The technology to support Augmented (AR) and Virtual Reality (VR) applications are considered increasingly mature for a broader, productive application in corporate environments. As yet, they have been underused, among other reasons, due to doubts about the acceptance and productive performance by employees. This paper presents a study that collected standardised measures for usability (SUS) and task load (NASA-RTLX) across nine different AR and VR use cases developed specifically for industrial and corporate settings. The resulting prototypes were tested with real potential users as well as with students. The results show that the participants had a positive opinion of the prototype´s usability and did not register an unusually high workload. According to the results, factors such as age and gender do not appear to affect usability perception, though they still affect the task-load perception. The study concludes that with human centred design and suitable support on implementation, AR and VR can be successfully used in corporate setting.
