Facilitating aligning a user and camera for user authentication
First Claim
1. A method comprising:
- obtaining an image of a user captured by a camera;
determining whether the user is within an interaction zone, the interaction zone comprising an area bounded by both a field of view of the camera and a distance range suitable for identifying features of the user from an additional image of the user captured by the camera, the distance range comprising a set of distances between an upper threshold distance away from the camera and a lower threshold distance away from the camera, the set of distances for the camera for a type of recognition being used for identifying the features of the user being accessible to a module performing the determining; and
providing feedback indicating whether the user is within the interaction zone, the feedback comprising one or a combination of audio feedback, visual feedback, and haptic feedback.

Abstract
A user is authenticated based on user features that can be captured by a camera, such as facial features or eye features. In order for the user to be authenticated, an image is captured of the user while the user is within an interaction zone, which is an area that is within both a field of view of the camera and a suitable distance range from the camera. If the user is not within the suitable distance range from the camera, then feedback is provided indicating that the user is not within the suitable distance range from the camera. Various feedback can be provided, such as one or a combination of audio, visual, and haptic feedback. The feedback notifies the user that an adjustment is to be made to the location of the user and/or the camera in order for the user to be within the interaction zone.

9. A device comprising:
-
one or more processors; and a computer-readable storage medium having stored thereon multiple instructions that, responsive to execution by the one or more processors, cause the one or more processors to perform acts comprising; obtaining one or more images of a user captured by a camera; determining whether the user is within a suitable distance range for identifying features of the user from at least one of the one or more images of the user, the suitable distance range comprising a set of distances between an upper threshold distance away from the camera and a lower threshold distance away from the camera, the set of distances for the camera for a type of recognition being used for identifying the features of the user being accessible to a module performing the determining; and providing feedback indicating whether the user is within the suitable distance range, the feedback comprising one or a combination of different types of feedback that can be sensed by the user. - View Dependent Claims (10, 11, 12, 13, 14)

- 15. A device comprising a camera, a user alignment system, and one or more feedback components, the camera being configured to capture one or more images of a user, the one or more feedback components being configured to receive an indication of whether the user is within a suitable distance range for identifying features of the user from at least one of the one or more images of the user, the suitable distance range comprising a set of distances between an upper threshold distance away from the camera and a lower threshold distance away from the camera, the set of distances for the camera for a type of recognition being used for identifying the features of the user being accessible to a module determining whether the user is within the suitable distance range and to provide feedback indicating whether the user is within the suitable distance range, the one or more feedback components being also configured to provide one or a combination of audio feedback, visual feedback, and haptic feedback.
