Abstract:
1. An apparatus comprising: at least one sensor configured to sense electromagnetic radiation reflected from a surface; at least one projector configured to project electromagnetic radiation onto the surface or another surface; and a controller configured to generate control signals so as to direct the at least one projector and the at least one sensor to operate in modes including: the at least one projector projecting an alignment assist image to facilitate alignment of a field-of-vision of the least one sensor with one or more targets on the surface, wherein the controller identifies and analyzes a portion of an image captured by the least one sensor corresponding to a target based upon positioning of the alignment assist image on the surface while disregarding other portions of the image; and the at least one projector projecting a non-alignment assist image, wherein the non-alignment assist image is selected from a group of images consisting of: a target type request; an input request; a scanned target representation; a question; and a representation of a form to be filled based upon scanned targets existing on a surface to be scanned prior to the projection of the non-alignment assist image.
