This paper identifies a body of HCI research wherein the researchers take part in digitally mediated creative experiences alongside participants. We present our definition and rationale for "self-situated performance research" based on theories in both the HCI and performance literatures. We then analyse four case studies of this type of work, ranging from overtly "performative" staged events to locative audio and public making.

This paper describes three interactive artefacts created for a children's exhibition intended to encourage creativity and allow educational opportunities to emerge naturally through playful exploration. We describe five sensibilities that were used to inform our designs: considering artefacts as resources and scaffolds for imaginative engagement, rewarding extended investment, facilitating requisite unpredictability, encouraging an imaginative orientation to participation, and permitting multiple loci for interaction. Based on observation of how our interactives were used by the public, we discuss how our approach facilitated "open interactions" in a manner that was sensitive to the museum context, favoured a mix of materialities, and manifested a subtle mix of participation and designer autonomy.

We present an experience-based approach to designing a collaborative interactive performance, humanaquarium. Our research explores public interaction with digital technology through the practice-based inquiry of an inter-disciplinary team of interaction designers and musicians. We present a method of designing experience from within, literally situating ourselves within the performance/use space and assuming the roles both of performers and of designers as we develop and refine the humanaquarium project over the course of a year's worth of public performances.
