Current pass-through augmented reality systems can significantly impair user comfort, spatial orientation, and task performance, leading to a subjective experience akin to intoxication. This human factors research insight is drawn from a 2025 study published in Frontiers in Virtual Reality. Using Mixed-methods study with 20 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must prioritize reducing the perceptual lag and visual distortion inherent in PT-AR to ensure users can safely and effectively interact with their physical environment.
Pass-Through AR Disorients Users, Mimicking Intoxication
Current pass-through augmented reality systems can significantly impair user comfort, spatial orientation, and task performance, leading to a subjective experience akin to intoxication.
Frontiers in Virtual Reality · 2025
Key Findings
- 01Both low-end and high-end PT-AR systems negatively impacted user comfort and orientation.
- 02Participants reported symptoms similar to intoxication, including loss of coordination and difficulty concentrating.
- 03Task performance in real-world domains was hindered by PT-AR usage.
Application
Design takeaway
Designers must prioritize reducing the perceptual lag and visual distortion inherent in PT-AR to ensure users can safely and effectively interact with their physical environment.
How to apply
When designing or evaluating PT-AR interfaces, conduct user testing that specifically measures spatial awareness, balance, and performance on physical tasks, using validated questionnaires for simulator sickness and task load.
Project actions
- 01When testing AR, consider how it affects a user's physical interaction with their environment, not just their visual experience.
- 02Use established questionnaires like the SSQ and NASA-TLX to quantify user discomfort and workload.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Employs a mixed-methods approach for comprehensive data collection.
- +Evaluates PT-AR in the context of fundamental real-world tasks.
Limitations
The sample size is relatively small, and the study might not represent all user demographics or types of PT-AR devices.
Reliability & validity
The use of standardized questionnaires (NASA-TLX, SSQ) contributes to reliability. The mixed-methods approach, including interviews and observations, enhances the validity by providing qualitative depth to quantitative findings.
Think critically
Given the negative findings, what design interventions could be implemented to mitigate the disorientation and improve the user experience of pass-through AR systems?
Design Principles
"Minimize perceptual discrepancies between the real and virtual world in augmented reality systems to maintain user orientation and comfort."
As pass-through AR becomes more prevalent in consumer devices, understanding its impact on human perception and physical interaction is crucial. Designers must address these disorientation effects to ensure user safety and effective integration into daily activities.
What This Means for Your Design
Using AR where the real world is shown on a screen (pass-through AR) can make people feel dizzy and clumsy, like they've had too much to drink, and it makes it harder to do normal things like walk or handle objects.

Paragraph starter
Research indicates that current pass-through augmented reality (PT-AR) systems can induce significant disorientation and discomfort, leading to performance decrements in real-world tasks and subjective experiences akin to intoxication. This suggests a critical need to address the perceptual and cognitive load imposed by PT-AR to ensure user safety and effective integration into daily life.
