Integrating Temporality and Causality to the Design of Interactive Systems


Contact: Mathieu Nancel | email | webpage

The project addresses a fundamental limitation in the way interfaces and interactions are designed and even thought about today, an issue we call procedural information loss: once a task has been completed by a computer, significant information that was used or produced while processing it is rendered inaccessible regardless of the multiple other purposes it could serve. It hampers the identification and solving of identifiable usability issues, as well as the development of new and beneficial interaction paradigms. We will explore, develop, and promote finer granularity and better-described connections between the causes of those changes, their context, their consequences, and their timing. We will apply it:
