A new system to measure color conspicuity: to know what color is vivid to people with low visual capacity

Since about 90% of the vision impaired in Japan are said to have low visual capacity (hereafter referred to as "LVs"), TWSIs visual recognizability has great significance. For color conspicuity, sufficient data on LVs is not yet collected, while the data on people with no vision impairment are ready. In order to study proper TWSIs colors, based on scientific-evidence and independent from conventional wisdom, we created a system to measure the conspicuity focusing exclusively on colors. In conclusion the system's usability to measure color conspicuity for LVs was verified.
