Google has joined the Universal Stylus Initiative (USI), a group of over 30 companies committed to supporting an "industry standard, non-proprietary, active stylus protocol."

The USI 1.0 spec determines how the stylus sends data to the connected screen, including information like pressure levels, button presses, and eraser operation. The stylus can also store preferences such as pressure levels and ink color.
