The Impact

This article presents the design and evaluation of a gamified mobile tour guide prototype for route-finding in historical attractions. The mobile tour guide prototype uses photographs of landmarks carefully chosen to guide visitors on routes of cultural interest in the castle. It also features a fully multimodal interface using an Embodied Conversational Agent (ECA). The authors compared the impact of the multimodal interface to a non-multimodal control (narrated text) for the same navigational tasks. Participants experienced routes of variable difficulty (simple vs complex) in the lab under simulated mobile conditions. The experimental results substantiated aspects of the ECA-based interface related to visitors' subjective experiences, but not objective task performance. Finally, the authors discuss future work which will focus on running the second round of evaluations in the field with an improved version of the prototype, demonstrating features such as user planned routes and route re-calculation.

Transition To Retirement

Background: Retirement is recognized as a factor influencing the ageing process. Today, virtual health coaching systems can play a pivotal role in supporting older adults’ active and healthy ageing. This study wants to answer two research questions: (1) What are the user requirements of a virtual coach (VC) based on an Embodied Conversational Agent (ECA) for motivating older adults in transition to retirement to adopt a healthy lifestyle? (2) How could a VC address the active and healthy ageing dimensions, even during COVID-19 times? Methods: Two-wave focus-groups with 60 end-users aged 55 and over and 27 follow-up telephone interviews were carried out in Austria, Italy and the Netherlands in 2019–2020. Qualitative data were analysed by way of framework analysis. Results: End-users suggest the VC should motivate older workers and retirees to practice physical activity, maintain social contacts and emotional well-being. The ECA should be reactive, customizable, expressive, sympathetic, not directive nor patronizing, with a pleasant and motivating language. The COVID-19 outbreak increased the users’ need for functions boosting community relationships and promoting emotional well-being. Conclusions: the VC can address the active and healthy ageing paradigm by increasing the chances of doing low-cost healthy activities at any time and in any place.

The design and development of a motivational embodied conversational agent for brain injury rehabilitation is discussed. Results for initial prototype design and implementation, and alpha and beta testing phases are presented. Key aspects identified during development included supporting user engagement via personalization and choice-making; integrating behaviour change principles into dialogues; addressing clinical needs of cognitive fatigue and memory loss within conversation structure; and optimizing feasibility of use in a real-life clinical setting.

Metacognitive training reflects knowledge, consideration and control over decision-making and task performance evident in any social and learning context. Interest in understanding the best account of effective (win-win) negotiation emerges in different social and cultural interactions worldwide. The research presented in this paper explores an extended study of metacognitive training system during negotiation using an embodied conversational agent. It elaborates on the findings from the usability evaluation employing 40 adult learners pre- and postinteraction with the system, reporting on the usability and metacognitive, individual- and community-level related attributes. Empirical evidence indicates (a) higher levels of self-efficacy, individual readiness to change and civic action after user-system experience, (b) significant and positive direct associations between self-efficacy, self-regulation, interpersonal and problem-solving skills, individual readiness to change, mastery goal orientation and civic action pre- and postinteraction and (c) gender differences in the perceptions of system usability performance according to country of origin. Theoretical and practical implications in tandem with future research avenues are discussed in light of embodied conversational agent metacognitive training in negotiation.
