Third Wizard of Oz Test in the Welding Lab

On the 19th of June 2018 the third Wizard of Oz test in the welding lab took place. This time, we did not focus on the interaction with the welding machine during the welding process but on adjustments and parameter changes before the actual welding process starts. We tested a new Voice User Interface Design, concentrating on comprehensibility, learnability and User Experience. Again, several instruments like UEQ, NASA TLX but also open questions were used.
