If the sensors on the Leap Motion Controller are knocked out of their initial alignment, the device must be recalibrated. Poor calibration can cause:- Persistent jumpiness- Frequent discontinuities in the tracking data- Odd behavior in tracking data that occurs only in certain areas of the filed of view- Poor tracking range

To recalibrate your Leap Motion controller:

1. Open up the Leap Motion Control Panel in your system tray

2. Click on the Troubleshooting tab

3. Click on Recalibrate Device

4. Pan and tilt the Leap Motion Controller to move the cursor around to paint the screen. Watch the video below to see how to calibrate the controller.

5. Try to get a calibration score of 80 or above.

There will be times when the Leap Motion Control Panel (LMCP) will warn that a recalibration is needed. To recalibrate your embedded Leap Motion Controller (LMC):

Click/right-click on the LMC tray icon > Settings

Select the Troubleshooting tab

Select Recalibrate Device

Follow the instructions on screen

When aiming the flat reflective object at the Leap Motion sensor, try moving the object in a circular fashion with your hand without moving your arm too much. It's all in the wrist!

If you experience issues with completing the recalibration, try a larger reflective surface like a handheld mirror or a tablet

Once completed successfully, tracking needs to be re-enabled by pressing Fn + Spacebaror selectingResume Trackingfrom the Leap Motion tray icon

With a few steps, you can build your own Python 3.3.0 wrapper.

On Windows:

Building LeapPython.pyd on Windows (32-bit Python 3.3.0 for this example) :

Install Visual Studio (any of 2008, 2010, or 2012 should be fine), Python 3.3.0 for Windows x86, and swig-2.0.9.

Create an empty C++ project. Copy Leap.h, LeapMath.h, Leap.i, and Leap.lib (x86) into this project folder.

From that folder, run SWIG to generate LeapPython.cpp. For example:c:\leap_python33>"C:\Program Files (x86)\swigwin-2.0.9\swig.exe" -c++ -python -o LeapPython.cpp -interface LeapPython Leap.i

Open up the project properties, select the Release configuration, and go to the Configuration Properties -> General page. From there, set the 'Target Name' to LeapPython and set the 'Configuration Type' to 'Dynamic Library (.dll)'. ( screenshot )

Go to to the C/C++ -> General property page. Add the path containing Python.h, typicallyC:\Python33\include. ( screenshot )

Go to the Linker -> Input property page. Add Leap.lib and the full path to python33.lib, typicallyC:\Python33\libs\python33.lib. ( screenshot )

Press F7 to build. (If you hit errors such as missing symbols, this tends to come from accidentally omitting one library or mixing x86 with x64. Double-check that you have the correct Leap.lib and python33.lib (from 32-bit Python) and are building a Win32 configuration.)

Rename the output LeapPython.dll to LeapPython.pyd

If you need 64-bit Python, create the x64 configuration in Visual Studio and change some of the above steps to use x64 libraries accordingly.

The process on Mac OS X is generally easier.

On Mac:

Building LeapPython.so on Mac :

Install XCode along with its command-line tools, Python 3.3.0 for Mac, and swig-2.0.9 (likely using MacPorts).

Copy Leap.h, LeapMath.h, Leap.i, and libLeap.dylib into one folder.

Generate LeapPython.cpp withswig -c++ -python -o LeapPython.cpp -interface LeapPython Leap.i

Compile and link withclang++ -arch i386 -arch x86_64 -I/Library/Frameworks/Python.framework/Versions/3.3/include/python3.3m LeapPython.cpp libLeap.dylib /Library/Frameworks/Python.framework/Versions/3.3/lib/libpython3.3.dylib -shared -o LeapPython.so

Running the Sample Python app:

You can take your resulting LeapPython.pyd (LeapPython.so on Mac) and run the Sample application alongside Leap.py and Leap.dll (libLeap.dylib on Mac). You'll naturally have to make some changes to adhere to Python 3, such as parentheses around arguments to the 'print' function and replacing the line using the '/=' operator with:pos = pos.__div__(numFingers)

Mac command-line:

`$ python3 SamplePython33.py

Initialized

Press Enter to quit...

On Linux:

Please see Akishin's tutorial on building LeapPython for Python 3+ on Ubuntu

Conclusion

In the attached zip file I have included sample wrappers built with the above procedure, as well as a Sample.py modified for Python 3.

