For my first experience using the Tactile Viewer, I chose graphics I was already familiar with to make the process easier. I selected a map of Guatemala and the Mona Lisa image.
Starting with the map of Guatemala, its simple outline made it easier to identify, even at a smaller size. Using the magnification feature allowed me to explore different areas of the map in more detail. However, when I used the shortcut to display the lower part of the map, the Monarch device showed nothing. I assume this was due to the presence of large blank areas outside the graphic.
Exploring the Mona Lisa was a different experience. This graphic had more detail, and while I was able to recognize some facial features, not all were easily distinguishable. Magnifying the image helped to some extent, but I didnât notice a significant difference between increasing or decreasing the level of detail. The inverted Braille mode was particularly interestingâalthough it didnât help much with the Mona Lisa, it worked better with the map of Guatemala. I found that inverted Braille may be more effective for exploring maps.
Navigating the graphics using the D-pad was not very efficient. It was slow and required pauses for the tactile display to catch up. I believe the D-pad would be more productive if it allowed movement by full screen sections. For example, if a graphic spans six full screens horizontally, pressing the left or right directional buttons could move between those segments. Similarly, the up and down buttons could be used to navigate through vertical sections. This approach would make the exploration faster and more intuitive.
I have used embossed tactile graphics before, and each methodâhard copy, and digitalâhas its pros and cons. Hard copies, once created, provide immediate access without the need for multiple steps, offering a direct tactile experience. However, they are limited in detail and size. In contrast, digital graphics allow for zooming in to explore finer details and can provide immediate access without having to wait for a physical copy. This is a major advantage in time-sensitive situations.
That said, context matters. For example, if I were learning to navigate a local area using a map created by an Orientation and Mobility (O&M) specialist, I would prefer a hard copy. It offers a more immediate and stable reference point for that specific use case.
