ABSTRACT
We discuss the design ideal of explicit interaction, which is a way to approach the dimensions of explicitness versus ambience and explicitness versus obtrusiveness in ubiquitous computing. Explicit interaction refers to interaction techniques designed to make actions and intentions visible, understandable and accountable. We introduce three levels of analysis---usability, materialization, and social performance---and present the design of an explicit interaction assembly of devices for rehabilitation after hand surgery. The assembly, intended to support video recording during patient-therapist consultations, is evaluated and we find that it provides superior usability and the potential to improve rehabilitation outcomes through materialization. Moreover, we find that the design of cues to support the social practice in the rehabilitation ward needs to be improved since the assembly allowed for uses unanticipated during the design.

Design and evaluation of proxemics-aware environments to support navigation in large information spaces
CHI EA '13: CHI '13 Extended Abstracts on Human Factors in Computing SystemsIn my research, I explore the use of proxemics in Human-Computer Interaction to design explicit and implicit interaction with knowledge work environments for literature review, reading & writing, or discussion. This paper proposes the employment of ...
Proxemic interaction: designing for a proximity and orientation-aware environment
ITS '10: ACM International Conference on Interactive Tabletops and SurfacesIn the everyday world, much of what we do is dictated by how we interpret spatial relationships, or proxemics. What is surprising is how little proxemics are used to mediate people's interactions with surrounding digital devices. We imagine proxemic ...
Explicit & Implicit Interaction Design for Multi-Focus Visualizations
ITS '14: Proceedings of the Ninth ACM International Conference on Interactive Tabletops and SurfacesMany tasks that have to be performed to analyze data in large visual information spaces require the user to have several foci. This is for example the case for comparing or organizing digital artefacts. In my research, I explore alternative interaction ...
