Undergraduate students at the University of Washington have created a groundbreaking wearable device to help improve communication for individuals who are deaf and hard of hearing. The SignAloud smart gloves created by Thomas Pryor and Navid Azodi will translate American Sign Language into text and spoken words almost instantly.
The concept behind SignAloud is relatively simple but significant by allowing people who do not know American Sign Language to communicate with those who are using it. The smart gloves collect data about how the user’s hands move and how the person communicates with ASL to become a true representation of what the user is signing.
How the Technology Works
The SignAloud technology uses multiple sensors located on the fingers and palms of each hand to measure angular movements, finger bends, and the orientation of your hands in space. When these movements are collected, they are sent to a central location where the data is interpreted through a sophisticated recognition system that was developed specifically for ASL. Once processed, the ASL can be output either through a handheld or a stationary speaker.
SignAloud stands out because its creators prioritized ease of use from the start. The smart gloves offer a practical, streamlined design that feels less intrusive than many traditional assistive devices, making them more comfortable and suitable for everyday wear.
Barriers To Communication
People who use sign language face communication gaps every day. These challenges become more noticeable when interpreters are not available, making routine interactions harder both within the deaf community and with non-signers. SignAloud helps address this issue by converting sign language into spoken words in real time. This allows users to communicate more directly and confidently in schools, workplaces, hospitals, care facilities, and public spaces. By translating signing into speech, SignAloud makes conversations smoother and reduces the barriers that often limit meaningful interaction.
At present, SignAloud only translates from sign language into spoken language, but as the work progresses, so will the user’s ability to utilize the device for other purposes. There are many potential improvements of the device, including increased speed and/or accuracy of translation, and an increase in the number of signs translated by the device.
Future Purpose
The objective of the SignAloud team is developing the glove design to make the gloves less bulky, less expensive and able to be worn as part of everyday life. Their work clearly indicates how proper engineering can provide solutions for communication problems that have existed for a long time.
SignAloud continues to grow, and its work provides evidence that design with a purpose and empathy results in developing viable relationships between and among various groups and communities.
