Rick, and the rest. I find this discussion interesting, since I myself often have tried to find a mathematical formula for some kind of operation. Searching the net, you run across a ton of cases like you Rick initially described. Either non-spoken characters, or more often, a graphical image, which is supposedly giving some interesting information to the sighted user.
Well, I don't have any really good solution. Yet, long as things are written with actual characters, you could try the Extended Dictionary app. It already holds a few symbols, like the Unicode symbols for 1/2, 1/4 and so forth, and also will by standard read things like Double-plus, and the plus-minus. Since the Extended Dictionary gives you the chance of defining a separate dictionary, linked to your browser, you could have tried defining the more commonly used characters, and saved them in your software-specific dictionary for your browser, or even for your text editor. Again, should you find this works for you, and you get some interesting entries worked out, you could always have sent me the list, and I could include it by default in the package. No, the app does not work multi-lined, so in cases where the equations run over multiple lines, you won't be helped. Yet, thought to remind you all of the capabilities of the app, in case that at least would help you out on some websites.

Several versions are mentioned in a couple of articles so far: Mathematical Notation: LaTeX, Mathematica, HTML Entities, Unicode Do you know if these are a standard font thingy and should either my browser or WindowEyes be automatically picking them up and speaking them in the correct manner? Perhaps my browser is too old, not sure.

Now, symbols seem to be represented by some kind of standardized use of tags. Do you recognize the use of the tags below as a standardized methodology of some sort and, if so, what is it called? I put in a few examples so someone might recognize something. <BeginSamples> Vector notation From Wikipedia, the free encyclopedia the common typographic convention is upright boldface type, as in \mathbf{v} OK guys here they are just displaying {V} but use a prefix tag: \mathbf ... Another example: or unwieldy, vectors are often represented with right-pointing arrow notation or harpoons above their names, as in \vec{v} Here they use a tag: \vec before the actual math of {v} ... Another example: A rectangular vector in \mathbb{R}^n can be specified using an ordered set of components, enclosed in either parentheses or angle brackets. In a general sense, an n-dimensional vector v can be specified in either of the following forms: \mathbf{v} = (v_1, v_2, \dots, v_{n - 1}, v_n) \mathbf{v} = \langle v_1, v_2, \dots, v_{n - 1}, v_n \rangle Where v1, v2, …, vn − 1, vn are the components of v. Matrix notation [ edit ] A rectangular vector in \mathbb{R}^n can also be specified as a row or column matrix containing the ordered set of components. A vector specified as a row matrix is known as a row vector ; one specified as a column matrix is known as a column vector . Again, an n-dimensional vector \mathbf{v} can be specified in either of the following forms using matrices: \mathbf{v} = \left[ \begin{matrix} v_1 & v_2 & \cdots & v_{n - 1} & v_n \end{matrix} \right] = \left( \begin{matrix} v_1 & v_2 & \cdots & v_{n - 1} & v_n \end{matrix} \right) \mathbf{v} = \left[ \begin{matrix} v_1 \\ v_2 \\ \vdots \\ v_{n - 1} \\ v_n \end{matrix} \right]= \left( \begin{matrix} v_1 \\ v_2 \\ \vdots \\ v_{n - 1} \\ v_n \end{matrix} \right) Where v1, v2, …, vn − 1, vn are the components of v . In some advanced contexts, a row and a column vector have different meaning; see covariance and contravariance of vectors . Unit vector notation [ edit ] A rectangular vector in \mathbb{R}^3 (or fewer dimensions, such as \mathbb{R}^2 where vz below is zero) can be specified as the sum of the scalar multiples of the components of the vector with the members of the standard basis in \mathbb{R}^3 . The basis is represented with the unit vectors \boldsymbol{\hat{\imath}} = (1, 0, 0) , \boldsymbol{\hat{\jmath}} = (0, 1, 0) , and \boldsymbol{\hat{k}} = (0, 0, 1) . A three-dimensional vector v can be specified in the following form, using unit vector notation: \mathbf{v} = v_x \boldsymbol{\hat{\imath}} + v_y \boldsymbol{\hat{\jmath}} + v_z \boldsymbol{\hat{k}} Where vx, vy, and vz are the magnitudes of the components of v. Polar vectors [ edit ] wiki/File:CircularCoordinates.svg It goes on to other vectors for circles etc... <EndOfSamples> Rick USA ----- Original Message ----- From: LB To: [email protected] Sent: Saturday, March 08, 2014 8:18 AM Subject: Re: WE and Advanced Math and Science Symbols Hi Rick, I guess having standard symbols for the math, then splitting each up, isolating them, then using a graphics label for each, store them in your set file and such, then go from there. Just a thought, but seems like a simple way to do it. Most equations use the sup script and such for integrals and can be messy at times but not impossible. But think standard symbols may be a problem at the publishers end. But in a set file you can sort them out based on the publishers usage. Most equations use hyperbolic math for nothing goes in a straight line in physics. That can result in lots of funny math. But keep in mind that all particles are waves and you can always wave back...:) The reality of our universe is all stuff is on a plain and that plain is infinite in nature, in other words take a book and stack it's pages on into infinity and each page is a plain, but so small you could never find it, but when trying to get them apart you kind of get a nuclear bomb, for they do not want to be bothered and have the strength to prove it. touch one part of that thin sheet and it responds back some where, the spooky thing Einstein's discovered in relativity. It is like watching a insect on the surface of a lake or body of water and watch it vibrate...surface tension. Enough about god and where he is, he is just every where. A part of each sheet stacked forever. Bruce Sent: Saturday, March 08, 2014 6:46 AM Subject: WE and Advanced Math and Science Symbols Hi: What is it about screen readers where they have so much trouble reading advanced math and, or, science characters? For example, what about the Calcus symbols or the standard ones often used in describing the EM Field variables? Has anyone ever done anything trying to write a script for say either a book reader or even internet pages to make the equations read well? I have been looking at many sites lately related to quantum mechanics and light and found many, all?, sites using equations where either I get a line of characters that dont make sense to me or a blank space where a given symbol, image?, is located within the equations. I know there are third party packages that might, repeat might, work perhaps with braille but why cant a screen reader like WindowEyes with it's attendant dictionaries be used to read these pages or books? I am wondering if the pages or software could be scripted in some way to make advanced math and science equations readable with WindowEyes. Just a consideration at this point and not even a thought of being a scripting project but just the question of why it hasent been done by the screen reader companies and if anyone has ever tried to script something to enable it for WindowEyes in the past.
