Abstract: A system for assisting a user in fulfilling a task, the system comprises a human interface unit for communicating with the user, a task input unit configured to obtain unstructured knowledge source data on the task, and a processor. The processor interprets a user input obtained by the human interface unit. The processor further analyzes the obtained unstructured knowledge source data for generating an internal representation of the task and monitors a task progress in performing the task by interpreting at least one of the user input and image data. The processor generates a support signal based on the generated internal representation and the monitored task progress and outputs the generated support signal, wherein the support signal comprises information on manipulating at least one object or information how to perform the task.
