Abstract

A personal assistance monitor for estimating whether a person needs assistance or not, and for requesting assistance, when appropriate. Some embodiments of the present invention can request help for a person even if the person is unconscious or paralyzed. The illustrative embodiment comprises two bracelets—one is worn on a person'"'"'s right wrist and the other is worn on the left wrist. Each bracelet comprises an acceleration sensor that detects the acceleration of the wrist to which it is affixed. The measures of motion detected by both bracelets are analyzed for insight into the person'"'"'s well-being. When the illustrative embodiment estimates that the person needs assistance, the illustrative embodiment prompts the person to decline assistance. When the person declines assistance, the illustrative embodiment continues monitoring the person. In contrast, when the person fails to decline the offer of assistance, the illustrative embodiment requests help.

Claims

1. A method comprising:

receiving, from a motion sensor, a measure of motion of a location on a person'"'"'s body;

generating, by a processor, a motion profile based on the measure of motion;

when the motion profile exhibits a periodic pattern of distress, generating, with a first output device, a prompt for the person to decline assistance; and

when the person fails to decline assistance, transmitting, with a second output device, a request for assistance for the person.

2. The method of claim 1 wherein the first output device is a tactile vibrator.

3. The method of claim 1 wherein the periodic pattern of distress is tremors.

4. The method of claim 1 wherein the periodic pattern of distress is shuddering.

5. A method comprising:

receiving, from a motion sensor, a first measure of motion of a location on a person'"'"'s body;

generating, by a processor, a motion profile based on the first measure of motion;

when the motion profile exhibits a sign of distress, generating, with a first output device, a prompt for the person to decline assistance;

receiving, from the motion sensor, a second measure of motion;

generating an estimate of whether the person has declined assistance based on the second measure of motion; and

when the estimate of whether the person has declined assistance indicates that the person has failed to decline assistance, transmitting, with a second output device, a request for assistance for the person.

6. The method of claim 5 wherein the first output device is a tactile vibrator.

7. The method of claim 5 wherein the sign of distress is a pattern of distress.

8. The method of claim 7 wherein the pattern of distress is periodic.

9. A method comprising:

receiving, from a motion sensor, a first measure of motion of a location on a person'"'"'s body;

generating, by a processor, a first motion profile based on the first measure of motion;

when the first motion profile exhibits a first sign of distress as characterized by a parameter, generating, with a first output device, a prompt for the person to decline assistance;

when the person declines assistance, modifying the parameter to generate a modified parameter;

receiving, from the motion sensor, a second measure of motion of the location on the person'"'"'s body;

generating a second motion profile based on the second measure of motion; and

when the second motion profile exhibits a second sign of distress as characterized by the modified parameter, transmitting, with a second output device, a request for assistance for the person.

10. The method of claim 9 wherein the first output device is a tactile vibrator.

11. The method of claim 9 wherein the first sign of distress is a pattern of distress.

12. The method of claim 11 wherein the pattern of distress is periodic.

13. A method comprising:

receiving, from a motion sensor, a measure of motion of a location on a person'"'"'s body;

generating, by a processor, an estimate of well-being based on the measure of motion;

when the estimate of well-being fails to reach a threshold of well-being, generating, with a first output device, a prompt for the person to decline assistance; and

when the person fails to decline assistance, transmitting, with a second output device, a request for assistance for the person.

14. The method of claim 13 wherein the first output device is a tactile vibrator.

15. The method of claim 13 further comprising:

receiving an estimate of the location of the person; and

wherein the estimate of well-being is also based on the estimate of the location of the person.

16. The method of claim 13 further comprising:

receiving a measure of ambient light level in the vicinity of the person; and

wherein the estimate of well-being is also based on the measure of ambient light level.

17. The method of claim 13 further comprising:
