DescriptionMixed reality applications allow users to experience both physical and digital worlds simultaneously. However, limited research compared multitasking performance in these two worlds with different difficulty levels. The current study investigated the task difficulty effect on mixed reality multitasking performance. A total of 36 participants completed eight experimental sessions and were tested on four measures, NASA-TLX, accuracy, priority, and hand use. The results indicate that four out of six NASA-TLX subscales were significant. The differences in which participants prioritized which world task were found to be insignificant. Such a study can potentially enable mixed reality application designers to predict their users’ performance based on a selected difficulty level.
