Visual design considerations
When creating a human-computer interface, there are several visual design considerations that the development team must take into account, such as the use of colour and the style of typography.
​
You need to know how each visual design consideration is used when designing human-computer interfaces and how these interfaces can be improved to be more effective.
As with most topics, it is also vital to consider how client requirements may impact changes related to visual design, for example, using larger text for users with visual impairments.

Visual Design Considerations
Colours are used to define the visual appearance of the interface. This includes background colours, button colours, icons and text.
Interaction refers to how users control or respond to the system through input methods like clicking, tapping, swiping, typing or speaking.
Location hierarchy is about the placement and organisation of interface elements based on importance.
Messages are displayed to provide feedback, guidance or explanations - such as confirming actions, explaining errors or offering help.
Typography includes the choice of font types and the size, spacing, weight (boldness) and alignment of text.
