Color is commonly used to represent categories and values in many computer applications, but differentiating these colors can be difficult in many situations (e.g., for users with color vision deficiency (CVD), or in bright light).Current solutions to this problem can adapt colors based on standard simulations of CVD, but these models cover only a fraction of the ways in which color perception can vary.Moore characterizes broadly used technologies as Main Street which is in harmony with the notions of universal usability serving the needs of every citizen.Students who have physical, cognitive, sensory, and learning disabilities might find learning mathematics particularly challenging.

Different from the general image search scheme that aims at returning more relevant results, AIS further takes into account the colorblind accessibilities of the returned results, i.e., the image qualities in the eyes of colorblind users.

Situation-specific models are a recent approach that accounts for all of the factors affecting a person’s CVD (including genetic, acquired, and environmental causes) by using calibration data to form the model.

This approach works well, but requires repeated calibration – and the best available calibration procedure takes more than 30 minutes.

Not only that, although your personal information will be safe!

Color is commonly used to represent categories and values in many computer applications, but differentiating these colors can be difficult in many situations (e.g., for users with color vision deficiency (CVD), or in bright light).The scheme includes two components: accessibility assessment and accessibility improvement.
