Real-time sign language recognition for a webcam or screen share that turns hand signs into text and speech in the browser.
Hand Wave is a browser-based tool that recognises sign language in real time from either a camera feed or a shared screen. It uses on-device computer vision to detect hand shape and motion and streams the recognised signs out as text (and optionally speech) so that Deaf and hard-of-hearing users can be understood in video calls, live streams, and in-person interactions when paired with smart glasses or a phone camera. There is no install — the recogniser runs locally in the tab, which keeps video off the network. Hand Wave is designed and built by an independent developer, Aadi Sanghvi.

Hand Wave is an innovative real-time sign language recognition tool that transforms hand signs into text and speech using a webcam or during screen sharing.

Hand Wave is an innovative tool that enhances communication between Deaf and hearing individuals by translating sign language into text and speech. Here’s how it works:
Live Camera Recognition: The tool uses your device's webcam to capture sign language gestures. This feature works seamlessly without the need for additional software installations, making it highly accessible.
Screen Share Recognition: Users can share their screens during video calls (such as Zoom or Google Meet). Hand Wave recognizes signs made during the call and provides live captions, ensuring that Deaf participants can follow the conversation without missing any critical information.
Text and Speech Output: Once sign language is recognized, Hand Wave emits the corresponding text captions, which can also be vocalized using speech synthesis. This dual output ensures that both Deaf and hearing users can engage effectively.
On-Device Vision: The recognition model runs directly in the browser tab, meaning that video streams are not sent to external servers. This on-device processing enhances privacy and security for users.
Zero-Setup Web App: Hand Wave is user-friendly; it opens in a browser with two simple buttons: "Start Camera" and "Share Screen." This straightforward interface allows users to quickly initiate communication.
Assistive Wearables: Hand Wave can also be paired with smart glasses, enabling real-time translation of sign language into audible speech for hearing individuals, further bridging communication gaps.

Screen Share Recognition: Ideal for virtual meetings, this feature allows Hand Wave to interpret and caption signs made by users during screen sharing. This is particularly useful for educators and professionals who need to include sign language interpretation in their presentations or lectures.
Text and Speech Output: Once sign language is recognized, Hand Wave can convert these gestures into readable text, which is displayed on-screen for viewers. Additionally, the application can vocalize the recognized signs, providing an auditory option for those who prefer listening.
On-Device Vision: Unlike many applications that rely on cloud processing, Hand Wave's model operates directly in the browser. This means that the video stream remains private, ensuring user data security and compliance with privacy regulations.
