Re: Sharing something very interesting
Re: Sharing something very interesting @5:I know, accessing a website to read graphs is not convenient, but I think the implementation is way good.. Those braille dots in edit box indicate the direction of the graph, for example, if it's braille dot 3 5, then you know that it's going upwards, if it's 2 6, then it's going downwards. And dot 3 6, or 1 4, would indecate that the graph is more or less flatter.I think they will probably package the entire thing in a convenient package once the development is done up to a satisfactory level so we can use the software offline. And it's very responcive too, something I appreciate so much.

Re: Sharing something very interesting
Re: Sharing something very interesting yeah. To be honest I don't know why, but no one has actually managed to beet Mathtrax. It's not the most flexible thing or even particularly generally applicable, but in terms of producing comprehensible graphs, it wins. If I recall correctly, size of the field and resolution/speed were all configurable as well.For some reason everyone who tries at this stuff fails. Also, having this in the browser isn't going to be useful to those of us who actually do real work with this stuff: you need to be able to connect it to the software/simulation you're running. That's also why I haven't touched Mathtrax since high school. Maybe one day I'll pick up my efforts at producing something again; it would have been nice if I could have gotten funding from the Holman prize but they went off and funded a bunch of inspirational stories for the most part, instead of those of us who wanted to produce lasting projects.

Re: Sharing something very interesting
Re: Sharing something very interesting Hi there,in my opinion, the best graphing program out there is still Mathtrax. It's made by a blind engineer working in Nasa, and while it's out for quite some time, it's really good.It has like seriously beautiful graphing sound. I don't know, wether its the sine wave or some other pattern, but it sounds great. There are tools in the program for some basic curve description like min, max, risings, descendings, shape etc.It is possible to scale the graph, and even use formula parameters, for which one can enter various values to see how they affect the graph.My small dream is to have something like this implemented in mathplotlib, and then tools like Tensorboard and Sage / Jupyter notebooks, so any visually displayed graph could be reviewed in Mathtrax way.Although I'm aware, that this would be most likely quite complicated, especially for graphs which are precomputed and then just displayed as images. There would need to be something like values semantics for each image, which would describe its graph with some predefined density, and could be then turned into desired sound and speech output.But anyway, it's an interesting idea.As for the project mentioned in the first post, well, I must say that I don't like the piano use much. Let me explain a bit.Say we have graphed a parabola, which we can imagine as a kind of U letter. It's not U of course in sense, that the legs are not vertical, just really steep, but for simplicity, we will take it as U here.Now, let's focus on the part, where in the U letter, a line is going straight down, and then curving, to form the bottom curvature.How do we describe the curving in sound?Well, if we decide to use 2 sounds, like D and C, we can map them to real points on the graph, yes, that's true. But when connected, those two points give us a line, and not a curve.This is a problem, as we're getting wrong informations about the function shape.So, to fix it, we introduce more points for graphing between the two selected. One gives us a V like shape, that's better, but not enough yet. Two points make somewhat clearer image, but still quite regular. Three points clear it further, four even more further etc.By using as many points as possible, we can draw the graph to a satisfying accuracy.And with a Mathtrax generated sound, this works quite nicely. A straight, descending line sounds the same when graphed using 10 points as well as 100 points with respective scales of course.However, if we use piano sounds for this, we need to use a whole note for each graphing point.Mathtrax uses, I don't want to be wrong now, 20 x 20 graphing field. I.e. From -10 to 10 horizontally, and -10 to 10 vertically.It can play a curve quite smoothly, as the generated sound is continuous.However, if we decide to use piano notes, just imagine it. 20 points in width, that means 20 notes with 1:1 resolution. Okay. But if we use 10:1 resolution instead to make a more precise graphing, that means we will need 200 notes.Isn't that... kind of too much for one simple curve?@3: which fields do you mean? I didn't see an option for graphing parabolas or square graph, but may be I've just missed them somehow.Best regardsRastislav URL: https://forum.audiogames.net/post/570677/#p570677 -- Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com https://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
Re: Sharing something very interesting
Re: Sharing something very interesting To be fair, I don't really understand how this works, especially the first link. But the graf calculator kind of makes sense, have I only known how to interpret the fields of the demo examples, like parables and such.For those who understand wth is going on in there, yeah sure, one step forward in accessibility!But for me, even with sighted help, I couldn't figure out what the hell was the first audible graf, if it really was a graf. Yeah, I get that there are some squares with something like dates, but above that, I understood nothing at all. What's it about, how and where do the squares connect, what it all means, etc.The graf calculator was more understandable, even if I DK what to put in those fields. The concept is pretty cool, though, it deserves at least that acknowledgement. So, can anyone explain what that is? For those that understand it, yeah, it's good, but I want to know what's going on as well...just because...I'm curious, what else can I say?

Re: Sharing something very interesting
Re: Sharing something very interesting Ooh neat! This combined with Desmos Graphing Calculator will be great.

Sharing something very interesting
Sharing something very interesting We all know what audio graphs are, but I've never seen such a nice implementation of this concept with such an easy to access interface. I hope that they really take it forward and get us a product wherin we can just feed in our graphs, and it will help us to learn graphs. This project can be accessed at:https://accessiblegraphs.org/view/index … ynthesizerThe project website is:https://www.accessiblegraphs.org/?lang=enI just stumbled across this thing while I was reading the NVAccess InProcess page of 7th september.
