Now, new research suggests that if we want to carry out artificial computations, all we have to do is literally look around. A researcher has begun to develop a technique to turn our eyes and visual system into a programmable computer.

With the Internet a major form of participating in popular culture and public discourse, that means men's voices are disproportionately heard. Almost two-thirds of men report posting their work online. Only half of women do. When controlling for digital literacy -- whether perceived or actual -- the research shows they post about equally.

But in reality, the creation of robots with these skills remains a major challenge. Researchers are solving this problem by giving a mobile robotic arm the ability to "see" its environment through a digital camera.

The discovery could lead to great advances in the automated identification of online images and, ultimately, provide a basis for computers to see like humans do. Mon, 26 May 2008 20:00:00 EDT http://www.sciencedaily.com/releases/2008/05/080526000936.htm http://www.sciencedaily.com/releases/2008/05/080520214357.htm A major drawback of the latest generation video products and applications has been the complex requirements for coding and decoding signals. An alternative put forward by European researchers turns the traditional video coding paradigm on its head.

Researchers in the United States and Brazil describe development of a simple, inexpensive system that uses cell phone cameras to collect medical data from patients in developing countries for medical analysis by specialists located off-site.

Coli storing images. DNA acting as logic circuits. It's possible, and in some cases, it's already happened. In any event, performing digital signal processing using organic and chemical materials without electrical currents could be the wave of the future. Electrical engineers and computer science specialists describe experiments that perform signal processing with novel materials while stirring the engineering community towards "a possible not-so-electronic future" of digital signal processing.

According to researchers, the design of an accessible system needs to incorporate large letter types and keys, the mother language, and a touch screen and ABCDE keyboard as input devices. Furthermore, positive feedback is important to reduce the stress experienced by pensioners whilst using the computer.

Researchers found the higher the socio-economic status, the greater the time spent on the Web and the more sophisticated the search and evaluation skills. Google was the favored search engine by parents in the high socio-economic group. Tue, 25 Mar 2008 23:00:00 EDT http://www.sciencedaily.com/releases/2008/03/080324201319.htm http://www.sciencedaily.com/releases/2008/03/080319160105.htm Electrical engineers are developing an on-chip imaging sensor with small pixels and 12,616 mini-optic lenses that are created as part of the semiconductor manufacturing process. Used in a digital camera, these lenses will record overlapping views of the scene, creating an electronic "depth map" as well as a photograph. Downloaded to a computer, the map can be used in many ways. The camera technology produces a "depth map" of a scene. The possible uses range from facial recognition to 'in vivo' biological imaging.

As if by magic, images suddenly appear on the display. Their movements follow the actor's gestures, rotate at the slightest turn of a finger, and become larger or smaller as desired. This scene will look familiar to anyone who has watched the science fiction film 'Minority Report'.

Help is on its way in the form of a project called WiMAC(at)home (Wireless Media and Control at Home). In this project, which is being financed by the German Federal Ministry of Economics and Technology (BMWi), researchers are working on the wireless connection of electronic devices for broadcasting and entertainment in home networks.

A survey of 305 students at one campus found that 40 percent of cell phone users said they walked somewhere after dark that they normally wouldn't go. Wed, 05 Mar 2008 17:00:00 EST http://www.sciencedaily.com/releases/2008/03/080303110149.htm http://www.sciencedaily.com/releases/2008/02/080221101910.htm Digital logic, or bits, is the only paradigm for the IT world, and up to now researchers used it almost exclusively to study quantum information processing. But European scientists have proved that an analogue approach is far easier in the quantum world. Modern computing is digital, a series of 1s and 0s that, once combined, create powerful information processing systems. The system is so simple -- on or off, yes or no -- that it almost seems dumb. It is that very simplicity that gives digital computing its power. It works very well. But we have a problem. Silicon circuits are getting so small that they will soon be bumping up against a fundamental physical limit. Tue, 26 Feb 2008 14:00:00 EST http://www.sciencedaily.com/releases/2008/02/080221101910.htm http://www.sciencedaily.com/releases/2008/02/080223125318.htm Researchers have developed an algorithm that is capable of processing 30 images per second to recognize a person's facial expressions in real time and categorize them as one of six prototype expressions: anger, disgust, fear, happiness, sadness and surprise. Applying the facial expression recognition algorithm, the developed prototype is capable of processing a sequence of frontal images of moving faces and recognizing the person's facial expression. The software can be applied to video sequences in realistic situations and can identify the facial expression of a person seated in front of a computer screen. Although still only a prototype, the software is capable of working on a desktop computer or even on a laptop.

The finding could lead to new types of miniature camera lenses, cell phone displays and other microscale fluidic devices. The ability to easily change the contact angle of droplets of nanofluids has potential applications for efficiently moving liquids in microsystems, creating new methods of focusing lenses in miniature cameras, or cooling computer chips.

The results can be used for safe and secure identity control or, on the light side, to find out to which famous persons you look alike. If a non-authorized person gets access to your pin code and credit card, most likely your money will disappear from your account. Nevertheless, this would be impossible if the ATM could recognize your face as you look at a camera. Now, the algorithms to carry out this function, face recognition, exist. Face recognition can also be used in other functions, for instance in a dating service. Maybe the customer is interested in a man that looks like Brad Pitt or a woman that looks like Angelina Jolie.

But the big crowds in small areas put intense strain on mobile networks, causing connection failures and reduced quality of service. Better network resource management offers a low-cost solution. The need for greater network capacity has been a constant concern of mobile operators as mobile phone traffic has increased in recent years and new data services have become available. There are two main ways to meet the demand: invest in costly new infrastructure or improve the way you manage the resources you have.

The steep Martian mesa dubbed "Von Braun" would be a safe haven, the software and data analysis determined -- but the path that Spirit would have to follow to get there is a little too risky to travel with winter on the way.

A novel tabletop touch screen allows hidden sequences of events to be observed in progress. It can be operated intuitively using a combination of fingers and recognizes swiping movements. A crowd of people is gathered around a large table with an illuminated surface, on which images of a journey through pipes and machines in a factory are being displayed. Users can select individual components by touching the corresponding image with a finger. The objects can be rotated and observed by swiping a finger over them -- and the same method can be used to watch a process in slow motion.
