1. A method of generating a three-dimensional (3D) model of a face of a user, the method comprising:
under control of a wearable device comprising computer hardware, a display device configured to display a 3D environment to the user, an imaging system configured to image a portion of the face of the user, and an inertial measurement unit (IMU) configured to detect movements of the display device:
detecting, by the IMU, a trigger for imaging a face of the user, wherein the trigger comprises determining that an acceleration of the display device passes a threshold acceleration;
capturing, by the imaging system, images of at least a portion of a face of the user;
analyzing the images captured by the imaging system; and
generating the face model based at least partly on the analysis of the images.
