Zusammenfassung
This paper reports results from a controlled experiment (N = 50) measuring effects of interruption
on task completion time, error rate, annoyance, and anxiety. The experiment used a sample of primary
and peripheral tasks representative of those often performed by users. Our experiment differs
from prior interruption experiments because it measures effects of interrupting a user’s tasks along
both performance and affective dimensions and controls for task workload by manipulating only the
time at which peripheral tasks were displayed – between vs. during the execution of primary tasks.
Results show that when peripheral tasks interrupt the execution of primary tasks, users require from
3% to 27% more time to complete the tasks, commit twice the number of errors across tasks, experience
from 31% to 106% more annoyance, and experience twice the increase in anxiety than when
those same peripheral tasks are presented at the boundary between primary tasks. An important
implication of our work is that attention-aware systems could mitigate effects of interruption by
deferring presentation of peripheral information until coarse boundaries are reached during task execution.
As our results show, deferring presentation for a short time, i.e. just a few seconds, can lead
to a large mitigation of disruption.
