Add features for semi-structured diagrams #18

Open shepazu opened 4 months ago

Several issues arose from the exercise of defining JIM for a semi-structured diagram of a plant cell.

Note: a semi-structured graphic means that it’s not a rigid, well-defined topography and data schema, like a line chart or scatterplot. The graphic itself should ideally still have structural elements, such as groups, titles/labels/descriptions, general organization, etc.

I made 2 versions of the graphic:

I also made an “experimental” version, in which I added some some potential features for JIM that occurred to me while I was composing this image, so I wanted to discuss them with y’all. You can get that one here:

About the graphic

This graphic is intended to mirror one that might be used in a classroom, specifically for blind and low-vision students.

The graphic is modeled on several online images of a plant-cell structure, as well as some research about plant cells to find the most pertinent aspects that should be represented.

Graphically, I looked for illustrations that had interesting tactile patterns and structures. This matters most for tactile and visual distinctiveness, but may inform haptic patterns inspired by those textures.

The graphic is deliberately drawn in a flattened, simplified style, without “3D” graphical features like shading or accents, for clarity of tactiles and haptics.

4 issues surfaced in modeling the announcement behaviors in JIM, broken out into separate issues on this repo's issue tracker, to be discussed there:
