摘要
视觉系统通过改变对环境的敏感度来适应颜色的变化。自然观看下的色彩适应研究使观察者暴露于使用滤镜或透镜的简单变换(Neitz等人,2002年,Engel等人,2016年)。我们的视觉系统是否能像适应复杂的视觉空间操作那样适应复杂的色彩变换,这是一个悬而未决的问题(Richter et al., 2002)。改变现实(AR)设备让我们能够解决这个问题。Grush等人(2015)从两个观察者那里提供了定性证据,表明他们对颜色的感知体验在AR暴露于色彩旋转的世界后发生了改变。我们将观察者暴露在AR头显(Meta Quest 3)中的实时传递馈送中,在HSL空间中应用120度的色调旋转(例如,蓝色的天空变成品红)。观察者(N = 8)沉浸在积极或消极的色调旋转中,在此期间,他们通过日常活动与非自然色彩的世界互动,包括在大自然中散步,绘画,选择和吃食物等。我们测量了观察者在适应之前对独特黄色和独特蓝色的感知,并在他们暴露于色彩旋转的世界中每小时测量一次,最长可达4小时。我们的研究结果揭示了视觉适应性的局限性,阐明了适应是否延伸到非自然的颜色转换,并试图揭示长期适应的时间特征。
Poster Session: Measuring the limits of long-term adaptation to hue-rotated altered reality.
The visual system adapts to chromatic changes by altering its sensitivity to the environment. Research on chromatic adaptation under natural viewing has exposed observers to simple transformations using filters or lenses (Neitz et al.,2002, Engel et al., 2016). It is an open question whether our visual system adapts to complex chromatic transformations as it does for complex visuospatial manipulations (Richter et al., 2002). Altered reality (AR) devices allow us to address this question. Grush et al., (2015) provided qualitative evidence from two observers that their perceptual experience of colour was altered after AR exposure to a hue-rotated world. We exposed observers to a real-time pass-through feed in an AR headset (Meta Quest 3), applying a hue rotation of 120 degrees in HSL space (e.g., blue sky turns magenta). Observers (N = 8) were immersed in either a positive or negative hue rotation during which they interacted with the unnaturally coloured world through everyday activities including walking in nature, painting, selecting and eating food, etc. We measured the observers' perception of unique yellow and unique blue prior to adaptation and each hour during their exposure to the hue-rotated world, for up to four hours. Our results expose the limits of visual adaptability, elucidating whether adaptation extends to unnatural chromatic transformations and attempt to shed light on the temporal characteristics of long-term adaptation.
