read with your face, not your hand
This extension allows you to scroll in Chrome by tilting your head up and down rather than having to use your precious hands to scroll. It makes heavy use of the BRFv4 facial recognition package demo version for all face tracking.
There are settings available to determine sensitivity and speed of scrolling. Do note that when you activate this on a page, Chrome asks for webcam access as if that page were asking for webcam access. This extension does not transmit any data to the pages you are visiting; Chrome just asks for webcam permission on each different website that way.
NOTE: This extension does NOT transmit any data, and all webcam data is kept in browser. Feel free to check out the github repository at https://github.com/lucasvanbramer/lazyreader/tree/master and read through the source code to verify this.
