AirTouch

AirTouch is a macOS application that transforms your built-in or external webcam into a hands-free gesture controller for your entire Mac. Instead of buying extra hardware or wearables, you can move the system cursor, click, scroll, switch applications, close windows, and trigger actions across the system simply by making physical hand gestures in front of your camera.

Privacy is built in from the ground up. AirTouch processes all images entirely on-device through the Apple Neural Engine, converting each camera frame into 21 geometric hand landmarks and discarding them within 5 milliseconds, so nothing ever leaves your Mac.

It also includes an advanced dictation feature called Telepath. Simply place two fingers near your temple and start talking, and you can dictate text at up to 220 words per minute, making writing and messaging faster than ever.
