I'm forgetful…)What is Interaction Design?What are the experiences we have with technological products?How do we create these experiences?And what makes them more or less successful?Sharp, Rogers & PreeceInteraction Design: beyond human-computer interactionInteraction DesignDesigning interactive products to support people in theireveryday and working livesSharp, Rogers and Preece (2002)The design of spaces for human communication and interactionWinograd (1997)Example of bad and good designElevator controls andlabels on the bottom rowall look the same, so it iseasy to push a label bymistake instead of acontrol buttonPeople do not makesame mistake for thelabels and buttons on thetop row.
