7. A computer-implemented method, comprising: detecting that a target object is within view of a camera associated with a mobile device; determining a duration over which the camera is oriented in a direction of the target object viewed in the camera; determining, based on the duration, an intent of a user to obtain additional information about the target object; capturing an image of the target object using the camera; identifying the target object within the captured image; and performing an action associated with the identified target object based on the intent of the user.
