ConcurTaskTrees (CTT)
is a notation for task model specifications useful to support design of interactive applications specifically tailored for
user interface
In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine f ...
model-based design.
The main features of ConcurTaskTrees are:
* Hierarchical structure, which provides a large range of granularity in describing large and small task structures;
* Graphical syntax, which reflects the logical structure in a tree-like form;
* Concurrent notation, which supports flexible ordering of the tasks to perform.
In
Human-Computer Interaction, task models indicate the logical activities that an application should support to reach users’ goals. There are also methods that indicate how to derive user interfaces for different platforms from ConcurTaskTrees specifications
The last evolution has been the introduction of preconditions.
It has been used both in academia and industry, especially by companies with an interest in
