• Keywords: Temporal feedback, wait-time perception, task performance, interruptions, cognitive workload, user experience, countdown timers, elapsed time, system delays, HCI

Background and Problem

• Problem / challenge: While prior research has explored how temporal feedback affects wait-time perception, little is known about its impact on downstream task performance and overall user experience during system-imposed delays.
• Significance: Understanding the effects of temporal feedback can inform interface design to improve user experience and task engagement in latency-prone systems.
• Motivation and related work: Existing studies focus on time perception during waits or immediate post-delay judgments but overlook how temporal feedback influences task resumption and performance. Interruptions literature addresses resumption costs but rarely examines the role of temporal feedback during the wait itself.

Solution

• Proposed approach: A controlled experiment investigating the effects of three temporal feedback modes (No Time Display, Elapsed-Time, Remaining-Time) and three wait durations (10, 30, 60 seconds) on task performance, cognitive workload, affect, and perceived wait-time experience.
• Novelty:
  1. Examines downstream task performance after system-imposed delays with varying temporal feedback modes.
  2. Integrates psychophysical and cognitive workload principles to analyze subjective and objective outcomes.
  3. Provides empirical insights into how temporal feedback shapes user experience without affecting task performance.
  4. Offers actionable design guidelines for latency-prone digital systems.
• Procedure and key techniques:
  • Participants (N=425) completed a visual reasoning task based on the CLEVR dataset, split into two segments separated by a system-imposed wait.
  • Temporal feedback modes and wait durations were manipulated in a 3×3 between-subjects design.
  • Post-task surveys measured cognitive workload (NASA-TLX), emotional state (PAD model), perceived duration, and qualitative reflections on the wait experience.

Results

• Concrete findings:
  • Temporal feedback mode significantly influenced perceived duration, frustration, and pleasantness but did not affect post-wait task performance.
  • Remaining-Time feedback increased frustration and reduced pleasantness compared to Elapsed-Time feedback.
  • No Time Display made waits feel subjectively longer and heightened interpretive ambiguity.
  • Longer waits (60 seconds) were associated with lower temporal demand and more opportunities for mental recovery.
• Advantage over baselines:
  • Temporal feedback modes improved subjective clarity and reduced ambiguity compared to No Time Display but did not enhance task performance.
• Experiments / evaluation:
  • Task performance was measured as the percentage of correct answers in the second task segment.
  • Subjective measures included perceived duration, cognitive workload (NASA-TLX), and emotional state (PAD model).
  • Qualitative analysis identified seven themes, such as Restorative Pause and Affective Dysregulation, from participants’ reflections on the wait.
• Limitations and future work:
  • The study focused on short, determinate waits (10–60 seconds) and a repetitive visual reasoning task, limiting generalizability to more complex workflows or indeterminate delays.
  • Future work should explore richer graphical feedback, longer or unpredictable waits, and task types with higher cognitive demands.

Summary

This study investigated how temporal feedback modes (No Time Display, Elapsed-Time, Remaining-Time) and wait durations (10, 30, 60 seconds) affect user experience and task performance during system-imposed delays. Findings revealed that temporal feedback significantly influenced perceived duration, frustration, and pleasantness but did not impact post-wait task performance. Remaining-Time feedback heightened frustration, while Elapsed-Time feedback provided a calmer experience. These results suggest that temporal feedback primarily shapes the subjective experience of waiting rather than task outcomes, offering design insights for latency-prone systems. Future research should explore these effects in more complex and dynamic contexts.
