Interruptions play an important role in hospital settings. Head-worn displays are increasingly used in addition to conventional monitors to display information to doctors. In our study we investigated whether using such displays could have an effect on the interruption lag (the time needed to go back to working on a primary task after an interruption). We disrupted participants during a work task on a conventional monitor with a secondary task which was displayed on different head-worn displays. Our hypotheses were based on the Memory for Goals Theory by Altman and Trafton.
