Inaccessible Technology

Technology must enable the following access to accommodate users with low
vision: Users must be capable of adjusting the visual interface to meet
their exact visual needs [issue 74]. When an implementation for the web
denies this level of flexibility to its users, it is inaccessible to some
large population of people with low vision. Depending on the aspects of the
visual interface that are impossible to change, the groups of people low
vision that will be left out will differ . When no implementation of a
technology can meet this need, then the entire technology is inaccessible.
We know that HTML/CSS/JavaScript can produce rich implementations that meet
this need. Thus, the set of accessible technology is not empty.


What do we do with technologies that cannot meet the visual flexibility
requirement? In the case of non-text content regarding blindness, we simply
require a text alternative. In the case where a technology cannot meet
visual flexibility do we just require an accessible technology alternative?
