G107 – The text should be double spacing between the lines.

Standard

Guideline:

The text  should be double spacing between the lines.

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.

G61 – Use left-aligned text.

Standard

Guideline:

Use left-aligned text.

Guideline Description:

The text alignment should be left-aligned, due to the justified text does not maintain the optimized spacing between letters and words, and the older adults are accustomed to reading left-aligned text.

Avoid:

Text justified.

Example:

exemplo G61

An example of a left-aligned text and example of a justified text.

G58 – Use a very large font type.

Standard

Guideline:

Use a very large font type.

Guideline Description:

Visual acuity is a visual impairment common among older adults. It is important ensuring that the text added in a user interface is legible and readable, through the use of large and sans serifs font types, which are easier to read on the screen. Ideally, the interface should contain an adjustment mechanism.

Example:

examplo G58

An example of an application with adjustable font type.
