 ===== Usage =====
-The following queries read data from a semantic map and visualize it in the browser-based visualization.
+First, setup the rosbridge communication interface and initialiaze the `knowrob_vis` package.
   $ roslaunch rosbridge_server rosbridge_websocket.launch
   $ rosrun rosprolog  rosprolog knowrob_vis
+Markers must be explicitly published by the user with following query ([[http://www.open-ease.org/|openEASE]] does this automatically).
+  % publish modified marker
+  ?- marker_publish.
+==== Semantic Map Marker ====
+The following queries read data from a semantic map and visualize it in the browser-based visualization.
   % load and visualize semantic map
   ?- owl_parse('package://knowrob_map_data/owl/ccrl2_semantic_map.owl').

+==== Agent Marker ====
-  ?- marker_publish.
+The following queries read data from a robot description, look up the robot pose in the mongo DB
+and visualize it in the browser-based visualization.
+  % load and visualize the pr2 robot for given timepoint T
+  ?- owl_parse('package://knowrob_srdl/owl/PR2.owl').
+  ?- mng_robot_pose_at_time(pr2:'PR2Robot1','/map',T,_), marker_update(object(pr2:'PR2Robot1'),End).
+==== Trajectory Marker ====
+The following queries read data from a robot description, sample the '/base_link' between T0 and T1
+and visualize it in the browser-based visualization.
+  % load and visualize the base link of the pr2 robot for given timerange (T0,T1)
+  ?- owl_parse('package://knowrob_srdl/owl/PR2.owl').
+  ?- marker_update(trajectory('/base_link'), interval(T0,T1,dt(Interval))).
