Stochastic Resonance Phenomenon Induced by Visual Noise Stimulus Using a Mixed-Reality Device
https://onlinelibrary.wiley.com/doi/abs/10.1002/tee.70007

This study explores the potential of inducing stochastic resonance through visual noise presented via a mixed reality (MR) device. Stochastic resonance refers to a phenomenon where weak noise improves perceptual sensitivity in biological systems. Traditional methods using magnetic stimulation or fixed pixel noise on monitors are limited in portability and flexibility.

Introduction

Visual Noise Stimulation

Lorem ipsum dolor sit amet, at mei dolore tritani repudiandae. In his nemore vim ad prima consetetur temporibus.

Shape Recognition Task Under Noise Conditions

Experiments showed that presenting optimal levels of noise during a shape discrimination task enhanced correct response rates in most participants (8 out of 11).

Individual Optimization of Noise Intensity

Optimal noise intensity varied among individuals. By adjusting the background luminance relative to perceptual thresholds (100%–200%), resonance effects were maximized.

Conclusion

The results suggest that visual noise presentation is a viable method to induce stochastic resonance. This technique could expand applications in rehabilitation, sensory support, and cognitive enhancement.
