This innovative device is designed as a wearable like normal spectacles to assist visually impaired individuals in navigating their surroundings safely and independently. Using a combination of ultrasonic sensors and auditory signals, the device helps users detect and avoid obstacles.
- Wearable Design: The device is integrated into a spectacle-like frame, making it easy and comfortable for daily wear.
- Ultrasonic Sensors: Positioned to detect obstacles in various directions—left, right, and front. These sensors provide spatial awareness by measuring the distance to objects in the user's path.
- Arduino UNO Microcontroller: Serves as the brain of the device, processing data from the ultrasonic sensors to determine the proximity of potential obstacles.
- Buzzer System: Once an obstacle is detected within a critical range, the Arduino triggers a soft sound alert through a buzzer fixed near the ear. This sound informs the user of the obstacle's presence and direction, allowing them to adjust their movement accordingly.
- Directional Alerts: The system is capable of alerting the user about obstacles from various directions, enhancing maneuverability and safety.
- Distance and Source Identification: It uniquely identifies both the source and the distance of the obstacles, providing nuanced feedback to the user.
- Ease of Use: The device is simple, requiring no special training, making it accessible to all visually impaired users without the need for extensive orientation.
- Increased Independence: Users can move more freely and confidently without reliance on a human guide or service animal.
- Safety: Reduces the risk of accidents by providing real-time alerts about nearby objects that could pose a hazard.
- Affordability and Accessibility: Designed to be cost-effective and easy to assemble with commonly available components, this device aims to be accessible to a broad audience.
The device has undergone rigorous testing to ensure reliability and effectiveness. Feedback from initial users indicates that the system significantly aids mobility and can handle a variety of everyday scenarios encountered by visually impaired individuals.
