A voice picking system using localized navigation speech and Head Tracking

Abstract

We propose a voice picking system that uses localized guide speech oriented towards the target object, and Head Tracking (HT), which maintains the localized speech position according to the user's head movement. We verified the usability improvements achieved by the proposed system. The task completion time was reduced by about 1.8 seconds (11.2%) compared to conventional diotic conditions. The post test questionnaire showed that the HT condition is preferred over conventional diotic systems by 1.92 on a 7-point scale. Thus, with the introduction of sound localization in voice picking systems, both the user satisfaction and task efficiency can be improved.
