Usability Considerations for Older People (Cont)
5. Link identification - Test results showed that people from the older age group were more likely to mistakenly click on parts of the pages that weren’t links. Everyone in the older age group also stated the importance of having visited links change in colour so as to help them remember which ones they have clicked before.
6. Attitude towards downloading - Those in the older aged group had a more negative attitude towards downloading expressing worry over viruses and any other harmful thing their computer might get. In comparison, those in the younger age group didn’t seem to mind downloading at all.
7. Search Usage - More people in the older age group used the search function to help them navigate. Despite not using the search function much, those in the younger age group was in agreement with the older age group regarding the need for a search function that will make all of the website’s content searchable.
8. Speed in reading and task completion - Not surprisingly, those in the older age group needed more than twice as much time to finish tasks. This is probably due to fact that they not only read the content more slowly but also more thoroughly.
9. Design preference - Those in the older age group showed a preference for big fonts. They had a hard time reading text displayed in anything smaller than a 12-point type. Those in the older age group also preferred a screen resolution of 800×600 over 1024×768. Aside from liking everything to be “bigger” those in the older age group also preferred simpler web designs.
