The Hinge sensor is a common custom sensor on laptops. It calculates the angle between the lid (screen) and the base (keyboard). In addition, it also exposes screen and the keyboard angles with respect to the ground. Applications can easily get laptop's status in space through this sensor, in order to display appropriate user interface.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
