Vision loss and visual impairment are major concerns in society, especially as the population ages. Researchers from The Hong Kong Polytechnic University (PolyU) and The University of Waterloo have collaborated to create a groundbreaking device utilizing Augmented Reality (AR) technology. This device aims to revolutionize navigation for visually impaired individuals, providing them with a newfound sense of independence and freedom.
The research project, known as “Augmented Reality Obstacle Detection” (ObstAR), is led by Prof. Allen Cheong from PolyU and Prof. Ben Thompson from the University of Waterloo. The goal of the project is to develop an AR-based navigation device that reduces visually impaired individuals’ reliance on traditional tools like canes or assistance from others. The device integrates advanced algorithms for obstacle avoidance navigation, object recognition, scene recognition, text recognition, and gesture recognition, ensuring safe navigation and heightened environmental awareness.
One key aspect of the research is identifying specific areas of interest (AOIs) such as traffic lights, zebra crossings, sharp turns, and large banners. This personalized guidance can greatly benefit users who frequently navigate the same routes, as the system offers customized support based on their familiarity with the environment. The innovative algorithm for image segmentation and information fusion, utilizing RGB and depth cameras, allows for real-time obstacle avoidance navigation and accurate recognition of obstacles.
The ObstAR device has been recognized for its excellence in assistive technology, receiving the prestigious “Gold Medal with Congratulations of the Jury” at the 49th Geneva Inventions Expo. Prof. Cheong believes that the advancements in AR technology provide an ideal platform to introduce this new form of assistive technology, showcasing the immense potential of technology in enhancing the quality of life for the visually impaired.
Prof. Cheong’s research interests focus on the psychophysical, behavioral, and clinical aspects of aging and low vision research. The ObstAR device has the potential to have a profound impact on visually impaired individuals, boosting their confidence in daily challenges and improving their overall well-being. The goal is not only to create an innovative product but also to bring about meaningful change and improvement in the lives of those living with vision loss.
The groundbreaking work done by researchers from PolyU and the University of Waterloo in developing the ObstAR device showcases the transformative power of technology in enhancing the lives of visually impaired individuals. By redefining independence and providing personalized navigation solutions, this innovative device opens up new possibilities for mobility freedom and social inclusion for the visually impaired.
