Offering multiple interaction points that all look the same, can result in a user not knowing what is expected of him/her. Therefore, there is the possibility to classify the interaction points with symbols, as shown in the figures below.
A symbol is a certain shape and color, which is assigned to the interaction point. When a user sees a certain symbol, he or she can immediately determine what will be expected on the basis of the shape and color. It is possible to shape and create symbols yourself, but there are also three pre-programmed symbols available:
- a yellow triangle indicates that a user will receive a certain instruction
- a green square indicates that a user will receive information
- a blue circle indicates that the user will receive a test.
