The elements of universal design.

Universal Design elements	Descriptions
Alignment	The alignment of elements in an interface design should be in line with each other
Chunking	A technique where the information is combined into specific pieces (chunks) so that the information is easy to process and remember
Colour	Limit the use of colours to at least five colours depending on the complexity of the design. Do not use colour as the only way to convey information
Consistency	The consistency: the same section is presented similarly
Control	The control level provided to a system suits the abilities and experience of the user
Readability	The readability of certain information is based on word size, contrast, and space
Mapping	The relationship between control over a system and its effects. Good relationships can facilitate the use of a system
Ockham’s razor	The interface should be simplified, and any unrelated element needs to be reduced
Performance load	Performance load consists of cognitive load and kinematic load. The cognitive burden can be reduced with minimal design, while kinematic load involves the burden of physical activity by reducing an action or movement
