An Embodied Conversational Agent in an eHealth Self-management Intervention for Chronic Obstructive Pulmonary Disease and Chronic Heart Failure: Exploratory Study in a Real-life Setting

An Embodied Conversational Agent in an eHealth Self-management Intervention for Chronic Obstructive Pulmonary Disease and Chronic Heart Failure: Exploratory Study in a Real-life Setting

But, ter Stal et al [32] showed that an agent’s design affects the user’s perception after short-term interaction, while Zhou et al [19] showed that this also applies to long-term interaction. How do you design an agent for self-management that creates positive impressions that persist? Our results suggest that an agent for self-management should be friendly, reliable, and involved and should have expertise, because patients rated these characteristics as important.

Embodied Conversational Agent Appearance for Health Assessment of Older Adults: Explorative Study

Embodied Conversational Agent Appearance for Health Assessment of Older Adults: Explorative Study

In one study, ter Stal et al [16] identified people’s first impressions of agents varying in age, gender, and role using a zero acquaintance approach: there was no interaction involved, and participants rated static agent images at first glance. The study shows that characteristics of older and male agents were perceived differently than characteristics of young and female agents, respectively. In addition, older adults seem to prefer a young female over an older male agent.
