Hi James, thank you for writing in and providing examples for review. Your topic is currently under review by the TG Committee and a response will be sent shortly.
Hi David, we would like to start off by saying that [G&S 2010] provides guidelines for use and there is not just one way, but there is always a better way to transform images into tactile graphics.
After reviewing the 4 examples provided we noticed a lack of space between components of these graphics. Please consider the space between components, typically 1/8” clearance, when preparing graphics in the future. With this in mind, our top choice is example 1. Now, since this graphic is written across facing pages, you might want to repeat the vertical axis line from the first page onto the second, since tracking across the binding edge is difficult. Note, the “Year” label should be embedded in transcriber’s note indicators since it doesn’t appear in print. Additionally, the use of white space should be employed for dots that cross other textures within the graphic. This process should be used on all the examples that were provided.
Example 2: Mention of the interchanged vertical “Percentage of total population” and horizontal “Year” axis lines will suffice for transcriber’s note explanation. Additionally, this graphic is too cluttered and lacks room for navigating the page for braille readers. We do not suggest using this method.
Example 3: The graphic bars are too close together. This method seems too busy for use.
Example 4: Mention of the interchanged vertical “Percentage of total population” and horizontal “Year” axis lines will suffice for transcriber’s note explanation. These graph bars also seem to lack enough space.
Hope this helps!
