Guideline: Consider a tilted or adjustable display, can ease the interface visualization. Guideline Description: The use of a tilted or adjustable display attenuates the motor and visual impairments of the older adults. Example: An example of use of a tilted display by an older user. Illustration adapted from An Exploratory Study of a Touch-Based Gestural […]
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 […]
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 […]

Guideline: Use only one type of input device. Guideline Description: The use of different input devices might increase the difficulty to the user. Example: An example of an application using pen-based interaction. This interaction type can be difficult to performing by some older adults. Illustration adapted from An Exploratory Study of a Touch-Based Gestural Interface […]
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: An example of an application using a single message in a single screen . Illustration adapted from An Exploratory Study of […]
Guideline: Isolate what you want to test. Guideline Description: The interaction of the older adults with a system can be affected by a set of factors namely physical factors, cognitive factors and motor issues factors. To identify the origin of problems that affects the interacting it is necessary isolate test variables. For example to evaluate […]
Guideline: Iconic gestures are very engaging. Guideline Description: An iconic gesture is a gesture that visually and analogically represents its meaning; these gestures have a hedonic quality that are enjoyed by older users. Example: ‘X’ gesture , ‘L’ gesture. Example: “X” gesture and “L” gesture are examples of iconic gestures. Source: An Exploratory Study of […]
Guideline: In drag gestures, the “natural” version should be implemented: the object should stay where it has been left rather than flying back to its initial position. Guideline Description: In the use of drag gesture in the manipulation of an interface, the “natural” version of this gesture should be implemented, i.e. when the contact is […]
Guideline: Do not overload the same object with actions performed by a tap and by a drag gesture. Guideline Description: The same object should not be overlapping with actions performed by a tap and by a drag gesture. In case of insufficient pressure or of false starts these two gestures may be easily confused. Example: […]
