AN EXPERIMENT USING THE GRAPHIC VARIABLE COLOR AND THE SEE COLOR CODE ON ISARITHMIC MAPS ACCESSIBLE TO BLIND AND NORMALLY SIGHTED PEOPLE

Abstract: The See Color is a color coding system based on Braille writing to communicate colors to people with visual impairments. This study assessed the perception of the theme Temperature by blind people, by using the See Color code on two isarithmic tactile maps and the perception of subjects with normal color vision. An average temperature map of Australia had 10 classes, but these intervals were regrouped into four classes on Corel Draw software. The new map was duplicated in the digital project in A4 size, both included the See Color code in two color schemes obtained from the Color Brewer website. Subsequently, they were laser-printed on swell paper to produce the tactile relief. The chromatic perception was observed, as well as the thermal sensations that the colors could represent for blind participants (06), normally sighted participants in basic education (23), and normally sighted participants in higher education (20). In this research, the See Color code showed the potential to provide spatial knowledge as a graphic language through colors in color maps for adventitiously blind and for normally sighted participants based on their perception of colors and tactile color codes.

摘要：See Color编码系统（See Color）是一种基于盲文（Braille）的色彩编码方案，用于向视障群体传递色彩信息。本研究以两张等值线触觉地图为载体应用See Color编码，分别评估了盲人群体对温度主题的色彩感知效果，以及色觉正常受试者的同类感知表现。原澳大利亚平均气温地图包含10个温度分级，本研究通过CorelDRAW软件将其区间重新合并为4个分级。本数字项目制作了两份A4尺寸的新版地图，二者均采用从Color Brewer配色工具（Color Brewer）网站获取的两种配色方案，并嵌入了See Color编码。随后将两份地图通过激光打印于膨润纸（swell paper）上，以生成触觉浮雕效果。本次研究观测了色彩感知效果，以及色彩所能传递的温度感知，测试对象包括6名盲人群体受试者、23名基础教育阶段色觉正常受试者以及20名高等教育阶段色觉正常受试者。研究结果表明，基于受试者对色彩及触觉色彩编码的感知，See Color编码作为一种图形语言，可通过彩色地图中的色彩为后天失明者与色觉正常受试者提供空间认知支持，具备良好的应用潜力。
