This demo — from Pattie Maes’ lab at MIT, spearheaded by Pranav Mistry — was the buzz of TED. It’s a wearable device with a projector that paves the way for profound interaction with our environment. Imagine “Minority Report” and then some

Pattie Maes was the key architect behind what was once called “collaborative filtering” and has become a key to Web 2.0: the immense engine of recommendations — or “things like this” — fueled by other users.

Pranav Mistry is a PhD student in the Fluid Interfaces Group at MIT’s Media Lab. Before his studies at MIT, he worked with Microsoft as a UX researcher. Mistry is passionate about integrating the digital informational experience with our real-world interactions.

Speaking at LIFT 2007, Sugata Mitra talks about his Hole in the Wall project. Young kids in this project figured out how to use a PC on their own — and then taught other kids. He asks, what else can children teach themselves?

In 1999, Sugata Mitra and his colleagues dug a hole in a wall bordering an urban slum in New Delhi, installed an Internet-connected PC, and left it there (with a hidden camera filming the area). What they saw was kids from the slum playing around with the computer and in the process learning how to use it and how to go online, and then teaching each other.

In the following years they replicated the experiment in other parts of India, urban and rural, with similar results, challenging some of the key assumptions of formal education. The “Hole in the Wall” project demonstrates that, even in the absence of any direct input from a teacher, an environment that stimulates curiosity can cause learning through self-instruction and peer-shared knowledge. Mitra, who’s now a professor of educational technology at Newcastle University (UK), calls it “minimally invasive education.”

Researcher Kamal Meattle shows how an arrangement of three common houseplants, used in specific spots in a home or office building, can result in measurably cleaner indoor air.

Kamal Meattle has a vision to reshape commercial building in India using principles of green architecture and sustainable upkeep (including an air-cleaning system that involves massive banks of plants instead of massive banks of HVAC equipment). He started the Paharpur Business Centre and Software Technology Incubator Park (PBC-STIP), in New Delhi, in 1990 to provide “instant office” space to technology companies. PBC-STIP’s website publishes its air quality index every day, and tracks its compliance to the 10 principles of the UN Global Compact, a corporate-citizenship initiative.

Meattle has long been a environmental activist in India. In the 1980s he helped India’s apple industry develop less-wasteful packaging to help save acres of trees. He then began a campaign to help India’s millions of scooter drivers use less oil. His next plan is to develop a larger version of PBC-STIP, making a green office accessible to more businesses in New Delhi and serving as an example of low-cost, low-energy office life.

Many people think the lines on the map no longer matter, but Parag Khanna says they do. Using maps of the past and present, he explains the root causes of border conflicts worldwide and proposes simple yet cunning solutions for each.

Political scientist Parag Khanna travels the world with his eyes open — and has become a trenchant critic of the standard wisdom about the second and third worlds. Khanna’s recent book, The Second World: How Emerging Powers Are Redefining Global Competition in the Twenty-first Century, looks at the epic political manipulations of nations struggling to end up at the top of the global heap. Esquire calls Khanna one of the 75 people who will influence the 21st century, precisely because it’s these smaller countries that will shape the world’s future.

Khanna argues that we’re entering a time of apolarity — when the traditional centers of gravity (US/Europe/Russia/China) will no longer hold. He sees a 21st century that has much in common with the feudal 16th century, where non-state actors have as much influence on the course of world events as countries do. His next book will explore this new medievalism and its effect on the diplomatic-industrial complex.

Al Gore presents evidence that the pace of climate change may be even worse than scientists recently predicted.He challenges us to act.

He was awarded the Nobel Peace Prize for 2007, along with the Intergovernmental Panel on Climate Change (IPCC), “for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change.” full bio and more links

Vilayanur Ramachandran tells us what brain damage can reveal about the connection between celebral tissue and the mind, using three startling delusions as examples.

V.S. Ramachandran is a mesmerizing speaker, able to concretely and simply describe the most complicated inner workings of the brain. His investigations into phantom limb pain, synesthesia and other brain disorders allow him to explore (and begin to answer) the most basic philosophical questions about the nature of self and human consciousness.

Ramachandran is the director of the Center for Brain and Cognition at the University of California, San Diego, and an adjunct professor at the Salk Institute. He is the author of Phantoms in the Brain, the basis for a Nova special, and A Brief Tour of Human Consciousness; his next book, due out in January 2008, is called The Man with the Phantom Twin: Adventures in the Neuroscience of the Human Brain
