Description
With the recent surge in augmented reality (AR) applications, devices such as head-mounted displays (HMDs) and headphones are increasingly used as multimodal interfaces that combine visual and auditory information to create immersive experiences. However, to date, studies have focused on evaluating the impact of head-worn devices (HWDs) on head-related transfer functions considering either different headphones or HMDs without considering configurations where two such devices are used simultaneously, as sometimes can be in AR. This study aims at bridging this gap and presents a perceptually-based numerical evaluation of the impact of HWD configurations on HRTFs. HRTFs were measured on a KEMAR mannequin wearing four configurations of HWDs including two pairs of headphones (MushRoom and AKG K1000) measured with and without an HMD (Meta Quest 3). Results are presented in terms of interaural cues, estimates of perceived localisation-, and colouration-induced error metrics.
