Design implications of a conversational agent in an implicitly-persuasive application

Persuasion can be used to encourage an individual to change his/her behaviors. However, persuading people in one of multiple behavior stages, such as a degree of achievement of target behavior, requires consideration suitable for each stage. We have proposed a persuasive application that implicitly encourages users to walk continuously in implicit manner. The persuasion is designed to be adapted to the users' estimated current behavior stage. Additionally, this application aims to enable users to walk actively while they play a location-based game and converse with an agent. In this paper, we discuss the design implications of a persuasive conversational agent in an implicitly persuasive application. We specify three aspects: adaptive persuasion, ubiquity and game mechanics.
