Presented herein are systems and methods for detecting that a human or other object is on-the-floor, e.g., after a fall or other means of descent to the floor. The disclosed technology does not require a historic trajectory of movement, nor does the disclosed technology require a worn device. Detection is performed by determining the configuration of the subject using environmental data, such as visual data or depth data. 1. A method of detecting that an object is on-the-floor , without the need for a worn sensor , 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;automatically identifying within the environmental data, by the processor, a configuration of each of the one or more objects; andautomatically determining, by the processor, an on-the-floor status for each of the one or more objects.2. The method of claim 1 , wherein the environmental data is one or more of visual data claim 1 , spatial data claim 1 , temperature data claim 1 , depth data.3. The method of claim 1 , wherein the automatically identifying one or more objects utilizes one or more of machine learning claim 1 , deep learning claim 1 , pattern recognition claim 1 , neural network.4. The method of claim 1 , wherein the object is one or more of human claim 1 , animal claim 1 , and an inanimate object.5. The method of claim 1 , wherein the each configuration is determined by one or more of center-of-mass claim 1 , pose claim 1 , aspect ratio claim 1 , locations of joints.6. The method of claim 1 , wherein the on-the-floor status is determined claim 1 , at least in part claim 1 , by a duration of proximity by the object near the floor.7. The method of claim 1 , wherein a non-floor surface (e.g. claim 1 , such as a couch) is used rather than a floor surface.8. The method of claim 1 , wherein personal or private data are removed from the environmental data.9. The ...
