This presentation by Letizia Jaccheri, held during the International Performativity Seminar, delves into the relationship between software and art. With a mini-performance, it explores how software, defined as program code, governs computer behavior. The seminar highlights open-source software examples, research methods in software engineering, and research questions addressing how to enhance knowledge at the intersection of software and art. It emphasizes the potential benefits of their convergence, inviting reflections on technical and aesthetic quality, as well as emotional responses to interactive artifacts.

Research Questions • Research Question: How can we increase knowledge about the intersection between softwareand art? • Question for Practice: How can software benefit from art and vice versa?
Results • a stakeholder model • developers, users, researchers, and artists • a opendocumentationmodel • patchwork of words, still and moving images, music and sound, and digital code • Development or use? • HCI, software engineering • How to evaluate works in this intersection? • Technical and esthetics quality • Are there feelings beyond creativity and amusement we should look at? • Boring, romantic, contemplative, anger, etc.
