This study explored user needs for a digital companion to promote healthy behaviors. Findings show tailoring the companion's argumentative style significantly impacts user acceptance and effectiveness.
Area of Science:
- Human-Computer Interaction
- Behavioral Science
- Digital Health
Background:
- Digital companions offer potential for supporting behavior change.
- Understanding user-centric aspects is crucial for effective design.
- Previous research has not fully explored user perceptions of argumentative dialogue in digital health interventions.
Purpose of the Study:
- To empirically elicit requirements for an argumentation-based digital companion for behavior change.
- To investigate human-centric aspects, including user motivations, expectations, and perceptions of the companion's role and interaction behavior.
- To inform the design of personalized digital health tools.
Main Methods:
- Empirical requirement elicitation study involving non-expert users and health experts.
- Development and utilization of prototypes to gather user feedback.
- Qualitative and quantitative analysis of user interactions and perceptions.
Main Results:
- User acceptance and intervention effectiveness are significantly influenced by the digital companion's argumentative approach (challenging vs. supporting) and assertiveness.
- Personalization of the agent's roles and argumentation schemes is key for tailoring interactions.
- Users and experts perceive "soft" meta-level aspects of argumentative dialogue as important.
Conclusions:
- A framework for personalized digital companion design, incorporating tailored roles and argumentation schemes, is proposed.
- The study highlights the critical role of individualized interaction strategies in promoting healthy behaviors.
- Further research is needed into the nuanced perception of argumentative dialogue in digital health contexts.
