Abstract: Systems, methods, and computer-readable media are disclosed for generating a baseline use profile that indicates typical patterns of use of a device over time, transitioning the device to a challenge mode when sensor data indicates a deviation from the baseline use profile by more than a permissible tolerance, presenting challenges to the user while in the challenge mode, and determining whether to restrict or allow access to device functionality based on user responses to the challenges.

Abstract: A handheld electronic device determines its position in a moving vehicle based on changes in air pressure that occur when the vehicle undergoes acceleration. Based on a direction of acceleration that correlates to a subsequent reduction in air pressure, a determination is made as to whether the device is in the front left, front right, back left, or back right quadrant of the vehicle. The device then alters its configuration based on the quadrant in which it is located.
