严肃游戏中写实型与动画型具身对话智能体的比较：一项关于用户体验的实证研究
Comparing Photorealistic and Animated Embodied Conversational Agents in Serious Games: An Empirical Study on User Experience
AI总结：
本文通过36名参与者的被试内实验，比较严肃游戏中写实型与动画型具身对话智能体的用户体验，发现两者可用性均高且写实型更受偏好，为后续ECA真实感研究奠定基础。
摘要：
具身对话智能体（ECAs）是以具身角色形式呈现的对话用户界面范式。尽管ECAs提供了多种可操控特征，本文聚焦于一项旨在探索两种不同呈现真实感水平的研究。两个智能体版本分别为写实型和动画型。该研究旨在为严肃游戏环境中支持语音的ECAs提供见解和设计建议。本研究采用被试内、二乘二析因设计，共有36名性别均衡的参与者。结果显示，写实型和动画型版本都被认为具有很高的可用性，总体平均得分分别为5.76和5.71。然而，69.4%的参与者表示他们更喜欢写实型版本，25%表示更喜欢动画型版本，5.6%没有明确偏好。写实型智能体被认为更真实、更接近人类，而动画角色使任务感觉更像游戏。尽管智能体的真实感对可用性没有显著影响，但它积极影响了参与者对智能体的感知。本研究旨在为未来关于ECA真实感在不同情境下严肃游戏中影响的研究奠定基础。
英文摘要：
Embodied conversational agents (ECAs) are paradigms of conversational user interfaces in the form of embodied characters. While ECAs offer various manipulable features, this paper focuses on a study conducted to explore two distinct levels of presentation realism. The two agent versions are photorealistic and animated. The study aims to provide insights and design suggestions for speech-enabled ECAs within serious game environments. A within-subjects, two-by-two factorial design was employed for this research with a cohort of 36 participants balanced for gender. The results showed that both the photorealistic and the animated versions were perceived as highly usable, with overall mean scores of 5.76 and 5.71, respectively. However, 69.4 per cent of the participants stated they preferred the photorealistic version, 25 per cent stated they preferred the animated version and 5.6 per cent had no stated preference. The photorealistic agents were perceived as more realistic and human-like, while the animated characters made the task feel more like a game. Even though the agents' realism had no significant effect on usability, it positively influenced participants' perceptions of the agent. This research aims to lay the groundwork for future studies on ECA realism's impact in serious games across diverse contexts.
