Summary: A method of dodging window interference is described for allowing multiple users to freely share any off-the-shelf single-user application in co-located collaboration utilizing a shared device. This method is indispensable for transparently realizing application sharing in light effort with a centralized architecture by using a surrogate window which is a mimic of the original application's window. Although the original application should process any event on the surrogate window, window interference could be caused by overlapping the location of an event with the surrogate window and then the event cannot be processed. To avoid window interference we formulate the method based on quadrant-based window positioning, in which the original application's window is dynamically repositioned for displaying only one quadrant of this window in one corner of the screen area. The availability of the proposed method was certified and the usability was clarified in co-located collaboration in a university laboratory.
