Design of an AR Application to Support Students with CVD in Learning Chemistry

Color Vision Deficiency (CVD) is a common visual impairment. Research shows that CVD affects studying and life by facing difficulties in color distinction. However, it often relies on people having CVD to self-adjust or find alternative tools when resolving the problem or providing general color distinguishing support without considering the need for reading and learning in a specific subject. Therefore, this research dives into using augmented reality(AR), particularly its synchronous integration feature, to develop color vision support in science learning and design a system to support CVD students in high school chemistry reading. This research first reviewed existing technological approaches to support color vision, and the national curriculum of chemistry in secondary education. An exemplary lesson plan with the selected topic of the universal indicator was developed accordingly to test the AR color vision support with a texture-based approach. 8 high school students joined the user testing to assess the interface and flow of the prototype.
