The low vision industry is built around a user-first ethos: everyone working in the field wants to find solutions that will improve the lives of vulnerable people. Nonetheless, it remains competitive and poorly funded, so it can feel like the risks outweigh the rewards for entrepreneurs. Maël Fabien, co-founder and CEO of biped, spoke to us about balancing these conflicting demands and working with blind people to create a viable solution that is truly built for them.
Where did the idea for biped come from?
The idea for the company was actually born from a chance encounter. During my PhD at EPFL, I was out on a walk through Lausanne city centre and I came across a visually impaired person holding a cane and FaceTiming a friend – in the absence of other aids, the friend was trying to direct the caller to their destination. I chatted with them for a while and it got me thinking about whether I could build something better, maybe something AI-powered, which would allow a blind person to move around independently.
What aids are currently available for visually impaired people?
The most common solution you’ll find on the market is the standard white cane. It’s easy to produce and obtain, plus it gives users a fair bit of haptic feedback about the ground around them. Proficient cane users can tell whether they’re walking on concrete or grass and when they’re about to step out onto the kerb. Nevertheless, the cane only detects basic floor-level elements: it offers no protection for the user’s upper body and no assistance in terms of detailed directions – they need to know the route themselves or have something or someone else helping them.
Then, you have guide dogs: they’re one of the most advanced mobility aids on the market, but once again, they don’t have a built-in GPS. And above all, they’re incredibly expensive to train – it costs over CHF 50,000 to train one dog. This means that in the UK, for example, only around 200 new guide dogs are trained every year, even though there are over 5,000 people on the waiting list for one. So you see the maths doesn’t quite work.
How does biped’s technology complement or surpass these existing aids?
We’re not necessarily aiming to replace other aids; rather, we’re leveraging technology to complement cane use, as well as help those waiting for dogs. After all, we’re dealing with a community of users who, without aids, can lose a good degree of their autonomy. So, leveraging the principles of self-driving cars, which use cameras to navigate autonomously, we’ve developed a harness that works in a similar fashion. It includes three cameras that have a 170-degree field of view, a small computer with embedded AI and a speaker that provides the user with continuous audio feedback – this states the directions, as well as beeping or clicking if there’s a risk of collision. It’s basically like having someone on FaceTime to tell you about your surroundings, but you’re still operating independently.
