The Tetra project ExpertGaze is investigating how measurements of behaviour, visual attention and stress levels during the execution of a task, can be of added value for building competences and supporting people in the performance of their jobs. Furthermore, it is investigated how measurements of experts can contribute to the training, support and/or accreditation of non-experts.The goal of the ExpertGaze project is to translate the already available and accumulated knowledge about measurement technologies into concrete challenges that our field partners, but also the wider labor market has to deal with.
