You can’t hide behind your headset: User profiling in augmented and virtual reality

摘要: Augmented and Virtual Reality (AR and VR), collectively known as Extended Reality (XR), are increasingly gaining traction thanks to their technical advancement and the need for remote connections, recently accentuated by the pandemic. Remote surgery, telerobotics, and virtual offices are only some examples of their successes. As users interact with XR, they generate extensive behavioral data usually leveraged for measuring human activity, which could be used for profiling users’ identities or personal information (e.g., gender). However, several factors affect the efficiency of profiling, such as the technology employed, the action taken, the mental workload, the presence of bias, and the sensors available. To date, no study has considered all of these factors together and in their entirety, limiting the current understanding of XR profiling. In this work, we provide a comprehensive study on user profiling in virtual …
