G113 – Minimize the number of steps it takes to reach a given screen.

Standard

Guideline:

Minimize the number of steps it takes to reach a given screen.

Guideline Description:

The steps should be simple and number of steps needed to achieve a given screen should be minimized, fostering a good navigation. An useful way of presentation is through of the use of a hierarchy and grouping of information into meaningful categories, focusing only the most relevant items.

Avoid

Complex, multi-step process.
Procedures inconsistent with established practice.
A deep hierarchy.

Example

example g113Examples of well-designed hierarchy menus.

G102 – Do not have a deep hierarchy and group information into meaningful categories

Standard

Guideline:

Do not have a deep hierarchy and group information into meaningful categories.

Guideline Description:

The use of a deep hierarchy to show information in the interface is not recommended for older adults, however  the use of a hierarchy with essential elements can be considered. The information should be grouped using meaningful categories giving obvious navigation cues.

Example:

example g102

An example of an user interface using meaningful categories giving obvious navigation cues.

G85 – Show the current location clearly.

Standard

Guideline:

Show the current location clearly.

Guideline Description:

Decreasing of short-term memory of older adults may cause forgetfulness what they wanted to achieve when changing screen. Because of this, should be indicated the current location.

Example:

exemplo G85

An example of an application that shows the current location, in this case ” My Shows”.

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.

G57 – Avoid irrelevant information.

Standard

Guideline:

Avoid irrelevant information.

Guideline Description:

Older adults have difficulty dealing with simultaneous tasks or multi-tasking, due to their declining in working memory. This decline is also responsible for a low capability in ignoring irrelevant information, so should be avoid displaying irrelevant information.

Example:

examplo G57An example of an application without irrelevant information.

G56 – Reduce the demand on working memory by and supporting recognition rather than recall provide fewer choices to the user.

Standard

Guideline:

Reduce the demand on working memory by supporting recognition rather than recall and provide fewer choices to the user.

Guideline Description:

In general, normal aging process declines working-memory, due to this factor it is important designing for recognition than recall, in order to reducing these identified limitations. Presenting similar contents in the same way is recommend in the design of the user interface, for example in the menus.

Example:

example g56

Similar appearance in the menus promotes  recognition rather than recall.

G52 – Make use of behaviors developed by older adults to cope with memory loss.

Standard

Guideline:

Make use of behaviors developed by older adults to cope with memory loss.

Guideline Description:

Losing of memory essentially the short-term memory, implies the use of some mechanisms to remembering, for example, note-taking. The use of these mechanisms should be encouraged.

Example:

examplo G52

An older adult taking notes during the use of a computer.
