Now we have "Playstation Thumb". 13-year old Safura Abdool Karim of South Africa is the youngest person to be published in that country's main medical journal. Her research on "Playstation Thumb" will be included in the next issue. Now in recent year there has been lots published on repetitive strain injuries. However most of that information has delt with adults. Safura's work addresses children. This clearly points out that there is no application and no population that is imune from the need for good human factors design. Are your products human factors friendly? What are you doing about it?
