Augmented reality (AR) technologies provide a shared platform for users to collaborate in a physical context involving both real and virtual content. To enhance the quality of interaction between AR users, researchers have proposed augmenting users’ interpersonal space with embodied cues such as their gaze direction. While beneficial in achieving improved interpersonal spatial communication, suchshared gaze environmentssuffer from multiple types of errors related to eye tracking and networking, that can reduce objective performance and subjective experience. In this paper, we present a human-subjects study to understand the impact ofaccuracy,precision,latency, anddropoutbased errors on users’ performance when using shared gaze cues to identify a target among a crowd of people. We simulated varying amounts of errors and the target distances and measured participants’ objective performance through their response time and error rate, and their subjective experience and cognitive load through questionnaires. We found significant differences suggesting that the simulated error levels had stronger effects on participants’ performance than target distance with accuracy and latency having a high impact on participants’ error rate. We also observed that participants assessed their own performance as lower than it objectively was. We discuss implications for practical shared gaze applications and we present a multi-user prototype system.
