Quantifying design exclusion (2002)
Presentation / Conference Contribution
Clarkson, P., & Keates, S. (2002). Quantifying design exclusion. In S. Keates, P. Langdon, P. J. Clarkson, & P. Robinson (Eds.), Universal access and assistive technology: Proceedings of the Cambridge workshop on UA and AT ’02 (22-32). https://doi.org/1

Products make demands of their users which effect their utility and usability. As a result, those users who do not have the capability to use the product are denied access to it. For example, a kettle that is so heavy that a weaker user cannot lift i... Read More about Quantifying design exclusion.

The older adult population in most developed countries is growing slowly, but continuously (Laslett, 1996). Several functional changes occur with age which may result in a decrease of perceptual, cognitive and motor skills (Smith et al., 2000). In sp...
