Computer Program Recognizes Any Language

Computer Program Recognizes Any Language

New technology that allows computers to recognise any language without pre-learning stands to revolutionise automatic speech recognition. If computers are rendered capable of recognising speech it will one day be the norm to give commands by voice rather than via a keyboard. “Speaking” with a mobile phone is already commonplace for many people. The technology […]

Computer-Simulated Knitting Goes Right Down to the Yarn

Computer-Simulated Knitting Goes Right Down to the Yarn

To put clothes on their characters, computer graphic artists usually simulate cloth by creating a thin sheet, then adding some sort of texture. But that doesn’t work for cable-knit sweaters. To make the image realistic, the computer has to simulate the surface right down to the intricate intertwining of yarn. So computer scientists are in […]

Search Technology That Can Gauge Opinion and Predict the Future

Search Technology That Can Gauge Opinion and Predict the Future

Inspired by a system for categorising books proposed by an Indian librarian more than 50 years ago, a team of EU-funded researchers have developed a new kind of internet search that takes into account factors such as opinion, bias, context, time and location. The new technology, which could soon be in use commercially, can display […]

Crowdsourcing: Need an Expert? Try the Crowd

Crowdsourcing: Need an Expert? Try the Crowd

“It’s potentially a new way to do science.” Can a crowd be an expert? Two UVM scientists think the answer is yes. (photo: James Cridland) In 1714, the British government held a contest. They offered a large cash prize to anyone who could solve the vexing “longitude problem” — how to determine a ship’s east/west […]

Writing Graphics Software Gets Much Easier: New Programming Language Yields Code That’s Much Shorter and Clearer — But Also Faster

Writing Graphics Software Gets Much Easier: New Programming Language Yields Code That’s Much Shorter and Clearer — But Also Faster

Image-processing software is a hot commodity: Just look at Instagram, a company built around image processing that Facebook is trying to buy for a billion dollars. Image processing is also going mobile, as more and more people are sending cellphone photos directly to the Web, without transferring them to a computer first. An image undergoing […]

‘Control-Alt-Hack’ Game Lets Players Try Their Hand at Computer Security

‘Control-Alt-Hack’ Game Lets Players Try Their Hand at Computer Security

Do you have what it takes to be an ethical hacker? Can you step into the shoes of a professional paid to outsmart supposedly locked-down systems? Players assume the roles of characters with their own special skills. Game play involves completing missions by rolling the dice, using skills and occasionally pulling something out of a […]

Better Security for Web and Mobile Applications

Better Security for Web and Mobile Applications

A team led by Harvard computer scientists, including two undergraduate students, has developed a new tool that could lead to increased security and enhanced performance for commonly used web and mobile applications. But who checks the checker? Greg Morrisett, Allen B. Cutting Professor of Computer Science, helped develop a rigorous, machine-checked proof. (Photo by Rose […]
