Maël Fabien
Harnessing self-driving technology to guide the visually impaired
Listen on your favorite platform:

Given the rapid progress made in this field in recent years, autonomous vehicles could soon become part of our daily lives, bringing with them all the consequences and questions they raise in terms of modern mobility.

This would benefit people with visual impairments who are unable to drive.

However, it wouldn't necessarily assist them in their pedestrian moves, which will always play a significant role in their daily lives.

Maël Fabien became aware of the lack of available solutions in this regard during a walk in town. He noticed a visually impaired person video calling a friend, who was guiding her through his voice based on the video she was sharing.

As a result, he took inspiration from the latest advances in autonomous vehicles to create a harness capable of continuously analyzing the pedestrian environment, and safely guiding its users in all their movements.

From there, Biped was born, a device that promises to improve the life of the 270 million visually impaired people worldwide, by providing them with a much more accurate and secure perception of their environment than traditional solutions.

In this surprising episode, you will learn about:

  • The daily life of a visually impaired person and its impact on mobility

  • How Biped was developed in close collaboration with its end users

  • Some key concepts of autonomous mobility and the sensors that constitute it

  • How Biped translates the user's 3D environment into audio cues for guidance

  • The potential applications of Biped beyond ophthalmology

An outlook on the future of mobility and what it might change for those with limited vision!
