Trajectories: a conceptual framework for complex user experiences

 

 

Artists working at the cutting edge of interactive experience design are creating new kinds of user experience that embed computers into extended physical sets and timescales and that address multiple performance roles. These kinds of novel experience may provide glimpses of future more mainstream cultural applications.

 

Trajectories is a new conceptual framework that captures the idea of establishing a coherent journey through an extended experience that combines many different spaces, times, roles and interfaces. Trajectories involve different kinds of transitions and traversals that may occur throughout an experience. Canonical and participant trajectories capture the tension between pre-scripted narrative and interactivity. Diverging, converging and crossing trajectories reflect important aspects of multi-user experiences.

 

The trajectories framework has emerged from reflections on more than ten years experience of collaborating with artists, most notably Blast Theory, to create, tour and study a series of interactive artworks and performances. It is also driven by an interdisciplinary collaboration with Gabriella Giannachi from Drama Studies at Exeter University.

 

The framework aims to provide sensitizing concepts to guide empirical studies, provide a structure for distilling craft design knowledge, identify requirements for new technologies, and ultimately underpin a new dramaturgy of interactive performance.

 

A full account of the trajectories framework will be published in the book Performing Mixed Reality (Benford and Giannachi) by MIT Press in July 2011.

 

I am also able to run a full-day workshop on applying the framework to different kinds of experience, using a format that was first run at the 2020 Digital Futures conference.
