[accessibleimage] Re: Picture Perception and Interpretation


Hi,
I was thinking about systematizing the ideas behind tactile drawings. Thought it would be helpful. I thought the article was useful in clarifying part of the issue.
That way could be helpful in making the specifications for a drawing or set of drawings. (When I had a number not followed by anything, I just meant that the list could continue)

Good to get feedback, changes, suggestions etc.

Levels of difficulty/abstraction (?)
1. actual objects / very realistic 3-d models / scaled models
2. simple 2d drawings
3. 3d drawings, perspective 2 dimensional representation, symbols
4. visual metaphors etc
5.......

Accompanying, addition, supplementary information to a tactile
1. exploration
2. description
3. discussion
4. comparison
5......

Terms taken from other fields:

1. Generalization (cartography) see an earlier mail
2. Clutter
3. iconic / symbolic
4. ....


Resulting graphic
1. Interactive - where the individual reads self
2. creating self - where the individual creates self
3 lead - where the hand is guided
4. peer to peer - where a member of one group creates for the group
5......


What is used as "description" gives "nuance" in a graphic

1. line elements (line,point,polygon)
2. texture
3. height
4. movement
5. sound
6. smell
7......

User/audience
1 designed for one individual
2. lowest common denominator - (for want of a better term) understood by all, perhaps also reproducible by all production means(?) embossers, swell etc.
3.increased amount of information - fewer users
4.....




>>In general, I have found that even fully sighted immigrants and refugees who
come from other cultures, whether they are literate or not, sometimes find
the specific kinds of abstractions presented in instructional pictures and
graphics in U.S. culture to be ambiguous and even confusing.


This is a general problem with graphics, it is always a challenge to make information graphics understandable. Making visual graphics is just as challenging as making tactile graphics, the difference is there are many more people making them and there is I think a longer history of debate around the issue. The developing environment for visual graphics is much greater. So if one designer gets it wrong he/she will have 1000s of other designers coming with improvements and etc (perhaps a exaggeration) and too the supporting industries are much larger (printing houses, hardware manufacturers, etc) and also come up with new solutions.

What do you think?

Lisa
