Hello Everyone,
Last month, I went to the in-person talk about Glide by Glidance in London. Launching in winter 2025, it's a new mobility aid for people with sight loss, that could replace a white cane, or guide dog. This post is about my thoughts on the device.
What is Glidance?
Glidance is a team of engineers, researchers, designers and technologists who are currently developing Glide, the world’s first self-guided mobility aid. Glide will "blend cutting-edge navigational robotics and AI with an intuitive and user-friendly experience". It also has a community of advocates, partners, supporters, advisors, and people committed to advancing mobility for millions of people. The CEO Amos Miller is blind himself.
How does it work?
Glidance has an AI system which connects the Glide device and uses real-time data to give you the best routes, find places of interest, navigate obstacles and guide you through the best way to reach your destination. According to the website, you can use the device to:
- avoid obstacles
- Find lifts, doors, stairs and more
- Pre-map routes
- Spontaneously walk without a destination in mind
In terms of the physical design of the device itself. It has:
- Telescoping handle with comfortable grip, that's at a height of 22 inches (55.88 cm) when fully compacted.
- haptic feedback in the handle which tells you the direction you need to go
- Selection buttons and a programmable “quick access” button in the handle
- 8-inch replaceable terrain wheels with intelligent steering, power assist and dynamic brakes at the bottom
- Built in speaker, microphones and Bluetooth connection for audio feedback
- Stereo depth camera with 50-feet range, and near-range sensors for obstacle and cliff detection
- Rechargeable battery for 6+ Hour active use and smart standby for all-day charge
- Portable, collapsible and light (weights 6 pounds, 2.72 kg)
- Automatically steers and stops
- Path detection and guidance
- avoids obstacles with overhead and drop-off detection.
- Primary target detection and guidance (door, crosswalk, stairs, etc.)
- Voice input
- Companion app for setup and onboarding, device settings and Over-The-Air update
What's My Verdict?
During the Q and A session the team emphasised "glide is a tool", we as users need to know how to use the tool to make good decisions like when to cross the read safely. In other words, you still need to have good orientation and mobility skills to use the device. The reaction time of the device "is good", but also depends on your reaction time as a user. They mentioned "glide will see the stairs with the camera...inform you about the hand-rail (if there is one)" and then you roll the device, or pick it up and walk up the stairs yourself. The device will have LED lighting, which can be used at night when crossing roads. You should be able to use it to navigate familiar routes, or new routes. Plus, you can use it with either your left, or right-hand. For safety, the app could (in the future ) allow you to add your location that way. Other users suggested a button to alert emergency services via the device like the police, or your loved ones when in danger. It should be able to handle different weather conditions like snow and rain. It's a device the team believes could be used anywhere, like on the train, getting out of a car, or even on a plane. It has a "freestyle navigation" ability, things people need to be aware of such as roads, crossings and pre-mapped routes where you can train glide to take you where you need to go. The software on the device will be updated monthly, and the product is meant to last you at least 3 years, or more. They want people to be able to use it in "real-world scenarios".
Similar to a guide dog, when crossing a road, glide will help you safely get to the other side. The level of "haptic feedback" you get is similar to being led by a guide dog. According to the team "guide dog users take to using glide really well", compared to a cane user. As a cane user myself the test-run helped me understand why. When using a cane, I'm the one in control. I'm the one that knows where I need to go, and am using the feedback from my cane to make sure I know about gaps in the pavement, uneven pavements, steps, or obstacles I wouldn't usually see as I walk. In comparison with glide (and I'm assuming a guide dog), I am being led by the device itself, it's moving me forward, instructing me to turn right, left, or abruptly stop when it senses danger. I hold onto it and go where it's taking me. I move when it moves. I love the fact that the company have reached out to the sight loss community, given us a chance to try it, give feedback, ask questions and raise our concerns. This is something other companies could learn from. We know what we want, we know what we need, we have a voice, so listen and learn before creating your product or service.
