Personal trainer for healthy sitting

The only thing that can break the vicious circle of pain and poor sitting posture is active, conscious movements while sitting and standing. To support this solution in a targeted manner, researchers at the Fraunhofer Institutes for Industrial Engineering IAO and for Silicate Research ISC have devised a personal trainer for healthy sitting and movement. Fraunhofer ISC developed the technology, while Fraunhofer IAO developed the product.
