    摘要: Various arrangements for restricting mobile device usage are presented. A mobile device may collect movement and location sensor data. The mobile device may determine it is being operated within a moving vehicle based on the sensor data. The mobile device may use interaction data indicative of a user's interactions with the mobile device while the mobile device is being operated within the operating vehicle. An in-vehicle mobile device usage profile may be created based on the sensor data and the collected user interaction data. The in-vehicle mobile device usage profile may be analyzed to determine that a user of the mobile device is currently an operator of the moving vehicle. In response to determining that the user of the mobile device is currently the operator of the moving vehicle, access to one or more functions of the mobile device may be restricted.

    摘要: A vehicle maneuver detection application is proposed for driving assistant systems. The application can accurately and inexpensively detect and differentiate vehicle steering maneuvers by utilizing built-in sensors on smartphones or other portable computing device residing in a vehicle. By leveraging an effective bump detection algorithm and studying the nature of steering, the application is capable of differentiating various steering patterns, such as lane change, turn, and driving on curvy roads. Practicality of the application is demonstrates by two use cases: careless steering detection and fine-grained lane guidance. Thus, the application provides new functionalities without relying on cameras to provide a broader range of driving assistance.