Personally, that lack of control would take some getting used to. It'll take an adjustment period to solely trust and rely on the device to safely take me where I plan to go. In theory, it sounds like a brilliant device, that's a cross-between a cane and a guide dog. For people who don't want the responsibility of taking care of a guide dog, it could be a good alternative. However, I think it needs to be tested in real-life scenarios, such as crossing the road, navigating crowds, getting on the train platform etc. in a city like London these are real-life situations you would use the device, it's important to see how it fares in that environment. Also, different countries have different designs, some countries have narrow pathways that people walk through. Other countries have situations where the road and pavement become one. Can glide adapt to each countries existing system? Do you need to keep you cane on standby to go up and down the stairs? How big of a bag do I need to carry my glide and cane? Lastly, both the cane and guide dog are universally recognised as mobility aids. Would the general public understand what the glide device is?
IMAGE DESCRIPTION: photo of glide from the glidance website, on a pink and purple background. The device is shaped like a child's toy vacuum cleaner with a long white handle and two wheels on the right and left-hand slide at the bottom. The bottom part is red, with a black stripe above it and above that on white is the "glide" logo. The handle at the top has a black circle near it, which could be a camera.
Overall, I would rather wait to see what users think of the device once it's available in December 2025, instead of pre-ordering it right now. Yes, that does mean I would be missing out on the 30% discount pre-order price of $1049 (£834.53) and potentially pay $1499 (£1192.52). Plus you have to pay an additional $20 (£15.92) monthly fee for the software. To me, it's important to wait for reviews, learn from other peoples' experiences before investing in the product.
What would you do in my situation? Feel free to share your thoughts in the comments.
Thanks for reading!

‘I am being led by the device itself, it's moving me forward, instructing me to turn right, left, or abruptly stop when it senses danger. I hold onto it and go where it's taking me. I move when it moves. ‘
ReplyDeleteHi interesting blog but readers must know that the above quote is a little bit misleading. The fact is that you push the glide? It is not powered. It doesn’t lead you it guides you by avoiding obstacles but you have to provide the push power you are therefore in control of the glide.
I've also been following this company's progress and share many of your concerns. While their promises are ambitious, the prototypes I've seen haven't convinced me they can deliver even half of what they claim.
ReplyDeleteMy skepticism stems from several key areas. First, the prototypes appear extremely limited in scope. I haven't seen any evidence of real-world testing with actual users in diverse environments like crowded city streets, which you rightly point out as a crucial test. The promotional videos, featuring the CEO seemingly using the device around his neighborhood, seem heavily edited and staged. It's telling that he doesn't use the device at public events like conferences.
Beyond the lack of real-world testing, I have significant reservations about the device's practicality and durability:
Low-Light Performance: Will the cameras function adequately in dimly lit conditions? This is a critical safety concern.
Environmental Durability: The device seems unsuitable for challenging environments like beaches, hiking trails, or areas with snow, ice, or road salt. Rain and puddles also pose a significant risk, as it's unclear if the device can withstand any level of water exposure, let alone emersion from heavy rainstorms and puddles. The need for frequent wheel replacements seems likely depending on the environment of the user.
Weight and Maneuverability: Finding the right balance between a lightweight design and ease of use will be crucial. Too light, and it might be difficult to control, especially at higher speeds. Too heavy, and it could be tiring to push, particularly uphill. Navigating curbs and steps will also be cumbersome, requiring users to constantly stop and lift the device. Guide dog users often rely on their dogs for a bit of a pull in the handle, and for subtle directional cues; I'm not sure how this device will replicate that.
Travel Durability: The device's resilience during travel is a major concern. How will it fare when stowed under airplane seats or in overhead bins? The cameras and sensors seem particularly vulnerable to damage, possibly requiring a specialized carrying case.
Furthermore, the company's business practices raise serious questions:
Funding and Timeline: It appears they are leveraging user pre-orders to secure further funding. Given that they've already missed their initial July deadlines, I'm highly doubtful they'll meet their 2025 shipping target.
Unfair Refund Policy: Their refund policy is deeply concerning. Refusing refunds until after the device ships, and then a 30-day trial period, even if the device is significantly delayed, is not standard practice and feels predatory. It essentially traps user funds for an indeterminate amount of time.
