What does "Fingerspelling" mean?
Table of Contents
Fingerspelling is a way of spelling out words using hand signs in sign languages, especially in American Sign Language (ASL). Instead of using signs that represent whole words, fingerspelling uses specific hand shapes for each letter of the alphabet. This method is useful for expressing names, places, or any words that do not have a specific sign.
Challenges in Fingerspelling
Fingerspelling can be tricky because it involves a lot of quick movements and is often used in combination with other signs to form sentences. Recognizing fingerspelling accurately is important for translating sign language into spoken English and vice versa. Current systems are working to improve how well they can understand fingerspelling in the context of full sentences.
Data Collection for Improvement
To help improve fingerspelling recognition, researchers have created large datasets that include many examples of fingerspelling. One such dataset, FSboard, contains over 3 million characters of fingerspelling gathered from Deaf signers using smartphones. This collection allows developers to test and refine their models for fingerspelling recognition, making them more effective in real-world use.
Future Directions
As technology continues to grow, fingerspelling recognition will remain a key part of building better sign language translation systems. By improving how fingerspelling is understood, these systems can help bridge the communication gap for Deaf and Hard of Hearing individuals.
