SimSA5_person_puts_down_object

Description:  A person sets down an object .  The two necessary tracks included in this event are (1) the person setting down the object and (2) the object(s) (e.g., purse). Tracks need not necessarily be the same length.  Multiple people carrying the same object will share the same event.  Set down activity only occurs if the item is separated from the individual (e.g. a person taking off gloves and placing them in their lap would not be a set down activity) and the object must be placed directly on a surface (not dropped or thrown). Occluded put down activities will only be annotated if the instant of the put down action ends is occluded for less than ½ second and the set down activity is definitive with conservative human interpretation. A person setting down multiple items at a time can be annotated as one event if the two items make contact with the new supporting surface within 1 second of each other.  Multiple people setting down a large item will constitute a single set down instance. For excluded and ambiguous included items, see Person Picks Up Object.

Start:  The event begins 1 s before the object makes contact with the new supporting surface (e.g., table).

End:  The event ends 1 s after the object has made contact with the new supporting surface.
