A mental model represents a person's thought process for
how something works and is based on their experiences
and assumption of how certain concepts works
In relation to ICT it includes the user experiences with
computers and real life experiences that may link to
computers
No experience in ICT => mental model entirely based of real world
User interface needs to be designed with concepts that
are used in the real world so their user's real world
experience can aid their learning of the computer
system.
E.g Files storing documents and related files can be kept together in a folder.
Unwanted files can folders can be put in the recycling bin, but can be retrieved later.
Applying mental model
Consider who is using software and their experiences
Have multiple ways of achieving the same task if
users have varying experiences
Consistent system means users can develop
mental model fast. Can remember how items
are position and tasks are done
Not try to be too different from other software. e.g have
home in the bottom left and file in the top left corner
Visual prompts, e.g. Bold symbol in bold, italic
symbol in italics, underline sysmbol underlined.
