Planning Habit: Daily Planning Prompts with Alexa

摘要

The widespread adoption of intelligent voice assistants (IVAs), like Amazon's Alexa or Google's Assistant, presents new opportunities for designers of persuasive technologies to explore how to support people's behavior change goals and habits with voice technology. In this work, we explore how to use planning prompts， a technique from behavior science to make specific and effective plans, with IVAs. We design and conduct usability testing (N = 13) on a voice app called Planning Habit that encourages users to formulate daily plans out loud. We identify strategies that make it possible to successfully adapt planning prompts to voice format. We then conduct a week-long online deployment (N ― 40) of the voice app in the context of daily productivity. Overall, we find that traditional forms of planning prompts can be adapted to and enhanced by IVA technology.
