Silentist uses the first-person perspective to recognize sign language and convert it into speech, and projects the speech into text into the palm to form a closed loop of communication. The infrared sensor detects surrounding vehicles and vibrates to ensure a safe commute. The beautiful neck wear design frees hands, protects the self-esteem of the hearing impaired, and is easy to carry. Compared with the products on the market that carry out gesture recognition from the second person perspective, Silentist pays more attention to the transmission of sign language as mother tongue and supports custom gesture recognition, allowing users to input the special meaning of specific gestures and adapt to the Internet hot words and rich emotional expression. In addition, with the help of natural language processing (NLP) technology based on deep learning, the text after gesture recognition can add adverbials, modal particles, etc., to enrich the emotional expression of the hearing impaired. The device has a self-learning function, and gesture recognition becomes more accurate with the increase of frequency of use, helping the hearing-impaired to better integrate into society. The establishment of the first person sign language recognition database provides a data basis for further development in the future.Deaf individuals often face rejection and misunderstanding when communicating with hearing people, leading to social isolation. Existing sign language recognition products mostly use a second-person perspective, and portable sign language translation devices are rare. Due to the inefficiency of text-based communication, it is difficult for deaf individuals to truly integrate into society. Additionally, in daily life, deaf individuals are at risk because they cannot hear surrounding sounds, posing significant dangers, especially in traffic. Traditional sign language recognition gloves and glasses are complex, cumbersome, and unsuitable for everyday use. Silentist addresses communication barriers fundamentally by recognizing sign language from a first-person perspective, converting it into voice, and projecting text onto the palm, forming a closed communication loop. The device also has built-in infrared sensors that vibrate to alert users to nearby vehicles, ensuring commuting safety. Its elegant and portable design not only frees up the hands but also enhances the user's self-esteem and quality of life, addressing multiple pain points faced by deaf individuals.
