"Slurp" Revisited: Using 'system re-presencing' to look back on, encounter, and design with the history of spatial interactivity and locative media

Hand-based gestural interaction in augmented reality (AR) is an increasingly popular mechanism for spatial interactions. However, it presents many challenges. For example, most hand gesture interactions work well for interactions with virtual content and interfaces, but seldom work with physical devices and users environment. To explore this, and rather than inventing new paradigms for AR interactions, this paper revisits Zigelbaum, Kumpf, Vazquez, and Ishiis 2008 project 'Slurp' [72] - a physical eyedropper to interact with digital content from IoT devices. We revive this historical work in a new modality of AR through a five step process: re-presecencing, design experimentation, scenario making, expansion through generative engagements with designers, and reflection. For the designers we engaged, looking back and designing with a restored prototype helped increased understanding of interactive strategies, intentions and rationales of original work. By revisiting Slurp, we also found many new potentials of its metaphorical interactions that could be applied in the context of emerging spatial computing platforms (e.g., smart home devices). In doing so, we discuss the value of mining past works in new domains and demonstrate a new way of thinking about designing interactions in emerging platforms.
