“Learning should take place when it is needed, when the learner is interested, not according to some arbitrary, fixed schedule”

“Will robot teachers replace human teachers? No, but they can complement them. Moreover, the could be sufficient in situations where there is no alternative––to enable learning while traveling, or while in remote locations, or when one wishes to study a topic for which there is not easy access to teachers. Robot teachers will help make lifelong learning a practicality. They can make it possible to learn no matter where one is in the world, no matter the time of day. Learning should take place when it is needed, when the learner is interested, not according to some arbitrary, fixed schedule”

“Any time you see signs or labels added to a device, it is an indication of bad design: a simple lock should not require instructions.”

“Principles of design:1. Use both knowledge in the world and knowledge in the head.2. Simplify the structure of tasks.3. Make things visible: bridge gulfs between Execution and Evaluation.4. Get the mappings right.5. Exploit the power of constraints.6. Design for error.7. When all else fails, standardize.”

“Forget the complaints against complexity; instead, complain about confusion.”

“Simplification is as much in the mind as it is in the device.”

“Design is really an act of communication, which means having a deep understanding of the person with whom the designer is communicating.”
