Here's a robot video that I found interesting:
NAO asks you a series of math questions (addition, subtraction, multiplication, etc...).
The way NAO asks a question is both oral and visual at the same time. NAO writes the equation while saying it.
Then you have two ways to give your answer, which is either based on speech recognition, or on image recognition (pic number).
This application enables two differents experiences, and is promised to be a fun app for both parents and kids.
