Re: Blind Tech Guys Strap Device


If 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,

I’m definitely 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 kit.

Hello Dave,


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 moving in.


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 go.


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 doors.


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 needed to move their Head side to side back and forth
as well as up and down, to have the Beam cover the front, as the person
was walking.

Get to a set of Stairs, and the device would Beep a series of notes like
going up or down a scale.

Now, as far as I am concerned, if someone wants to purchase this type of
devise, go ahead.  If you think it will help you, by all means, go for it.

I can think of one aspect of using a Cane that might be  a problem using
this Strap Device.

I would be curious to try 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
let my thoughts frighten you away.

How would a person Trail, as they are walking along?

Let's say I have one of those situations where I am walking on a walking
area made of pavement, which is blended into the street. On the left,
there is a White line that helps Sighted folks from walking out into the
street.  And on the right is a Seam, or very narrow Crack where the
pavement meets the Cement of a Store Front parking area.

With a Cane I can feel the Texture differences between the pavement and
the Cement, or I might be able to detect the Seam or Crack.  Not sure
how those Sonar device would help in this situation.

And like with the Sonar Glasses of years past, does the operator need to
continuously twist their body from side to side to have the sonar beams
cover what's on the left and right?  That could be an interesting Boogie
Woogie move for someone to do while they are walking.

Personally, I have used a Cane for years, and I did have a guide Dog
for  several years.  I found the Dog was in general, better than using a
Cane, especially in deep Snow and packed Ice conditions.

But, the up keep and care of the Dog, and the reactions to the Dog
others would exhibit were down sides for me.  And when my Dog was
retired, I decided to return to using a Cane.

I have good cane skills so going back was not an issue, unless it Snowed
four or five inches over night, and I now had to wait for others to walk
on the walk ways to make a path I could follow with a Cane.

However, if anyone has this device, or had something like it in the
past, I would be curious to hear of your experiences with it.

Grumpy Dave
