A cognitive psychologist (John Flach) and an industrial design engineer (Fred) draw from their experiences trying to make technology work for people to reflect on the foundations of Cognitive Science and Product Design, inspired by Pirsig’s Metaphysics of Quality described in Zen and the Art of Motorcycle Maintenance. This book takes the reader on a journey beyond ‘information processing’ and the computer metaphor, toward ‘meaning creation’ as inspired by recent discoveries in dynamics and selforganizing systems, beyond the conventional dichotomy of mind and matter to explore a world of ‘what matters’.

On viewpoint parallax for Medical surgery / Laparoscopy. This thesis explores the Delft Virtual Window System [DVWS, App. I, Smets 1995b, Overbeeke et al. 1988, using viewpoint parallax to create 3D/provide spatial information] for laparoscopy aiming to restore perception/action coupling for the surgeon. It describes the design of an instrument (robot arm) that provides the surgeon with direct control over the laparoscope during operation, and through the restored perception/action coupling allows for better spatial awareness.

The working prototype was successfully tested in a practical setting demonstrating the surgeon’s ability to perform an operation without needing assistance to operate the laparoscope.
