G104 – Language should be simple, clear, uses the active voice and uses positive phrasing.

Standard

Guideline:

Language should be simple, clear, uses the active voice and uses positive phrasing.


Guideline Description:

The use of simple language  in a user interface for older adults, is important for a good understanding, otherwise they may have difficulties in the interpretation.

Example:

example g104An user interface example with simple language.

G81 – Read speech at a consistent and reasonable pace.

Standard

Guideline:

Read speech at a consistent and reasonable pace.

Guideline Description:

Using fast speed reading, older adults with hearing impairment may not understand, on the other hand, using slow speed reading, older adults may cause problems processing information because of decrease in short-term memory. For these reasons, reading for an older adult, should use a consistent and reasonable pace, according to listener capabilities.

Example:

exemplo G81

An example of reading for an older adult, which should use consistent and reasonable pace.

G80 – Create speech that is redundant, semantically well structured.

Standard

Guideline:

Create speech that is redundant, semantically well structured.

Guideline Description:

The use of redundancy i.e. construction of a phrase that presents some idea using more information, in order to enabling the understanding of the idea transmitted and semantically well-structured phrases, increase the speech intelligibility by older adults.

Example:

exemplo G80

During a dialogue with older adults, the use of well structured and redundant messages increase speech inteligibility.

G79 – Do not use synthetic speech unless it resembles natural speech correctly.

Standard

Guideline:

Do not use synthetic speech unless it resembles natural speech correctly.

Guideline Description:

The use of synthesized speech in the user interface may be not understandable. Older adults appreciate more the contextual and nonverbal aspects of speech such as rhythm and tone, if the synthesized speech does not contemplate these characteristics, communication is likely to be harder.

Example:

exemplo G79An example of an application using synthesized speech, whose its use should be avoid with older users.

G78 – Use male voices for delivering auditory information.

Standard

Guideline:

Use male voices for delivering auditory information.

Guideline Description:

Older adults have in general some limitations in hearing of high frequency sounds. Women and children have a higher pitched voice, and for this reason should not be used for delivering  auditory information. Male voices are most appropriate to this end.

Example:

exemplo G78
An example of an application with option of the use of a female and male voice. In the case of older users, the male voice is preferable.

G55 – Present a single message in a single screen.

Standard

Guideline:

Present a single message in a single screen.

Guideline Description:

A screen of an application should not be overfilled with information. Ideally, a single message should be displayed in a single screen.

Example:

example guideline g55

An example of an application using a single message in a single screen .

G54 – Use simple phrasing.

Standard

Guideline:

Use simple phrasing.

Guideline Description:

Elderly people group presents in general a low academic education level, for this reason,  the language employed in the user interfaces should be as simple as possible, in order to attenuating  perceptual  and cognitive difficulties.

Example:
