254 <p><code>ABS_TILT_X</code>: <em>(optional)</em> Reports the tilt of the tool from the surface of the
258 <p><code>ABS_TILT_Y</code>: <em>(optional)</em> Reports the tilt of the tool from the surface of the
414 tool is perpendicular to the device. A non-zero tilt is taken as an indication
416 <p>The tilt angles along the X and Y axes are assumed to be specified in degrees
419 represent a tilt up or to the left, values larger than the center point
420 represent a tilt down or to the right.</p>
421 <p>The <code>InputReader</code> converts the X and Y tilt components into a perpendicular
422 tilt angle ranging from 0 to <code>PI / 2</code> radians and a planar orientation angle
426 <p>Reporting tilt information is <em>optional</em> but recommended for stylus devices.</p>
925 <h3 id="orientation-and-tilt-fields"><code>Orientation</code> and <code>Tilt</code> Fields</h3>
932 <p>The <code>Tilt</code> field describes the inclination of the tool as an angular measurement.
933 A tilt of <code>0</code> indicates that the tool is perpendicular to the surface.
934 A tilt of <code>PI/2</code> indicates that the tool is flat on the surface.</p>
961 <p>The calculation of the <code>Orientation</code> and <code>Tilt</code> fields depends on the specified
