"On the Sofa for YouTube" is a Chrome extension that has been featured by the Japanese media outlet "Mado no Mori." It allows you to adjust playback position (by various time increments), playback speed, and volume simply by using the mouse wheel over a transparent UI located at the edge of the screen. Because clicks and drags pass through the transparent UI, you can continue to use the website exactly as usual. A patent is currently pending for this transparent UI.
