Wirelessly identifying participant characteristics
A system and method for identifying persons near a mobile device includes a wireless signaling system including an incoming wireless signal receiver, a device motion sensing system including at least a first sensor and a controller configured to determine whether the device is being moved in accordance with a predetermined gesture and to responsively enter a personnel data collection mode. In the personnel data collection mode, the device may transmit a query and receives an identification signal from at least one other device and identifies a user of the device based on the received identification signal. The predetermined gesture is a spinning gesture in an embodiment. In an embodiment, a thermal sensor is used to identify or enumerate personnel. The identification signal may be one of a Bluetooth ID and a WiFi ID.
1. A mobile device capable of identifying persons near the mobile device comprising:
a wireless signaling system including an incoming wireless signal receiver;
a device motion sensing system including at least a first sensor; and
a controller configured to determine, based on a signal generated by the first sensor, whether the device is being moved in accordance with a predetermined gesture and entering a personnel data collection mode, if it is determined that the device is being moved in accordance with a predetermined gesture, whereby the device receives an identification signal at the incoming wireless signal receiver from at least one other device and generates a personnel identification based on the received identification signal.
2. The mobile device in accordance with claim 1 , wherein the wireless signaling system further comprises an outgoing wireless signal transmitter and wherein the controller is further configured to query the at least one other device via the outgoing wireless signal transmitter prior to receiving the identification signal at from at least one other device.
3. The mobile device in accordance with claim 1 , wherein the predetermined gesture is a spinning gesture.
4. The mobile device in accordance with claim 1 , wherein the first sensor is an inertial sensor.
5. The mobile device in accordance with claim 1 , wherein the first sensor is a magnetometer.
6. The mobile device in accordance with claim 1 , wherein the first sensor is a gyroscope.
7. The mobile device in accordance with claim 1 , wherein the device motion sensing system further includes a second sensor, and wherein the first sensor and the second sensor are selected from the group consisting of an accelerometer, a gyroscope, a gravitometer and a magnetometer.
8. The mobile device in accordance with claim 1 further comprising at least one thermal sensor, wherein the controller is further configured to use the at least one thermal sensor to generate a personnel identification.
9. The mobile device in accordance with claim 1 further comprising at least one thermal sensor, wherein the controller is further configured to use the at least one thermal sensor to count personnel.
10. The mobile device in accordance with claim 1 , wherein the incoming wireless signal receiver includes a thermal sensor.
11. The mobile device in accordance with claim 1 , wherein the incoming wireless signal receiver includes a radio frequency (RF) receiver.
12. The mobile device in accordance with claim 2 , wherein the outgoing wireless signal transmitter has a type selected from the group consisting of infrared and RF.
13. The mobile device in accordance with claim 1 , wherein the identification signal is one of a Bluetooth ID and a WiFi ID.
14. A method of identifying personnel around a mobile device comprising:
detecting a predetermined gesture with respect to the mobile device;
based on detecting the predetermined gesture, entering a personnel data collection mode;
while in the personnel data collection mode, receiving an identification signal from another device within short range communication distance of the mobile device, the other device being associated with a user; and
generating an identification of the user at the mobile device based on the received identification signal.
15. The method in accordance with claim 14 , wherein the wireless signaling system further comprises an outgoing wireless signal transmitter and wherein the controller is further configured to query the at least one other device via the outgoing wireless signal transmitter prior to receiving the identification signal at from at least one other device.
16. The method in accordance with claim 14 , wherein the predetermined gesture is a spinning gesture.
17. The method in accordance with claim 14 , further comprising counting personnel around the mobile device via thermal sensing.
18. The method in accordance with claim 14 , wherein the identification signal is one of a radio frequency (RF) signal and an infrared (IR) signal.
19. The method in accordance with claim 14 , wherein the identification signal includes one of a Bluetooth ID and a WiFi ID.
20. A mobile device comprising:
a movement sensor operable to generate a movement signal responsive to movement of the mobile device;
a signal sensor operable to receive wireless transmissions at the mobile device; and
a controller configured to detect via the movement signal that the mobile device has been moved in a predetermined gesture and, in response, to enter a personnel data collection mode wherein the mobile device receives via the signal sensor an identification signal from another device associated with a user and, in response, generates an identification of the user.
