Abstract
In many circumstances, concepts, ideas and emotions are mainly conveyed by colors. Color vision disorders can heavily limit the user experience in accessing Information Society. Therefore, color vision impairments should be taken into account in order to make information and services accessible to a broader audience. The task is not easy for designers that generally are not affected by any color vision disorder. In any case, the design of accessible user interfaces should not lead to to boring color schemes. The selection of appealing and harmonic color combinations should be preserved. In past research we investigated a generative approach led by evolutionary computing in supporting interface designers to make colors accessible to impaired users. This approach has also been followed by other authors. The contribution of this paper is to provide an experimental validation to the claim that this approach is actually beneficial to designers and users.
Highlights
Colors can be one of the main barriers to the Information Society for color vision impaired users.1 Colors convey concepts, ideas and emotions, according to cultural and individual traits
Among them we considered the problem of adapting color schemes to users affected by vision disorders by means of standard genetic algorithms (SGA) (Troiano et al 2008b) and interactive genetic algorithms (IGA) (Birtolo et al 2009)
Color accessibility represents a relevant barrier for CVD users in gaining access to the Information Society
Summary
Colors can be one of the main barriers to the Information Society for color vision impaired users. Colors convey concepts, ideas and emotions, according to cultural and individual traits. Colors can be one of the main barriers to the Information Society for color vision impaired users.. Ideas and emotions, according to cultural and individual traits. If there exist colors entailing joy and relax, others produce excitement or melancholy. Not perceiving the colors properly can invalidate the purpose of communication. In 2004, the UK Disability Rights Commission (DRC) reported their formal investigation regarding accessibility of websites in the UK (Disability Rights Commission 2004). The 81 % of sample did not meet W3C basic guidelines for accessibility, most of website designers and owners are aware of the importance of making accessible the Web. According to this study, misperceived colors are the second main barrier to impaired users. In order to break down this barrier, there is a shared
