Startup. Device for persons with visual disabilities. How to implement?

Welcome.
Going to start a startup.
The idea the following.
Many individuals with visual disabilities who were totally blind, must be accompanied. Not necessarily those who are unable to navigate independently. But for example, lawyers, lawyers. Which is visited daily by different organizations and courts.
For these people, I came up with the device.
There is a device. Works on the principle of client-server applications.
The design of the device is semi-oval in shape, fits over the head.
In the embedded device:
4 cameras located at 4 sides of the world - South North West East;
Microphone;
Dynamics.
Device via the network connected to the server.
There is a client program that connects to the same server. The program is available for Windows, IOS, Android.
In the program we get:
The image with the 4 cameras with the option to expand the image from each camera separately;
The sound from the microphone;
The ability to capture sound from the microphone for transmission to the speaker device.
The point is that the blind will thus be able to accompany remotely.
Technical implementation:
Thinking about using Arduino or Raspberry Pi. Rather, I think of the Raspberry Pi, as a lot is required out of the box.
The only question is how to implement the design of the device. Combine all ingredients in one.
Ask experienced startups and programmers advice on how to implement, who to hire enough juna or need someone to seriously how much to invest.
Thanks in advance!

located on 4 cardinal directions - North South East West

This is an important clarification, Yes. You never know, someone decides that you're talking about the South-West, North-East, North-West and South-East.

Device via the network connected to the server.

By what means?

P. S. What prevents you to use your smartphone and any app for video call?
Well, to starpot only 4 cameras and a multiplexer (or how it there?) to ffmpeg packing no pictures from 4 cameras in one and connected the camera to the smartphone. And then luoi app for videochat not to invest in server infrastructure. - Morgan.Kilback commented on April 4th 20 at 13:07

IMHO, without automation, this design is not very useful.

You can read more about automation? What do you mean? - Felipe.Ziemann commented on April 4th 20 at 13:09
@Felipe.Ziemann, I meant that the device must be able to do something itself, such as Orcam, it is able to recognize faces (after training), items, ... - esther_Veum27 commented on April 4th 20 at 13:12
Nonsense. Such bulk.
Need a device that accompanies the saw around, and could tell where to go. Not accompany in the real world. And that's all, nothing more. - Felipe.Ziemann commented on April 4th 20 at 13:15

Swipe to the beginning of the experiment remotely to lead the blind with only one smartphone on the chest (the camera shows what lies ahead) and headphones. Via Skype, FaceTime or Duo or whatever with a video call. Only really remotely to Manager was sitting somewhere far.
Already. There is such a program, Be my eyes. Call, show camera, you describe real people on a video call, there.
But the downside is that the camera alone, and look only forward! - Felipe.Ziemann commented on April 4th 20 at 13:11
@Felipe.Ziemann, they focus on microzide to help to read what the label says or what color shirt. Not for long navigation.
Try as usability. - Morgan.Kilback commented on April 4th 20 at 13:14
another questionable point responsibility. Made blind the poor guy under the car at the intersection, and oops! tihonechko off, erase the app? - Morgan.Kilback commented on April 4th 20 at 13:17

But what with a delay and possible loss of signal and crash the software? And in General transmission of video from up to four cameras over the cellular network I think even with 4g is so-so, if at all, in the subway, subways, large buildings in General can lose contact
This thing is not for fun, people may be crippled, such a device should be reliable - niko47 commented on April 4th 20 at 13:13
Do you know about other reliable, high speed communication and data transfer? - Felipe.Ziemann commented on April 4th 20 at 13:16
@Felipe.Ziemann, Only 5g but go and wait for another 2 years at least, and that his coverage is worse than 4g - niko47 commented on April 4th 20 at 13:19
@niko47, no One is forcing you to use 4G. There are other ways.
While Yes, no one is immune in the loss of communication. Because I'm looking for other ways to send data more reliable. - Felipe.Ziemann commented on April 4th 20 at 13:22
@Felipe.Ziemann, What methods in addition to 4g ? - niko47 commented on April 4th 20 at 13:25
@Felipe.Ziemann, cable. There is no more reliable method of transmission. And then until that time until it is cut, or where it is not interrupted. You can not guarantee the quality of the connection, because you have your networks, and if you can't guarantee the quality of the connection in such a device means that you can't guarantee the safety of its use. - augusta.Rempel commented on April 4th 20 at 13:28
Do you know about other reliable, high speed communication and data transfer?

@Felipe.Ziemannknow: verbal communication, being close. - Morgan.Kilback commented on April 4th 20 at 13:31

While you are thinking to choose or Arduino or raspbery, the other a similar idea is already implemented and running.

Little difference what you select, take raspberry for prototype - will be faster.
But if you don't have the right skills and want to hire someone to do it, what and how to choose will decide the kind of person you will find.
To hire need the money enough - if it is enough for the señora señora, if in June - that June. Of course the result will be different, but this should be taken into account in your strategy of product creation and market entry.

PS. post sounds so don't want to do a startup and to create the device and a few apps.
