Friends with Low vision If you have low vision and you are on this list, you probably have good computer skills. Most of you are professionals like me. Owing to a general lack of good tools for low vision, I hack a lot. This is mostly so that I can read. So, here is what I do. What do you do? First I use my Mac Book Air. It has free screen reading and zoom. The Safari browser enables alternative style sheets easily. It also has good text only enlargement. Firefox is also good, but using alternative style sheets is more awkward. Voice Over - The Mac screen reader works much line all screen readers. It is not at all oriented to people with low vision. However you can adjust your input, and trick it into a pretty good rendering of the text. It does talk too much and makes it very hard to use a mouse. The Mac Zoom feature is excellent for filling our forms, reading pop ups, and reading small menus. It works line most zoom features with all the strengths and limitations. I use alternative style sheets that I author. Anyone who wants one to start their own, just ask. Some pages are just too flawed for alternative style. CSS sprites and generated content are a serious problem for a general style sheet. Changing background color can render a page inoperable. For many pages I just use text-only enlargement. Pages with table layout can ruin this accommodation by elongating the horizontal line length an preventing word wrapping. The recent discussion about the AFB word wrapping issues result from this design flaw. I also use a Kindle. I like it much better than an iPad. This is because you can have a horizontal view that is one column. The very-very large print setting can work better in horizontal mode. As far as the Kindle menus are concerned I just use my 700% reading glasses. Bookshare books convert well to a kindle format. Just take the xml file and convert it to html. This is easy. Juse read it into a browser and save the generated text. Seamonkey is perfect for this. Just read in the xml file, change to edit mode and save the file as html. The Bookshare books all come with an XSLT file that converts the xml to html for display in browsers. An old W3C member, Harvey Bingham was a writer. Since, Bookshare records the entire NY Times bestseller the text-to-speech issue is a non-issue. Use Calibre to convert from html to mobi. Mobi is a format the Kindle will read. For PDF, I convert it to HTML. Then I change all the occurrences of "style=" to "title=". The Acrobat converter produces no "title" tags. Then I apply my own style sheet to the resulting HTML. This is crude but it works 99% of the time. I even converted the ECMA 5 standard that way. Well that is what I do.
