Abstract

A tool to study the apparent trajectories evoked by sounds (auditory trajectories) is presented. This tool is built with the aim of easing the task of the experimenters (building and analyzing interventions) and the task of the participants (reporting their opinions). By using infrared tracked controllers in a Virtual Reality environment, participants can freely describe the three-dimensional path evoked by a stimulus. The implemented tool also assists participants in recording trajectories by providing additional visual cues and feedback on the recorded data. A mock-up study is presented to demonstrate the benefits of the proposed system. Results from this study show that participants are able to accurately report elicited trajectories. While the implemented tool has limitations, such as the number of available blocks (only practice and main blocks), it could cover the needs of several laboratories. The tool is a valuable resource for researchers seeking to explore the perception and processing of auditory stimuli.
