Analysis of expert medical diagnostic critiquing dialogues shows that explanation, argumentation and negotiation are strongly interlinked. After presenting analyses of a corpus of Wizard of Oz dialogues in this domain, we describe a design for a graphical integace that enables human-computer collaboration for the same task. Many of the dialogues' functionalities can be transferred to the interface, whilst avoiding natural language interpretation problems and providing a comparable degree of expressivity for the user.
The Acoustic Localization Positioning System is the outcome of several years of participatory development with musicians and artists having a stake in sonic arts, collaboratively aiming for nonobtrusive tracking and indoors positioning technology that facilitates spatial interaction and immersion. Based on previous work on application scenarios for spatial reproduction of moving sound sources and the conception of the kinaesthetic interface, a tracking system for spatially interactive sonic arts is presented here. It is an open-source implementation in the form of a stand-alone application and associated Max patches. The implementation uses off-the-shelf, ubiquitous technology. Based on the findings of tests and experiments conducted in extensive creative workshops, we show how the approach addresses several technical problems and overcomes some typical obstacles to immersion in spatially interactive applications in sonic arts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
