We discuss issues in designing virtual humans for applications which require long-term voluntary use, and the problem of maintaining engagement with users over time. Concepts and theories related to engagement from a variety of disciplines are reviewed. We describe a platform for conducting studies into long-term interactions between humans and virtual agents, and present the results of two longitudinal randomized controlled experiments in which the effect of manipulations of agent behavior on user engagement was assessed.
我们讨论了为需要长期自愿使用的应用设计虚拟人的相关问题,以及随着时间推移与用户保持互动的问题。我们回顾了来自多个学科的与互动相关的概念和理论。我们描述了一个用于研究人类与虚拟代理之间长期互动的平台,并展示了两项纵向随机对照实验的结果,在这些实验中评估了代理行为的操纵对用户互动的影响。
