ConcurTaskTrees

CTT (ConcurTaskTrees) [1] is a notation for task model specifications useful to support design of interactive applications.

The main features of ConcurTaskTrees are: 

   * Hierarchical structure
   * Graphical syntax
   * Concurrent notation

In Human-Computer Interaction, in the field of Model-Based User Interface and task analysis, task models indicate the logical activities that an application should support to reach users’ goals.

ConcurTaskTrees has been mapped into Unified Modeling Language [2].

Tool Support

The editing and analysis of task models is supported by the ConcurTaskTrees Environment (CTTE) [3]. The executable code is publicly available and free to download.