Exorbitant Price: The device is incredibly expensive, especially considering the mandatory ongoing subscription fee. This effectively doubles the already high upfront cost over the product's lifetime. Compared to a simple cane, which is readily replaceable and requires no maintenance, this device represents a significant financial risk, especially given the fragility of its electronic components. A single fall or impact could render it useless, leaving the user without a mobility aid and out a substantial sum of money.
Small Company, Limited Support: Given that it is a small company, they won't have the support logistics for fast repairs and replacements.
I have a lot of frustration with the assistive technology industry. Too often, companies exploit vulnerable populations by playing on their desire for independence with products that overpromise and underdeliver. While I fully support the development of alternatives to canes and guide dogs, this device, in its current form and with this company's current practices, does not appear to be a viable solution. I won't be pre-ordering, and I'm deeply concerned for those who have already placed their trust and money in this venture. I fear many will be left disappointed, both by the delayed (or potentially nonexistent) delivery and by the device's likely failure to meet their needs and expectations.
Negativity reigns supreme in this web site post. I've ordered mine and having briefly tried it out at CSUN and ACB, I will give it more extensive use once it becomes available in September of 2025 and make my own decision one way or the other. I trust the individuals with this company Their constant communication with the blind community in building this Glide is very welcome and so instead of being very negative as Betas are now being tested, I'll wait until I have mine on a daily basis before I make a decision one way or the other.
DeleteThis post didn’t have anything positive to say about the product. I pre-ordered mine. I love the fact that they are using the blindness community to do the Q&A and get ideas for how to improve the prototype. If no one pre-orders, how is anyone going to give feedback after it is released? It would be like iPhone not being beta tested with VoiceOver. Instead of complaining, why don’t you join the Q&A Zoom calls and give your feedback. Or, send them an email. They are extremely responsive. Help them build a better product, instead of bitching and complaining. That gets us nowhere as a blindness community.
ReplyDeleteAbove anonymous commenters assume that this is my first time doing this circuit with companies, and that I haven't actually provided my feedback to this entity. Truth is, I've provided them lots of feedback, but I also have seen the feedback from other entities that have gone down this road as well. I've interviewed many such companies through my podcast, have purchased many thousands of dollars in products from companies looking to revolutionize O&M, and yet, I am not enough of a fanboy so as to not be able to see the limitations of the product. I don't need to try it to make comments on the pricing of a Glide vs. a cane. I don't need to order it to tell you, as the company has already stated, that there will be issues with water... The device can handle splashes, some water, but not enough for a demanding environment. I don't need to get the product to tell you that 8-in wheels won't do well on rough sidewalks and certainly on curbs. I don't need to get the product to tell you that their timelines for their own evaluation process has already slipped, nor that this company hasn't promised people who ordered a glide that they will get it in September, merely that they hope to start shipping at the end of 2025, which is actually quite different. It takes effort and time, after all, to scale such a venture.
DeleteAs for the very silly comparison to iPhones... Nobody put a bunch of money down on an iPhone, waited over a year to receive a product (if it is shipped in that timeline), was told they could not get refunded for their deposit until not only after they receive the product, but after they wait an additional 30 days... Sorry, but there is really no comparison here. This is more akin to a kickstarter project, one which is unproven and has no actual working prototype doing all the things they claim it will do, and if you know anything about those projects, you'll note that the vast majority go absolutely nowhere.
I do praise them for engaging with the community, I applaud them for attending conferences and building excitement through Zoom calls, but I'd argue that other entities have done the same, and it benefits them to do this, as they can go to investors and point to the number of preorders, point to the number of attendees on Zoom, etc., as a reason for why they should get funding. Again though, they are quite unproven, and paying $1K or more on a device with the price very likely to increase, and about that same amount over its lifetime in subscription costs, I'd say that it's important to go into this without blinders... The people who get this device are vulnerable, they very much seek greater independence, they will hang onto the words of this company as tightly as they hang onto anything as is evidenced by the above comments... It therefore goes to reason that they should get what they're paying for, rather than getting taken advantage of by a company simply looking to do what they have to do to survive in an uncompetitive industry.
ReplyDeleteI share everyone's concern about this device. Moreover, what happens if the glide encounters a stray dog or other animal? Can the device function under significant temperature variations?
