    摘要: A method of interacting with a printed substrate. The comprises the steps of: interacting with the substrate using an optically imaging pen having a nib; optically imaging target elements and coded data; calculating a position of the nib; and generating digital ink in the pen, the digital ink being indicative of the identity of the substrate and the position of the nib relative to the substrate; and sending the digital ink to a computer system such that the computer system can identify the interaction with the substrate. The position of the nib is calculated using the coded data, a perspective transform and a known spatial relationship between an optical axis of the pen and the nib. The perspective transform is determined using the imaged target elements which are perspective-distorted due to a tilt of the pen.
