Jefferson Han
Jefferson Y. "Jeff" Han is an American computer scientist who worked for New York University's Courant Institute of Mathematical Sciences until 2006. He is one of the main developers of "multi-touch sensing", which, unlike older touch-screen interfaces, is able to recognize multiple points of contact.
Han also works on other projects in the fields of autonomous robot navigation, motion capture, real-time computer graphics, and human-computer interaction.
Career
He presented his multi-touch sensing work in February 2006 at the TED Conference in Monterey, California. TED released the video online six months later and it spread quickly on YouTube.Han 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 became Partner General Manager of Perceptive Pixel. Han left Microsoft in late 2015, shortly before Surface Hub's launch.
