For severely autistic people, communication is often impossible, leaving them unable to convey what they want or need. But as Lesley Stahl reports, touch-screen apps designed for tablet computers like the iPad are now giving autistic people new ways to express themselves, some for the first time.

The following script is from "Apps for Autism" which aired on Oct. 23, 2011.
