SkyWhal3/ARIA_CVI_AAC_Photoset

CVI AAC照片集是一个免费的、照片级真实的图像库，专为患有皮质视觉障碍(CVI)并使用增强和替代沟通(AAC)板的儿童设计。皮质视觉障碍是发达国家儿童视觉障碍的主要原因。现有的AAC词汇库（如ARASAAC、Mulberry、OpenSymbols等）多为象形图风格（白色或彩色背景上的线条画），而CVI儿童的皮质视觉处理难以解析这些图像。CVI用户在以下情况下看得最清楚：纯黑色背景（#000000）以消除视觉杂乱；单一、明亮、高饱和度的真实世界物体；紧密的特写构图以填满AAC图块的视野；照片级真实感而非抽象图像以支持物体识别和泛化到物理世界。该数据集包含1947+张图像，分为28个类别，所有图像都采用一致的视觉风格渲染。A free, photo-realistic image library for children with Cortical Visual Impairment (CVI) who use Augmentative and Alternative Communication (AAC) boards. Cortical Visual Impairment is the leading cause of childhood visual impairment in the developed world. Existing AAC vocabulary libraries (ARASAAC, Mulberry, OpenSymbols, SymbolStix, Boardmaker, etc.) are pictogram-style — line drawings on white or colored backgrounds — which the childs cortical visual processing struggles to parse. CVI users see best when shown: Pure black backgrounds (#000000) — eliminates visual clutter; Single, brightly-colored, high-saturation real-world objects — saturated color is the strongest visual hook; Tight close-up framing — fills the visual field of an AAC tile; Photo-realistic, not abstract — supports object recognition and generalization to the physical world. This dataset is 1947+ images across 28 categories, all rendered with one locked prompt prefix so visual style is consistent across the entire library.
