“Seeing-Eye Shoes” for the Blind: A Step Forward in Accessibility Technology
Austrian startup Tec-Innovation is revolutionizing mobility assistance for the blind with its innovative InnoMake shoe , a wearable device that uses ultrasound sensors to detect obstacles and alert users through haptic feedback and audible signals. Now, the company is taking this groundbreaking technology to the next level by integrating onboard cameras, enhancing the shoes’ capabilities and providing even greater independence for visually impaired individuals.
How the InnoMake Shoe Works
Each InnoMake shoe is equipped with a toe-mounted proximity sensing module that emits ultrasound pulses. These pulses bounce off objects in the user’s path, allowing the system to detect obstacles up to 4 meters (13 feet) ahead. When an obstacle is identified, the shoe delivers warnings via:
- Haptic Feedback : The shoe vibrates to notify the wearer.
- Audible Alerts : A Bluetooth-connected smartphone plays a sound to indicate potential hazards.
- Visual Signals : LEDs on the sensor module flash when an object is detected, offering additional cues for partially sighted users.
Developed in collaboration with Austria’s Graz University of Technology, the InnoMake shoe represents a significant advancement in assistive technology. However, Tec-Innovation isn’t stopping there.
Enhancements with Onboard Cameras
Scientists at Graz University of Technology are currently working on a camera-equipped version of the shoe’s removable sensor module. This upgrade introduces two key improvements:
- Complementary Sensing
By analyzing video footage from the integrated camera, deep-learning algorithms enhance the accuracy of obstacle detection. While the ultrasound system excels at identifying large objects, the camera ensures no smaller or less obvious hazards go unnoticed. - Obstacle Classification
When an obstacle is detected, the camera helps classify it, determining whether the user should:- Step over it (e.g., a rock or curb),
- Avoid stepping into it (e.g., a pothole), or
- Prevent collision with it (e.g., a wall or pole).
This classification allows for more precise guidance, ensuring users receive tailored alerts based on the specific nature of the hazard.
Creating Urban Obstacle Maps
Another exciting feature planned for the updated InnoMake shoes involves data sharing via the internet. As users navigate their environments, the sensor modules will collect information about obstacles encountered along the way. This crowd-sourced data can then be used to create detailed “obstacle maps” for various cities.
These maps would provide blind individuals with advance warnings about known hazards in specific areas, further improving safety and confidence during navigation. For example, if a particular street corner consistently features uneven pavement or a low-hanging branch, the map would alert users before they reach the location.
Availability and Cost
Currently, the standard InnoMake shoes without cameras are available for purchase directly from the company website. Priced at €3,200 (approximately US$3,840) per pair, these shoes represent a substantial investment but offer unparalleled value for those seeking enhanced mobility assistance.
There is no official release date yet for the camera-equipped version; however, ongoing research and development suggest that this advanced iteration is just around the corner.
The Future of Assistive Technology
The evolution of the InnoMake shoe exemplifies how cutting-edge technologies like ultrasound sensors, AI-driven cameras, and data-sharing platforms can transform everyday items into powerful tools for accessibility. By combining multiple sensory inputs and leveraging machine learning, Tec-Innovation is setting new standards for what wearable assistive devices can achieve.
For the millions of visually impaired individuals worldwide, innovations like the InnoMake shoe promise greater independence, safety, and freedom to explore their surroundings. Whether walking through bustling city streets or navigating quiet suburban neighborhoods, these “seeing-eye shoes” empower users to move confidently and securely—a testament to the power of technology to improve lives.
