Yes, completely. It exists as a free alternative to eye-gaze keyboards that cost thousands of dollars: your webcam is the sensor. No account, no ads. ### How do I type with it? Point with your index finger to highlight a key on the side-panel keyboard, then pinch your thumb and index finger together (or hold still) to press it. The key is typed into the focused field of the active tab. ### Where does it work? In any web page inside Chrome: Google Docs, Gmail, search boxes, chats, web apps. It types into web pages, not the browser's own address bar or apps outside Chrome. ### Does my camera video leave my device? No. Frames are analyzed in your browser by a bundled hand-tracking model and discarded. The extension makes no network requests; there is no account and nothing is recorded. ### What keyboard layouts are available? QWERTY, ABC (alphabetical), and a frequency-ordered layout that puts common letters closest to the center. You can also choose pinch-only, dwell-only, or both, and adjust the dwell time. ### Is this a medical assistive device? No. It is a home typing aid. If you need a certified assistive device, talk to an assistive-technology professional. ### How do I install it? Download the extension folder, open chrome://extensions in Chrome, turn on Developer mode, click Load unpacked, and pick the folder. Click the extension icon to open the side panel, then Start camera. ### Does it work offline? Yes. The hand model and all code are bundled with the extension, so it works with no internet connection. --- Interactive version: https://toollantern.win/hands-free-air-keyboard/
