Systems and methods for predictive environmental fall risk identification

1. A method for predictive environmental fall risk identification for a user, the method comprising:

receiving dynamic observations of an environmental map using a sensor;

determining the environmental map;

collecting a set of risk factors for the environmental map using the sensor;

assessing the set of risk factors for the environmental map for a user;

creating a first training set comprising the collected set of risk factors;

training an artificial neural network in a first stage using the first training set;

creating a second training set for a second stage of training comprising the first training set and the dynamic observations of the environmental map;

training the artificial neural network in the second stage using the second training set;

predicting a fall risk of the user using the artificial neural network; and

sending an alert to the user based on the dynamic observations of the environmental map and the fall risk of the user.

2. The method recited in claim 1 , further comprising:

identifying commonly occurring hazards that may cause a fall including one or more of poor lighting in a stairwell and water spills on tile floors.

3. The method recited in claim 1 , further comprising:

optimizing placement of the sensor, the optimizing of placement of the sensor including maximizing coverage to identify and detect both newly formed risks and time remained in a room by the user.

4. The method recited in claim 1 , wherein the assessing the set of risk factors for the environmental map for the user comprises risks associated with different rooms in the environmental map, risks associated with different rooms in the environmental map being better defined using machine-learning to yield predictive identifiers.

5. The method recited in claim 1 , wherein the sensor is a visual sensor.

6. The method recited in claim 1 , wherein the sensor is a radio frequency sensor.

7. The method recited in claim 1 , wherein the sensor is an audio sensor.

8. The method recited in claim 1 , wherein the sensor is a light detection and ranging sensor.

9. The method recited in claim 1 , wherein the fall risk of the user increases when the user travels from a carpet floor to a tile floor.

10. The method recited in claim 1 , wherein the fall risk of the user increases when the user travels from a rug floor to a carpet floor.

11. A system for predictive environmental fall risk identification for a user, the system comprising:

a sensor, the sensor providing dynamic observations of an environmental map;

at least one processor; and

a memory storing processor-executable instructions, wherein the at least one processor is configured to implement the following operations upon executing the processor-executable instructions:

determining the environmental map;

collecting a set of risk factors for the environmental map using the sensor;

assessing the set of risk factors for the environmental map for the user;

creating a first training set comprising the collected set of risk factors;

training an artificial neural network in a first stage using the first training set;

creating a second training set for a second stage of training comprising the first training set and the dynamic observations of the environmental map;

training the artificial neural network in the second stage using the second training set;

predicting a fall risk of the user using the artificial neural network; and

sending an alert to the user based on the dynamic observations of the environmental map and the fall risk of the user.

13. The system of claim 11 , further comprising the processor-executable instructions including optimizing placement of the sensor, the optimizing of placement of the sensor including maximizing coverage to identify and detect both newly formed risks and time remained in a room by the user.

14. The system of claim 11 , further comprising the processor-executable instructions including wherein the assessing the set of risk factors for the environmental map for the user comprises risks associated with different rooms in the environmental map, risks associated with different rooms in the environmental map being better defined using machine-learning to yield predictive identifiers.

15. The system of claim 11 , wherein the sensor is a visual sensor.

16. The system of claim 11 , wherein the sensor is a radio frequency sensor.

17. The system of claim 11 , wherein the sensor is an audio sensor.
