During this year’s TechCrunch Disrupt NY hackathon, one innovative team created BackMap, a Raspberry Pi-powered haptic navigation system specifically designed to help visually impaired users navigate cities and indoor areas. This groundbreaking technology aims to provide a seamless and intuitive way for visually impaired individuals to move through various environments without relying on visual cues.
How BackMap Works
BackMap utilizes the Raspberry Pi to control motors connected to each strap of a backpack. These motors generate haptic feedback, guiding the user through vibrations. For instance, if the user needs to turn left, the left strap will vibrate, and similarly, the right strap will vibrate for a right turn. This method allows users to receive directional cues without needing to take their smartphone out of their bag, making navigation more convenient and safer.
The system cost roughly $40 to create a working prototype, which is remarkably affordable considering the potential impact it could have on the lives of visually impaired individuals. The team hopes that this prototype will eventually find its way into production, making it accessible to a broader audience.
Potential Applications and Benefits
BackMap is versatile and can be used both indoors and outdoors. This flexibility is crucial as it allows users to navigate a variety of settings, from busy city streets to complex indoor environments like shopping malls or office buildings. The system’s ability to function in different environments makes it a valuable tool for enhancing the independence and mobility of visually impaired individuals.
Check out the video below to learn more about the system, which can be used inside or outdoors and allows you to navigate an area without the need to take your smartphone out of your bag.
“I think that’s a pretty cool feature for people who are visually impaired, because if you walk into a store, you might not know how to navigate to certain places,” said Shashank Sharma, one of the team members behind BackMap. This statement highlights the practical benefits of the system in everyday scenarios, such as shopping or visiting new places.
Moreover, the affordability of the prototype suggests that with further development and potential mass production, BackMap could become a cost-effective solution for many visually impaired individuals. This could significantly enhance their quality of life by providing a reliable and user-friendly navigation aid.
In addition to its primary function, BackMap could also be integrated with other assistive technologies to offer a more comprehensive support system. For example, combining BackMap with voice-activated assistants or GPS applications could provide users with additional information about their surroundings, such as nearby landmarks or points of interest.
The development of BackMap is a testament to the potential of technology to address real-world challenges and improve lives. As the project progresses, it will be interesting to see how it evolves and what additional features might be incorporated to further assist visually impaired users.
