My hands tattoo causes Leap Motion to twitch, lose track, glitch, etc

DARKKi 2017-06-08 16:19:52 UTC #1

Like the topic says my other hands tattoo which is on my back side of my hand (picture at the bottom) usually when its visible it will glitch like hand repeatedly changes its orientation by 180degrees multiple times in second and sometimes loses track of it and when that is not happening by some miracle it then just glitches. So i cannot do anything with my left hand

Is there any fix for this or anything? I would like to get to use this product like it was advertised which is not track only one hand

Also i have noticed in several VR apps that when tracking one hand there is no problem but when another enters the screen then the refresh rate of hands go way down to 5-10fps. Anyone else has this and is there an fix to it?

Here is picture of my hand

Do you mind providing a screenshot of your hands in the visualizer so we can see what it looks like?

The orientation of your hands flipping may be due to the auto-orient tracking option in the Leap Motion Control Panel. You can try disabling it to see if that resolves the flipping.

Thanks!

Auto-orien tracking helped things a little bit but glitching still remains. I will record an video soon so you can see how it reacts to my hand. When i just have the hand still with back side of hand and tattoo visible the hand in visualizer jumps around, fingers move and stutters to every direction and usually it detects it as a new hand (isn't change in color that?) pretty frequently.

Yes, the change in color of a hand means that the hand gets reinitialized. Could you have someone with no tattoos test the sensor so we can check if it is indeed the tattoos causing issues?

A video of the issue occurring would also provide more information for us.

Thanks!

Well my other hand is working fine without the glitches.

I will try to do the video asap.

jhung 2017-06-12 15:08:43 UTC #6

Thanks DARKKi! Once you've provided the video, I will forward this thread to our engineering team to investigate.

DARKKi 2017-06-15 22:31:53 UTC #7

Okay finally got the video up

In the beginning i use my normal hand and then switch to one with the tattoo.

jhung 2017-06-15 22:50:50 UTC #8

Thanks for the video! I've forwarded this thread to our engineering team

DARKKi 2017-06-16 00:03:02 UTC #9

Thanks alot! I will be waiting for answer

I've heard back from our engineering team. Unfortunately, Tattooed hands are completely black in infrared. This will impact tracking, as the hand appears to have very different characteristics than a non-tattooed hand.

Our team is discussing some possible improvements to our tracking software to see if we can be more robust to in the future.

As a temporary workaround, you may be able to wear a cotton glove on your tattooed hand.

DARKKi 2017-06-16 19:38:14 UTC #11

Yeah, i think i will have to buy some thin glove or something then

And thanks for thinking about this issue, i think there are more users that have similar problems too (niche though)

Little OT question. In many games when just one hand is present tracking works fine but when other hand comes into picture hands "fps" drops to stuttering levels. Is there an fix for this or is this discussed somewhere?

jhung 2017-06-16 20:33:55 UTC #12

What are the specs of your machine? I don't think I've seen the fps drop once a second hand gets tracked. Does this occur in all apps or just the visualizer?

DARKKi 2017-06-16 22:19:54 UTC #13

AMD FX-8350 @ 4,6GHz
GeForce 1070 GTX OC'd
16GB Ram

It does not occur in visualizer it only occurs in apps.

jhung 2017-06-16 22:21:28 UTC #14

Your system pretty solid so I don't think that should be causing any issues. What apps does this occur in? Is it only some apps or all apps?

DARKKi 2017-09-30 09:49:01 UTC #15

Hi, sorry for late reply for some reason i did not get notification about this. It is still from all apps unfortunately

jhung 2017-10-02 15:08:38 UTC #16

Thanks for the additional information. I've forwarded it to our engineering team so we can work on improving this functionality.

DARKKi 2017-10-03 00:40:03 UTC #17

Okay, thanks a lot!

Hopefully i can enjoy Leap Motion fully in future :]

Hi,is Is it useful to put on gloves

erikdg 2019-04-22 12:37:17 UTC #19

Hi jhung,

I was wondering if a solution already has been found or at least the cause of the problem with the FPS drops.
I am also using the Leap Motion with the HTC Vive and I was running into the same problem as DARKKi with the FPS drops in a Unity app. I also seem to have almost exactly the same computer specs:
AMD FX-8350 @ 4,6GHz
GeForce 1070 GTX Ti
16GB Ram

Since a long time has passed you might have found more information about the problem. I'd like to hear about that.

Kind Regards!

@erikdg Can you start a new thread and let me know what version of the Leap Motion software and which application you're using where you encounter this?
