+The TOUCH and WIDTH parameters have a geometrical interpretation; imagine
+looking through a window at someone gently holding a finger against the
+glass.  You will see two regions, one inner region consisting of the part
+of the finger actually touching the glass, and one outer region formed by
+the perimeter of the finger. The diameter of the inner region is the
+ABS_MT_TOUCH_MAJOR, the diameter of the outer region is
+ABS_MT_WIDTH_MAJOR. Now imagine the person pressing the finger harder
+against the glass. The inner region will increase, and in general, the
+ratio ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR, which is always smaller than
+unity, is related to the finger pressure. For pressure-based devices,
+ABS_MT_PRESSURE may be used to provide the pressure on the contact area
+instead.
+
+In addition to the MAJOR parameters, the oval shape of the finger can be
+described by adding the MINOR parameters, such that MAJOR and MINOR are the
+major and minor axis of an ellipse. Finally, the orientation of the oval
+shape can be describe with the ORIENTATION parameter.
+
+The ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a
 finger or a pen or something else.  Devices with more granular information
 may specify general shapes as blobs, i.e., as a sequence of rectangular
