Vitruvius, the first Roman Architect to write about architecture, asserted that any well-designed building must exhibit the three qualities of firmitas, utilitas, and venustas or be durable, useful and beautiful. Can these same three tenets be applied today to help us design better interactions in a digital environment? This presentation will first touch on the similarities between designing buildings and designing digital interactions. Then, there will be an introduction to Vitruvius and his book, De Architectura. In his book Vitruvius writes about this notion of a well-designed building being durable, useful and beautiful. Those three qualities will first be looked at in their historical context, but then will be examined to see how they translate into the contemporary context of interaction design.
