An autonomous mobile device (AMD) may perform various tasks during operation. Some tasks, such as delivering a message to a particular user, may involve the AMD identifying the particular user. The AMD includes a camera to acquire an image, and image-based authentication techniques are used to determine a user's identity. A user may move within in a physical space, and the space may contain various obstructions which may occlude images. The AMD may move within the space to obtain a vantage point from which an image of the face of the user is obtained which is suitable for image-based authentication. In some situations, the AMD may present an attention signal, such as playing a sound from a speaker or flashing a light, to encourage the user to look at the AMD, providing an image for use in image-based authentication.
