Cloud computing has arisen as the in-vogue description for the massive aggregation of a wide variety of IT services delivered via fast digital networks — much like power generation and the electrical grid of a public utility. The idea is not new. In fact, the concept of today's cloud computing may date back to 1961, when John McCarthy, retired Stanford professor and Turing Award winner, delivered a speech at MIT's Centennial. In that speech, he predicted that in the future, computing would become a "public utility."1 Yet for colleges and universities, the recent growth of pervasive, very high speed digital networks offers not simply access to more efficient computing but rather a new capability and an opportunity to rethink approaches for delivering IT services. - Alan Levine

The worldwide economy has jolted all of us to attention, while our public and private institutions are faced with budget-cuts, hiring freezes, and uncertainty. As we know, education has always been our country's source of new ideas and wealth creation. That's why it's more important than ever that we address unmet needs in education. Come be a part of the process of supercharging education during these tough times! The inaugural Big Ideas Fest is the starting point for a movement that supports innovation in education at a time when the need to accelerate high-quality learning is truly essential for our country and our future. The goal of this unique three-day meeting of experts and creative doers and thinkers is to spotlight, challenge and change the ways in which education can be made relevant to learning in the post-industrial world. The goal is to increase relevance of education while placing learning at the front and center of all that we do - Alan Levine

The Hand Gesture Interface is a real time gestural interface based on 3D dynamic hand gesture recognition using simple webcams. The application captures and recognizes hand gestures of the user wearing colored gloves, where the hand coordinates are obtained via 3D reconstruction from stereo. The developed system aims to be a generic interface for Windows based applications, and provides supplementary features such as an interactive training and gesture defining system, a gesture tutor, a self-calibration utility for the cameras and a tool for linking the interface to different applications. The interface can be used by people with disabilities for various tasks, as well as by common users for controlling of desktop applications. The system can be linked to any third party program through generation of windows based mouse and keyboard events. - Alan Levine

Atlas Gloves is a DIY physical interface for controlling 3D mapping applications like Google Earth. The user interface is a pair of illuminating gloves that can be used to track intuitive hand gestures like grabbing, pulling, reaching and rotating. The Open Source Atlas Gloves application can be downloaded here and operated from home using a webcam and two self-made illuminating gloves (or flashlights). - Alan Levine

Thinking tools are typically designed for students working on their own computers. When used from the front of a classroom, the complex graphical user interfaces of these tools can interfere with an instructor’s ability to lecture effectively and to use natural gestures. A thinking tool for the grade 9 mathematics topic of “relationships” has been developed with a more gesture-friendly interface. This gesture-friendly interface allows a teacher to focus more on interacting with students, creating engaging visualizations, and using natural hand and arm gestures as part of the lecture. - Alan Levine

Gesture recognition is becoming a more common interaction tool in the fields of ubiquitous and wearable computing. Designing a system to perform gesture recognition, however, can be a cumbersome task. Hidden Markov models (HMMs), a pattern recognition technique commonly used in speech recognition, can be used for recognizing certain classes of gestures. Existing HMM toolkits for speech recognition can be adapted to perform gesture recognition, but doing so requires significant knowledge of the speech recognition literature and its relation to gesture recognition. Thus, we introduce the Georgia Tech Gesture Toolkit (GT2k), which leverages Cambridge University's speech recognition toolkit, HTK, to provide tools that support gesture recognition research. GT2k provides capabilities for training models and allows for both real-time and off-line recognition. - Alan Levine

90% of deaf children are born to hearing parents. Most do not know sign language or have low levels of proficiency. Unlike hearing children of English-speaking parents or deaf children of signing parents, these children often lack the serendipitous access to language at home which is necessary in developing linguistic skills during the "critical period" of language development. Often these children's only exposure to language is from signing at school. Castle Quest and CopyCat are games that use our sign language recognition system to augment early classroom teaching for developing American Sign Language (ASL) skills in young deaf children. - Alan Levine

The enterprise notebook space is much more interesting now that Dell has announced the Latitude Z. The Z is a 16-inch ultra-thin “preppy” notebook with some firsts for the the industry. Dell has outfitted the Latitude Z with the first wireless charging option for a notebook. That’s not all though, they’ve also made an option for wireless docking in an attempt to leave the Z totally untethered in the office. - Alan Levine

Earlier this week, people in Mexico and the US recognized Dia De Muertos (Day of the Dead), a holiday which recognizes friends and loved ones which have recently departed. So this week we have decided to recognize some technologies which have recently or will soon be leaving the technology mainstream. Unlike other recent lists, this was fairly easy to construct and there was limited, if occasionally spirited (no pun intended), debate about its order. - Alan Levine

At the recent Intel Developer Forum (IDF), I demonstrated a technology developed at our research lab in Seattle that relies on strongly coupled resonators to wirelessly transmit power for several feet with great efficiency. In the month since IDF, the feedback on wireless power transmission has been extraordinary. Clearly the prospect of cutting cords seems to resonate with people everywhere. Someone (not Intel!) has already created a Wikipedia entry for it. - Alan Levine

The hype cycle around wireless power has been gathering a charge ever since Intel wowed folks at its IDF conference last year with a demo of wireless charging. Then over the summer, a TED video surfaced with a similar demo, starring the CEO of WiTricity. And this week we saw Dell launch a notebook with wireless charging and Nokia join a new industry consortium dedicated to wireless power. But like other aspects of the wireless world, there are a lot of differences, issues and things that average outlet-avoiding consumer needs to know - Alan Levine

Soljačić started searching for ways to transmit power wirelessly. Instead of pursuing a long-distance scheme like Tesla's, he decided to look for midrange power transmission methods that could charge--or even power--portabl­e devices such as cell phones, PDAs, and laptops. He considered using radio waves, which effectively send information through the air, but found that most of their energy would be lost in space. More-targeted methods like lasers require a clear line of sight--and could have harmful effects on anything in their way. So Soljačić sought a method that was both efficient--able to directly power receivers without dissipating energy to the surrounding­s--and safe. He eventually landed on the phenome­non of resonant coupling, in which two objects tuned to the same frequency exchange energy strongly but interact only weakly with other objects. - Alan Levine

A system that can deliver power to devices without the need for wires has been shown off at a hi-tech conference. The technique exploits simple physics and can be used to charge a range of electronic devices over many metres. Eric Giler, chief executive of US firm Witricity, showed mobile phones and televisions charging wirelessly at the TED Global conference in Oxford. He said the system could replace the miles of expensive power cables and billions of disposable batteries. - Alan Levine
