Who is Jefferson Han?

Jefferson Y. Han is a research scientist for New York University's Courant Institute of Mathematical Sciences, and one of the main developers of "multi-touch sensing", which unlike older touch-screen interfaces was able to recognize multiple points of contact.

Jeff Han also works on other projects in the fields of autonomous robot navigation, motion capture, real-time computer graphics, and human-computer interaction.

He presented his multi-touch sensing work in February 2006 at the TED Conference in Monterey, California. TED released the video online 6 months later and it spread quickly on YouTube.

Han has founded a company called Perceptive Pixel to develop his touch screen technology further, and he has already shipped touch screens to parts of the military. Han's technology has been featured most notably as the "Magic Wall" on CNN's Election Center coverage. Han's company was acquired by Microsoft in 2012, where he remains General Manager of Perceptive Pixel hardware.

He is the son of middle-class Korean immigrants who emigrated to America in the 1970s.
