Experiencing the Total Solar Eclipse in a New Way: How Technology is Making it Accessible for the Visually Impaired

A total solar eclipse presents a unique and extraordinary opportunity, and with recent technological advancements, even individuals who are blind or visually impaired can partake in the experience through hearing and touch. On April 8, a total solar eclipse will be visible across North America, and individuals who are blind or visually impaired will have access to sound and touch devices at public events, enabling them to engage in this celestial event.

Yuki Hatch, a visually impaired student and astronomy enthusiast from Austin, Texas, conveyed her enthusiasm for the chance to witness the eclipse. She and her classmates at the Texas School for the Blind and Visually Impaired are looking forward to utilizing a small device known as a LightSound box, which translates fluctuations in light into auditory signals. The device emits notes from various instruments, such as flutes and clarinets, as well as clicking sounds, corresponding to the changing levels of sunlight as the moon obscures the sun.

The LightSound device is the outcome of a collaboration between astronomer Wanda Díaz-Merced, who is blind, and Harvard astronomer Allyson Bieryla. Initially introduced during the 2017 total solar eclipse, the device is now being distributed to locations hosting eclipse events in Mexico, the U.S., and Canada.

Furthermore, the Perkins Library intends to stream the altering tones of the LightSound device over Zoom, enabling its members to listen online or via telephone. Many of the library’s elderly members have vision impairments due to aging, and the initiative aims to enhance the accessibility of the solar eclipse experience for all.

Moreover, the Indiana School for the Blind and Visually Impaired has integrated the use of the Cadence tablet from Indiana’s Tactile Engineering into its curriculum. This tablet allows students to perceive graphics and movie clips through touch, and it will be available to attendees at NASA’s significant eclipse-watching event at the Indianapolis Motor Speedway.

Thanks to these technological innovations, students who are blind or visually impaired now have the chance to participate in the rare and thrilling experience of a total solar eclipse. Not only do these devices make the event accessible, but they also add a new dimension to the way it can be experienced, aligning with the belief that the wonders of the sky should be accessible to all.

The dedication of individuals and institutions to ensure the accessibility of the eclipse for all individuals is truly commendable, reflecting the significance of inclusivity and diversity in all areas of life and learning. As the world prepares for the total solar eclipse on April 8, it is heartening to witness the strides taken to ensure that everyone, regardless of their visual abilities, can partake in this extraordinary natural phenomenon.
