Smart palletisation. Cognitive ergonomics in augmented reality based palletising

Palletisation is recognized as a central logistics process which largely depends on employee's performance and expertise. To assess potential advantages of augmented reality (AR) in palletisation, an AR device was compared with a conventional paper-based pick list and a tablet computer. Usability measures show that the usability of the tablet computer surpassed the AR device and the pick list, whereas task load measures suggests that the AR device provides the less strenuous method to assist participants in palletisation. Thus, we conclude that AR devices are appropriate to assist logistic workers in palletising, however usability has to be improved considerably.
