'''Jefferson Y. "Jeff" Han''' (born 1975) is an American computer scientist who worked for [[New York University]]'s (NYU) [[Courant Institute of Mathematical Sciences]] until 2006. He is one of the main developers of "[[Multi-touch|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 ([[Technology Entertainment Design]]) Conference in Monterey, California. TED released the video online six months later and it spread quickly on [[YouTube]].<ref>{{YouTube|QKh1Rv0PlOQ|Jeff Han on TED Talks }}</ref>
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.<ref name=FCFEB2007>[http://www.fastcompany.com/subscr/112/open_features-canttouchthis.html Can't Touch This] {{Webarchive|url=https://web.archive.org/web/20070825121750/http://www.fastcompany.com/subscr/112/open_features-canttouchthis.html |date=2007-08-25 }} Fast Company, February 2007</ref> Han's technology has been featured most notably as the "[[Multi-Touch Collaboration Wall|Magic Wall]]" on [[CNN]]'s Election Center coverage.<ref>{{cite web |url=http://broadcastengineering.com/newsrooms/cnn_clarifies_complex_caucus/ |title=CNN clarifies complex caucus cavalcade with new 'Magic Wall' |accessdate=2008-03-03 |date=January 4, 2008 |work=BroadcastEngineering |url-status=dead |archiveurl=https://web.archive.org/web/20080221014655/http://broadcastengineering.com/newsrooms/cnn_clarifies_complex_caucus/ |archivedate=February 21, 2008 }}</ref> Han's company was acquired by [[Microsoft]] in 2012, where he became Partner General Manager of Perceptive Pixel (later [[Surface Hub]]). Han left Microsoft in late 2015, shortly before Surface Hub's launch.<ref>{{cite web |url=https://www.zdnet.com/article/microsoft-surface-hub-chief-holoportation-researchers-leave-to-form-stealth-startup/ |title=Microsoft Surface Hub chief, Holoportation researchers leave to form stealth startup |website=[[ZDNet]] |access-date=2016-12-14 }}</ref>
==Personal life== He is the son of middle-class Korean immigrants who emigrated to the United States in the 1970s.
==Education== Han originally attended the Osmond A. Church Public Elementary School in [[South Ozone Park]] [[Queens]]. He later graduated from [[The Dalton School]] in [[Manhattan]] in 1993 and studied [[computer science]] and [[electrical engineering]] for three years at [[Cornell University]] before leaving to join a start-up company to commercialize the [[CU-SeeMe]] video-conferencing software that he helped develop while an undergraduate at Cornell.<ref name=FCFEB2007 />
==Honors== Han was named to ''Time'' magazine's 2008 listing of the "100 Most Influential People in The World".<ref name=time100>{{cite magazine |url=http://www.time.com/time/specials/2007/article/0,28804,1733748_1733754_1735325,00.html |archive-url=https://web.archive.org/web/20080503105754/http://www.time.com/time/specials/2007/article/0,28804,1733748_1733754_1735325,00.html |url-status=dead |archive-date=May 3, 2008 |title=Jeff Han – The 2008 TIME 100 – TIME |magazine=Time |date=2009-04-30 |accessdate=2010-05-06}}</ref>
