The reason that smartphones aren't used is because smartphones don't have the sensors required, and smartphones don't have the amount of cameras required to achieve the same level of precision from the front and sides of the body that the Strap device offers. It also wouldn't be great should you choose to use your phone while out and about. I do use my phone for something similar, using the vOICe app, and get soundscapes of what is in the image, which helps in obstacle avoidance and crossing streets and such. Before anyone asks, yes, you can cross streets with just a cane, and I do it all the time, but a cane won't help you stay in the crosswalk without veering, particularly on very wide roads, and it won't help you realize that there is a turn lane and an island that you must cross to first before crossing the rest of the road. A cane also doesn't see things as far, and when you walk quickly, as I do, every bit of extra reaction time is a great thing.
That's true. But in the longrun, I think a smart phone will be more useful. Especially if this device isn't popular and they stop making it.
I guess that would be good for all the people who have smart phones.
But it still wouldn’t be good for the rest of us. Pam.

I were wealthy, I might purchase this device just to play with it and provide
feedback to the developers. In the meantime, why can’t someone just develop
existing smart phone apps to do the same thing? Why can’t we just place our
smart phones in a wearable lanyard with the phone's camera facing away from our
bodies to accomplish the same things? Supersense and other similar apps could
accomplish the same things if these apps are developed a little more. If you
want this device, go out and purchase it. As for me, I’m not going to run out
and purchase this device just because it’s the latest thing that technology
developers think is going to be great. They are probably wrong.
I think there was a recently published article about robotic seeing eye
dogs. Honestly, I think such a device might be more useful than this device.
Again, I have never wanted a seeing eye dog. However, a robotic seeing Eye dog
might be useful.
Just my thoughts,
interested. New tech is always exciting. I wouldn’t pre-order, at least not
yet, but if it can do what they claim I may add it to my tech tool
This device is mounted to the chest for precisely the
reason you mention, the issue that people with glasses or with arm bands and
such end up moving about, thus making detecting obstacles more difficult. The
chest tends to be relatively proportional with the direction the body is
They also state that Strap will detect cracks in the
sidewalk, and assist users in travelling in a straight line. Is it trailing?
Sort of, but no. Guide dog users don't trail either, as you know, and use
different clues while traveling to get to where they wish to
I do have reservations, I don't think that this device, in
its first iteration, will be a great cane replacement, but I do think the
developers are worth supporting, and I do hope lots of people buy it to
provide the devs feedback, and to help this kind of a product move forward.
One concern I have is regarding detection of, for instance, doorways where the
door is closed, but this can be a challenge, to different degrees and in
different ways, with both a cane and a dog. The cane requires trailing which
may be a bit difficult if there is, for instance, lots of outdoor displays or
furniture, not to mention a bit noisy, and the dog may or may not want to
indicate a particular doorway, and may confuse windows with
Each mobility device has its pros and cons, but I do think
that a product like this is worth taking notice of, and at least trying and
providing meaningful feedback for.

Devices like this have been
made before. I recall one such device that
was built into a pair of
glasses. Think they were called Sonar
Glasses. The user

as well as up and
down, to have the Beam cover the front, as the person

something like this, but at first glance, I
can't see how it could do as
good of job as my Cane. But, again, don't

there is a White line that helps Sighted folks from

With a Cane I can feel the Texture differences between the
