Sage Journals: Discover world-class research

Abstract

This research examines the selection of nonspeech sounds for use in a computer-based application and furthermore assesses the performance of users engaged in a simulated manufacturing task. An empirical study was conducted to evaluate the utility of spatially-enhanced (three-dimensional) auditory cues in the computer interface. The seventy-two participants in this experiment interacted with a simulated interface using one of two spatially-enhanced sound groups (pure and hybrid) as selected from previous studies. Participants used the mouse to interact with the interface simulation and received alert information in the form of auditory cues, textual cues, or both. Performance for the simulated interface was measured in terms of: skill acquisition (learning), perceived workload, task omissions, incorrect responses, and task response time. The results show that spatially-enhanced nonspeech auditory cues can reduce perceived workload and shorten response times.
