About: ConcurTaskTrees

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

ConcurTaskTrees (CTT) is a notation for task model specifications useful to support design of interactive applications specifically tailored for user interface 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. Some studies have investigated its usability

dbo:abstract
  • ConcurTaskTrees (CTT) is a notation for task model specifications useful to support design of interactive applications specifically tailored for user interface 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 Enterprise resource planning (ERP) and safety-critical systems (e.g. air traffic control systems). [1]. It has been considered in the World Wide Web Consortium (W3C) for standardization of task models [2]. Some studies have investigated its usability ConcurTaskTrees has been mapped into Unified Modeling Language. (en)
