What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

ZeroTouch: The Invisible Touch Screen

May 16, 2011, 11:49 AM

A project, two years in the making, was revealed this week at the Computer Human Interaction conference in B.C. The device created by students from Texas A&M University is called ZeroTouch and looks like an empty picture frame. Don’t let the looks deceive you, though. It is equipped with infrared sensors and embedded LEDs which help translate human movement into computer commands. When a finger or other device is introduced into the invisible plane, the infrared signals sent from LEDs on one part of the frame are blocked from reaching the complementary sensors on the opposite side, which is then interpreted as a touch.

When ZeroTouch is laid flat on a table it can be used as a drawing board, mounted on a computer screen it can be used as touchscreen device (cheaply converting any regular computer), and if hung in the air it can be used as a virtual canvas for painting. Another difference between ZeroTouch and other types of touch screen is that it requires no pressure and according to its creator Jonathan Moeller it tracks 20+ fingers in its current configuration. This makes possible the use of gestures such as pinching and spreading. The team is also working on a three-dimensional device that should allow for hovering and 3-D hand manipulation of virtual objects.
