本研究分别调查了第一人称视角（1PP）和第三人称视角（3PP）对《第二人生》三维虚拟环境的情感评估和用户参与度的影响。参与者在有限的时间内使用 1PP 或 3PP 探索环境，同时搜索五个目标。没有发现观察视角对三维虚拟环境对唤醒和效价维度的评估有显着的总体影响。然而，3PP 可以对化身和事件产生更多感知控制，这是参与的要求。对搜索任务性能的分析表明，使用 3PP 的参与者找到了更多的对象，但也需要更多的时间来找到它们。目前的结果表明，3PP 传达了对环境的更独特的印象，从而增加了参与度，并可能引发不同的观看策略。因此，3PP 似乎更适合模拟和培训应用，在这些应用中，正确评估环境的情感属性至关重要。
This study investigates the influence of a first-person perspective (1PP) and a third-person perspective (3PP), respectively, on the affective appraisal and on the user engagement of a three-dimensional virtual environment in SECOND LIFE. Participants explored the environment while searching for five targets during a limited time span, using either a 1PP or a 3PP. No significant overall effect was found for viewing perspective on the appraisal of the three-dimensional virtual environment on the dimensions of arousal and valence. However, a 3PP yields more perceived control over the avatar and the events, which is a requirement for engagement. Analysis of the performance on the search task shows that participants using a 3PP find more objects but also need more time to find them. The present results suggest that a 3PP conveys a more distinct impression of the environment, thereby increasing engagement, and probably induces a different viewing strategy. Hence, a 3PP appears preferable for simulation and training applications in which the correct assessment of the affective properties of an environment is essential.
