Approximately, 1 of 12 persons in the world has colour vision deficiency (CVD), named colour blindness. While the amount of graphic information in digital contents is continuing to increase dramatically, assistive tools for colour vision deficiencies remain scarce.
We developed a method to generate customised International Colour Consortium (ICC) colour profiles for patients suffering from CVD, which could adjust graphic contents according to individual needs. Compensation rules for the pale or dark range of red and green colours were established, and an ICC profile was generated using this set of rules.
The passing rate for Ishihara test was 99.5% when the generated profile was applied to 10 Ishihara plates and tested on individuals suffering from red deficiency, and green deficiency (5, and 15 participants, respectively). The time used to generate the compensation profile was 12.9 min on average, including the time taken to explain the test to the participants.
Reliable results were achieved with a relatively low effort in comparison with methods currently utilised in professional clinics, and does not need expensive instruments.
世界上约每12人中就有1人患有色觉缺陷(CVD),即色盲。尽管数字内容中的图形信息数量在持续急剧增加,但针对色觉缺陷的辅助工具仍然稀缺。
我们开发了一种方法,为患有CVD的患者生成定制的国际色彩联盟(ICC)色彩配置文件,该文件可根据个人需求调整图形内容。建立了红色和绿色淡色或深色范围的补偿规则,并使用这组规则生成了ICC配置文件。
将生成的配置文件应用于10张石原氏色盲测试图,并分别对15名红色缺陷患者和5名绿色缺陷患者进行测试时,石原氏色盲测试的通过率为99.5%。生成补偿配置文件的平均用时为12.9分钟,包括向参与者解释测试所需的时间。
与专业诊所目前使用的方法相比,该方法以相对较低的工作量取得了可靠的结果,且不需要昂贵的仪器。
