1. A method comprising:
obtaining, by a mobile device, a first signal indicating an acceleration measured by an accelerometer over a time period, and a second signal indicating an orientation measured by an orientation sensor over the time period, wherein the accelerometer and the orientation sensor are physically coupled to a user;
determining, by the mobile device, rotation data indication an amount of rotation experienced by the user during the time period;
determining, by the mobile device, that the user has tumbled based on the rotation data; and
responsive to determining that the user has tumbled, generating, by the mobile device, a notification indicating that the user has tumbled.
