4.2. Functional Performance Statements
The statements set out in clause 4.2 are intended to describe the functional performance of ICT enabling people to locate, identify, and operate ICT functions, and to access the information provided, regardless of physical, cognitive or sensory abilities. Any ability impairments may be permanent, temporary or situational.
Where ICT provides visual modes of operation, some users need ICT to provide at least one mode of operation that does not require vision.
Notes: Audio and tactile user interfaces may contribute towards meeting this clause.
Where <abbr title="Information and Communication Technologies">ICT</abbr> provides visual modes of operation, some users will need the ICT to provide features that enable users to make better use of their limited vision.
Notes:
- Magnification, reduction of required field of vision and control of contrast may contribute towards meeting this clause.
- Where significant features of the user interface are dependent on depth perception, the provision of additional methods of distinguishing between the features may contribute towards meeting this clause.
- Users with limited vision may also benefit from non-visual access (see clause 4.2.1).
Where ICT provides visual modes of operation, some users will need the ICT to provide a visual mode of operation that does not require user perception of colour.
Notes:
Where significant features of the user interface are colour-coded, the provision of additional methods of distinguishing between the features may contribute towards meeting this clause.
Where ICT provides auditory modes of operation, some users need ICT to provide at least one mode of operation that does not require hearing.
Notes:
Visual and tactile user interfaces may contribute towards meeting this clause.
Where ICT provides auditory modes of operation, some users will need the ICT to provide enhanced audio features.
Notes:
- Enhancement of the audio clarity, reduction of background noise, increased range of volume and greater volume in the higher frequency range can contribute towards meeting this clause.
- Users with limited hearing may also benefit from non-hearing access (see clause 4.2.4).
Where ICT requires vocal input from users, some users will need the ICT to provide at least one mode of operation that does not require them to generate vocal output.
Notes:
- This clause covers the alternatives to the use of orally-generated sounds, including speech, whistles, clicks, etc.
- Keyboard, pen or touch user interfaces may contribute towards meeting this clause.
Where ICT requires manual actions, some users will need the ICT to provide features that enable users to make use of the ICT through alternative actions not requiring manipulation or hand strength.
Where ICT products are free-standing or installed, the operational elements will need to be within reach of all users.
Where ICT provides visual modes of operation, some users need ICT to provide at least one mode of operation that minimizes the potential for triggering photosensitive seizures.
Some users will need the ICT to provide features that make it simpler and easier to use.
