Abstract
Input is provided to an application using a plurality of physical objects disposed adjacent to an interactive display surface. A primary location is determined where a primary physical object, e.g., a finger or thumb of the user, is positioned adjacent to the interactive display surface. An additional location is determined where an additional physical object is positioned adjacent to the interactive display surface. The attribute might be a size of an image or selected portion of the image that will be retained after cropping. A change in position of at least one of the objects is detected, and the attribute is adjusted based on the change in position of one or both objects. A range of selectable options of the application can also be display by touching the interactive display surface with one's fingers or other objects, and one of the options can be selected with another object.