Our hope is that this approach will not only work for users interested in Python 3, but also serve as a solution for those who have requested other versions of Python for which we don't yet provide binaries. For example, we have heard requests for Python 2.7.1, Python 2.6.2, and even alternative builds of Python 2.7.3. We're looking for ways to best meet the needs of our Python users without letting this turn into a maintenance nightmare of Python versioning.

The Leap Motion Controller is a small USB device that plugs into your computer. Using LED lights and camera sensors, the Leap Motion Controller scans an area of roughly 8-cubic feet (2x2x2) above the device. It tracks both hands and all 10 fingers as they move through the open space between you and your computer, the special software detects your hands and fingers and translates the data into information for your computer.

With the release of the Orion software, the Leap Motion Controller can now be used with VR headsets such as the Oculus Rift and HTC Vive.

On June 30, the Leap Motion App Store was officially retired. This FAQ will answer most questions you may have.

Why are you retiring the App Store?

We launched the Leap Motion App Store in 2013 because it represented a single destination for everyone who wanted to access the latest and greatest content. This made sense at the time because the Leap Motion Controller was a standalone product. Get a controller, download the software, find apps.

But with mobile VR, were set to become a fundamental component of a larger experience. OEMs who embed our technology have their own visions for app distribution. At the same time, online distribution platforms like Steam have a large (and growing) collection of VR apps. And in the last two years, the Leap Motion Gallery has expanded as a place to find desktop and VR content. For these reasons, an app store no longer makes sense.

As a user, what happens to my App Home apps?

With the closure of the App Store, you are longer able to download new apps. The apps that you already have in App Home will continue to be available indefinitely, but cannot be moved to a new computer. However, many of your favorite apps have been made available for free on the Gallery, including GameWAVE and Geco MIDI.

As a developer, what happens to my App Store apps?

With the closure of the App Store, your apps will no longer be available to download from the Leap Motion App Store. Users will continue to have access through local installs of App Home, but will not be able to receive updates.

Can I get a refund on my App Store credits?

Anyone who purchased credits on or after 12am PT on January 1, 2017 will have their credits automatically refunded to the payment method they used. Anyone who purchased credits before April 2017 and would like a refund should contact us directly at [email protected] (as their payment method may have expired).

Will you still support the Leap Motion Controller?

Yes. We have no plans to end support for the Leap Motion Controller. The magic of our technology has always been in its software and even after nearly four years, were still exploring the hidden depths of the hardware.

When will final app payments be processed?

We will send final payments on all outstanding app balances on June 30.

Can I publish my app elsewhere?

Absolutely! We strongly encourage you to publish on your distribution platform of choice (such as Steam, itch.io, or Green Man Gaming). Leap Motion will also provide promotional support, including featured spots on the Leap Motion Gallery and our newsletter. Email [email protected] for details.

FAQs on the Leap Motion SDK Agreement

Thank you for being a member of the Leap Motion development community!

We have prepared the FAQs below to help answer questions about our SDK Agreement. The FAQs are qualified by the terms of the agreement, which you should review carefully. If you have any questions after reviewing the FAQs and the SDK Agreement, please contact us at [email protected].

What does the SDK Agreement allow me to do?

The SDK Agreement lets you develop and test Leap Motion-enabled applications using our SDK, and also gives you distribution rights for many applications - the exception is for Specialized Applications, which we explain below.

What is a Specialized Application, and why must I contact Leap Motion if I want to distribute one?

Basically, a Specialized Application is a Leap Motion-enabled application which is: (i) priced at more than US$500 (or $240/year if on a subscription or similar basis); (ii) for use with a system, machine or device (other than a PC, mobile phone or VR/AR headset), priced at more than US$500 (or $240/year if on a subscription or similar basis); or (iii) designed for use with or control of industrial, military, commercial or medical equipment, or (iv) designed or primarily used for an industrial, military or medical use.

If you would like to distribute a Specialized Application, please contact our business development team at [email protected].

We have set $500 (or $240/year if on a subscription basis) as the price limit for applications that can be distributed under the SDK Agreement because we think that above these prices the use may be so specialized that it is appropriate to have a separate agreement. The same goes for uses with other systems, machines or devices above $500 / $240.

