Images, videos, and virtual reality have been widely used in the literature to portray complex attributes to survey respondents. It is reasonable to expect immersive videos will be increasingly used in the future due to their decreasing costs and potentially more accurate representation of reality. Nevertheless, the literature has not sufficiently tested their ecological validity, which can be defined as the extent to which the results they produce in a laboratory setting, such as in choice experiments, are close enough to the results that would have been obtained in a real-life setting. The following work presents a comparison of two representation formats, images and immersive videos, to verify if they can elicit the same perceptual responses of pedestrians as real environments. To do this, a survey was carried out using these two formats as well as on-site interviews. Using a MIMIC approach, and after controlling for all relevant sociodemographic variables, results show that perceptions elicited through immersive videos were not different from those elicited in reality in one qualitative variable (perception of safety and security) out of three relevant ones identified. Furthermore, results also show immersive videos can induce a smaller distortion than photographs.

图像，视频和虚拟现实已在文献中广泛用于描述复杂的属性以调查受访者。可以预期，由于沉浸式视频的成本不断下降，并且可能会更精确地表示现实，因此在将来会越来越多地使用沉浸式视频。然而，文献尚未充分测试其生态有效性，这可以定义为它们在实验室环境（例如选择实验）中产生的结果与实际获得的结果足够接近的程度。生活设置。以下工作比较了两种表示形式，即图像和沉浸式视频，以验证它们是否能够引起行人与真实环境相同的感知响应。去做这个，使用这两种格式以及现场访谈进行了调查。使用MIMIC方法，并控制了所有相关的社会人口统计学变量之后，结果表明，通过沉浸式视频获得的感知与在确定的三个相关的定性变量（对安全性和安全性的感知）中对现实的感知并无不同。此外，结果还显示，沉浸式视频的失真比照片小。
