V2 Software: New SDK + Consumer Update, v2.1.5+22693

[mbright]

Hi everyone,

I’m excited to announce a new V2 tracking software update which is available to consumers, at www.leapmotion.com/setup, as well as for developers, at http://developer.leapmotion.com!

What’s New

• Image pass-through is improved in robust mode
• Lower latency for two-hand tracking
• Bug fixes for HP embedded devices
• Fix of rare service hang issue
• Image API is now available in Objective-C
• Optimize HMD option added to LeapJS v0.6.3
• fingers.extended() and fingerType() no longer modify the original lists
• Various bug fixes and performance improvements

Known Issues (General)

• In some situations when it appears the Leap Service is not running, it is stuck in a loop consuming a full core's CPU. When this happens, simply restart the service.
• Applications built with SDK 2.1.0 or 2.1.1 must update DLLs to 2.1.2 or higher to improve performance
• Avast! Antivirus can interfere with service installation (disable shields to work around)
• Secure WebSocket (TLS) isn't supported for Firefox/Chrome on Linux or in Firefox on Mac/Windows
• Linux Chrome version 36 requires setting "Allow insecure WebSocket from https origin" under chrome://flags
• Chrome on Windows 7 sometimes fails to respond to emulated touch points – to fix this, click inside the program with a mouse
• JavaScript client library do not support setting gesture parameters
• The sphereRadius and sphereCenter functions of the Hand class are unstable when the hand is fully open
• Tracking quality is lower when making a fist or with one finger extended
• Tracking may not work as well with bracelets, rings, watches, sleeves, etc.
• A tap gesture will register when a small circle gesture is made
• CPU usage and latency is not yet optimized for skeletal tracking
• Linux does not support background apps or onFocus callbacks

Known Issues (VR)

• Applications using Image API must link with updated DLLs.
• The latest version of the Oculus firmware limits bandwidth for the DK2’s built-in USB port, which harms the controller’s performance. For now, we * recommend using the free cable extender bundled with the mount to connect the controller directly to the computer.
• Tracking performance may degrade when closely facing large reflective surfaces like white walls. (This is a broader issue with V2 tracking that we’re constantly improving on.)
• Tracking degrades when arms are held directly away from the body (i.e. elbows straight).
• Some poses are not currently tracked reliably in head-mounted display (HMD) mode (e.g. pinch/rotate, 3- and 4-finger poses).
• Minimized or out-of-focus applications using the HMD policy flag can affect the service state. Close such programs before switching back to non-VR apps.

As always, we greatly appreciate your feedback on the build, especially as we continue to enhance head-mounted beta tracking.

Cheers!

Quick question, I cannot seem to find the SDK folder for the OSX download, was it placed in some directory when the .dmg installer ran or was it not included?

Thanks!

[DanPeterson]

If you grabbed the file from leapmotion.com/setup that does not include the SDK

To get the installer and SDK together, please visit http://developer.leapmotion.com/

Heya @DanPeterson I'm running into the same issue as @ciccio99 - I am downloading from developer.leapmotion but what I get for OSX is a dmg with a pkg installer only --- SDK not found.

[Joe_Ward]

@leomurillo, @ciccio99 The OS X download with SDK is now available. Sorry for the inconvenience.

[leomurillo]

All good now, thanks @Joe_Ward!

Ever since I updated to 2.1.5 the Leap won't work with the .exe of my Unity project. Debug it works fine, but when I build the .exe (exactly the same scene) the Leap won't register at all like it doesn't exist.

Any ideas on what could have caused this? I have never had this problem before, and it started after the update.

Note: I have updated my DLLs to the latest versions.

Just in case anyone ever has this problem I fixed it by changing Architecture from x86_64 to x86 in Build Settings.

@Palindrome

If you want to build for x86_64, I think it works to copy LeapSDK\lib\x64\Leap.dll and LeapCSharp.dll into Assets\Plugins\x86_64\

We had originally tested the Unity 'plugin' only with 32-bit, but it's probably about time we distributed both in the UnityAssets folder in the SDK.

Hello, does anybody found that v2.1.5+22699 is less stable than before? Sometimes I just put my hand upon the leap motion and stretch my index finger. I keep this gesture static but there is always some tremble of the finger in the model. I don't know if this is only the problem of my controller or it is a common one. Thanks.

Hi,
Don't know whether its right place to ask.
I have borrowed Leap Motion from my friend but forgot to take the cable. So i tried with normal cable that fits only in one slot of Leap Motion.
So my question is Whether the range of Leap motion changes as you change the cable or is it the same..?
Because i can detect the hands only around 1 feet but not more than that as said the range is 1 inch to 2 feet. Any help is appreciated.
