Douglas Youvan 2015-12-11T15:55:30Z https://community.wolfram.com/groups/-/m/t/3057413 Hello, I'm using screen reading software packages such as JAWS For Windows or NVDA. For that reason, I have to do everything via my PC keyboard, without using the mouse. This means that I can only read text, not graphics, and that graphics are only accessible to me if they have a meaningful "alt" tag attached to them. Even though Wolfram Alpha's accessibility has improved over the past couple of years and I can use it to some extent, I think Wolfram notebooks must either be totally inaccessible for people who use a screen reader or I have no idea how I'm supposed to work with them when I can't use the mouse and when I can't read graphics. I have set up a basic account on Wolfram Cloud. I want to evaluate the entire contents of the file downloaded from a particular webpage (I can post the link later if someone's interested). It's a file with an ".m" extension. This means that when I open a new notebook, I'm supposed to copy the contents of the whole file into my new notebook and then choose "Evaluate all cells". I logged into my Wolfram Cloud account and I chose the button labeled "New computational notebook". I thought I was supposed to reach an edit field where I would paste the contents of the "main.m" file. But I did not find any such thing on the webpage. And if it's something other than a conventional edit field of the kind that I would fill in on a web form, then I don't know where I'm supposed to paste the contents of the ".m" file. I had a very long conversation with someone from the Wolfram support. The support person told me that they could only suggest me to read the Wolfram tutorial webpage called "Keyboard shortcut listing". But on that webpage, I'm unable to find anything that would help me to reach the field I'm looking for. And if I'm supposed to paste the text into something other than an edit field, then I have no idea what that would be. My question is simple: Is there anyone here who might be able to describe to me what I should be trying to find, avoiding phrases like "click the red button" or "click the blue icon" or similar? Those won't help me. I'm currently absolutely stuck. Thank you in advance. - Petr Petr Pařízek 2023-10-28T22:26:55Z https://community.wolfram.com/groups/-/m/t/3021201 More than year I am trying to resolve the following issue. My laptop has screen resolution 1920*1080 and I use Windows with setting 125% display scale in all applications. Wolfram Mathematica 12 works perfectly with option "screen resolution compatibility" and all the elements of interface are fine. However, it it almost impossible to use WM 13 because the application window and all elements of interface are huge. It seems that WM picks up 125% scaling from the global display settings in Windows. What should I do to keep WM using 100% scale in order to make the interface elements normal sized instead of huge? Artem Alexandrov 2023-09-25T17:09:52Z https://community.wolfram.com/groups/-/m/t/2103748 My 14-year-old son is medically complex, including being a quadriplegic. He currently uses software (Grid 3) to communicate ideas and an eye tracker (Tobii) with software that allows him to "type" using his eyes. I am looking for tools that will allow him to work out a math problem through its various steps (since he cannot hold a pencil and write on paper to show his work), and I thought Mathematica might be a tool that could help. Has anybody successfully used Mathematica using mouse movements alone and not typing anything on the keyboard? Thanks.

