Design Principles
User Expectations
Colour
Humans generally have a perception of different colours and when we see a colour on the screen wee are instantly able to determine what it means.
Symbols
From a very young age we recognise different shapes and symbols and can give them meaning
Visuals
We have learned in this lesson that people instantly form an idea in their head as soon as they see a certain colour or hear a certain sound.
Sounds
Humans also have perceptions of sound. Oft¬en, as soon as we hear a sound, we can distinguish what it means and then react to it.
Intuitive design
.
Graphics to illustrate what buttons do
When we see an icon image on the screen, we form an idea about what the icon will do when we click on it. It is important that the icon image should match the action that users have envisaged.
Helpful pop-up messages
When you need to inform the user that an error has occurred, it is good practice to use pop-up messages. These are messages that appear in a small window with information telling the user what has gone wrong
Easy reversal of actions
We all know how frustrating it can be when we make a mistake and are unable to correct it.
Help features
User interfaces should contain enough help to allow the user to successfully complete tasks.
Ensure consistency
Another method of making sure your user interface is intuitive is ensuring that each screen has a consistent design.
Keeping the user engaged
Grab attention
Sometimes, you need to grab the user’s attention. For example, the user needs to be warned if they have made an error when typing into a form
Uncluttered screens
Lebels
Do not automatically assume that the user will know what every part of a user interface is or how to use it.
Tip Text
Default values
A default value, also known as a predetermined value, is something that is already on the user interface before the user opens it.
Autofill
