Provide a cursor showing clearly the selected target. It should be obvious to older adults what can be selected and what cannot.
Older adults tend to lose attention frequently, so in a user interface it is important identifying which element on the screen is being currently selected. Older adults also presenting a reduced working memory causing difficulty in the tasks that involving reasoning, which include the ability to understanding what the user can and cannot do, and the ability to remembering the steps required to complete a task. Because of this, in a user interface should be obvious what can be selected and what cannot by older adults.
