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.

Video Screen Changes Ads Based On Eye Movement

What's the Latest Development?

Researchers at Lancaster University have developed a video advertising system called Sideways that can change the ads it displays based on the eye movements of shoppers passing by. Senior researcher Andreas Bulling says the system uses a single camera to "[detect] the faces of people walking by and [calculate] where the eyes are relative to the eye corners." Unlike similar systems designed to respond to biometric data, which have to be calibrated to an individual, Sideways can track the gazes of up to 14 people simultaneously. Bulling says, "Calibration is a major stumbling block for interactive gaze-based applications...it's time-consuming and annoying."

What's the Big Idea?

Sideways is the latest system to incorporate eye-tracking technology, bringing video advertising screens alongside other electronic devices such as televisions and smartphones. It'll be a few years before Sideways finds its way into stores, during which time concerns about privacy will hopefully be worked out, says Bulling: "If the system is only there to improve the shopping experience, customers will probably be fine with [it]. If it's a more passive monitoring system of gaze-information, so the user is not aware of it, this could really have considerable privacy challenges."
