PointerEvent: tiltY property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2020.

The tiltY read-only property of the PointerEvent interface is the angle (in degrees) between the X-Z plane of the pointer and the screen. This property is typically only useful for a pen/stylus pointer type.

Depending on the specific hardware and platform, user agents will likely only receive one set of values for the transducer orientation relative to the screen plane — either tiltX and tiltY or altitudeAngle and azimuthAngle.

The tiltX angle of a pointer compared to the tiltY angle

For an additional illustration of this property, see Figure 3 in the specification.

Value

The angle in degrees between the X-Z plane of the pointer (stylus) and the screen. The range of values is -90 to 90, inclusive, where a positive value is a tilt towards the user. For devices that do not support this property, the value is 0.

Examples

This example illustrates simple accessing of the tiltX and tiltY properties.

js
someElement.addEventListener(
  "pointerdown",
  (event) => {
    process_tilt(event.tiltX, event.tiltY);
  },
  false,
);
