User interface design specification for household electrical appliances for older persons
1 Scope
This standard specifies the user interface elements, design requirements and design evaluation of household and similar electrical appliances (hereinafter referred to as the “appliances”) that take into account the needs of old persons.
This standard is applicable to the easy-use design of appliances that meet the needs of older persons.
Note 1: This standard does not involve control devices such as mobile phones and infrared rays, and control methods such as gestures and voice.
Note 2: Older persons involved in this standard are those who can take care of themselves, but because of ageing, there are some obstacles for them in using appliance that meet the conventional technical requirements. Some older persons lose the ability to use appliances due to physical disability or mental disorder, therefore their needs will exceed the guidance scope of this standard.

GB/T 36934 Design guidelines for household electrical appliances for older persons
3 Terms and definitions
For the purposes of this standard, the following terms and definitions apply.
3.1
older persons
people over 60 years old (including 60 years old)
3.2
user interface
product element used to control a product and receive its status information
Note: The instructions displayed persistently on the product may be regarded as a part of the user interface.
[GB/T 32265.1-2015, 3.21]
3.3
interaction
two-way information exchange between users and appliances
Note: It is a revision of Definition 3.13 in GB/T 32265.1-2015.
3.4
impairment
problems with human functions or tissues, such as severe decline or loss of functions, which may be temporary (as caused by injury) or permanent, and may change over time, especially as the functional degradation caused by ageing becomes more obvious
[GB/T 20002.2-2008, 3.4]
3.5
easy-use design
design that focuses on elderly users who can take care of themselves and have no serious physical and mental obstacles, to make them use the product design easily
4 User interface elements
4.1 General
The user interface elements in this standard mainly involve:
a) interaction components such as control keys and control panels;
b) information presentation;
c) functional logic.
4.2 Control key
4.2.1 Rotary knob
Comprises different types of knobs, such as cylindrical knobs and grip knobs which may have independent positions or continuous settings or both, as shown in Figure 1.
They may have push function to confirm selection or hide control keys.
The selection wheel in Figure 2 is a special rotary control key. It has a push function to confirm the selection.
Figure 1 Cylindrical and grip knobs
Note: Double arrows indicate the operation direction.
Figure 2 Thumb wheel selection
4.2.2 Sliding key
Sliding keys may be divided into the following categories:
a) the small movable part slides in a certain groove to adjust the setting between the defined starting points, which usually contains a shaft (see Figure 3). They may have independent positions, continuous arrangement or both.
b) The graphic control key is placed in a graphic track, and when it is touched, it can be dragged to adjust the setting between the defined starting points. The control key may be moved along a certain axis in linear direction or circular direction. With this kind of control key, the user may also touch any point along the graphic track and directly move the indicator/control key to the setting position.
c) The handle lever is a special sliding key
Example 1: Steam setting key on steam electric iron.
Example 2: Bread handle lever on bread toaster
