This podcast is about big ideas on how technology is making life better for people with vision loss.

Today’s big idea is how the technology used in instruments that extend human vision to space is being relied on by vision technology developers in devices that help people with vision loss in everyday tasks here on Earth. Using substitute senses has allowed scientists across many fields to continue their work without the use of sight. The eSight is one such device that stimulates the remaining functioning vision to improve the quality of life for users. Dr. Roberts speaks with Charles Lim about the development of the device, the principles behind how it works, and the motivation for future improvements.

The Big Takeaways:

  • Astronomers and other scientists who are blind can continue to make meaningful contributions to their field by using substitute senses — even discovering things unseen to the human eye — especially in fields where instruments do most of the heavy lifting.
  • eSight is designed to help people with low vision; they’ve found that with the right stimuli, they can leverage the dormant portions of the eye that still have some function. It is a wearable and mobile device that maximizes the visual information provided to the brain to naturally compensate for gaps in the user’s vision.
  • As they continue to develop the device, some of the most important factors are making sure it’s comfortable, accessible for a wide range of wearers, has a long battery life, and is future-proof.
  • The ability to possibly change individual lives, and to create a more accessible world, is one of the most motivating reasons behind this technology advancement and continues to drive the developments that are on the horizon for eSight.

Tweetables:

  • “What it all means is how do we leverage the technology advances in cameras, image, sensors, and processing to allow...our users to enhance their vision through more information.” - Charles Lim, Chief Technology Officer, eSight
  • “What we did is that we converted into sound data from a gamma-ray burst. We were able to listen to small variations in the data that were not visible to the human eye.” — Dr. Wanda Diaz Merced, Astronomer
  • “Astronomers have realized that you can learn a lot about the Universe by developing instruments that can be extensions of our own senses.” — Dr. Bernard Beck-Winchatz, Astrophysicist
  • “I dream of a future where eSight can really become a natural extension of our users’ vision.” — Dr. Charles Lim

  • Interim Director of STEM Center, Professor of Physics & Astrophysics, Graduate Program Director of Physics & Astrophysics; Campus Director of Illinois Space Grant Consortium

Wanda Díaz-Merced

  • Wanda Díaz-Merced is an astronomer best known for using sonification to turn large data sets into audible sound. She currently works at the South African observatory's Office of Astronomy for Development (OAD) leading the project AstroSense. As someone who has lost their eyesight, she is a leader in increasing equality of access to astronomy and using audible sound to study astrophysical data. Wanda has been included in the list of the 7 most trailblazing women in science by the BBC.
