Navigation system for visual impaired persons based on satellital location.

Area of Science:

• Assistive technology
• Human-computer interaction
• Navigation systems

Background:

• Visually impaired individuals face significant challenges navigating urban environments independently.
• Existing navigation aids often lack the necessary detail or safety considerations for this user group.

Purpose of the Study:

• To develop and evaluate a GPS-based navigation system tailored for the visually impaired.
• To enhance urban mobility and safety for individuals with visual impairments through accessible technology.

Main Methods:

• Development of a GPS navigation system integrated with a Bluetooth hands-free device.
• Implementation of spoken command and direction functionalities.
• Route calculation prioritizing shortest and safest paths, including user-defined waypoints.

Main Results:

• The system provides spoken directions, enabling users to navigate urban environments with reduced reliance on external assistance.
• Route optimization considers not only distance but also safety, guiding users along convenient and less risky paths.
• Personalization through user-defined waypoints allows for customized travel plans.

Conclusions:

• The developed system offers a promising solution for improving the independent mobility of visually impaired persons in cities.
• Integration of GPS, spoken commands, and safety-focused route planning significantly enhances accessibility and user confidence.
• Personalization features further empower users to tailor navigation to their specific needs and preferences.
