Wireframing, Prototyping, Mockuping – What’s the Difference?
Prototypes are used to their full potential in user testing. Such a simulation of the final interactions forms great material to check the usability of the interface, before the development actually begins.
Prototypes usually aren’t the best documentation you can imagine, since they force the „reader” to take some effort to understand the interface. On the other hand, a prototype is the most engaging form of design documentation as the interface is tangible and straightforward.
