What's New

• Allow access to Leap Motion tracking data from UWP and AppContainer applications

• Control panel setting 'Allow Web Apps' persists

• Control panel setting 'Manual Orientation' Setting persists

• Fixed an intermittent crash of LeapSvc.exe during power cycle

• Fixed an issue where the SHA256 was not computed correctly on Intel Ice Lake CPUs

• Fixed an intermitted failure to detect Rigel/SIR170

• Fixed an issue during shutdown of LeapSvc, where shutdown requested within seconds after startup

What's New

• Greater finger dexterity and fingertip precision

• Better hand pose stability and reliability

• Faster and more consistent initialization

• Smoother hand and finger movements

• Improved tracking fidelity on backgrounds and bright lighting

• More accurate shape and scale for hands

• Significantly improved performance on embedded “Rigel” devices

• LeapC is now the officially supported API included in the SDK. LeapAPI has been deprecated

• Changed the fingertip location in LeapC applications such that the point defines the center of a sphere whose edge is at the fingertip. Previous output was defined such that the point was at the edge of the fingertip

• Removed LeapCSharp and associated functionality from the SDK. It can now be found as part of UnityModules

• Removed Leap.dll, all associated language bindings (LeapPython, LeapJava, Objective-C) and samples

• Added a feature that pauses the device when no clients are connected (note: the Leap Control Panel is a client)

• LeapC makefile now generates all the samples correctly

• Fixed a hang at service shutdown

• Fixed an issue where hands could initialize on top of other hands

What's New

What's New

• Improved initialization speed
• Improved stability of tracking some poses
• Better tracking and initialization in desktop mode
• Updated Unity Visualizer to fix a latency issue
• Official LeapC documentation in the SDK package
• Various changes to LeapC including:
  • Added LeapPixelToRectilinear()

  • Added invalid and unknown device types
  • Renamed eLeapDeviceType to eLeapPID
  • Added record to file and playback from file
  • Added 3x3 Matrix struct
  • Added quaternion to LEAP_PALM to represent orientation
  • Added LeapInterpolateFrameFromTime() function

• Significantly reduced the number of false hands appearing on background objects

• Improved initialization in complex backgrounds and at longer distances

• Addressed an issue where the hand can become detached at higher hand velocities

• Addressed a rare service hang while idling for several hours

• Addressed an issue with the VR Visualizer showing destop mode when using HMDs

• Addressed a rare crash issue when restarting the service

• Addressed a small memory leak after pausing/unpausing the service many times

• Added in the LeapCSharp .NET 3.5, 4.0 and 4.5 DLLs
• Addressed a judder issue in LeapC when application render FPS and tracking FPS were out of sync
• Improved initialization when running at lower frame rates
• Better tracking and higher FPS while in robust mode
• Improved tracking on the edge of the field of view
• Adjusted the gamma in the VR Visualizer when in Robust Mode
• Added an FPS counter in the VR Visualizer
• Updated the VR Visualizer to support Oculus 1.3
• Also updated the VR Visualizer to support HTC Vive

• Fixed a service crash when triggering device auto-orientation after disconnect/reconnect
• Fixed a communication issue with the service and control panel after closing the Unity Editor
• Fixed a Unity crash after editing scripts in Unity Editor while a Leap scene is running
• Report Software Issue in the Troubleshooting section of the control panel functions properly again
• Resolved an issue that caused device auto-orientation to stop working occasionally
• Manual device orientation button from the control panel functions again
• Software log reports device orientation and when HMD/Desktop mode is triggered

• Rewrote the .NET API wrapper around LeapC
• Better tracking when hands are occluded or touching
• LeapC PinchAPI and GrabAPI values no longer return 0
• Resolved the corrupt characters appearing in software log
• Resolved the hitching issue seen when running apps
• Resolved a crash when multiple clients were connected at service start
• Resolved a crash related to calibration

• Greater robustness to cluttered backgrounds and ambient light interference
• Enhanced tracking range that extends to the full length of your arms
• Faster and better initialization for all hands
• Lower latency
• Significantly improved grab-and-drop interactions
• Lower overall CPU usage
• Much better finger flexibility allowing for better poses
• Better tracking on the edge of the field of view
• Added a VR and PC visualizer to the tray menu
• Various control panel updates
• The Unity assets now use a C# binding to a C-language library rather than the SWIG-generated C++ bindings. The new C# API is slightly different then the previous one, especially for images. Currently this new C# API is only used in Unity
• Deprecated Tools
• Deprecated Gestures
• Deprecated Motion APIs (Frame and Hand translation, rotation, scale and related probability estimates)
• Tracking now automatically resumes after recalibration on Windows
• Added the setPaused() API
• Added the isLightingBad() API
