transplants to help the blind see.
Yesterday they came a step closer after announcing they had made a camera that can reproduce human vision.
American researchers predict it will revolutionise digital photography and video - and one day even give the gift of sight.

New Light Sensor Mimicks Eye for Superior Camera Performance
One of the disadvantages of modern photo cameras is the flat image sensor that converts light into electric signals. Because of its shape, optics must make up for various aberrations that come to light (excuse the pun). Now scientists at Northwestern University and University of Illinois at Urbana-Champaign have developed technology that allows for building curved sensors and accompanying electronics. The technology one day might come in handy for developing artificial retinas or next generation endoscopic devices.

A combination of movement sensors and ultrasound emitters might lead to versatile motion capture systems for controlling computers

Several sensors measuring about 2.5 centimetres on each side are attached to a person's legs and arms. The sensors detect movement in two different ways: accelerometers and gyroscopes measure motion, but ultrasonic beeps are also emitted.

Tiny microphones mounted on the torso pick up these beeps, allowing a laptop computer, carried in a backpack, to calculate the distance to the sensor. The system is similar to, albeit much simpler than, bats' ultrasonic echolocation, and together with the motion sensors provides a more accurate overall picture of body movement. The small backpack also holds the batteries that power the system.
