Systems and methods for providing biofeedback information to a cellular telephone and for using such information

1. A system comprising:

a plurality of wearable bands including at least two wrist bands, the wearable bands each including one or more accelerometers, one or more proximity sensors for determining distance to other wearable bands, an identification indicia, and a communications device; and

a mobile device adapted to communicate with one or more of the plurality of wearable bands and to determine an exercise being performed by a wearer of the plurality of wearable bands based on information transmitted by the wearable bands;

wherein the mobile device includes a cellular telephone,

wherein the information transmitted by the wearable bands indicates a relative position and motion of user appendages upon which the wearable bands are worn,

wherein the relative position and motion of the user appendages are computed based upon relative position and motion of the wearable bands determined by tracking changes in the position, movement, and orientation over time of the wearable bands using the accelerometers and proximity sensors, and

wherein the exercise determined by the mobile device is used to play a video game running on the mobile device.

2. The system of claim 1 wherein the mobile device includes an authentication module and one or more game modules.

3. The system of claim 2 wherein the authentication module is operative to aggregate information transmitted by the wearable bands and provide authenticated activity information to the one or more game modules.

4. The system of claim 3 wherein the authentication module includes a database of activities, and

wherein the authentication module is operative to match aggregated information transmitted by the wearable bands to one or more activities in the database of activities and to select a best match from among the matched one or more activities.

5. A method comprising:

sensing a plurality of biometric information of a user;

transmitting the biometric information from wearable bands including at least two wrist bands worn by the user to a mobile device, the wearable bands each including one or more accelerometers, one or more proximity sensors for determining distance to other wearable bands, an identification indicia, and a communications device;

receiving the transmitted information in the mobile device, the mobile device including a cellular telephone;

determining a physical exercise associated with the information; and

providing a signal indicative of an authentication that the physical exercise has been performed by the user to a game application running on the mobile device,

wherein the biometric information indicates a relative position and motion of user appendages upon which the wearable bands are worn,

wherein the relative position and motion of the user appendages are computed based upon relative position and motion of the wearable bands determined by tracking changes in the position, movement, and orientation over time of the wearable bands using the accelerometers and proximity sensors, and

wherein the physical exercise determined by the mobile device is used to play the game application running on the mobile device.

6. The method of claim 5 wherein determining a physical exercise associated with the information includes:

aggregating the information; and

comparing the aggregated information to a database of activities.

7. The method of claim 6 wherein determining a physical exercise associated with the information further includes finding a best match between the aggregated information and stored patterns of information each associated with an activity in the database of activities.

8. A method comprising:

sensing a plurality of biometric information regarding a user indicative of a relative position and movement of both arms of the user, wherein wearable bands, one worn on each wrist, are used to sense at least some of the biometric information using one or more accelerometers;

transmitting the biometric information from the wearable bands to a mobile device that includes a cellular telephone;

receiving the transmitted biometric information in the mobile device;

determining a physical exercise associated with the biometric information; and

providing a signal indicative of an authentication that the physical exercise has been performed by the user to a game application running on the mobile device,

wherein the biometric information indicates a relative position and motion of user appendages upon which the bands are worn,

wherein the relative position and motion of the user appendages are computed based upon relative position and motion of the wearable bands determined by tracking changes in the position, movement, and orientation over time of the wearable bands using the accelerometers, and

wherein the physical exercise determined by the mobile device is used to play the game application running on the mobile device.

9. The method of claim 8 wherein determining a physical exercise associated with the biometric information includes:

aggregating the biometric information; and

comparing the aggregated information to a database of activities.

10. The method of claim 8 wherein determining a physical exercise associated with the biometric information further includes finding a best match between the aggregated information and stored patterns of information each associated with an activity in the database of activities.

11. The method of claim 8 wherein the wearable bands are used to sense at least some of the biometric information using one or more proximity sensors, and

wherein relative position and motion of the wearable bands are determined by tracking changes in the position, movement, and orientation over time of the wearable bands using the accelerometers and proximity sensors.
