Apparatus, systems, and methods for gathering and processing biometric and biomechanical data
Apparatus, systems, and methods are provided for measuring and analyzing movements of a body and for communicating information related to such body movements over a network. In certain embodiments, a system gathers biometric and biomechanical data relating to positions, orientations, and movements of various body parts of a user performed during sports activities, physical rehabilitation, or military or law enforcement activities. The biometric and biomechanical data can be communicated to a local and/or remote interface, which uses digital performance assessment tools to provide a performance evaluation to the user. The performance evaluation may include a graphical representation (e.g., a video), statistical information, and/or a comparison to another user and/or instructor. In some embodiments, the biometric and biomechanical data is communicated wirelessly to one or more devices including a processor, display, and/or data storage medium for further analysis, archiving, and data mining. In some embodiments, the device includes a cellular telephone.

wherein the sensors are coupled to the garment.
9. The system of claim 8 , further comprising a controller coupled to the garment and the sensors, wherein the controller coordinates data communication between the sensors and the transceiver.
10. The system of claim 9 , further comprising one or more actuators configured to provide haptic feedback to the first user;
wherein the actuators are coupled to the controller; and
wherein the haptic feedback is based on an alignment of the position of the first user and a reference position.
11. The system of claim 1 , further comprising the sensors, wherein the sensors comprise a pair of ultrasonic transducers configured to emit and/or receive an ultrasonic signal.
12. The system of claim 11 , wherein the position of the first and second limbs of the first user is based on a distance between the ultrasonic transducers, the distance determined using ultrasound signals communicated between the transducers.
13. The system of claim 1 , wherein the indication about the change in position between the reference limb position and the second limb position of the first user comprises information about an athletic performance of the first user.
14. A method comprising:
receiving position information from multiple sensors about a body of a first user, wherein the sensors correspond to respective first and second limbs of the body;
determining a change in position between a reference body position and a position of the first and second limbs of the first user based on the position information received from the sensors; and
using an interface device, providing an indication of the change in position as-determined.
15. The method of claim 14 , wherein providing the indication includes providing an audible signal to the first user or to another user using the interface device.
16. The method of claim 14 , wherein providing the indication includes providing a visual signal to the first user or to another user using the interface device.
17. The method of claim 14 , wherein providing the indication includes providing a haptic or tactile signal to the first user using the interface device.
18. The method of claim 14 , wherein receiving the position information includes receiving the position information while the first user performs an athletic activity; and
wherein providing the indication of the change in position includes providing information about a change in a position of the first and second limbs of the first user relative to the reference body position as the first user performs the athletic activity.
19. The method of claim 14 , further comprising using the interface device, providing information about an athletic performance metric based on the change in position as-determined.
20. The method of claim 14 , further comprising using the interface device, providing athletic instruction information to the first user, the athletic instruction information based at least in part on the change in position as-determined between the reference body position and the position of the first and second limbs of the first user.
