Detailed finger data in Motive:Body?

[TobiasM]

Hello,
Currently we are running Motive 1.5 and are considering to upgrade to Motive Body.

Is it possible to track and record the detailed motion of each finger of one hand? We already have adhesive markers and a Flex 13 Camera setup. Until now we were only able to stream and record unlabled marker position, making it almost impossible creating hierarchic motion files.

Hello TobiasM,

Unfortunately, Motive 1.10 is still unable to capture the independent motion for each finger. Motive:Body does include a simple finger setup in which one marker is placed on the thumb, index and pinky. The rest of the finger motion is extrapolated from the three markers.

Unlabeled markers would still be the way to go if you are trying to place additional markers on the fingers. While Motive 1.10 does not contain any automated features to help with high resolution hand tracking, the labeling and editing tools have been improved and may be more useful for identifying the markers in Edit mode. Data quality has also been improved, and this may help to provide better hand data to work with.

Best,
Steven

Thanks for your reply steven.andrews!

Is it possible to lable markers which are not part of rigidbodies or skeletons in Motive 1.10? If this feature is supported, what happens if a marker is occluded by other objects? Does the marker loose its lable?

Greetings, TobiasM

Hi TobiasM,

My pleasure; we are happy to help!

It is possible to label markers that are not part of a rigid body or skeleton, but this cannot be done automatically or in realtime. The functionality for this is, currently, the same as it has been and requires the use of a MarkerSet while in Edit mode.
