Week 12

by

This week I made some minor changes to the python script so now the generated file is in the right format. I also made some major changes to my paper and have an updated draft of it. Next week I’ll be able to get together a draft of my poster and then I should be … Read more

Week 11

by

This week I re-structured things again. I decided to look into other methods of generating a visualization and decided to separate that process out from NVDA. Under this design, the developer runs NVDA with my plugin installed and that generates a text file. Then the developer navigates to my web-based visualization tool, uploads the file, … Read more

Week 10

by

At this point, since I’m still having issues with DrawString, I decided to start looking into alternative options. My adviser recommended that I look into Tkinter again, but after some playing around with it and digging into it, I learned that Tkinter is fundamentally incompatible with NVDA because it does not produce accessible content. wxPython … Read more

Week 9

by

I found this function to create a font and played around with it until I had a version that was recognized by the GdipDrawString function. Now I have code that compiles without errors and causes no runtime errors, but the text is still not displaying (or maybe just not displaying how & where I thought … Read more

Week 8

by

This week I’ve focused primarily on drafting my final paper. So far I have a general outline of my paper (abstract –> introduction –> related work –> framework and design –> implementation –> conclusions and future work), and I’ve fully drafted the abstract, introduction, and related work sections. I have a clear idea of what … Read more

Week 7

by

This week I started playing around with creating the visualization tool piece of my project. In doing that, I learned a lot of the more finicky details of NVDA. It uses an internal installation of Python, which makes sense for users because they don’t need to already have Python installed on their machine to use … Read more

Week 6

by

I found some quirks and issues with the way NVDA works in different settings. I can now get a transcript with the appropriate details by using object review mode in Firefox, but not by navigating the objects normally or while in Chrome. This gets at the issue of “not knowing what you don’t know” and … Read more

Week 5

by

This week I’ve gotten minorly stuck. I know that NVDA is able to grab — and speak — certain information about the data visualizations I’ve created(it might say, for example, “graphic New York” when I navigate to a point representing the population of New York). But when I try to grab information about those navigator … Read more

Week 3

by

This week I revised my proposal, framework and timeline. These revisions are summed up in my presentation for this week (slides can be found here).

Week 2

by

In this past week, I’ve found and simplified 2 types of data visualizations that I think would be useful for testing purposes: a slopegraph and a bubble graph. I’ve run some preliminary tests with NVDA on them to see how it’s trying to process them and developed basic plans on how to process that information … Read more

Flannery Currin Week 1

by

This past week I reached out to Dave and he agreed to be my mentor for this project and prepared my presentation slides based on my project proposal. I dug into the NVDA developer’s guide and walked through some basic examples of creating and testing NVDA add-ons, so now I have a better understanding of … Read more
