A user controls, by hand, relative positioning between a camera-equipped apparatus and an object, to vary image data captured by the apparatus. At least certain of the image data is processed in connection with automated recognition of the object. An action based on recognition of the object can be taken. The arrangement further includes presenting feedback data to help guide the user in connection with said positioning, so as to aid in capturing image data from which the object can be recognized. In another aspect, the apparatus can provide a sequence of state data to the user on a display device, to indicate progress through several states in connection with the object recognition. A great variety of other arrangements and technologies are also detailed.
