A team of computer scientists in Austria has developed InnoMake, an innovative shoe designed to help visually impaired individuals detect and avoid obstacles while walking. The project is a collaboration between Tec-Innovation, an Austrian tech company, and Graz University of Technology. Retailing for over $3,000, the smart shoe integrates advanced sensory technology to provide real-time feedback for safer navigation.
Each InnoMake shoe features a waterproof ultrasonic sensor positioned on the toe. These sensors can detect objects up to 13 feet (4 meters) away. When an obstacle is detected, the shoe sends vibrations or audible signals to alert the wearer, working similarly to parking sensors in modern vehicles. The system helps prevent collisions with common hazards like walls, vehicles, or stairs.
Co-founder Markus Raffer, who is visually impaired himself, praised the product’s effectiveness, noting that it has already become a significant aid in his daily life. His personal experience has influenced the shoe’s user-centered design and functionality.
The InnoMake system is versatile, offering a full shoe option or a retrofit sensor that can be attached to other footwear. Impressively, the sensors can also identify the type of obstacle and adjust alerts accordingly. This level of precision helps users understand their environment better in real time.
Looking forward, Tec-Innovation aims to enhance InnoMake by incorporating camera-based recognition and machine learning. These features would enable the system to create a virtual map of safe paths, akin to a “street view” from the user’s foot-level perspective, enhancing spatial awareness even further.
Experts like Friedrich Fraundorfer from TU Graz are optimistic. He explained that camera data is used to identify walkable paths and distinguish between various objects, increasing overall safety. InnoMake represents a meaningful advancement in assistive technology, offering greater independence and mobility for the blind community.
