A method for use in obtaining input data from an object includes capturing a live image of the object with an image capture device, receiving information related to a tilt angle of the object from one or more sensors other than the image capture device, using the information related to a tilt angle of the object to obtain at least one rotated reference image of the object, comparing the live image of the object with the rotated reference image of the object, and generating an indication in response to the live image matching the rotated reference image. An apparatus and a storage medium storing a computer program executable by a processor based system are also disclosed
