Social signal processing and virtual social interaction technologies have allowed the creation of social skills training applications, and initial studies have shown that such solutions can lead to positive training outcomes and could complement traditional teaching methods by providing cheap, accessible, safe tools for training social skills. However, these studies evaluated social skills training systems as a whole and it is unclear to what extent which components contributed to positive outcomes. In this paper, we describe an experimental study where we compared the relative efficacy of real-time interactive feedback and after-action feedback in the context of a public speaking training application. We observed that both components provide benefits to the overall training: the real-time interactive feedback made the experience more immersive and improved participants’ motivation in using the system, while the after-action feedback led to positive training outcomes when it contained personalized feedback elements. Taken in combination, these results confirm that both social signal processing technologies and virtual social interactions are both contributing to social skills training systems’ efficiency. Additionally, we observed that several individual factors, here the subjects’ initial level of public speaking anxiety, personality and tendency to immersion significantly influenced the training experience. This finding suggests that social skills training systems could benefit from being tailored to participants’ particular individual circumstances.

社交信号处理和虚拟社交互动技术已允许创建社交技能培训应用程序，并且初步研究表明，此类解决方案可以带来积极的培训成果，并可以通过提供廉价，可访问，安全的社交技能培训工具来补充传统的教学方法。但是，这些研究对社交技能培训系统进行了整体评估，尚不清楚哪些成分在多大程度上有助于取得积极成果。在本文中，我们描述了一项实验研究，在公共演讲培训应用程序的背景下，我们比较了实时交互式反馈和事后反馈的相对功效。我们观察到，这两个部分都为整体培训带来了好处：实时互动反馈使体验更加身临其境，并提高了参与者使用该系统的动力，而事后反馈在包含个性化反馈元素时带来了积极的培训成果。综合考虑，这些结果证实社交信号处理技术和虚拟社交互动都对社交技能培训系统的效率做出了贡献。此外，我们观察到一些个人因素，在这里，受试者的公开演讲焦虑，个性和沉浸倾向的初始水平显着影响了训练体验。这一发现表明，社交技能培训系统可以从针对参与者的特定个人情况量身定制中受益。而事后反馈如果包含个性化的反馈元素，则可以带来积极的培训成果。综合考虑，这些结果证实社交信号处理技术和虚拟社交互动都对社交技能培训系统的效率做出了贡献。此外，我们观察到一些个人因素，在这里，受试者的公开演讲焦虑，个性和沉浸倾向的初始水平显着影响了训练体验。这一发现表明，社交技能培训系统可以从针对参与者的特定个人情况量身定制中受益。而事后反馈如果包含个性化的反馈元素，则可以带来积极的培训成果。综合考虑，这些结果证实社交信号处理技术和虚拟社交互动都对社交技能培训系统的效率做出了贡献。此外，我们观察到一些个人因素，在这里，受试者的公开演讲焦虑，个性和沉浸倾向的初始水平显着影响了训练体验。这一发现表明，社交技能培训系统可以从针对参与者的特定个人情况量身定制中受益。这些结果证实，社交信号处理技术和虚拟社交互动都在促进社交技能培训系统的效率。此外，我们观察到一些个人因素，在这里，受试者的公开演讲焦虑，个性和沉浸倾向的初始水平显着影响了训练体验。这一发现表明，社交技能培训系统可以从针对参与者的特定个人情况量身定制中受益。这些结果证实，社交信号处理技术和虚拟社交互动都在促进社交技能培训系统的效率。此外，我们观察到了几个个体因素，在这里，受试者的公开演讲焦虑，个性和沉浸倾向的初始水平显着影响了训练体验。这一发现表明，社交技能培训系统可以从针对参与者的特定个人情况量身定制中受益。