We do not allow distribution under the SDK Agreement of applications at any price if the application is to control industrial, military, commercial or medical equipment, or for industrial, military or medical use. Again, we believe that for these uses it is appropriate to have a separate agreement.

Does Leap Motion have a standard agreement for Specialized Applications?

Because of the diverse range of potential Specialized Applications, we do not have a standard agreement. Please contact our business development team at [email protected].

Does the SDK Agreement restrict development of Specialized Applications?

No. The restriction in the agreement applies to distribution of Specialized Applications. You can still test and develop Specialized Applications.

Im a maker, and have put together something to control my drone / robot / dragon. Whats up?

In general, make away! If you are doing it for yourself, anddon'tplan to distribute it to others, you are largely free to test and develop as you like. And, if you do want to distribute your app, our restrictions apply to industrial, military, commercial or medical equipment, or to other equipment if you plan to sell it (and then, only if its priced at more than $500), or industrial, military or medical use. (Of course, wedon'tallow uses where failure of the controller or software could lead to lead to death or serious bodily injury of any person, or to severe physical or environmental damage.)

If the Leap Motion software does not appear to be producing data, stop the Leap Motion service or daemon and restart it. Unplug the Leap Motion device and plug it back in.

To restart the service on Windows, open up the list of Windows services by pressing Windows+R on your keyboard, typing in "Services.msc" in the text field, and pressing enter. From there, scroll down the list and look for "leap service". Once you find it, right click on it and start or restart it.

You can also restart the service by running the following commands in the command prompt in Administrator mode (instructions on how to do so can be found HERE ):

net stop LeapService

net start LeapService

On Mac, run the following commands:

sudo launchctl unload /Library/LaunchDaemons/com.leapmotion.leapd.plist

sudo launchctl load /Library/LaunchDaemons/com.leapmotion.leapd.plist

On Linux, leapd is still a user process.

To stop, press Ctrl+C if you are running interactively. If running in the background, useps -Ato find its process ID before terminating with thekillcommand.

To restart, just run leapd again.

Getting started guide

What are the minimum requirements?Make sure you are running the Leap Motion software or the Orion software

How do I set up the VR Developer Mount?Check out our developer portal for step-by-step instructions on attaching your VR Developer Mount and setting up a Leap Motion VR Application.

What can I do with the VR Developer Mount?After setting up the VR Developer Mount, get started with our VR resources for sample projects and to access the new API features.

Will the VR Developer Mount interfere with the Oculus Rift DK2s positional tracking camera?Mounting the device doesnt result in any issues with positional tracking to the best of our knowledge, since the DK2 actually has many more LEDs than necessary (which allows for experimental uses like this). Weve used it successfully without encountering any problems. The mount itself doesnt actually block any LEDs; occlusion only occurs when the Leap Motion Controller is in place.

Where can I buy the VR Developer Mount? The VR Mount can only be purchased through our online store. For countries wedon'tship to, we are currently exploring solutions. Updates will be provided here.

The Leap Motion Controller creates a three-dimensional interaction space of about 8 cubic feet above the device and a close range around an inch above the controller. Through a combination of hardware and software, it senses hands and fingers, as well as tools. This allows you to interact with your computer using precise motions without any visible delay.

More information can be found on our blog post HERE.

Here are a few simple ways to help make using the Leap Motion Controller feel natural and easy.

Do's:

Place the Leap Motion Controller on your desk where it's comfortable to use.

If standing or sitting high on a chair, DO hold your elbows near your side. Keep your forearms parallel to the floor and at a right-angle to your body.

If sitting at usual desk height, DO rest your elbows or forearms on your desk. Avoid uneven, sharp edges. Hold your hands just above the device, your wrist and hands in roughly a straight line.

HERE

Don'ts:

DON'T hunch over your device. Keep it's field of view clear from obstructions, including yourself.

DON'T bend your elbows and your wrists with your arms close together.

DON'T hold your arms straight ahead of you in the air.

DON'T rest your arms on a surface where it forces your elbows to be pointed out to the side.

VR:

For comfortable use with VR applications, review the Oculus health and safety guidelines .

The Leap Motion Controller is built on a unique mathematical model that maximizes speed and precision, so the raw data does not appear as a point cloud. Instead, at its most basic level, the API data arrives in frames. Because of this specialization, there are no depth images calculated anywhere at all.

