Abstract: Rider location and acceleration sharing systems are provided herein. For instance, a system is paired with a wireless transceiver, mountable to or within headwear that outputs location data and accelerometer data associated with the user identity to a user device. Once members of the group of user devices are validated for movement together, an emergency event associated with a member of the group may be identified based on the accelerometer data or the location data, and, in response to the emergency event, emergency event data is sent to the respective other user devices, and other information is enabled to be received from any of the respective other user devices.

Abstract: Various helmet communication, entertainment, and safety techniques are enabled. For instance, a method comprises receiving, by a helmet user-interface system comprising a processor, an output from a sensor, determining, by the helmet user-interface system, whether the output comprises gesture information representative of a gesture, in response to the determining and based on a condition being determined to be satisfied, identifying, by the helmet user-interface system, a gesture type associated with the gesture information, and executing, by the helmet user-interface system, a function associated with the gesture type.
