This application is designed to enhance human recognition ability by leveraging the phenomenon of stochastic resonance. By overlaying controlled visual noise stimuli on the smartphone screen, the app introduces a low level of random fluctuations that can amplify weak sensory signals. This effect, known as stochastic resonance, occurs when the presence of an optimal level of noise actually improves signal detection in nonlinear systems, such as the human sensory system.

In practice, the app displays specific patterns of visual noise (e.g., white, pink, or Gaussian noise) during tasks that involve object recognition or visual discrimination. This stimulation can help users better detect faint or ambiguous visual targets, potentially improving cognitive performance in low-visibility or high-distraction environments.

The app is non-invasive, non-consumable, and allows users to adjust the noise intensity and type according to their individual sensitivity and task demands. It is particularly useful for cognitive training, attention enhancement, and research in perceptual psychology or neuroscience.
