Scientific knowledge is still limited about the effect of commercial virtual reality content, such as experiences developed for advertising purposes, on individual emotional experience. In addition, even though correlations between emotional responses and perceived sense of presence in virtual reality have often been reported, the relationship remains unclear. Some studies have suggested an important effect of ease of interaction on both emotions and the sense of presence, but only a few studies have scientifically explored this topic. Within this context, this study aimed to: (a) test the effect of inducing positive emotions of a commercial virtual experience developed for the promotion of an urban renewal project, (b) investigate the relationship between positive emotions and the perceived sense of presence, and (c) explore the association between the ease of interaction of the virtual experience with positive emotions and the sense of presence reported by the users. Sixty-one participants were recruited from visitors to the 2017 Milan Design Week “Fuorisalone” event. A survey was administered before and after the experience to collect information about users' demographics, positive emotions, sense of presence, and the ease of interaction with the virtual content. Results give evidence that: (a) the commercial virtual reality experience was able to induce positive emotions; (b) the positive emotions reported by users were associated with the sense of presence experienced in the virtual environment, with a directional effect from emotion to sense of presence; and (c) the easier the interaction, the more the sense of presence and positive emotions were reported by users.

虚拟现实系统中的积极情绪、存在感和易于交互之间的关系是什么？商业虚拟体验的现场评估

关于商业虚拟现实内容（例如为广告目的而开发的体验）对个人情感体验的影响，科学知识仍然有限。此外，即使经常报道虚拟现实中情绪反应和感知存在感之间的相关性，但这种关系仍不清楚。一些研究表明，易于交互对情绪和存在感都有重要影响，但只有少数研究对这一主题进行了科学探索。在此背景下，本研究旨在：(a) 测试为促进城市更新项目而开发的商业虚拟体验诱发积极情绪的效果，(b) 调查积极情绪与感知存在感之间的关系，(c) 探索虚拟体验与积极情绪互动的难易程度与用户报告的存在感之间的关联。从 2017 年米兰设计周“Fuorisalone”活动的参观者中招募了 61 名参与者。在体验前后进行了一项调查，以收集有关用户人口统计、积极情绪、存在感以及与虚拟内容交互的难易程度的信息。结果证明：（a）商业虚拟现实体验能够诱发积极情绪；(b) 用户报告的积极情绪与在虚拟环境中体验到的存在感相关，具有从情绪到存在感的定向效应；(c) 互动越容易，
