1. A method of detecting that an object is on-the-floor, the method comprising:
receiving, by a processor of a computing device, environmental data;
automatically identifying within the environmental data, by the processor, one or more objects and a surface;
automatically identifying within the environmental data, by the processor, a configuration of each of the one or more objects, wherein the configuration comprises a center-of-mass; and
automatically determining, by the processor, an on-the-floor status for each of the one or more objects,
wherein, for each of the one or more objects, the determining of the on-the-floor status comprises determining whether the center-of-mass of the object is located within a threshold distance to the surface,
wherein the method occurs without using a sensor worn by the object and without using a historic trajectory of movement of the object.
