Latest Patents

The available information lists one patent for Nascimento: “Sign Language Recognition Using Parameter Keypoints.” The system captures image data of a person performing a sign and extracts keypoints from the person’s hands, arms, trunk, and face. A parameter analyzer uses these keypoints to identify characteristics such as handshape, palm orientation, articulation point, and movement.

The system generates a description of the sign, then filters and aggregates that description into a condensed form. It queries a database of known signs using dynamic time warping and retrieves the associated word.

Career Highlights

Nascimento is associated with Lenovo (Singapore) Pte. Ltd. His listed patent demonstrates an approach to sign language recognition that combines body keypoint analysis with database matching.

Collaborations
