Designing for different kinds of users

Recently there has been a drive in interaction design to increase awareness about 'universal usability'. By this, it is meant designing for everyone, including those who are physically or psychologically challenged and people of different ages (children through to senior citizens), and those from different cultures. A website on universal usability has been developed with links to information about the diverse needs of different users.

Disabilities
The Trace Research & Development Center is a pioneer in the field of technology and disability. It provides online papers on how to design to support people with disabilities.

Designing for children
There is considerable interest in designing products with and for children, to support more effective play and learning. A portal site that has many pointers to relevant work can be found at Gary Perlman's HCIBIB site. Also see Allison Druin's site.
