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.

EyeWriter: Eyetracking Device Empowers Paralyzed Graffiti Artist

What happens when an artist loses his or her creative currency – the capacity for self-expression? That's exactly what happened to legendary Los Angeles graffiti artist Tony Quan, a.k.a. Tempt One, when he was diagnosed with amyotrophic lateral sclerosis, better known as ALS or Lou Gehrig’s disease. As he began to lose use of his arms and legs, ultimately ending up unable to speak or breathe on his own, Tempt retained full mental clarity and, more importantly, a burning desire for artistic expression as strong as it ever was -- a clearly, painfully frustrating paradox.

Now, thanks to a revolutionary eyetracking device dubbed EyeWriter, Tempt can use his eyes – still fully mobile – to draw graffiti.

EyeWriter is an ongoing research project from Graffiti Research Lab, a collective of artists, urban pranksters and hackers who stage multimedia interventions around the world. Many of them were among Tempt's closest friends, which made his diagnosis as much a devastation as it did an inspiration to intervene through innovation. So they mounted a small camera onto a pair of clunky eyeglass frames, and wired it so that the camera captures the pupil of Quan's right eye, inputting it as it glides over a palette of colors and effects. To select a tool or color, he "clicks" by holding his gaze over it for four seconds He “clicks” by pausing his gaze for four seconds over the desired tool, then draws by moving his gaze around the canvas screen. Rather than saving the artwork in traditional JPG or GIF image formats, which have a number of limitations, output is saved in a GML format – Graffiti Markup Language, a new open-source format developed specifically for EyeWriter. Tempt then uploads his work to a server, from which his supporters have pulled it wirelessly to digitally project Tempt One "eyetags" onto everything from high rises in Los Angeles to Tokyo's city halls to the riverbanks of Vienna.

While expensive eyetracking devices have helped other ALS patients, perhaps most famously Stephen Hawking, what makes EyeWriter particularly compelling is that it's an incredibly low-cost technology hack – it's a $50 device – that achieves a great deal yet requires very little.

Zach Lieberman, one of the lead developers on EyeWriter, presented the project at this year's PSFK Conference in New York, noting that the underlying principle of the tool is not one of technology but one of empathy – an effort to practice empathy, rather than sympathy, towards its users. And that is "design for social good" at its best – an enabler of empathy, of humanity at its best and most compassionate.
