abstract = {Proactivity is a sought-after feature in Voice Assistants (VA) and considered
the next sensible step in growing from merely reactive to more conversational
interfaces. Creating proactive use cases thereby poses a challenging design task with
a multitude of potential pitfalls. Proactive interactions possibly interrupt users who are
already conducting important, demanding, and potentially even security-relevant primary
tasks, e.g., driving a car. So far, research has identified precise timing and careful
consideration of primary task engagement as key to successful proactive interactions.
While there is substantial literature on proactive VAs in terms of when to interrupt
users, how to interrupt them has received less attention. Previous research has shown
that VA users are susceptible to differing formulations of VA system outputs
(prompts) though and that they prefer some formulations over others. Syntactical,
grammatical, and lexical nuances play a role in how a VA is being perceived. To close
the gap of to date insufficient linguistic-driven design guidelines for proactive VAs, a
crowdsourcing study was conducted to examine users’ formulation preferences for
proactive prompts in an automotive setting. Our findings show concrete syntactical
best practices for formulating proactive in-car prompts, thereby allowing for the compilation
of hands-on design guidelines.},
