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.

G46 – The lack of tactile user feedback also affects the user experience of data input on multi-touch interfaces.

Standard

Guideline:

The  lack  of  tactile  user  feedback  also  affects  the  user experience  of  data  input  on  multi-touch  interfaces.

Guideline Description:

The  lack  of  tactile  user  feedback (Guideline 41) also  affects  the  user experience  of  data  input on  multi-touch  interfaces, for example, typing in a virtual keyboard.

Example:

examplo G46

An user typing in a virtual keyboard with visual feedback.

G7 – Animations alone are not effective in signaling synchronous and asynchronous events on the interfaces and should be accompanied by redundant information in other modalities.

Standard

Guideline:

Animations alone are not effective in signaling synchronous and asynchronous events on the interfaces and should be accompanied by redundant information in other modalities.

Guideline Description:

Animations can be used in the interface to informing the user in perceiving and understanding both system’s responses, synchronous events (e.g. the automatic storing of a copy of a sent postcard in the drawer) and asynchronous events (e.g., the reception of a post card) in the case of an application to send and receive post-cards. The animations alone used are not enough to transmit system status to users and additional complementary information is needed.

Example:

example_g7

Mobitable is a system to send and receive post-cards. In this system it has been verified that the use of animations alone is not enough to transmit to user the system status.

G6 – Due to large variability in touch performance by elderly people (due to age, health-related issue, etc.) the setting of the time parameters of gestures is of paramount importance, to promote a better adaptation.

Standard

Guideline:

Due to large variability in touch performance by elderly people (due to age, health-related issue, etc.) the setting of the time parameters of gestures is of paramount importance, to promote a better adaptation.

Guideline Description:

The setting of the time parameters of gestures is a crutial feature, in order to promote a better adaptability of the interface, due to a large variability in touch performance by elderly people (due to age, health-related issue, etc.).

Example:

example_g6

This example illustrates the setting of  time response of the gestures.
