Interactions between humanhuman multi-threaded dialogues and driving
In-car devices with speech user interfaces are proliferating. How can we build these interfaces such that they allow humancomputer interactions with multiple devices to overlap in time, but without interfering with the driving task? We suggest that interface design can be inspired by the way people deal with this problem in humanhuman dialogues and propose discovering human dialogue behaviors of interest through experiments. In this paper, we discuss how to design an appropriate humanhuman dialogue scenario for such experiments. We also report on one humanhuman experiment, in terms of the dialogue behaviors found, and impact on the verbal tasks and on driving. We also offer design considerations based on the results of the study.
