The Wizard of Oz Method for Designing Machines

Sally Kohn: I'm a real fan of rapid, low effort prototyping in order to improve the design. So along with Abby Jones at Google, I develop this method where you put your imagined dialogue into just a text file. And then I wrote a little piece of software called Say Wizard. It maps all the lines in your dialogue to keys on your keyboards. She says voice is an unbounded input and can be much easier than a screen interface.