Steve Jacobs 2023-06-04T20:09:55Z https://community.wolfram.com/groups/-/m/t/2926319 Since this community encourages discussions, I post this in hopes of furthering the occasional interest shown in color accessibility. There were two WSS22 projects on it [[(1)](https://community.wolfram.com/groups/-/m/t/2581021), [(2)](https://community.wolfram.com/groups/-/m/t/2580694)], and there's [old 2017 post](https://community.wolfram.com/groups/-/m/t/1278303) that contains code for analyzing color accessibility that unfortunately relies on internal data that is no longer present in Mathematica. Some time ago I had a color-blind student, and it made me think about producing color-accessible notebooks for class. Somewhere I found the Okabe-Ito color scheme among other things. I copy-pasted the table below from some web site, long-forgotten I'm sorry to say. In any case, from time to time, such at the beginning of the COVID pandemic, I'd look further into color accessibility. I usually ended somewhat frustrated. There are a number of tools for simulating and measuring color accessibility. Unfortunately they tend to disagree. One is warned how difficult it is and of mistakes commonly made. Web sites tend not to be dated or have a log of when they are updated. Almost everyone says, in effect, "I know what I'm doing. Others might, or might not; so just believe me." But which one do you choose. So I find it difficult to find authoritative and reliable information. I hope it's out there, and I hope someone knows it. I'm sure it's simple once you have a trustworthy source. I don't know what I'm doing really. I'm sort of a weekend hobbyist. I'm sure someone with background in design and color accessibility could do a much better job much more quickly. I put together a color scheme for the items in the Appearance panel of the Preferences dialog. It's easy to load. It's easy to reset (there's a reset button in the Preferences dialog). Or you could save your current preferences and use them to reset. See below for more. I based the colors on the Okabe-Ito palette: $okabeItoData = Internal`PartitionRagged[#, {3, 3, 1, 4}] & /@ Partition[ {"R,G,B (0-255)", , , "R,G,B (0-1)", , , "Hex", "C,M,Y,K (%)", , , , 0, 0, 0, 0, 0, 0 , "#000000", 0, 0, 0, 100, 230, 159, 0, 0.902, 0.624, 0, "#E69F00" , 0, 50, 100, 0, 86, 180, 233, 0.337, 0.706, 0.914, "#56B4E9", 80, 0, 0, 0, 0, 158, 115, 0, 0.620, 0.451 , "#009E73", 97, 0, 75, 0, 240, 228, 66, 0.941, 0.894, 0.259, "#F0E442", 10, 5, 90, 0, 0, 114, 178, 0, 0.447, 0.698, "#0072B2" , 100, 50, 0, 0, 213, 94, 0, 0.835, 0.369, 0, "#D55E00", 0, 80, 100, 0, 204, 121, 167, 0.8, 0.475, 0.655, "#CC79A7", 10, 70, 0, 0}, 11]; $okabeItoColors = RGBColor @@@ $okabeItoData[[2 ;;, 2]]; (* Drop Black *) $okabeItoColorsDiverging = $okabeItoColors[[{1, 4, 6, 3, 5, 2, 7, 8}]] {RGBColor[0, 0, 0], RGBColor[0, 0.62`, 0.451`], RGBColor[0, 0.447`, 0.698`], RGBColor[0.337`, 0.706`, 0.914`], RGBColor[0.941`, 0.894`, 0.259`], RGBColor[0.902`, 0.624`, 0], RGBColor[0.835`, 0.369`, 0], RGBColor[0.8`, 0.475`, 0.655`]} I tweaked some of them as I built the color scheme. I used [Color Oracle](https://colororacle.org) to evaluate a scheme under the different types of colorblindness. As I said above, I don't know how reliable this tool is, but it is semi-easy to use. At some point, my sensibilities get burned out and I think any difference in color is a good difference. Later I'll wonder, why did I think that would be acceptable. There are lots of combinations that could be checked, and I don't have a good plan for systematically evaluating a change. I'm sharing here in case someone wants to pick up the ball and run with it. I don't think I can get a good result by myself. Deuteranopia (a form of red-green) colorblindness is the most common. So one should avoid red and green meaning different things (see the default debugger highlighting for the worst possible example). Red is used extensively, since it is a traditional warning signal; however, it is not a particularly good color-accessible one. `Magenta` seems better to me, but I don't know how it appears to a colorblind person used to seeing red warnings and dealing with the world 24/7, year-in and year-out, in their normal way. I substituted the red-brown Okabe-Ito color for the red in many of the Wolfram-Language preferences. Because I'm not red-green colorblind and that seemed a natural choice to. But it might not seem a good choice to a colorblind person. In one case, `"SyntaxErrorStyle"`, I used magenta, just to see and to show it. I rather liked the magenta instead of red, but, as I said, I'm not colorblind. Here are the colors for reference, including an image of them under the deuteranopia filter of Color Oracle. Append[$okabeItoColorsDiverging, RGBColor[1, 0.2, 1]] ![enter image description here][1] Here is a preference set for colors that seem to show differences for all three types of colorblindness, where there are significant differences in the defaults.

To get back your own preferences, save them (`myopts = Options[$FrontEnd]`), reset the preferences in the Appearance panel of the Preferences dialog, and then restore your preferences `SetOptions[$FrontEnd, myopts`. If someone knows whether these options can be controlled through a stylesheet, that would give an alternative method for implementation. I had thought that maybe by now — maybe soon — support for color accessibility would be built into Mathematica and WL. Highlighting in the Front End is just a piece of it. As you can tell, I offer my color scheme tentatively. If I've done it all wrong, I hope someone will do it all right.

Thanks, Claude Claude Mante 2022-12-27T17:32:31Z https://community.wolfram.com/groups/-/m/t/2837847 Hello, I should begin by stating that this may not be the correct group to post in, I couldn't find a more suitable one but am open to suggestions for correcting this. I am making this discussion to talk about the "enlarge" feature for certain output fields in the Wolfram|Alpha online tool being locked behind a paywall. Not only that, but when manually zooming in, the text will not upscale in resolution to make it more readable. I understand that every business has a bottom line and that in order to continue to provide a fantastic service, some features must locked behind a paywall, but I feel as though doing this to the "enlarge" feature is a clear oversight to the visually impaired. I understand that for some output fields, this feature provides more than just the ability to zoom in, so I feel as though an appropriate resolution to make the UI more user friendly would be to ensure that text in output fields will upscale when zoomed into, just like text in any other field does. Feedback on my suggestion is much appreciated, hopefully this post meets the right people. Samuel Leo 2023-02-24T12:57:25Z https://community.wolfram.com/groups/-/m/t/1313456 Many fine *Mathematica* notebooks in English are inaccessible to users of other languages, especially to young people growing up in other languages. Translating a *Mathematica* notebook - conventionally from English into another language - involves mainly text. It better does not involve Input and Output cells that should remain in English. One obvious reason is that the program uses English. The other obvious reason is that we want students to learn to use the program (in English). The routine **NotebookTranslate** distinguishes what to translate and what not. Since translation comes with a cost, the routine also supports the prudent use of Service Credits. Educators are advised to create repositories per language for such translated notebooks, to reduce costs and to allow ease of access and version management, e.g. also when an automated translation is improved upon manually.
