There are many devices and tools developed to make life easier for visually impaired individuals. Most of these are designed for auditory processing, such as audio book readers, while some are focused on performing a single task, like systems that produce sound when a doorbell rings. However, these solutions generally require constant attention or manual activation by the user.

In reality, maintaining continuous focus is impossible in the flow of daily life, and these aids become even less effective, especially during sleep.

The goal is to facilitate the lives of visually impaired individuals by using a wearable sensor that does not require constant attention or wakefulness. This sensor will generate different vibration levels and combinations corresponding to predefined and identified sound frequencies, allowing users to perceive their surroundings more effectively.
