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.
