Tangible Tetris is a mixed-reality interactive game allowing play with a physical transformable tetromino in a virtual playfield. The extension from game world to the physical brings plenty of new characteristics, strategies and fun to the classic game, as well as more possibilities in interactive art.
A production experiment was conducted to investigate the role of perspective-taking in the prosodic marking of information structure. Participants played an interactive game in which they produced verbal instructions that directed an addressee to place objects in locations on the computer screen. We manipulated (i) the participants’ assumptions about the addressee’s familiarity with the objects and (ii) the addressee’s accuracy in identifying the objects. F0 measurements of the participants’ utterances were analyzed with Smoothing-spline ANOVA models. We find that speakers’ expectations about the addressee’s knowledge state influence the prosodic realization of both new and given information, and that speakers rapidly update their expectations based on the addressee’s behavior during the conversation.