The "point clouds" that were featured in our early videos are visualizations from some of our debugging tools. Becausethey'renot temporally or spatially consistent, they are not usable as methods of interaction. They also wouldnt work for non-hand type objects, which just end up looking like a jumbled mess.

That said, we're working on using the hardware in novel and exciting ways. We hope to make new data types available in future versions of our API.

Running the Leap Motion Diagnostics

You can run the set of diagnostic tests to help troubleshoot any problems you encounter when using your Leap Motion Controller.

To run the tests, open the Leap Motion Control Panel using the *Settings command in the menu attached to the Leap Motion icon shown in the menu bar (Mac) or task bar (Windows). Go to the Troubleshooting tab.

Before running the diagnostic tests, please make sure the Leap Motion Controller is connected to a USB2 or USB3 port on your computer. Avoid USB hubs or connecting the Leap Motion device to your computer through another USB peripheral (such as a keyboard).

Orion Users

The diagnostic tests have been updated in the Orion software and are running in the background. The status of these tests can be found in the Leap Motion Control Panel under the Troubleshooting tab.

Hardware and Software tests

The hardware and software tests verify that your Leap Motion Controller and the Leap Motion software are working correctly. If these tests fail, try the following remedies before re-running the diagnostic tests:

Check your USB connection. Ensure that you are not using a USB hub or connecting the Leap Motion device to your computer through another peripheral (such as a keyboard). We strongly recommend using the cable included with the Leap Motion Controller, if you are not already using it. Sometimes, connecting the controller to a different USB port can help.

Unplug the Leap Motion Controller and plug it back in.

Restart your computer.

Authentication

The Authentication test verifies that your Leap Motion Controller is genuine. The test can also fail if the firmware (the information stored on the device itself) has a problem. If this test fails, contact Leap Motion support.

Device Connectivity

The Device test verifies that the Leap Motion Controller can communicate with the Leap Motion software. If this test fails, check your USB connection. Unplug your Leap Motion Controller and then plug it back in. If the test still fails, try restarting your computer.

USB Bandwidth

The USB Bandwidth test verifies that your USB connection can transmit information fast enough. If this test fails, make sure that your are connecting the Leap Motion Controller directly to your computer with a quality cable. Try connecting to a different USB port on your computer. Disconnect other high-bandwidth USB or Bluetooth devices from your computer.

If the test still fails, turn on "Low Resource Mode" on the Troubleshooting tab of the Leap Motion Control Panel to reduce the USB bandwidth consumed by the Leap Motion Controller.

If you are connecting your Leap Motion Controller to a USB hub, please try directly connecting your controller to the computer as some hubs may cause issues with connectivity and performance.

Device Sensors

The Check Sensor test verifies that the signal quality of the Leap Motion sensor is adequate. If this test fails, please try the test again in a darker environment. If the test still fails, contact Leap Motion support.

Software

The Software test verifies that the Leap Motion software can properly analyze the scene in its field of view. If this test fails, make sure that you hold your hand over the device while running the test. If the test still fails, try restarting your computer.

Environmental Tests

The environmental tests look for external issues that may degrade performance of your Leap Motion Controller.

Window Smudge

The smudge test detects oil, grease or other foreign substance on the Leap Motion Controller sensor window. If this test fails, clean the sensor window with a clean, soft cloth such as you would use to clean eyeglasses.

Lighting Condition

The lighting check looks for overly bright infrared light sources in the Leap Motion Controller field of view.

The Leap Motion Controller achieves its best performance in an environment without any external infrared light sources. Because infrared light is invisible to the human eye, the source of the problem may not be immediately obvious.

If this test fails, try lowering window blinds or curtains, if daytime. Turn off or relocate halogen or nearby incandescent lights. (Energy efficient lights such as florescent bulbs should not cause interference.)

Note that the Leap Motion device will still work adequately under most poor lighting conditions. However, the tracking smoothness, range, and accuracy may suffer.

Calibration Test

The Calibration test verifies that the Leap Motion Controller is properly calibrated. Poor calibration can result in jumpy, erratic behavior in Leap-enabled applications. If this test fails, perform the calibration procedure using the Recalibrate Device button on the Troubleshooting tab of the Leap Motion Control Panel.
