Seniors strongly prefer those websites that are easiest for them to use. The
correlation between the success score for our test tasks and users’ subsequent
subjective rating of the sites was very strong: r = 0.78, which is much higher than
we have found in most other studies, though not as high as the 0.95 we found in our
equivalent study of users with disabilities.
Usability for seniors is important, and not just so that they can perform a task aimed
at a one-time purchase. By focusing on improving usability for seniors, you can
increase their satisfaction and the odds of forming a long-term relationship. |
