Computers will someday soon automatically provide short video digests of a day in your life, your family vacation or an eight-hour police patrol, say computer scientists at the Univ. of Texas at Austin. The researchers are working to develop tools to help make sense of the vast quantities of video that are going to be produced by wearable camera technology such as Google Glass and Looxcie.
From Sept. 16 to 18, 2013, top leaders from the White House and U.S. science agencies and their international colleagues will gather for three days in Washington, D.C., for a major meeting of the Research Data Alliance (RDA). More than 850 researchers and data experts belong to the RDA, which focuses on the development and adoption of common tools, harmonized standards and infrastructure needed for data sharing by researchers.
During this week’s Intel Developer Forum, new Intel CEO Brian Krzanich announced a number of near-term changes for the company’s product line, including new LTE and 14-nm products, and a lower-power product family called Quark directed at future wearable electronics devices.
Those separated from family and friends by long distances often use video conferencing services such as Skype in order to see each other when talking. But who hasn’t experienced the frustration of your counterpart not making direct eye contact during the conversation? A software prototype from the laboratories ETH Zurich may be able to help by leveraging the color and depth information made available by XBox Kinect cameras.
The combined computing power of 200,000 private PCs helps astronomers take an inventory of the Milky Way. The Einstein@Home project connects home and office PCs of volunteers from around the world to a global supercomputer. Using this computer cloud, an international team analyzed archival data to discover 24 pulsars which has been previously missed by astronomers.
Data can be a challenge for many scientists, including entomologists. From bumblebees to blister beetles, the world-class Univ. of Kansas entomology collection numbers 5 million insects pinned in drawers, each one with a tiny printed or handwritten label. A web-accessible and searchable database called Specify has been implemented to help digitize this massive collection.
Univ. of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher. Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other side of campus, causing Stocco’s finger to move on a keyboard.
Google Glass is designed to work like a smartphone that's worn like a pair of glasses. Although it looks like a prop from a science fiction movie, the device is capturing imaginations beyond the realm of nerds. Some 10,000 people are trying out an early version of Glass, most of them selected as part of a contest. Their feedback reveals some advantages and shortcomings of the technology.
Now that the Internet’s basic protocols are more than 30 years old, network scientists are increasingly turning their attention to ad hoc networks where unsolved problems still abound. Most theoretical analyses of ad hoc networks have assumed that the communications links within the network are stable. But that often isn’t the case with real-world wireless devices.
