For many of ____ however, access still remains an issue.

Here are two teenagers who presented new inventions to tackle the issue at an international ____ competition.

While thinking ____ her homework, Seoyoung Jun closed one eye and successfully picked up her pencil holder.

At that moment, she realized that orienting ____ in a 3D space didn’t require both eyes.

This surprised ____

With research, she learned that the brain can process 3D information without any vision ____ all.

And with that, the idea for a new device for ____ with visual disabilities was born.

Those who have lost sight get their spatial information mainly from touch, ____ vision.

She based her new navigation device on this ____

This little device sends a beam of infrared light to gather 3D information about what may lie around ____ user, including walls and furniture.

The bounced beam conveys that information to the device, which then raises little pins to ____ where those obstacles are.

By “reading” the positions and heights of those pins, the user can understand the arrangement of structures and ____ lying ahead and navigate around them.

The heart of this device is a 3D depth sensor connected to a ____ computer.

Seoyoung coded the computer to control the nine motors lined up in three rows of ____ so that each motor could move a pin up and down.

The sensor can scan eighteen ____ of space before it, each 0.06 m3 in size.

When it detects an obstacle in any of these blocks, the corresponding pin rises to either the ____ or high position, depending on the height of the obstacle.

By running your hand over the nine pins, you can tell where the obstacles are ____ how high they are.

When Seoyoung’s device ____ for the first time, she didn’t believe it.

To be sure it wasn’t a mistake, she shut it off and rebooted ____

When it worked again, she ____ screaming with joy.

It had been seven long months ____ research, building, and testing.

She imagines a future version that could be connected to a smartphone, ____ more pins and more height positions.

As a coder, Nand Vinchhi wanted to invent something that didn’t require a mechanical ____

One day, he was brainstorming with friends, and the group came up ____ an idea for an app that could translate sign language.

In the end, they decided not to develop ____ but Nand couldn’t stop thinking about the translator.

In just a few months, he developed an app based on artificial intelligence for translating American Sign Language (ASL) in ____ time.

Nand’s app was basically a speech-to-text app for sign language, where hand movements corresponded ____ speech.

The hardest ____ was figuring out how to make the app recognize hand gestures.

At times, he felt he ____ stuck.

When that happened, he would go ____ sleep.

For Nand, sleeping ____ it paid off.

He decided to focus on the body parts which ____ important in signing, such as individual fingertips.

Using a machine-learning program, he then taught the app to identify those ____ points in the videos he took.

When the ____ runs the app, gestures are captured by the camera.

Then, the app uses an algorithm to match the movements with words in ASL, which are turned into text and then ____ aloud.

According ____ Nand, his system now translates signs with 90.4% accuracy, and the delay from signing to translation is only about three-tenths of a second.

He imagines the technology could someday become part of existing communication ____

That could help ASL speakers communicate with those who ____ know the language.

What these inventions have in common is a creative use of technology to ____ the daily lives of people with disabilities.

Their efforts will go a long ____ toward a more accessible world for all.
