The chairman and CEO of the world's largest search engine is urging college graduates to turn off their computers and discover the humanity around them.

Google's Eric Schmidt spoke at the University of Pennsylvania's commencement ceremony in Philadelphia on Monday.

The Class of 2009 is graduating in a tough economic climate, but Schmidt says such downturns can be a time for innovation.

He noted that Rice Krispies, Twinkies and beer cans were all products of the Great Depression — and staples of college life.

Schmidt says that while graduates can't plan for innovation or inspiration, they can be ready for it when it happens.
