Paper presented at Emergent Interaction Complexity, Dynamics, and Enaction in HCI. A CHI 2021 Workshop held online, 15th May, 2021 https://www.alandix.com/academic/papers/QQ-Emergent2021/ This paper is about the uniquity and importance of qualitative reasoning about quantitative phenomena. From A–B testing and recommender systems to Covid modelling and climate change, numbers and data drive so much of both the work we do within HCI itself and the applications we work on. Sometimes this requires precise calculations, but often decisions or explanations are more qualitative taking into account general tendencies of numeric systems. This is important for our work within HCI when dealing with quantitative data including dynamic systems, and also as we create tools for those teaching, presenting or working with numeric phenomena.

Most organizations have a large digital experience gap, both for customer and employee experiences. The solution is to much more strategically use their assets, including data, IT systems, and people, more effectively to industrialize and scale their experience capabilities. I recently explored both the business imperative for why as well as the means for how to accomplish this in a lunch keynote at the 10th anniversary Cloud Expo in New York City.

Presentation for UDIA National Congress 2014. Imagine a world where the emerging 'Internet of Things' intersects with smart buildings and cities. Today, developers are faced with the rising expectations of people to be better connected and more efficient in their use of technology, yet buildings still remain one of the last bastions for technological change in our modern society. This insightful presentation will shine a torch on a world of possibilities in the use of technology in property and will highlight what lies ahead for those that are prepared to innovate and make a change.

When cities begin to think - What happens when buildings talk back?

Slides or talk given at Universities of Limerick and Leicester in January 2020. more info at: https://alandix.com/deepdigitality/ https://alandix.com/digitalthinking/ In an ACM Interactions column and an Irish HCI keynote I have explored Deep Digitality, an approach to the radical re-imagination of large scale systems of society: manufacturing, healthcare, government and healthcare. Deep Digitality takes the counter-factual premise asking what these systems would be like of digital technology had preceded the industrial revolution, the Medicis or even Hippocrates. Paradoxically, in some of these digital-first scenarios, digital technology is sparse and yet there is clearly a digital mindset at play. It is the kind of thinking that underlies some of the more radical digital apps and products, and builds on the assumptions of a world where computation and sensing are cheap, communication and information are pervasive, and digital fabrication is mainstream. This digital thinking connects with other 'thinkings' (computational, design, management, systems) and but appears distinct – less focused on decomposition and engineering than computational thinking, but more principle rather than process driven than design thinking. I have been trying to distill some of the defining features and heuristic principles of Digital Thinking and this talk captures some of this nascent work in progress.
