- abstract: influence of interruptions on different types of decision-making tasks, and ability of info. presentation formats to alleviate them; interruptions facilitate performance on simple tasks, inhibiting performance on complex tasks; spatial presentation formats able to mitigate effect of interruptions while symbolic formats were not;

Storch N. Does the user interface make interruptions disruptive? A study of interface style and form of interruption.

- abstract: looked at how unexpected interruptions disrupt computer user performance, whether there is a significant effect due to style of user interface (GUI vs CUI); performance in data entry of personnel database, 3 different forms of interruption (telephone, visitor, on-screen interruption - subject must answer simple question); eye motion data analysed in terms of amount of time and avg. duration of eye fixations on screen; result: screen interruption was disruptive, telephone was not, walk-in intermediate disruption; lower performance directly related to looking more at screen; duration of interruption weakly correlated to performance; another possible explanation for disruptiveness of screen interruption vs. telephone interruption was similarity by modality; GUI makes it easier to work through non-similar (phone, walk-in) interruptions;
