Rumble Map

Eclipse Soundscape
The Eclipse Soundscapes’ app features an interactive "rumble map," which uses a smartphone's touch screen and vibrational feedback to demonstrate the physical qualities of an eclipse. The rumble map displays photos of the eclipse at various stages. When users touch the image, the app reads the greyscale value of a pixel underneath their finger, and vibrates the phone with a strength relative to the brightness of the section.
