Proprioceptive accuracy in Immersive Virtual Reality: A developmental perspective

Area of Science:

• Developmental Psychology
• Neuroscience
• Human-Computer Interaction

Background:

• Proprioception, the sense of body position, is crucial for motor control.
• Visual input significantly influences proprioceptive development and accuracy.
• Understanding sensory integration is key to human development and interaction with technology.

Purpose of the Study:

• To investigate the developmental trajectory of visual-proprioceptive integration.
• To examine how Immersive Virtual Reality (IVR) environments affect proprioceptive accuracy across different age groups.
• To determine the influence of age, perception, and environment on proprioceptive development.

Main Methods:

• A self-turning task was administered to participants aged 4 to 43 years.
• Participants manually returned to a previous location in both IVR and real-world environments.
• Bayesian model comparison analysis was used to interpret results probabilistically.

Main Results:

• Children aged 4-8 years exhibited more proprioceptive errors than older individuals.
• Proprioceptive accuracy was consistently higher with visual input available.
• IVR environments significantly disrupted proprioceptive accuracy across all age groups.

Conclusions:

• Proprioceptive accuracy largely develops within the first eight years of life, with vision being a dominant factor.
• Visual-proprioceptive integration is susceptible to disruption by IVR technology.
• Findings highlight the importance of visual input for proprioceptive development and its potential vulnerability in virtual environments.
