Effect of Feedback on Users’ Immediate Emotions: Analysis of Facial Expressions during a Simulated Target Detection Task

摘要: Safety-critical systems (e.g., UAV systems) often incorporate warning modules that alert users regarding imminent hazards system failures). However, these are not perfect, and trigger false alarms, which can lead to negative emotions affect subsequent usage. Although various feedback mechanisms have been studied in the past counter possible effects of errors, effect such errors on users’ immediate task performance is clear. To investigate influence affective participants’ emotions, we designed a 2 (warning reliability: high/low) × (feedback: present/absent) between-group study where participants interacted with simulated identify neutralize enemy vehicles under time constraint. Task along facial expressions were analyzed. Results indicated giving decreased fear during whereas increased frustration for high reliability groups compared low groups. Finally, was found performance.
