ART

This guide delves into how to use the ART tracking system for absolute hand glove positioning.

Marker shape configuration

When tracking multiple objects in ART, it's advised to use the MANUS shape configurator.

Shape configuration

Marker locations are divided into 4 groups: Top, Bottom, Left and Right. Left and Right each have 5 columns (A, B, C, D and E). Left and Right each have 8-15 rows (1-8, 1-10, 1-12, 1-14, 1-15). Top and Bottom are always the same position, Left and Right differ between different sets. You will always need 4 markers in total.

Configuring Dtrack

In Dtrack the custom shapes need to be added one by one. Make sure no other optical markers are visible when calibrating.

Streaming

Set up DTrack so that it can stream to other applications. Please take note of the UDP port specified here for later.

MANUS Core Configuration

In MANUS Core Dashboard settings navigate down to Tracking Systems, set the ART port to whatever specified in DTrack (5000 by default) and enable the ART checkbox.

It's also advised to keep the keep tracker position setting On in the tracking subsection. ART trackers will default back to world zero when tracking is lost. This setting makes sure they stay in their last known position when tracking is temporarily lost.
