Recently I enrolled to HCI course, and there was mentioned that WIMP (windows, icons, menus, pointer) is a token-based interactive system. Does anyone knows what does token-based mean in WIMP system, since "token-based" was implied, because nonWIMP is (I guess) seen as non-token-based.

  • I have no idea what "token-based" should mean in this context. Can you provide a source? – virtualnobi Sep 5 '18 at 7:02

Well, WIMP is a very old term, I'm a bit surprised it's still in use.

Anyways, you could say most digital systems using graphical interfaces are WIMP. As a matter of fact, the term used to replace WIMP is GUI.

With that being said, a token-based interactive system is a system that reacts to an user token (interaction). See an UML diagram below:

enter image description here

In this model, the system reacts in 2 ways: token-based or location aware.

As the name implies, location aware means the system reacts to user's location in an automatic way (for example, maps or apps that read your location).

In opposition to the above, token-based requires some specific interaction which results in a token sent to the system, hence the name.

If you need more information, you can read this research paper with examples (from which I extracted the UML model): Formal notation for modeling location-aware and token-based interactive systems
