As the complexity of work tasks rises for maintenance workers in modern production facilities, new technologies will be required to support and integrate the service worker of tomorrow. This paper gives an insight into an ongoing research project examining the potential of smart glasses used as a component of assistant systems for workers performing maintenance tasks in an industry 4.0 context. A human centered design process is used to identify the needs of workers and to specify requirements for the assistant system being developed. Thereby, the maintenance of a CNC lathe is used as an example and assistant functions were developed for one specific maintenance task. The architecture of the assistant system proposed in this paper is based on an analysis of the work system including the tasks of the maintenance worker. Finally, the implementation of a first prototype, using state-of-the-art augmented reality smart glasses, is described.

In the future, Uninhabited Aerial Vehicles (UAVs) will be part of both civil and military aviation. This includes co-operative mission accomplishment of manned and unmanned assets with little manpower being available for UAV guidance. So, UAVs need to be able to accomplish tasks with a minimum of human intervention and possibly in co-operation with other UAVs or manned aircraft. This paper presents artificial cognition as approach to co-operative capabilities of UAVs. They are guided by so-called Artificial Cognitive Units (ACUs) being capable of goal-directed behavior on the basis of understanding the current situation. Prototype evaluation results show the capability of suchlike co-operative ACUs to yield human-like rationality and the ability to act as peers in a human-ACU team.
