#Algorithms could adjust screens to your vision University of California Berkeley Original Studyposted by Sarah Yang-Berkeley on August 15 2014.
Researchers are developing vision-correcting displays for computer monitors that would let people see text and images clearly without their glasses or contact lenses.
The technology could potentially help hundreds of millions of people who currently need corrective lenses to use their smartphones tablets and computers.
More importantly the displays could one day aid people with more complex visual problems known as high order aberrations

The setup adds a printed pinhole screen sandwiched between two layers of clear plastic to an ipod display to enhance image sharpness.

This latest approach improves upon earlier versions of vision-correcting displays that resulted in low-contrast images.
The new display combines light field display optics with novel algorithms. Huang now a software engineer at Microsoft corp. in Seattle notes that the research prototype could easily be developed into a thin screen protector
and that continued improvements in eye-tracking technology would make it easier for the displays to adapt to the position of the user s head position. n the future we also hope to extend this application to multi-way correction on a shared display
so users with different visual problems can view the same screen and see a sharp imagesays Huang.

#Patients tell more secrets to virtual humans Patients are more willing to disclose personal information to virtual humans than to actual ones,
likely because computers don make judgments or look down on people the way another human might.
The study provides the first empirical evidence that virtual humans can increase a patient willingness to disclose personal information in a clinical setting.
It also presents compelling reasons for doctors to start using virtual humans as medical screeners. The honest answers acquired by a virtual human could help doctors diagnose
Virtual humans For the study, which will appear in Computers in Human Behavior, researchers recruited 239 adults through Craigslist.

Their HICANN chiphort for High Input Count Analog Neural Networkould be the core of a system designed to accelerate brain simulations
with a roadmap to greatly expand that hardware base. Each of these research teams has made different technical choices,
such as whether to dedicate each hardware circuit to modeling a single neural element (e g.,, a single synapse) or several (e g.,

With that cheaper hardware and compiler software to make it easy to configure, these neuromorphic systems could find numerous applications.

but you are not trying to be perfect. owever today s computers are designed to compute precise results even
Approximate computing could endow computers with a capability similar to the human brain s ability to scale the degree of accuracy needed for a given task.
but computer software and hardware are not like that. They often compute to the same level of accuracy all the time. urdue researchers have developed a range of hardware techniques to demonstrate approximate computing showing a potential for improvements in energy efficiency.

#3d-printed loudspeaker plays Obama speech The first 3d-printed consumer electronic is a loudspeaker that comes out of the printer ready to use.
It s an achievement that 3d printing evangelists feel will soon be the norm; rather than assembling consumer products from parts and components complete functioning products could be fabricated at once on demand. verything is 3d printedsays Apoorva Kiran as he launched a demo by connecting the newly printed mini speaker to amplifier wires.
For the demo the amplifier played a clip from President Barack Obama s State of the Union speech that mentioned 3d printing.

Most printers cannot efficiently handle multiple materials. It s also difficult to find mutually compatible materialsâ##for example conductive copper

#Computer gets smarter by looking at online pics 24-7 Carnegie mellon University Posted by Byron Spice-Carnegie mellon on November 26 2013a computer program called the Never Ending Image Learner (NEIL) is running 24
As NEIL s visual database grows the computer program gains common sense on a massive scale. NEIL leverages recent advances in computer vision that enable computer programs to identify
and label objects in images to characterize scenes and to recognize attributes such as colors lighting and materials all with a minimum of human supervision.
In turn the data it generates will further enhance the ability of computers to understand the visual world
and with NEIL we hope that computers will do so as well. computer cluster has been running the NEIL program
since late July and already has analyzed three million images identifying 1500 types of objects in half a million images and 1200 types of scenes in hundreds of thousands of images.

Dendrites effectively act as mini-neural computers actively processing neuronal input signals themselves. Directly demonstrating this required a series of intricate experiments that took years
They used patch-clamp electrophysiology to attach a microscopic glass pipette electrode filled with a physiological solution to a neuronal dendrite in the brain of a mouse.
