Over the last 10 years, production systems have been shaped by Industry 4.0, which drives digitalisation and networking in real time. Industry 5.0, on the other hand, focuses on human-centred technologies that support employees and enhance their skills. Personalisation plays a major role here, especially in manual assembly and testing workstations. The challenge is to adapt workstations individually without compromising standardisation. Eye tracking is used to investigate influencing factors at the workplace and analyse the data using software. This research forms the basis for a concept for the personalisation of manual workstations.
