IN December, Johnny Chung Lee, then a Ph.D. candidate, posted a five-minute video on YouTube that became an Internet sensation.

The video showed how, in a few easy steps, the Nintendo Wii remote controller  or “Wiimote”  could transform a normal video screen into a virtual reality display, with graphics that seemed to pop through the screen and into the living room. So far, the video has been seen more than six million times.

That video, together with others that Mr. Lee, now 28, posted on YouTube, have drawn people to the innovator as well as his innovations. Video game companies have contacted him and, in September, M.I.T.’s Technology Review named him as one of its top innovators under 35.

When he completed his degree this year at the Human-Computer Interaction Institute of Carnegie Mellon, he received “lots of offers from all the big places,” according to Paul Dietz, who convinced Mr. Lee to join him in the applied sciences group of Microsoft’s entertainment and devices division. “When we told Bill Gates we were trying to recruit Johnny, he already knew about his work and was anxious to bring him to Microsoft,” adds Mr. Dietz, a research and development program manager.
