A. User interface design requirements
The design and implementation of the user interface (UI) is a crucial part of the project.
The UI is the “front side” of the
project and have a central role in its achievement. In general,
the user knowledge is defined by the UI. The type of users is an
important parameter when we design the UI, for example,
through favourable experiences, users can appreciate a product,
while an incompetent performance will most generally lead
them to dismiss it. When designing the UI for “World of Kids”
we developed a smooth design Methodology [13] to create a
practical and user-friendly series of applications that understand
the mindset of children with ASD. Autistic children, for
example, prefer predictability and consistency in their
environments, and slight changes can discomfort and/or stress
the child [14].
