People using the internet have difficulty accessing and using Web content because the content cannot be changed to the specific needs of the individual user. This problem is especially troubling for people with disabilities like low vision and imprecise pointer movement.
Design of Web content is often limited to a one-size-fits-all approach to interaction and presentation that does not accommodate people with disabilities and personalized needs. This approach can render Web content unusable for such users: text is too small to read for people with low vision, color choice makes it difficult for people with color blindness to adequately distinguish, non-semantic content structure is frustrating for people using screen readers, small click areas and not enough spacing between them is a problem for people with imprecise pointer movement, and so on.
Any person who has need of altering the content display and/or interaction in order to read, navigate, and use the content.
The impact of which is
Minimally, a painful experience, and possibly an altogether failure to access or use the content.
A successful solution would
Provide a means by which each individual user could specify preference of the rendering and/or interaction with content, and the content would be transformed to meet those preferences.
