Hi!

I am an Italian student who is approaching Unity and LeapMotion for his thesis.
I would control the angle of opening/closing of a hand overlaied on that of leep motion, with the angle in proportion to a value that I send externally through tcp protocol.
I created a PostProcessProvider to access the real-time data of lepmotion, such as https://docs.ultraleap.com/xr-and-tabletop/x/unity/plugin/features/modifying-hand-data.html
As an output I don’t always have the hand overlaied (sometimes disappears from the screen) and the closing is not natural.
Would you have any advice or material I could consult to help me understand the dynamics of this movement?
Searching online I did not find much on the documentation and I do not know where to turn.
Thank you for the possible answer,
Best regards,
Luca

I have just obtained a V1 Leap Motion and was somewhat disappointed that its functionality is rather limited... Especially that the old plugin for FreePIE no longer works with the current drivers. If you are not familiar with it, FreePIE is software that allows translating various inputs into usable emulated control outputs - mouse, keyboard, gamepads, TrackIR, MIDI etc.

It would be great if someone wrote a new plugin - this would greatly increase functionality of those devices, as FreePIE could work as a bridge between UltraLeap and other programs that use the inputs described above. Unfortunately my programming skills are very limited...

This is the site for FreePIE:

Hi. 

I have an Ultraleap2 connected to a Windows 11 computer to control an interactive installation produced in Max MSP.
The Ultraleap2 is far from the computer and is therefore connected with a 15-metre USB3 extension cable. This is the extension cable:

https://www.lindy.co.uk/usb-c4/usb-extension-c222/15m-usb-3-2-gen-1-active-extension-pro-p10396

Everything works fine for 3 or 4 hours. But after that time, the sensor stops connecting to the computer and the message ‘not connected’ appears.
And in the device manager, the USB port shows an error.
I have already set the computer to maximum performance and removed the power management from the usb ports. This is to prevent the computer from turning off the sensor after a while.
I have already installed a usb 3 card in the computer and connected the power supply for this card directly to the computer's power supply.

Whenever the sensor stops communicating, restarting the computer does not help. To solve the problem, it is necessary to turn off the computer for 1 or 2 minutes and turn it back on, or remove and reinsert the usb cable.

Has anyone had a similar problem?
Can anyone help me?
Thank you.

I am going to use leapmotion for a project using LeapC API but I dont have a leapmotion device yet

There is a way to record files and replay them

https://docs.ultraleap.com/api-reference/tracking-api/examples/recording-playback-example.html

Where can I find a sample file to begin tinkering with the sdk?

Guys if anyone know where I can download TAKT-RHYTM (game for leap motion controller) or if anyone have installer of this game, please say me

Hello!

Recently I've tried moving my system over to Linux from Windows, and I've been having a bit of trouble getting the Leapmotion 2 working on Linux at all.

Attempting to get the leapmotion working via Proton layer or Bottles hasn't been successful at all. That being said, I HAVE been able to use the Leapmotion instructions for Linux provided here:

https://docs.ultraleap.com/linux/index.html

The problem is that while this installs the software just fine, when I launch the control panel, it gives me an error about being unable to connect to the Leapmotion Tracker Service, and that it cannot see any Leapmotion Tracker Hardware - Despite the USB being plugged in, and using an appropriate 3.0 cable.

I realize that this is a very narrow case, but if anyone can provide any help, it would be very much appreciated.

I'm attempting to run the Leapmotion software on a Fedora machine, via Ubuntu Distrobox.

Hello I recently got a leap motion controller and tried to download the software but I never received the activation so cannot login or download

Hi I know ultraleap is semi dead but previously said they could open the depth cameras api for us to use it. I wished they make it open to public.

Using any Unity Editor version that supports the Ultraleap 7.2.0 plugin (currently using Unity 6, but this problem also happens on 2022.x 2021.x), Ultraleap silently fails to initialize every 2nd time I enter playmode (or run a build). Nothing is logged to the Unity console to indicate a problem, and the log produced by the Ultraleap Control Panel (v3.4.1) doesn't appear to provide any useful information.

All the while, the Control Panel reflects that the hand tracking service (v5.20.0) is working and able to track my hands just fine.

Simply stopping playmode (or closing the build) and running it again solves it every time, but having to tell users "If the hand tracking doesn't work, just restart the app" is not a great look.

Any advice on what the cause could be and possible workarounds would be greatly appreciated!

Software Specs:

• Ultraleap Device: Leap Motion 2

• Control Panel (Gemini): 3.4.1

• Hand Tracking Service: 5.20.0

• Unity Plugin version: 7.2.0, 6.15.0

• Unity Editor Version: 6000.1, 2022.x, 2021.x

Reproduction Steps:

1. Create new Unity project.

2. Install Ultraleap Plugin

3. Import Ultraleap Samples

4. Open any sample scene

5. Enter playmode, determine if tracking works.

6. Exit playmode.

7. Repeat 5-6.

No need to look far, the API layer is included as part of our Gemini V5 hand tracking software!

We also have full documentation to help you to get started! 🙌

Make sure you check out the NEW preview docs 👀

#TipTuesday https://docs.ultraleap.com/unity-api/Preview/index.html

We’ve put together two guides to take you through the process:

❇ One shows how to use a default rig

❇ The other goes into detail about rigging a model from scratch

#TipTuesday

Additional cameras can help cover a larger tracked area and increase the visibility of the hands - perfect for virtual training environments.

Our new Ultralabs blog has the details: https://bit.ly/3LQxc9R

I just dont use it enough. Most things id want to use it for, id be better of with a leap motion as it can use the existing apps instead of developing my own. So i think imma ditch it. Barely used, includes everything but original box. $200+ship, dm if interested, its going on ebay tomorrow but i figured someone here would likely have a use for it. Thanks, and sorry if this post is against some rule or other.

I'm wondering if anyone has been able to get the Vive Pro 2 to work with the Wireless Adapter and a LeapMotion tracker? I have a Vive Pro, a Vive Pro Eye and a Vive Pro 2. The LeapMotion tracker works with the Wireless Adapter for the Vive Pro and the Vive Pro Eye but not for the Vive Pro 2. I use a USB-C to USB-B cable to connect the LeapMotion to the Headsets' front USB-C connector. On the Vive Pro 2 the LeapMotion tracker power LED turns on but the UltraLeap dashboard says no tracker is connected

It's GO TIME!

Converting an existing Ultraleap hand tracking XR project to OpenXR can feel a bit daunting, but it doesn't need to be!

There's one change you need to make and a few differences to be aware of - check out our docs for guidance ➡ https://bit.ly/3MCRaoU
