Abstract: A head-mounted device may include optical assemblies for presenting images to a user. The optical assemblies may be movable relative to one another. The head-mounted device may store a user-specific model for determining a distance between the optical assemblies and the user's face during operation of the head-mounted device. The user-specific model may predict when the distance between the optical assemblies and the user's face is too small based on measured input variables such as interpupillary distance, eye relief distance, vertical pupil position, and/or device tilt. The user-specific model may be generated based on a measured or inferred geometry of the user's nose and/or face. The user-specific model may be based on a face scan captured by a three-dimensional camera in the head-mounted device or in a separate electronic device.
