MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

PointerEvent.twist

The twist read-only property of the PointerEvent interface represents the clockwise rotation of the transducer (e.g. pen stylus) around its major axis in degrees, with a value in the range 0 to 359.

For devices that do not report twist, the value MUST be 0.

Syntax

var twist = pointerEvent.twist;

Value

A long value representing the amount of twist applied to the pointer.

Example

When a pointerdown event is fired, different functions are called depending on the value of the event's twist property.

someElement.addEventListener('pointerdown', function(ev) {
   if (ev.twist == 0) {
     // No twist
     process_no_twist(ev);
   } else {
     // Default
     process_twist(ev);
   }
 }, false);
