摘要：
我们提出了一种辅助技术，帮助色觉缺陷（CVD）个体识别/命名颜色。双色视觉者的颜色感知是正常三色视觉者三维（3D）颜色感知的降维二维（2D）子集，当对双色视觉者来说看起来相同的视觉刺激被称为不同的颜色名称时，就会导致混淆。使用我们提出的系统，CVD个体可以通过计算颜色空间变换，交互式地对原本混淆的颜色引发不同的感知变化。通过将他们原本对颜色的2D感知与这些区分性变化相结合，重建了一个三维颜色空间，双色视觉者可以在其中学会解决颜色名称混淆并准确识别颜色。我们的系统在智能手机上实现为增强现实（AR）界面，用户可以通过滑动交互式地控制旋转，并在相机视图或显示的图像中观察引发的颜色偏移。通过心理物理学实验和纵向用户研究，我们证明了这种旋转颜色偏移具有区分能力（最初混淆的颜色在旋转下变得可区分），并表现出双色视觉者通过适度训练即可学习的结构化感知偏移。该AR App还在两个真实场景（用乐高积木拼搭和解读艺术作品）中进行了评估；所有用户都报告了使用该App识别物体颜色的积极体验，否则他们无法识别这些颜色。
英文摘要：
We propose an assistive technology that helps individuals with Color Vision Deficiencies (CVD) to recognize/name colors. A dichromat's color perception is a reduced two-dimensional (2D) subset of a normal trichromat's three dimensional color (3D) perception, leading to confusion when visual stimuli that appear identical to the dichromat are referred to by different color names. Using our proposed system, CVD individuals can interactively induce distinct perceptual changes to originally confusing colors via a computational color space transformation. By combining their original 2D precepts for colors with the discriminative changes, a three dimensional color space is reconstructed, where the dichromat can learn to resolve color name confusions and accurately recognize colors. Our system is implemented as an Augmented Reality (AR) interface on smartphones, where users interactively control the rotation through swipe gestures and observe the induced color shifts in the camera view or in a displayed image. Through psychophysical experiments and a longitudinal user study, we demonstrate that such rotational color shifts have discriminative power (initially confusing colors become distinct under rotation) and exhibit structured perceptual shifts dichromats can learn with modest training. The AR App is also evaluated in two real-world scenarios (building with lego blocks and interpreting artistic works); users all report positive experience in using the App to recognize object colors that they otherwise could not.
