G70 – Maintain consistency in the user interface. Screen layout, navigation and terminology used should be simple, clear and consistent.

Standard

Guideline:

Maintain consistency in the user interface. Screen layout, navigation and terminology used should be simple, clear and consistent.

Guideline Description:

The positioning of the interface elements on the same position in the screen will help the older adults, once older adults have reduced short-term memory. Center of the screen is privileged to give emphasis, increasing the likelihood of user notice the information.

Example:

example g70

Examples of consistent menus with a similar visual appearance.

G69 – Avoid the use of scroll.

Standard

Guideline:

Avoid the use of scroll.

Guideline Description:

Conventional user interfaces  resort often  use  of  scrolling  to  display  content  that  cannot  be displayed  on one screen. In  touch-screen interfaces used by the elders this technique should be avoid, not only by their declining working memory that may cause the losing of the context of the task but also because using scroll bars implies hand-eye coordination may be difficult to performing by some older users.

Example:

exemplo G69

An example of scrolling use in a touch-screen interface that should be avoid.
