Expand description

A force description of a Touch input.

Variants§

§

Calibrated

On iOS, the force is calibrated so that the same number corresponds to roughly the same amount of pressure on the screen regardless of the device.

Fields

§force: f64

The force of the touch, where a value of 1.0 represents the force of an average touch (predetermined by the system, not user-specific).

The force reported by Apple Pencil is measured along the axis of the pencil. If you want a force perpendicular to the device, you need to calculate this value using the altitude_angle value.

§max_possible_force: f64

The maximum possible force for a touch.

The value of this field is sufficiently high to provide a wide dynamic range for values of the force field.

§altitude_angle: Option<f64>

The altitude (in radians) of the stylus.

A value of 0 radians indicates that the stylus is parallel to the surface. The value of this property is Pi/2 when the stylus is perpendicular to the surface.

§

Normalized(f64)

If the platform reports the force as normalized, we have no way of knowing how much pressure 1.0 corresponds to – we know it’s the maximum amount of force, but as to how much force, you might either have to press really hard, or not hard at all, depending on the device.
