G64 – Avoid forcing users to read at very close distances.

Standard

Guideline:

Avoid forcing users to read at very close distances.

Guideline Description:

Older adults may suffer of presbyopia, characterized by a progressively diminished ability to focus on near objects. This impairment can be reduced through the use of glasses. So, for this reason do not force users to read at very close distances.

Example:

exemplo G64

An older adult with presbyopia symptoms.

G63 – Give them time to read. Older adults usually read more slowly (than younger adults).

Standard

Guideline:

Give them time to read. Older adults usually read more slowly (than younger adults).

Guideline Description:

In general older adults have low literacy level, so they need more time to reading than younger adults. It is important to give them time to read and interpret the information presented. For example the use of popups that disappear after  certain  number  of seconds should be avoid, once  the older adult may not have the enough time to read.

Example:

exemplo G63An older adult reading elements of a nutrition application in a touch-screen device.

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.

G53 – Don’t forget older adults did not grow up using computers, “the odds are stacked against them”.

Standard

Guideline:

Don’t forget older adults did not grow up using computers, “the odds are stacked against them”.

Guideline Description:

The older adults did not grown using computers, for this reason, in general they have difficulties in using them and consequently they are not familiar with many metaphors used in these systems.

Example:

examplo G53

An older adult using a computer.

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.

G49 – Give them time to learn.

Standard

Guideline:

Give them time to learn.

Guideline Description:

The learning capability of the older adult is more slower than a young adult, due to their cognitive changes, especially in the decrease of short-term memory, responsible by  human learning.

Example:

examplo G49

An older adult, learning how to use a multi-touch tabletop.
