HAP-NAV: Revolutionizing Navigation for the Visually Impaired 

The Health Innovation Via Engineering (HIVE) Laboratory at the University of Galway is proud to introduce HAP-NAV, a groundbreaking haptic navigation device designed to transform the way individuals with vision impairments interact with their environment. This innovative technology represents a significant advancement in assistive devices, offering a new level of independence and safety for people with visual impairments.

HAP-NAV stands at the intersection of artificial intelligence, ultrasound ranging, and haptic feedback, creating a unique system that enables users to mentally map their surroundings in three dimensions. By wearing the HAP-NAV device, users receive real-time tactile feedback that guides them through their environment, alerting them to obstacles and helping them navigate with confidence.

The core of HAP-NAV’s technology lies in its sophisticated use of ultrasound ranging to detect objects and obstacles in the user’s immediate vicinity. This information is processed through advanced AI algorithms that interpret the spatial layout, translating it into intuitive haptic signals. These signals are then conveyed to the user through a wearable device, providing a tactile representation of the environment that allows for a detailed mental construction of their surroundings.

HAP-NAV is more than just a navigational aid; it’s a tool for enhancing spatial understanding and mobility. For individuals with vision impairments, navigating unfamiliar spaces can be challenging and sometimes hazardous. Traditional aids like canes and guide dogs offer valuable assistance, but they may not provide a comprehensive understanding of the environment. HAP-NAV fills this gap by offering a way to ‘see’ the world through touch, empowering users to move more freely and safely.

The development of HAP-NAV is a testament to the collaborative spirit of innovation at the University of Galway. Bringing together experts in engineering, artificial intelligence, and assistive technologies, the HIVE Lab has created a device that stands to make a real difference in the lives of people with visual impairments. The project underscores the university’s commitment to leveraging technology for social good, aligning with its mission to create solutions that improve quality of life.

s HAP-NAV continues to evolve, the team is focused on refining the technology, expanding its capabilities, and ensuring its accessibility to those who can benefit most. The ultimate goal is to bring HAP-NAV to the global market, providing a new level of support for the visually impaired community worldwide.
