There is a growing interest to understand the neurobiological mechanisms that drive positive associations of physical activity and fitness with measures cognitive performance. To better those mechanisms, several studies have employed eye-based (e.g., eye movement such as saccades, pupillary pupil dilation, vascular retinal vessel diameter) deemed be proxies for specific mechanisms. However, there currently no systematic review providing comprehensive overview these in field exercise-cognition science. Thus, this aimed address gap literature. identify eligible studies, we searched 5 electronic databases on October 23, 2022.

You Can’t Hide Behind Your Headset: User Profiling in Augmented and Virtual Reality

IEEE Access, Journal Year: 2023, Volume and Issue: 11, P. 9859 - 9875

Published: Jan. 1, 2023

Augmented and Virtual Reality (AR VR), collectively known as Extended (XR), are increasingly gaining traction thanks to their technical advancement the need for remote connections, recently accentuated by pandemic. Remote surgery, telerobotics, virtual offices only some examples of successes. As users interact with XR, they generate extensive behavioral data usually leveraged measuring human activity, which could be used profiling users' identities or personal information (e.g., gender). However, several factors affect efficiency profiling, such technology employed, action taken, mental workload, presence bias, sensors available. To date, no study has considered all these together in entirety, limiting current understanding XR profiling. In this work, we provide a comprehensive on user technologies (i.e., AR, VR). Specifically, employ machine learning head, controllers, eye data) identify infer individual attributes age, Toward end, propose general framework that can potentially any from scenarios.
