South Korean researchers have developed WRSLT, a wireless sign-language translator based on seven sensor rings. The device is worn on the fingers and converts gestures into text in real time. Unlike most existing solutions, the system does not need gloves, wires, or individual setup for each user.
Each ring is equipped with a miniature accelerometer that tracks finger positions and hand movements. The data is transmitted via Bluetooth to a smartphone or computer, where an AI model analyzes the gestures. The technology supports American Sign Language (ASL) and International Sign Language (ISL).
During testing, the system achieved 88.3% accuracy for ASL and 88.5% for ISL. The model was tested on people whose data had not been used in training, confirming that the system can work with different users without additional calibration.
WRSLT currently recognizes 100 words for each language. The next stage of the project is to make the rings smaller and expand the vocabulary.
If the field continues to develop, communication between sign-language users and everyone else could become much easier within a few years — without screen intermediaries, bulky devices, or the feeling of using "special equipment."
