The WeWalk Smart Cane 2 could be one of AI's few good use cases at CES 2025

WeWalk introduced a new version of its smart cane for people with visual impairments at CES 2025, bringing a redesign that addresses many of the first model’s shortcomings and adds AI features and more advanced sensors from TDK. It’s positioned as an alternative to the traditional foldable white cane. Co-founder Kursat Ceylan, who has been blind since birth, says Smart Cane 2 can make mobility easier and safer, offering features like turn-by-turn navigation and obstacle detection, along with a ChatGPT-powered voice assistant that puts on-demand information in users’ hands without the need for them to also juggle a smartphone.

The WeWalk Smart Cane 2 has a slimmer handle than its predecessor, which should make for a more comfortable grip, and the company says it’s now about as lightweight as a standard white cane. It has tactile buttons to be more user-friendly, doing away with the touchpad of the previous model that some people found to be difficult to use. Ceylan says it can be used in different weather conditions, not just when it’s warm and dry (WeWalk describes the new cane as “rainwater-resistant”). The battery life is about 20 hours.

“You can fold and unfold it when you need it. There’s a speaker, a microphone, obstacle detection technology and a flashlight to make visually impaired people more visible at night. And also it has motion sensors in itself to provide a more accurate navigation experience,” Ceylan explained.

Under the hood, the WeWalk Smart Cane 2 has an ultrasonic time-of-flight sensor, an inertial measurement unit with six-axis motion tracking, a pulse density modulated microphone and a barometric pressure sensor from electronics company TDK. When it detects something ahead, it alerts the user with both haptic and audio feedback, according to Ceylan.

He demonstrated this in the very cramped, noisy environment of the Las Vegas Convention Center, and I was able to hear over the crowd when the cane told him he was approaching an obstacle — in this case, a carpeted step marked with yellow and black tape that I saw multiple CES attendees stumble over during our conversation. It also can connect to headphones via Bluetooth.

Paired with your smartphone, it can give navigation instructions and information about your surroundings, as well as public transportation options. “You can hear the names of stores and restaurants you are passing by,” he says. In Starbucks, where he isn’t able to read the menu, he says he might ask the assistant if they sell chocolate croissants.

“You don’t need to hold your smartphone anymore while you are going somewhere,” Ceylan said. “You can put it into your pocket and then you can get all the information through your WeWalk smart cane.” There is a smartphone interface for those who want to use it, though, which he held up through the demo so I could see what was going on on the other end. Unlike the vast majority of products I’ve encountered at CES this year that seem to include AI or ChatGPT for no real reason other than the fact that they can, this actually felt like a situation where it makes sense and could even be pretty beneficial.

Since it’s brand new, we don’t yet know how all of this will translate to real-world use. Pre-orders are now open for the WeWalk Smart Cane 2, and the first wave is expected to start shipping before the end of this month. There are two price models: $850 for the smart cane plus a subscription for the voice assistant that costs $4.99 per month, or $1150 altogether with no additional subscription fee for full use of the AI. WeWalk Smart Cane 2 is available internationally.

The London-based startup also has a partnership with the Canadian National Institute for the Blind (CNIB) that kicks off in February, when the organization will start using the WeWalk Smart Cane 2 for its cane training program. The goal is to gather meaningful data for instructors so they can really understand how people are using mobility canes (AI-enabled or otherwise), and help them get the most out of the tools. That, Ceylan says, “is so important, because the better you get around, the better you engage in life.”
