SimSA5_person_picks_up_object

Description:  A person picking up an object.  The two necessary tracks included in this event are (1) the person picking up the object and (2) the object(s) (e.g., bag). Tracks need not necessarily be the same length. A person picking up multiple items at a time can be annotated as one event if the two items break contact with the surface within 1 second of each other.  Occluded pick up activities will only be annotated if the instant the pick up action begins is occluded for less than ½ second and the pickup activity is definitive with reasonable human interpretation.  Moving or adjusting an object without vertical motion breaking contact with the resting surface does not include a “pick up” activity.  An item must be at least the size of a coffee cup to trigger a pickup activity and not be on the excluded list.  Multiple people picking up a large item will constitute a single pick up instance.

This activity excludes any activities which satisfy the object transfer definition.

Excluded List (do NOT annotate the activity “person picks up object” when only the following objects are involved):  Phones, Pens/Pencils/Markers, Individual Sheets of Paper, Money, Hat, Gloves, Apple (or similarly sized food items)

Included List (DO annotate  the activity “person picks up object” when the following objects are involved): Examples, which are not exhaustive, include newspaper, Frisbee, Soccer balls, cups, another person, or occluded items that can be seen in the individual’s hand after half a second.

Start:  The event begins the moment the object breaks contact with the previous supporting surface (e.g., table).

End:  The event ends 1 second after the object is released or no longer active in motion associated with pick up (e.g., standing up right).  If the person holding the object begins to walk, then the event ends after 1 s of walking (or next subsequent activity).
