Changes and innovations are needed in the area of instruction and control of employees to perform reliably and cost effective in order picking. The information must be easily accessible - communicated in a succinct way to overcome intellectual, socio-educational as well as language barriers. This case mainly focuses on conducting, research in the field of technical support by assistance systems for impaired people and people with altered performance, but also for people without restrictions. This paper aims at presenting the prototype of a new assistance system for manual order picking. In addition, the prototype was evaluated in a user study involving 24 people with three other methods (pick-by-paper, pick-by-light, pick-by-display), which represent the current state of the art. We report about the number of errors, the task completion time and the cognitive workload for all four approaches. The results show that this new kind of assistance system can have benefits, particularly in the area of error prevention and workload.
