Interface Design

Published in 2024, Interface Design (BIS Publishers) is the first book to propose a classification system for all inputs used across interfaces, helping designers make decisions that will determine how their product fares once it reaches its audience.

More importantly, by putting interfaces at the centre of product definition, Interface Design offers a provocative perspective on the success of designs from companies such as Teenage Engineering and Apple. Finally, our book sketches a future landscape and warns today's designers of the possible disappearance of interaction, and with it, the very notion of human agency.

Beyond the writing, we also created the 150 illustrations that accompany the text.

More than the product itself, the design of its interface is what determines adoption: the GUI (Graphical User Interface) enabled the computer to enter the home and paved the way for the touchscreen, which in turn marked the democratisation of the smartphone.

While technology is neutral, interfaces are not: whether AI represents a danger or an opportunity for humanity is largely a matter of design — and, specifically, interface design.

The next big leap in interface design will be the transition from active interaction (the user presses a button with intent) to prediction (the device acts before the thought has even formed), which will have unfathomable consequences for human agency.
