Hi ZoltanJr
Yes, I have created a simple network, consisting of a couple of nodes and copied it into the clipboard. From there I pasted it into an editor and looked at the structured data. This should be a piece fo cake to parse and build 3D models from. I have also seen the Website where you can paste this code and it will render the nodes - good work by who ever did it!
I think navigating a large network could be a challenge, but it is the only approach I can think of that would make the user independent as far as building the network is concerned. By having a decent 3D printer on hand, new nodes can be printed quickly on demand, which should get round the issue of having a ready supply of nodes. Also, frequently used nodes can be printed ahead of time.
The trouble with audio readers is that they can’t handle drag and drop user interfaces and Braille screen readers are both very, very expensive and don’y have the resolution needed.
On previous tasks, I have used tactile resources and they worked well, hence the extension of the concept to UE4’s Blueprints.
Thanks for your ideas though - I am sure that there are lots of other things I have not thought about which I will find out as I progress this
