Hello Timothy! As you've already discovered, assistive technology that makes electronic content accessible to those who are blind can be significantly different from what people with low vision require.

Am I correct in assuming that you'll be creating and reading diagrams electronically? Are you using any screen magnification software now like Zoomtext, Magic, or Window Eyes?

Subject: [Athen] Developing and reading Accessible UML and ER diagrams

Hi, I am a visually impaired computer science student, and I am taking a relational database class this quarter as well as a design patterns class. In both classes, I will need to be able to create and read diagrams used for modeling.

In my design patterns class, I will be learning UML, used for modeling object oriented programming. My relational database class will require me to learn ER diagrams, for modeling databases.

>From what I understand, UML and ER diagrams are similar, so hopefully I can find a solution that will work for both.

I am searching for a solution for how I can make these diagrams accessible. Someone suggested to me Microsoft Visio, but I have never used it, and I am not certain if it can do everything I need it to and be accessible. I did a google search on UML for blind individuals, and found a lot of papers that have been written about the subject. There was some software that has been created from what I can tell, but I am having a problem locating download links for the software.

I need to be able to read diagrams that my teachers create, as well as be able to create them myself.

I found this in my searching, but from what I can tell, it only allows for reading UML diagrams. I have not tested it yet, but will soon.


Does anyone have any suggestions on how I can handle these diagrams in my classes?
