Snookered by an interruption?: use a cue
نویسندگان
چکیده
When routine tasks are interrupted, erroneous slips become more likely. Expertise is no defence against these kinds of errors but visual hints can alleviate such negative effects in computer interfaces. We compared previous-action cueing with next-action cueing, measuring the effects on error rate, and found that both approaches were statistically equivalent in helping to mitigate the disruptive effects of interruptions. Following an interruption, a cue should be displayed highlighting the last action performed by the user – a trivial operation for software applications.

Huh , what was I doing ? How people use environmental cues after an interruption
We examine the effect of environmental cues on being interrupted while performing a task. We conducted an experiment in which participants, after an interruption, received either a blatant environmental cue of their previous action (a red arrow), a subtle environmental cue of their previous action (a cursor that was placed in the same location as their previous action), or no environmental cue ...
متن کاملDesigning and Evaluation of Reliability and Validity of Visual Cue-Induced Craving Assessment Task for Methamphetamine Smokers
A B S T R A C TIntroduction: Craving to methamphetamine is a significant health concern and exposure to methamphetamine cues in laboratory can induce craving. In this study, a task designing procedure for evaluating methamphetamine cue-induced craving in laboratory conditions is examined. Methods: First a series of visual cues which could induce craving was identified by 5 discussion sessions b...
متن کاملMeasurement of Cue-Induced Craving in Human Methamphetamine- Dependent Subjects New Methodological Hopes for Reliable Assessment of Treatment Efficacy
Methamphetamine (MA) is a highly addictive psychostimulant drug with crucial impacts on individuals on various levels. Exposure to methamphetamine-associated cues in laboratory can elicit measureable craving and autonomic reactivity in most individuals with methamphetamine dependence and the cue reactivity can model how craving would result in continued drug seeking behaviors and relapse in rea...
متن کاملEffect of Redundant Haptic Information on Task Performance during Visuo-Tactile Task Interruption and Recovery
Previous studies have revealed that interruption induces disruptive influences on the performance of cognitive tasks. While much research has focused on the use of multimodal channels to reduce the cost of interruption, few studies have utilized haptic information as more than an associative cue. In the present study, we utilized a multimodal task interruption scenario involving the simultaneou...
متن کاملDirect and Indirect Measures of Attention Indicate a Bias Toward Cues in Methamphetamine Users
Introduction:This study aims to investigate the attentional bias toward drug-related stimuli along with subjective craving after encountering such stimuli in methamphetamine users. Studies of cue reactivity have confirmed bias in attention and gaze to drug-related stimuli for most substances, but methamphetamine drugs are less studied by a direct measure such as eye tracking. Methods:Thirty ma...
