◆
Enumerates the names of the bones.
Since 2.0
Enumerator The metacarpal bone connecting to the wrist.
The first finger phalanx bone.
The middle finger phalanx bone.
The finger phalanx bone at the end of the finger.
◆
The errors that can cause a device to fail to properly connect to the service.
Since 3.0
Enumerator The cause of the error is unknown.
Since 3.0 The device has a bad calibration record.
Since 3.0 The device firmware is corrupt or failed to update.
Since 3.0 The device is unresponsive.
Since 3.0 The service cannot establish the required USB control interfaces.
Since 3.0 Not currently used.
Since 3.0
◆
The available types of Leap Motion controllers.
Since 1.2
Enumerator A standalone USB peripheral.
The original Leap Motion controller device.
Since 1.2
◆
Enumerates the joints of a finger.
The joints along the finger are indexed from 0 to 3 (tip to knuckle). The same joint identifiers are used for the thumb, even though the thumb has one less phalanx bone than the other digits. This puts the base joint (JOINT_MCP) at the base of thumb's metacarpal bone.
Pass a member of this enumeration to [LeapPointable jointPosition] to get the physical position of that joint.
Note: The term "joint" is applied loosely here and the set of joints includes the finger tip even though it is not an anatomical joint.
Since 2.0
Enumerator The metacarpophalangeal joint, or knuckle, of the finger.
The metacarpophalangeal joint is located at the base of a finger between the metacarpal bone and the first phalanx. The common name for this joint is the knuckle.
On a thumb, which has one less phalanx than a finger, this joint index identifies the thumb joint near the base of the hand, between the carpal and metacarpal bones.
Since 2.0 The proximal interphalangeal joint of the finger.
This joint is the middle joint of a finger.
The proximal interphalangeal joint is located between the two finger segments closest to the hand (the proximal and the intermediate phalanges). On a thumb, which lacks an intermediate phalanx, this joint index identifies the knuckle joint between the proximal phalanx and the metacarpal bone.
Since 2.0 The distal interphalangeal joint of the finger.
This joint is closest to the tip.
The distal interphalangeal joint is located between the most extreme segment of the finger (the distal phalanx) and the middle segment (the intermediate phalanx).
Since 2.0 The tip of the finger.
Since 2.0
◆
Enumerates the names of the fingers.
Members of this enumeration are returned by [LeapFinger type] to identify a Finger object.
Since 2.0
Enumerator The thumb.
The index or forefinger.
The middle finger.
The ring finger.
The pinky or little finger.
◆
The possible gesture states.
Enumerator An invalid state.
The gesture is starting.
Just enough has happened to recognize it.
The gesture is in progress.
(Note: not all gestures have updates).
The gesture has completed or stopped.
◆
The supported types of gestures.
Enumerator An invalid type.
A straight line movement by the hand with fingers extended.
A circular movement by a finger.
A forward tapping movement by a finger.
A downward tapping movement by a finger.
◆
Enumerates the possible image formats.
The [LeapImage format] method returns an item from the LEAP_IMAGE_FORMAT_TYPE enumeration.
Since 2.2.0
◆
Defines the values for reporting the state of a Pointable object in relation to an adaptive touch plane.
Since 1.0
Enumerator The Pointable object is too far from the plane to be considered hovering or touching.
The Pointable object is close to, but not touching the plane.
The Pointable has penetrated the plane.
◆
The supported controller policies.
Since 1.0
Enumerator The default policy.
Since 1.0
Receive background frames.
Since 1.0
Receive raw images from sensor cameras.
Since 2.0.5
Optimize the tracking for head-mounted device.
Since 2.1.3
Allow pausing and unpausing of the Leap Motion service.
Since 2.2.0
◆
Enumerates the possible data types for configuration values.
The [LeapConfig type] property returns an item from the LeapValueType enumeration.
Since 1.0
◆
const float LEAP_DEG_TO_RAD
The constant ratio to convert an angle measure from degrees to radians.
Multiply a value in degrees by this constant to convert to radians.
Since 1.0
◆
The constant pi as a single precision floating point number.
Since 1.0
◆
const float LEAP_RAD_TO_DEG
The constant ratio to convert an angle measure from radians to degrees.
Multiply a value in radians by this constant to convert to degrees.
Since 1.0
