For the first time in nearly 100 years, a total eclipse crossed the sky over the United States, unifying millions of spectators in one of the year’s most anticipated and now photographed events. The iconic images are everywhere -- mirrored eye-glassed faces staring up in unison and with mouths agape, children peering through homemade cereal box “eclipse viewers,” the moon and sun approaching, magically meeting, then parting. 

For those with sight, it was, well, quite the sight. But what about for those who are blind or have low vision? 

Staff members of the Carroll Center for the Blind in Newton experienced the eclipse using senses other than sight through a combination of braille, a printing process called thermoform, streaming radio and a new phone app.

For the event, they're using a NASA created guide, "Getting a Feel for Eclipses," which allows persons who are blind or have low vision to learn about the eclipse.

This tactile guide is in braille and printed with a 3D-like process called "thermoform," allowing a person to explore the different stages of the eclipse through touch.

The staff also used a first-of-its-kind app called "Eclipse Soundscapes." Designed by the Smithsonian Astrophysical Observatory, NASA and WGBH's National Center for Accessible Media, the GPS-driven app allows persons who are blind or have low vision to experience the eclipse through narration and vibration.

Using his smartphone, David runs his fingers across the middle of the screen and over a diagram of an eclipse. Vocal descriptions, tones and vibrations emanating from the app map out the progression of the eclipse via shifts in darkness and light.

In addition to illustrating the different stages of an eclipse, the guide includes a tactile diagram of the path the eclipse will take over the United States. Here Eileen runs her fingers along the path.

As the staff passed around the guide, Brian Charlson used his phone to share a descriptive narration of the eclipse via a live audio stream on ACB (American Council of the Blind) Radio.

Throughout the year, ACB Radio provides a wide array of audio programming, available worldwide, for persons who are blind or who have low vision.
