Cal State Fullerton computer engineering students have developed “Assistive Glasses,” a hands-free wearable technology device. The glasses can help people with visual impairments detect and identify often-used objects — something a guide dog cannot always do.
Class of 2023 graduates Jeremy Chang, Abel Desoto and Rodney Nobles and their faculty adviser Kiran George, professor of computer engineering, partnered with the Dayle McIntosh Center for the Disabled in Anaheim.
What technologies does the prototype use?
The prototype uses smart technologies, including artificial intelligence, machine learning, voice recognition and a bone conduction speaker, which leaves the ear canal open, unlike traditional headphones. Desoto explained that the speakers are close to the ear and in contact with the head to amplify noise by vibrating directly on the bones.
Can this device replace a guide dog or white cane?
This type of device would not replace a guide dog or white cane, but it is an additional tool that can enhance the use of mobility devices.
How was this Wearable Technology created?
Using 3D printing technology, the team created the lightweight eyeglass frame, which holds the camera, distance sensor and bone conduction speaker.
How does the Assistive Glasses work?
The camera captures an image and determines the distance between the wearer and an object. For example, the glasses can assist an individual in finding a chair or bench to sit on or locating stairs, Desoto said.
Desoto added that pairing the glasses with a backpack to hold computer components, a power source, a microphone and a distance sensor, which helps the individual avoid bumping into other people or objects, allowed the team to use less expensive components.
What are the plans for the Assistive Glasses?
Next academic year, George’s future students will expand on the work of this year’s design team to refine and further test the “Assistive Glasses” prototype before coming up with the final product.
