Abstract

There is provided a method of responding to a detected fall, the method comprising determining which one or two or more actions to perform in response to detecting a fall by a user based on a user profile and/or user preference and/or the context of the detected fall; and performing the determined action.

Claims

1. A method of responding to a detected fall, the method comprising:

determining which one of two or more actions to perform in response to detecting a fall by a user based on a user profile and/or user preference and/or the context of the detected fall; and

performing the determined action.

2. The method as claimed in claim 1, wherein the two or more actions comprise two or more of:

ignoring the detected fall, requesting help for the user, initiating a call, waiting for the expiry of a revocation period before requesting help for the user or initiating a call, and checking a status of the user after another revocation period.

3. The method as claimed in claim 1, wherein the user profile comprises information on whether the user lives alone, the fall risk of the user and/or the fall history of the user.

4. The method as claimed in claim 1, wherein the user preference comprises an indication of the length of a revocation period after the detection of the fall before help is requested for the user or a call is initiated.

5. The method as claimed in claim 1, wherein the context of the detected fall comprises an indication of when the detected fall occurred, the location of the user when the detected fall occurred, the environmental temperature, the magnitude of a detected impact and/or the direction that the user fell.

6. The method as claimed in claim 1, wherein the step of determining further comprises determining which one of two or more actions to perform based on a status of the user following the fall.

7. The method as claimed in claim 6, wherein the status of the user comprises an amount of movement by the user following the detected fall, an indication of whether the user has stood up following the detected fall and/or measurements of physiological characteristics.

8. The method as claimed in claim 1, wherein the context of the fall indicates whether the fall has occurred indoors or outdoors, and the step of determining comprises:

determining whether the detected fall has occurred indoors or outdoors;

determining that help should be requested for the user or a call initiated if the detected fall is determined to have occurred outdoors; and

determining that a revocation period should expire before help is requested for the user or a call initiated if the detected fall is determined to have occurred indoors.

9. The method as claimed in claim 1, wherein the context of the fall indicates the temperature in the environment in which the detected fall has occurred, and the step of determining comprises:

determining whether the temperature in the environment in which the detected fall has occurred is below a threshold;

determining that help should be requested for the user or a call initiated if the temperature in the environment is below the threshold; and

determining that a revocation period should expire before help is requested for the user or a call initiated if the temperature in the environment is above the threshold.

10. The method as claimed in claim 1, wherein the step of determining comprises:

determining whether the user lives alone from a user profile;

determining that help should be requested for the user or a call initiated if the user lives alone; and

determining that a revocation period should expire before help is requested for the user or a call initiated if the user does not live alone.

11. A computer program product having computer readable code embodied therein, the computer readable code being configured such that, on execution by a processing unit, the processing unit performs the method of claim 1.

13. The apparatus as claimed in claim 11, wherein the two or more actions comprise two or more of:

ignoring the detected fall, requesting help for the user, initiating a call, waiting for the expiry of a revocation period before requesting help for the user or initiating a call, and checking a status of the user after another revocation period.

12. An apparatus for providing a response to a detected fall, the apparatus comprising:

a processing unit configured to;

determine which one of two or more actions to perform in response to detecting a fall by a user based on a user profile and/or user preference and/or the context of the detected fall; and

perform the determined action.

14. The apparatus as claimed in claim 12, wherein the processing unit is configured to obtain the user profile and/or user preference from a memory.

15. The apparatus as claimed in claim 12, wherein the processing unit is configured to obtain information on the context of the detected fall from one or more sensors.
