Hand tracking is a feature of the F200 and SR300 cameras. The R200 instead has Person Tracking. You can get Java code for the features of the Person Tracking system at this documentation link.

"Blob tracking" of the hand - following the general shape of the hand palm instead of a bone joint - may also be an option for you.

Somebody else encountered this error too.

https://software.intel.com/en-us/forums/realsense/topic/645536# comment-1880348 Skeleton Tracking Not Working

No answer was given on that post, sadly. Also, other people trying to use skeleton tracking on the R200 always had the number of joints returned as '0'. There is some useful information in this link though.

I and a member of the Intel support staff (Peter) were involved in helping on that question. But a solution was never found. Maybe somebody will have a new idea now about how to fix it.

I've already seen that question.

i think that there seems to be little support for Java

It has the java code in the document, but it is not in the java library.

I suggest that Intel should update the libpxcclr.java.jar as soon as possible for java developers

Thank you for your reply,MartyG

A few days ago, Intel announced that it was no longer going to continue development and marketing of RealSense's web component due to a security vulnerability. My understanding from reading the information is that they are not removing the component from the 2016 R2 and R3 SDK versions but will not be supporting it in future SDKs.

This would seem to throw into doubt future updating of RealSense's JavaScript and Java components.

Hi HyunjiRa,

Some user that I worked with in the past told me that he was able to get Skeleton Tracking by setting tracking mode to 'interactive', however, only 6 points are exposed in the SDK R2 (the last SDK that supports the R200 cameras and Java) and correspond to the upper body, note that this was done using C# . This feature is in Preview mode and so its functionality is limited. Still, you might want to give it try changing the tracking mode.

Regards,

Hi HyunjiRa

Do you have any updates on this case?
