Light and dark
India West remembers what it was like to see. She was born with full vision, but lost it at about 4 years old when a benign brain tumor tangled with her optic nerve. A 22-hour surgery saved her life, but took away most of her sight.
“I wasn’t used to walking through the world in the dark,” says West, 17. “It was really scary, not knowing how to rely on my other senses.”
In the years since, some vision has returned. She tests at 20/400 on the doctor’s office eye chart. That’s right at the border of severe and profound visual impairment.
West can see the sky, she says, and make out light and dark. She can identify things around her house. She uses a cane to navigate. But she can’t see faces or facial expressions. She can’t tell colors. She can’t read words on a computer screen.
Much of the world remains closed off to West, and to the visually impaired community as a whole. It doesn’t have to be that way, say West and her mother, Elena Kaltsas. In an effort to help change the status quo this past semester, West worked with U-M students to develop technologies to make life easier for the visually impaired.
A true visionary
Once a week, West traveled from Clonlara Academy in Ann Arbor to David Chesney’s Software Engineering class, EECS 481, a senior-level course on U-M’s North Campus. Chesney, an instructor in computer science and engineering, is known around campus for his Gaming for the Greater Good initiative. For nearly a decade, he’s been combining video game development, software engineering, and altruism — teaching his students to use their skills to benefit diverse populations.
At first, students focused solely on video game development, but several years ago, Chesney expanded the scope. Now, each semester students work with groups of children or individuals with disabilities to make technologies tailored to meet their needs. Chesney has involved people with autism, cerebral palsy, Bell’s palsy, and now visual impairment. He and his students see those who agree to work with them as clients.
The instructor knew West was a good fit for the role when she called him “Dave” the first time they met. She addressed him that way all semester, even while his students called him Dr. Chesney.
She owned the room, even if she found it hard to navigate.
“Dave really knows how to make this classroom complicated,” West muttered one afternoon as she moved from project to project.
“How ya’ doing, India,” a student asked her.
“I’m livin’ life!” she answered cheerfully. “Whatcha workin’ on?”
“We’ve got some cool stuff to show you,” the student replied.
Before he could, West showed off a necklace she made by herself. She offered to make him one, as long as he didn’t care what color it was.
Ideas, ideas, and more ideas
West had come to the initial class with some ideas for the students: A talking oven. A smart grocery cart that would tell you where you are in a store. A way to know where her friends are sitting in a busy lunchroom.
Given the class’ constraints, those weren’t ideas they could bring to life. But the students listened to West’s experiences and came up with their own solutions to some of her day-to-day difficulties.
Noah Duchan and his group made Smart Shelf, a talking piece of furniture that can tell West what’s on it and where, and also describe the location of open areas. To build it, they linked a Raspberry Pi computer, an Amazon’s Echo smart speaker, and an Amazon Alexa intelligent personal assistant.
Duchan demonstrates: “Alexa, ask Smart Shelf where the water bottle is.”
Alexa answers: “Your water bottle is on the right side of the top shelf.”
West is awestruck. “Oh my God!” she responds.
She tries it, asking what areas were open to set stuff down on. Alexa lists locations while Duchan looks on, smiling.
“It’s a really cool project,” Chesney says. “The students are taking this interesting off-the-shelf technology and combining it in ways the producers of the technology would never envision. That’s what we try to do here.”
If you build it…
Many of the teams will be working to give West access to other technologies they created. Projects include:
- Steereo, a Google Map-based iOS navigation app that stores favorite routes, plays sound in the direction the user is supposed to travel, and adjusts distances to number of steps. The distance-to-steps conversion idea came from West, says team member Leda Daehler. ”Many visually impaired people count steps to measure distance,” she says. “So we used the iPhone’s internal pedometer to put all the directions in terms of the user’s personal step size.” Estimated times are also in terms of the user’s pace.
- Several fun, tablet-based games that use only audio cues. Chesney says his students filled a void. “There are not many fun games that depend heavily upon only audio.”
- A standard for putting RFID tags on objects so they can announce themselves to a blind person’s smartphone as they move through a building. This project will continue in Winter 2017.
- A series of online coding lessons for people who are visually impaired. West had expressed interest in learning programming. “We looked into whether there were any coding tutorials for the visually impaired and there weren’t,” says student Gabriel Pascualy. “Programming’s a very visual thing and translating it into the context of not being able to see was difficult.
Seeing the future
West can see a future in programming — specifically in software development for the visually impaired. She’s taken a short course and volunteered to test apps for accessibility. Her work with this software engineering class may have bridged the gap in a more indirect way too.
“Working with these customers with different abilities gives students a completely different perspective on how to develop software,” Chesney says.
“There’s this computer science myth that we build this thing and then we wait in our garage and somebody shows up to buy this thing and lavish money on us. But the reality is working with a customer, someone who looks at the project and says these are the things I like and these are the things I don’t, is absolutely invaluable to a computer scientist, particularly when their usage patterns are completely different than the developers.”
Daehler, who worked on the Steereo team and graduated in December, says she’ll bring this experience with her when she starts a job at Ford in early 2017, working on autonomous vehicle systems.
“By talking with India and seeing her perspective, I started thinking about the importance of considering users different from yourself during development,” she says. “There has been quite a bit of news about the blind community and self-driving cars. Now I am much more apt to think about small things that can be implemented to make driving accessible for the blind, or other people that have a lot to gain through autonomous vehicles.”
Teach your children well
Next year will be West’s last as a high school student. She plans to continue collaborating with Michigan Engineering, working with the students who developed the standard for putting RFID tags on objects. Through the Multidisciplinary Design Program, they’ll turn the Bob and Betty Beyster building into a “smart building,” where objects identify themselves as West moves through.
And in the summer, against the odds, West will graduate high school. Less than a third of visually impaired students ever do. As a result, nearly two thirds of that population live at or beneath the poverty level.
“This is a reality that does not have to exist,” says Elena Kaltsas, West’s mom. “It’s not because blind students can’t do the work. Rather, it is due to an unfortunate reality in which many public school systems fail to embrace and integrate teaching methods that adapt to diverse and unique needs of the blind community, despite individualized special education mandates.”
To celebrate West’s achievements, the mother and daughter will head to the ocean in May, on West’s 18th birthday.
“We have a trip planned to California and I’m thinking of all the things I’ll take in visually and I’m sad that she’ll miss that,” Kaltsas says. “But she’s going to experience it in a way that I can’t. I almost think her experience will be richer than my own, as she always tunes into her environment in the most beautiful way, despite her visual loss.
“There’s never a negative word that comes out of her mouth,” Kaltsas continues. “India’s never angry, she’s never disparaging. She’s never once said, ‘Why me?’ She has only talked about her blindness as if it were a gift. She wants to leverage her ‘disability’ to create change in the world, to challenge people to think differently, to live out of the best part of themselves. I don’t know anyone else in my life who is that way. Usually, it’s the parent teaching the child, but not in this situation.”
