New mobile technologies like tablet PCs and smartphones are used privately as well as in the office, and increasingly also in production and logistics. This creates new opportunities and challenges for OSH. The present scoping review provides an overview of current scientific knowledge (until January 2016) about physical stress and strain associated with the use of tablet PCs and Smartphones.

The 41 scientific studies extracted for the review were mostly laboratory research focused on biomechanical parameters. Only two studies dealt with the visual impact of using smart devices. Based on the reported results, an elevated risk of physical stress, especially for the neck and the thumb can be stated. Trying to reduce glare and reflections on the devices, using the own body for shading, further contributes to unfavourable postures. Texting with repetitive, very fast movement increases the risk of tendinopathy.

Basically, tablets and smartphones should be used rather briefly. Because mobile devices are used under diverse lighting conditions, they should be equipped with lowreflection displays. The optimal combination of weight and necessary screen size should be based on the task at hand. For longer periods, accessories like an external keyboard may help to improve posture and comfort. Further research into the use of tablet, smartphone and other smart devices seems necessary.
