Universal Usability needs to be commercially practical so these products can be used by real people in real situations and not limited to abstract research. Design can be generalized to those who are not disabled and who may need more usable products in a variety of contexts. Governments and commercial organizations are becoming more interested in accessibility for their clients and employees.
Disability is complex.
Gregg Vandereiden mentioned there were approximately three hundred strategies for making products more accessible. Designers must prioritize and determine what they need to focus on. Therefore, they focus on what is easy and produce products that may not be usable by anyone. This paper attempts to come up with a method of prioritizing between possible changes to a product's interface. The paper discusses a multidimensional prioritization approach to solving these design issues.
