In this paper, we describe an experimental study that investigated the effects of electronic work instructions and AR based instructions (projected work instructions) on productivity, product quality and human operator workload. In a simulated assembly task, projected instructions on the work spot and operator guidance picking the correct component lead to significantly higher productivity and quality rates compared to instructions presented on a screen. Remarkably, at these higher levels of performance, the work load on the operator was not increased, but instead significantly decreased.
