Abstract
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.
Claims20
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.
4 more elements
A system for detecting on-the-floor status of an object, the system comprising:
- an ambient sensor;
- a processor;
- and
- a memory storing instructions thereon, wherein the instructions, when executed by the processor, cause the processor to:
- receive environmental data;
- automatically identify one or more objects and a surface within the environment;
- automatically identify a configuration for each object, wherein the configuration comprises a center-of-mass;
- and
- automatically determine 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 instructions do not use a sensor worn by the object or a historic trajectory of movement of the object.
