Smartphone and tablet strain our joints and muscles according to recent study


Researchers from Saarbrucken are conducting studies to shed more light onto how smartphones and tablets usage put strain on our bodies.

In what could be considered an ambitious project, computer scientists at Saarland University are attempting to map out the point(s) of stress people undergo while using their smartphone and tablets.  To accomplish this, the team developed a tool that combined several different components, including three-dimensional motion capture (a specialized suit) and biochemical simulation (computer simulation program), to track and generate data for their experiments.

Using parameters such as the angles at which the joints move and the forces acting on the joints, the group were able to create models that can predict which parts of the body are subjected to the most stress while using a tablet or smartphone.


“The model allows us to see precisely which part of the body is subjected to the greatest loading when a particular movement is performed, and so we can determine whether, say, the upper arm muscles or elbow are under particular strain,” said Myroslav Bachynski, a PhD student at the university.

According to the team, data generated from various simulations have led the team to believe that left to right and top to bottom hand gestures on smartdevices put less strain on the body when compared to the opposing movements.

Ultimately, the goal of the research is to give engineers and IT professionals useful information on the way the human body operates relative to smartphone and tablet usage.  The study also has implications in the health sector as companies are in dire need of technologies that will improve the design of tools and work environments.
