![]() By affixing cameras to appropriate items such as glasses, soft caps, or goggles, head-mounted eye-trackers can capture gaze at real-world 3D objects and scenes (versus gaze during conventional screen-based eye-tracking tasks). ![]() Over the past two decades, the development of lightweight head-mounted eye-trackers has expanded the environments in which eye-tracking can be used. Eye-tracking provides a quantifiable metric of visual attention, providing information about what the participant is seeing and focusing on. What is your dog really looking at on a walk? What are young infants attending to when they interact with a parent? While it is impossible to ask nonverbal individuals what they are or are not attending to, we can gather other metrics of attention and perception in order to answer questions about the cognitive processes underlying their behavior. Additionally, eye-tracking revealed more fine-grained time course information and individual differences in looking patterns. ![]() We found that while completing a simple forced-choice treat finding task, dogs look primarily to the treat, and we demonstrated the accuracy of this method using alternative gaze-tracking methods. This new method, adapted from systems that are widely used in humans, allows for eye-tracking during more naturalistic behaviors, namely walking around and interacting with real-world stimuli, as well as reduced training time as compared to traditional stationary eye-tracking methods. We present a novel method for real-world eye-tracking in dogs, using a simple head-mounted mobile apparatus mounted onto goggles designed for dogs. In dogs, real-world eye-tracking has the potential to inform our understanding of cross-species cognitive abilities as well as working dog training however, a robust and easily deployed head-mounted eye-tracking method for dogs has not previously been developed and tested. Real-world eye-tracking, or head-mounted eye-tracking, allows participants to freely move through their environment, providing more naturalistic results about visual attention while interacting with objects and agents. In their daily lives, dogs must navigate a human-built visual world, yet comparatively little is known about what dogs visually attend to as they move through their environment. Humans rely on dogs for countless tasks, ranging from companionship to highly specialized detection work.
