Children’s development aspectsChildren’s design elementsDescriptions

CognitiveVisual design(i) The icon used should represent an easily recognisable, interactive, and not complex visual
(ii) The icon should be large so that children can click it easily
(iii) Use graphic metaphors. For example, using an interface that looks like a children’s storybook. Children will also sense the object as if they are in the real world
Text(i) Reduce text usage due to different levels of children’s literacy
(ii) Use simple instructions that are suitable for the children’s age
Interaction styles(i) Provide immediate feedback. Children are usually impatient and need immediate feedback to show that every action impacts
(ii) The interface should provide scaffolding and guidance to assist children in completing their tasks
(iii) Use audio and animation with specific functionality
(iv) The interface should display the system status and facilitate children’s navigation
(v) Use direct manipulation where each input device has a direct effect on the screen
Menu(i) Menus should be used easily, and there should be no submenus

Physical (motor skills)Indicators(i) Interaction for the mouse should be easier. For example, a one-click interface is easier than using a two-click
(ii) Touch screen is appropriate for children
(iii) The dragging movement must be done by clicking on the object to attach it to the pointer and then clicking again and releasing it to the desired location
(iv) The interface should not cause children to hold the mouse button for a long duration
