Specification and simulation of task models with VTMB

Abstract

In this live demonstration we present the Visual Task Model Builder (VTMB) tool [1]. Using this tool the user can create and modify rich task models, containing a hierarchical task structure, temporal relations between tasks, conditions of task execution, and objects involved while performing a task. Based on precise semantics the model can be simulated for validation with the future user and the user interface designer. Additionally, it provides the basis for the transformation of the task model into a working dialogue model.
