Abstract The use of virtual reality (VR) in sensory science studies can offer new possibilities for experimental design. For instance, VR allows for the modification of visual product properties without changing the product composition. In a set of two augmented virtuality studies, we investigated whether the results we obtained in real-life (RL) settings were comparable to the results we obtained in a VR environment. In Study 1, we transferred an existing sensory science experiment to a VR setting. We invited 100 participants to taste two juices and a piece of cake. In the VR environment, participants saw the product either in its original colour or in a modified, product-atypical colour. After the product tasting, we asked them to identify the most dominant flavour. Participants had more difficulties identifying the flavour when the product was shown in a modified colour than when it was shown in its original colour. In Study 2, we added an RL control condition to facilitate a direct comparison between the two conditions and to verify our findings from Study 1. A chi-square test for association revealed no significant differences between the RL and VR conditions. We conclude that sensory studies can be successfully transferred to VR and obtain a generally similar pattern of results.

真彩：虚拟现实在感官科学实验中对颜色对风味识别的影响的优势和挑战

摘要 在感官科学研究中使用虚拟现实 (VR) 可以为实验设计提供新的可能性。例如，VR 允许在不改变产品组成的情况下修改视觉产品属性。在一组两个增强虚拟性研究中，我们调查了我们在现实生活 (RL) 设置中获得的结果是否与我们在 VR 环境中获得的结果相当。在研究 1 中，我们将现有的感官科学实验转移到 VR 环境中。我们邀请了 100 名参与者品尝两种果汁和一块蛋糕。在 VR 环境中，参与者看到产品的原始颜色或修改后的非典型颜色。产品品尝后，我们要求他们确定最主要的味道。与以原始颜色显示产品相比，当产品以修改后的颜色显示时，参与者更难识别其风味。在研究 2 中，我们添加了 RL 控制条件，以促进两种条件之间的直接比较，并验证我们在研究 1 中的发现。关联的卡方检验显示 RL 和 VR 条件之间没有显着差异。我们得出结论，感官研究可以成功转移到 VR 并获得大致相似的结果模式。
