AURANAV

Para qué sirve

AURANAV is a wearable navigation system that uses proximity and motion sensors enhancing mobility and safety for blind and visually impaired individuals by detecting obstacles, particularly at head height, which are often missed by traditional canes.

Qué te inspiró

We discovered that blindness or visual weakness is the second most disabling disability, affecting 467 thousand people. Many of them face daily challenges navigating in new enxironments, especially when it comes to detecting abstacles above waist or at head level, which are not cover by the traditional tools like white canes. This is a widesrpead issue that needs to be addressed ta improve safety and independence for people with visual impairments.

Cómo funciona

These wearables are equipped with proximity (ultrasonic sensor) and motion sensors which are responsible for continuously scanning the space in front of and around the user’s upper body. The data is processed by a microcontroller, which triggers one of three vibration levels depending on the object's distance: soft for far, medium for closer, and strong for near. Each device works independently, allowing the user to sense the obstacle’s direction (left, right or front). AURANAV charges with USB-C charger and has an on/off button, design to be comfortable, lightweight and ergonomic, for long time use, made of polyurethane, nylon and velcro closures resisting sweat and water. The neck-worn device has two parts, the base and the top with the electronic components, these two parts are joined by a magnet so it doesnt fall, and the lenght of the strap is designed to fit into different complexions.

Proceso de diseño

Our initial concept was a single wristband with basic vibration feedback, but after doing validations we created a second prototype that included two wristbands and a neck-worn device equipped with proximity and motion sensors. Offering wider detection coverage and understanding of the user’s surroundings. At first, we used an infrared sensor for validations, which this changed to an ultrasonic sensor because of the size and the angle and range detection. We tested several types of vibration patterns to finally decide to include three distinct vibration levels and optimized the comfort and fit of the wearable components. Also, making several printed prototypes to defined the final form, size and materials, prioritizing the comfort, durability and costs. Today, AURANAV is in two prototypes, the functional and the aesthetic prototype.

Qué lo hace diferente

AURANAV stands out from existing products by specifically addressing a critical blind spot that are often undetected by canes. Unlike many existing assistive technologies that use audio feedback, AURANAV uses silent vibration patterns, allowing users to interpret distance intuitively without interrupting their hearing, which is a key sense for mobility. This multisensory, discreet, and hands-free system offers a more complete and user-friendly navigation experience.

Planes para el futuro

We aspirate to develope a fully functional prototype by advancing the technology, having the main goal to miniaturize the electronic components, so they can fit into the final wearable form. We are also seeking investment and funding opportunities to support the technical development, material sourcing, and manufacturing of the final prototype. Bringing AURANAV to market as an accessible and reliable mobility aid, having collaborations with rehabilitation centers and accessibility organizations to ensure it reaches the people who need it most.
