Abstract
Output of a computer system is manipulated using a physical object disposed adjacent to an interactive display surface. A painting application produces an image in response to an object disposed adjacent to the interactive display surface. During each of a plurality of capture intervals, a set of points corresponding to the object is detected when the object is disposed adjacent to the interactive display surface. An image is projected onto the interactive display surface representing the set of points and is filled with a color or pattern. As successive sets of points are accumulated during each of a plurality of capture intervals, a composite image is displayed. An object can thus be used, for example, to “draw,” “paint,” or “stamp” images on the display surface. These images manifest characteristics of the object and its interaction and movement relative to the interactive display surface in a realistic manner.
