BYOAD: Tactile Interpretation Exhibit: Weekly Updates

Professional Advice

Chris M. with the Intrepid Sea, Air & Space Museum gave me some great fabrication advice for getting started with this project. He recommended that I look into Aspire and VCarve for CNC routing as these are the programs used within his shop. Chris also recommended two materials that I should consider for this project:


Starting with the 2.5D Tactile Graphic of Charles Willson Peale's Portrait of George Washington which is part of Macculloch Hall Historical Museum's collect.

Chris recommended looking to have the entire face depicted in the graphic. By having markers (eyes, mouth, nose), the BLV reader can better make out the other parts of the face. Specifically, we are aim to have the jowls of GW stand out in this graphic. Without the markers, that feature will have no points of reference.


The first step will be turning the 2D portrait into topographical layers (organic shapes). I aim to start with paper then move to a laser cut cardboard version for testing this week.

Step 1: Turn Color Image into Black and White Image using Photoshop

I tested out a few filters in order to get the various levels within the portrait.

  1. New Adjustment Layer: Black and White

    I wasn't sure how to use this even though it shows exactly what I am looking for.

  4. Image Adjustment: Polsterize

    Using the following video, I explored posterize to find the best option.

    I also found the following resources. Unfortunately, I do not have student access to Rhino through NYU so this option will not work at this time.

    After all that testing, I think I am going to test out the following:

    After expanding the object and ungrouping the path, I had a lot of individual lines associated with this image. Too many to spend grouping to create the necessary lines for the amount of time available.
