Jefferson Y. "Jeff" Han (born 1975) is an American computer scientist who worked forNew York University's (NYU)Courant Institute of Mathematical Sciences until 2006. He is one of the main developers of "multi-touch sensing", which, unlike oldertouch-screen interfaces, is able to recognize multiple points of contact.
Han also works on other projects in the fields ofautonomous 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 (Technology Entertainment Design) Conference in Monterey, California. TED released the video online six months later and it spread quickly onYouTube.[1]
Han founded a company calledPerceptive Pixel to develop his touch screen technology further, and he has already shipped touch screens to parts of the military.[2] Han's technology has been featured most notably as the "Magic Wall" onCNN's Election Center coverage.[3] Han's company was acquired byMicrosoft in 2012, where he became Partner General Manager of Perceptive Pixel (laterSurface Hub). Han left Microsoft in late 2015, shortly before Surface Hub's launch.[4]
He is the son of middle-class Korean immigrants who emigrated to the United States in the 1970s.
Han graduated fromThe Dalton School in New York in 1993 and studiedcomputer science andelectrical engineering for three years atCornell University before leaving to join a start-up company to commercialize theCU-SeeMe video-conferencing software that he helped develop while an undergraduate at Cornell.[2]
Han was named toTime magazine's 2008 listing of the "100 Most Influential People in The World".[5]
