Mobile device sensor data subscribing and sharing

摘要

Techniques for mobile devices to subscribe and share raw sensor data are provided. The raw sensor data associated with sensors (e.g., accelerometers, gyroscopes, compasses, pedometers, pressure sensors, audio sensors, light sensors, barometers) of a mobile device can be used to determine the movement or activity of a user. By sharing the raw or compressed sensor data with other computing devices, the other computing devices can determine a motion state based on the sensor data. Additionally, in some instances, the other computing devices can determine a functional state based on the sensor data and the motion state. For example, functional state classification can be associated with each motion state (e.g., driving, walking) by further describing each motion state (e.g., walking on rough terrain, driving while texting).

主权项

1. A method for sharing sensor data, the method comprising:
receiving, at a computing device, an authorization to receive sensor data from a first mobile device, the authorization including an identifier associated with the first mobile device; receiving, at the computing device, information from the first mobile device, the information including the identifier and compressed sensor data from the first mobile device, wherein the compressed sensor data is derived from raw sensor data from one or more sensors in the first mobile device, the one or more sensors including at least one motion sensor and the raw sensor data including motion data from the at least one motion sensor; analyzing, with the computing device, the information to detect the identifier and to decompress the compressed sensor data to obtain the raw sensor data; and determining, by the computing device, a motion state of the first mobile device and a functional state associated with the motion state based on an analysis of the raw sensor data.
