Here is an e-mail from Susan Lider, a spokeswoman for Kepler's bookstore.

Bill Moggridge of Woodside, author of "Designing Interactions," will speak at Kepler's bookstore in Menlo Park at 7:30 p.m. Wednesday, Jan. 31.

Kepler's says he will tell stories of designers who changed the way people use everyday things in the digital era, based on his interviews with the founders of Google, the creator of The Sims, and the inventors and developers of the mouse and the desktop computer.

Mr. Moggridge is a founder of the design firm IDEO, one of the first to integrate the design of software and hardware into the practice of industrial design.

He has been visiting professor in interaction design at the Royal College of Art in London, a lecturer in design at the London Business School, member of the steering committee for the Interaction Design Institute in Ivrea, Italy, and is currently a consulting associate professor in the Joint Program in Design at Stanford University.
