Wizard-of-Oz Test in the Welding Lab

To be better able to consider welders’ needs and their natural behavior during their daily tasks and tailor the alternative interaction solutions to their preferences, the project team conducted a wizard-of-oz test with several well-experienced welders in November of 2017. The welders worked together in pairs, one performing the welding task, the other one simulating the future alternative interaction solution. Further, we gathered insights related to task load, user experience and personal impressions and suggestions via Nasa TLX, UEQ and a questionnaire with open questions. The related findings will be essential for the further development.
