This course takes both a practical and theoretical approach to introduce the principles, methods and tools for automation design. Automation is pervasive in interactive applications as it can provide high benefits to the users. However, bad designs jeopardize these benefits and induce human errors (e.g. automation surprises). This course will explain how to design automation and how to assess its pros and cons in terms of user-related properties such as usability, user experience, acceptance or trust. Examples are taken from industries that have been embedding automation in their systems for a long time (such as aviation, automotive, satellite ground segments …) and interactive hands-on exercises will explain how to “do it right”. The course surveys the current trends in AI and surveys how this new technology challenges previous automation knowledge.
