Earlier quoted context omitted.

You have eyes + aren't active while finding food/avoiding predators in an environment with limited visibility & great sound conduction.

alright, what about nocturnal animals with huge sensitive eyes ? or why not evolve searchlights or even lasers ?

  > searchlights or even lasers
Think about the return on investment on these: how much energy to grow and power vs. the improved food gathering. Also: would this make the creatures easier to find by predators?

Galagos developed large eyes rather than sonar, true. I refer you to my other comment:

Please don't share sites like this. This is a common theme. People advertise "revolutionary products" for blind people, whithout actually explaining what kind of microactuators they use. I am 99% sure this is a fake non-invention that does not exist.

This site seems to share the common theme - a Braille tablet: http://blitab.com/videos/

Yeah, they are really common. While I was working in braille, my grandparents would send me a new "miracle invention" for blind people every week. Fucking disgusting. I don't even understand what these companies, and sometimes even seemingly non-profit organizations get out of this. But it also seems that it is a bug in the psyche of the tech industry that we share these stories and upvote them. We are obsessed with the idea that technology is changing the world and creating a utopia. The fact that we haven't managed to come up with a new micro-actuator for braille displays in 40 years doesn't bode very well for that theory [1].

To some extent, the current technology, which is called a piezoelectric display is like a lithium ion battery. Its not like we don't have other battery technologies, it is just that lithium is enough better than the others, that no other can take hold. The piezo displays are almost silent, last a LONG time (20 years), and take very little power. They are, however, slow and bulky and not practical for mobile applications. The mechanism is so large, you cannot create a multi-row display. (edit: they are also rediculously expensive!)

There have been multirow displays using solenoid actuators. These were hand made by grad students and weighed a ton. They used a huge amount of power and got jammed easilly. Other than that, there are pneumatic displays with huge potential, but are also bulky. There are static electric displays that have life expectancy issues, and a few other technologies, like using memory springs, that tend to have speed issues. Then there are a huge number of mechanical "conveyor belt displays" which are too noisy to use in a classroom or office.

But all of the displays you see being publisized are not the ones that I am talking about. Displays like the one you linked to are totally 100% FAKE!!!

Any reason for the blind to use this over earbuds paired with Siri, Alexa, or any other voice-based interface?

The made the mistake of asking this to my gf who is a teacher for visually impaired kids. Braille is reading, and listening to earbuds is not reading. We teach our sighted kids to read even though they could just all have audiobooks, just like we should teach children Braille even though they can still listen. Another good argument she made was it's about multiplexing. What if someone wanted to learn the time while l…

What kind of logic is "people need to do something more difficult because it's easier for people who aren't the same as me"?

Also, who's to say that people shouldn't be encouraged to use audiobooks rather then read text-based liturature? When listening to an audio book I can do many other things like study for an exam or program. I can't read a book via text and write software at the same time.

I don't think we should handicap people by making them feel like it's "better" to do something that's harder for them for some reason. Blind or not.

> Another good argument she made was it's about multiplexing. What if someone wanted to learn the time while listening to an engaging conversation, they wouldn't want to stop listening just to check the time.

Most people don't wear watches and it's usualy considered rude to pull out your phone mid-convorsation. I always wear a watch and so people just say "do you have the time"?

If you can't ask Siri you can just ask whoever you're talking to. Also, if you express you want to know the time and they say "I don't know" you can then just ask Siri and tell them. It works out nicely.

Any other examples?

I think we can all agree that my point is made, and it's easy to imagine sentient extraterrestrials without photoreceptors.

The original link was to the UK's RNIB, and they're pretty careful about avoiding hyped products.

https://audioboom.com/posts/5655817-the-first-braille-smartw...

They include interviews with blind people who've tried it.

They say that it's smaller, lighter, and cheaper because they use a new type of actuator that isn't "on a ceramic substrate".

The company plans to ship its first 150,000 devices by the end of the year for £300; the dot mini is an educational braille reader planned for sale for £650.

Here's a mashable link saying the product is shipping: http://mashable.com/2017/02/22/dot-smartwatch-retails/#c8Hyx...

I have been working for the past 7 years with a blind programmer. With a "tactile" watch, he can quickly know what time is it without minimal interaction with the hardware (open the lid, touch the watch, close the lid) and without disturbing the current course of action with other people. The same way you quickly check your watch. What I see as really good if it can hit the market at that price is that it will help p…

Wouldn't that be better served by a notch on the ring that rotates as time goes? An inner ring could do minutes and small/large bumps can help identify the time down to the closest 5 minute increment The machinery to translate scalar time into discrete bump movement is going to be complicate, fragile and costly, while rotating a ring instead of the single arms is feasible, has been done already and only need tactile…

What you've said can and does work for telling time, but from watching a few of their videos it looks like the watch part of this device is a secondary function. It connects to your phone and will display the caller's name or text messages like other smart watches, but in braille. I can't read braille, so don't know how effective that is with the limited space. It would be interesting to hear from a blind person what their current state of electronic connectedness is since this type of device is supposed to improve the parity between blind and non-blind individuals.

One of the cooler things mentioned in one of the videos (https://www.youtube.com/watch?v=zmpl81WmFSo) was that they developed their own magnetic actuators that are a 10th of the cost (if you believe the marketing) of existing ones. I haven't verified any of those claims, but if true does mean their braille tablet could be an affordable reality.

I somehow believe that the evolutionary pressure towards sight is so large (i.e. the benefit of sight is so great) that we're essentially guaranteed any sentient biological extraterrestrial will have it.

true, but consider other sighted animals but which have a different dominant sense: dogs (smell), moles (touch), platypus (electric-fields) even sight-dominant animals may have radically different vision to ours. Cats for example are more sensitive to motion than to static resolution How we obtain our data about the world is a huge influence over how we conceive of it. I wonder how different programming would be were…

A smartwatch for vision impaired, advertised a website without a lot of accessibility provisions (not to mention the scrolljacking and "are you sure you want to leave" onexit hooks). What a world we live in.

The onexit hook is surprisingly caused by the embedded Google form.

https://docs.google.com/forms/d/e/1FAIpQLScqZJxEjHf6j66cX8wy...

That message doesn't make any sense since I didn't even touch the form.

Their team doesn't look too diverse to me. Not a good culture fit for silicon valley.

It's a good thing they're based in South Korea then.

So it is not made in AMERICA? I think they underestimate the patriotism of blind people.
