Abstract

A biometric monitoring device measuring various biometric information is provided that allows the person to take and/or display a heart rate reading by a simple user interaction with the device, e.g., by simply touching a heart rate sensor surface area or moving the device in a defined motion pattern. Some embodiments of this disclosure provide biometric monitoring devices that allow a person to get a quick heart rate reading without removing the device or interrupting their other activities. Some embodiments provide heart rate monitoring with other desirable features such as feedback on data acquisition status.

Claims

1. An apparatus comprising:

one or more biometric sensors comprising a heart rate sensor;

an activator of the heart rate sensor;

a heart rate sensor surface area through which the heart rate sensor can collect heart rate data from a user;

an activator surface area through which the activator can receive activation signals from the user;

at least one processor; and

a memory,

wherein;

the one or more biometric sensors, the activator, the at least one processor, and the memory are communicatively connected, and

the memory stores computer-executable instructions for controlling the at least one processor to cause the heart rate sensor to;

start collecting heart rate data through the heart rate sensor surface area in response to the activator receiving an activation signal through the activator surface area caused by a single user-gesture; and

cause the heart rate sensor to automatically stop collecting heart rate data after a defined criterion is met and remain in a state that does not collect heart rate data until another activation signal caused by a new user-gesture is received without requiring further user-gestures in addition to the single user-gesture.

2. The apparatus of claim 1, wherein the defined criterion is a defined period of time for heart rate data collection or a defined quality of heart rate reading.

3. An apparatus comprising:

one or more biometric sensors comprising an optical heart rate sensor;

an activator of the optical heart rate sensor;

a heart rate sensor surface area through which the heart rate sensor can collect heart rate data from a user;

an activator surface area through which the activator can receive activation signals from the user;

a feedback mechanism;

at least one processor; and

a memory,

wherein;

the optical heart rate sensor, the activator, the at least one processor, and the memory are communicatively connected, and the memory stores computer-executable instructions for controlling the at least one processor to;

cause the optical heart rate sensor to start collecting heart rate data through the heart rate sensor surface area in response to the activator receiving an activation signal through the activator surface area caused by a single user-gesture, and

provide user feedback, through the feedback mechanism, with reference to the collected heart rate data without requiring further user-gestures in addition to the single user-gesture.

4. The apparatus of claim 3, further comprising an altimeter communicatively connected with the heart rate sensor, the activator, the at least one processor, and the memory, wherein the memory further stores computer-executable instructions for controlling the at least one processor to obtain altitude data from the altimeter.

5. The apparatus of claim 3, wherein the heart rate sensor only collects data when the single user-gesture is occurring and only from a body part of the user used to provide the single user-gesture.

6. The apparatus of claim 5, wherein the heart rate sensor surface area and the activator surface area are arranged on a substantially flat plane, thereby allowing a single body part of a user to simultaneously interact with the activator and the heart rate sensor.

7. The apparatus of claim 3, wherein the memory further stores computer-executable instructions for controlling the at least one processor to cause the heart rate sensor to stop collecting heart rate data after a defined criterion is met without requiring further user gestures in addition to the single user-gesture.

8. The apparatus of claim 3, wherein the apparatus further comprises a vibration motor and the feedback to the user is provided as haptic vibration.

9. The apparatus of claim 3, further comprising a housing that houses at least the heart rate sensor and the activator, wherein the heart rate sensor surface area and the activator surface area are less than 1 centimeter apart as measured by the distance along the exterior surface of the housing, thereby allowing a single body part of a user to simultaneously interact with the activator and the heart rate sensor.

10. The apparatus of claim 9, wherein the heart rate sensor surface area and the activator surface area are less than 0.5 centimeters apart as measured by the distance along the exterior surface of the housing.

11. The apparatus of claim 9, wherein the heart rate sensor surface area and the activator surface area overlap along the exterior surface of the housing.

12. The apparatus of claim 9, wherein the heart rate sensor surface area is a seamless portion of the surface of the housing.

13. The apparatus of claim 9, wherein the activator surface area is a seamless portion of the surface of the housing.

14. The apparatus of claim 3, wherein the apparatus has only one heart rate sensor surface area.

15. The apparatus of claim 3, wherein the heart rate sensor surface area and the activator surface area form one continuous surface area.

16. The apparatus of claim 3, wherein the activator of the heart rate sensor is a proximity sensor.

17. The apparatus of claim 16, wherein the single user-gesture consists of the user bringing a body part into proximity with the activator surface area.

18. The apparatus of claim 3, wherein the single user-gesture consists of a touch of the activator surface area with a single body part.

19. The apparatus of claim 3, wherein the apparatus is configured to be removably attachable to a wearable accessory, and the activator surface area and heart rate sensor surface area are configured to be accessible for user interaction when attached to the wearable accessory.

20. The apparatus of claim 3, wherein the heart rate sensor, the activator, the at least one processor, and the memory are communicatively connected to a user interface on the apparatus.

21. The apparatus of claim 3, wherein the heart rate sensor, the activator, the at least one processor, and the memory are communicatively connected to a user interface on a linked smartphone, tablet, or computer.

22. The apparatus of claim 21, wherein the user interface comprises one or more of the following:

the heart rate sensor surface area, the activator surface area, a touch screen, a display, an LED, a button, an accelerometer, a gyroscope, a finger print reader, a vibration motor, a proximity sensor, and a speaker.

23. A method for monitoring heart rate using a biometric monitoring device, comprising:

receiving, by an activator, an activation signal representing a single user-gesture by a user;

activating a heart rate sensor, in response to the activation signal, to start collecting heart rate data from the user;
