Hi,

A recent press announcement from the Norman Nielsen group about its report
'Beyond ALT Text: Making the Web Easy to Use for Users with Disabilities'
(http://www.nngroup.com/reports/accessibility) included some rather
disconcerting statistics from the research:

      * Task completion rate:
          Screen reader users were able to complete the tasks given to them 12.5% of the time;
          screen magnifier users 21.4% of the time;
          control group 78% of the time.

      * Time on a task (min:sec):
          Screen reader users spent 16:34 on task;
          screen magnifier users spent 15:26 on task;
          control group 7:14 on task.

      * Errors (average across all tasks):
          Screen reader users 2.0;
          screen magnifier users 4.5;
          control group .06.

      * Subjective rating (1-7 scale with 7 indicating the most positive):
          Screen reader users 2.5;
          screen magnifier users 2.9 on task;
          control group 4.6.
