     DETAILED DESCRIPTION 
       [0015]      FIG. 1  illustrates various systems  2 . As shown in  FIG. 1  there is a pair of earpieces  10 , which includes a left earpiece  12 A and a right earpiece  12 B. A vehicle is shown in the form of a motorcycle  18 . In operation, the set of earpieces  10  may communicate with the motorcycle  18 . 
         [0016]    The motorcycle may include one or more inertial sensors such as a first inertial sensor  14 A and a second inertial sensor  14 B. In addition, the motorcycle has its own electronic control unit (ECU) or other control system  16 . The control system  16  may include a wireless transceiver for operative communication with wireless transceivers in one or more of the earpieces  12 A,  12 B. The earpiece and the control system may be configured to exchange inertial data sensed by the earpiece(s)  12 A,  12 B and inertial data sensed by the inertial sensors  14 A,  14 B of the vehicle  18 . 
         [0017]      FIG. 2  illustrates the set of earpieces  10  including the left earpiece  12 A with a left earpiece housing  14 A and the right earpiece  12 B with a right earpiece housing  14 B. An external microphone  70 A is present on the left earpiece  12 A and another external microphone  70 B is present on the right earpiece. More than one external earpiece may be present on each earpiece. 
         [0018]    A touch area  19 A is present on the left earpiece and a touch area  19 B is present on the right earpiece. In operation, a user may control functionality of the earpieces through interacting through the touch interface. This may include tapping on the touch area, swiping across the touch area (with different directionality having potentially different meaning), or holding a finger against the touch area. 
         [0019]      FIG. 3  illustrates one example of a block diagram of an earpiece. As shown in  FIG. 3 , the earpiece may include one or more sensors  32 . Examples of sensors may include an air microphone  70 , a bone microphone  71 , an inertial sensor  74 , another inertial sensor  76 , and one or more biometric or physiological sensors  78 . The inertial sensors  74 ,  76  may include accelerometers, gyros, or other types of inertial sensors. For example, each inertial sensor may be a 9-axis inertial sensor which includes a 3-axis gyroscope, a 3-axis accelerometer, and a 3 axis compass. Of course simpler forms of inertial sensors or more complex forms of inertial sensors may be used instead. 
         [0020]    The biometric sensors  78  may include any number of different physiological sensors including heart rate monitors, pulse oximeters, temperature sensors, or other type of physiological sensors. An intelligent control system  30  is shown which may comprise one or more processors. A gesture control interface  36  is operatively connected to the intelligent control system  30 . The gesture control interface  36  may include one or more emitters and one or more detectors  84  which are used to sense gestures of a user such as a user tapping, holding, or swiping across a touch area of the earpiece. The sensors may provide for capacitive sensing, infrared sensing, other types of light sensing, or other type of emittance and reception to detect types of gestures performed at a touch surface of the earpiece. The intelligent control system  30  is also operatively connected to one or more speakers  73 , one or more light elements such as LEDs  20 , a memory or storage unit  60 , and one or more transceivers  34 ,  35  which may include a wireless radio transceiver  34  such as may be used for Bluetooth or Bluetooth Low Energy (BLE) communications, or Wi-Fi communications, ultra-wideband, or other type of wireless radio communications such as with other wearable devices, with the motorcycle or other vehicle, with the helmet, with a protection system or otherwise. The transceiver  35  may be a near field magnetic inductance (NFMI) or other type of transceiver which may be used to communicate between earpieces and/or for other purposes as well. 
         [0021]      FIG. 4  illustrates one example of a simplified motorcycle control system  16  where one or more processors  210  are shown. The processors  210  may be operatively connected to a wireless transceiver  202 , any number of inertial sensors  204 , a geolocation receiver  206 , one or more displays  208 , a navigation system  214 , an entertainment system  216  or other systems. 
         [0022]    Information from the inertial sensors  204  of the motorcycle may be communicated to the earpieces(s). Similarly, information from the inertial sensors of the earpiece may be communicated to the vehicle. A two-way exchange of inertial data is beneficial in a number of ways. For example, the control system of the vehicle may predict movement of the driver of the motorcycle based on head movement. Thus, when a driver first begins to move, inertial data may be sensed with the earpieces before there is any inertial change detected by inertial sensors on the vehicle itself. Thus, the vehicle may predict movement based on user movement to make any adjustments desirable in advance or in synchronization with the movement. Such adjustments may include stability control adjustments, anti-lock brake system adjustments, traction control system adjustments, and other types of vehicle control adjustments. Where the vehicle is a motorcycle, movement of a user such as sensing that a user is beginning to lean in a particular direction may be detected from inertial sensors in earpieces prior to being sensed at the vehicle. 
         [0023]    In addition, inertial change data may be communicated to the earpieces in order to provide audio feedback instead of or in addition to being displayed on a display of the vehicle. 
         [0024]    It is also contemplated that earpieces may be worn by a passenger of the vehicle in addition to or instead of the driver of the vehicle. For example, when the vehicle is a motorcycle, operation of the vehicle is affected both by the driver and the passenger. If a passenger is inexperienced and leans too much or leans in the wrong direction, this may create issues for the driver. In one embodiment, both inertial data from earpieces of the driver and inertial data from earpieces of the passenger are communicated to the motorcycle and the motorcycle may provide audible instructions to the driver and/or the passenger through the earpieces regarding the timing or amount of their leaning. 
         [0025]    Therefore various methods, systems, and apparatus have been shown and described herein. Although various embodiments have been shown it is to be understood that numerous variations, options, and alternatives are contemplated. This includes variations in the particular sensors of the earpiece, sensors of the motorcycle or other vehicle and variations in any number of variations in the structure, functions, and control methodologies used.
