As computers become more ubiquitous, traditional two-dimensional interfaces must be replaced with interfaces based on a three-dimensional metaphor. However, these interfaces must still be as simple and functional as their two-dimensional predecessors. This paper introduces SWiM, a new interface for moving application windows between various screens, such as wall displays, laptop monitors, and desktop displays, in a three-dimensional physical environment. SWiM was designed based on the results of initial "paper and pencil" user tests of three possible interfaces. The results of these tests led to a map-like interface where users select the destination display for their application from various icons. If the destination is a mobile display it is not displayed on the map. Instead users can select the screen's name from a list of all possible destination displays. User testing of SWiM was conducted to discover whether it is easy to learn and use. Users that were asked to use SWiM without any instructions found the interface as intuitive to use as users who were given a demonstration. The results show that SWiM combines simplicity and functionality to create an interface that is easy to learn and easy to use.
In Stanford's iRoom, the PointRight system allows users to use a single mouse and keyboard to control multiple dis -plays. @cite_0 Changing displays is accomplished by simply moving the cursor off the edge of a screen. Currently, iRoom does not move applications across displays, but this mouse technique could be extended to dragging application windows as well.

We describe the design of and experience with PointRight, a peer-to-peer pointer and keyboard redirection system that operates in multi-machine, multi-user environments. PointRight employs a geometric model for redirecting input across screens driven by multiple independent machines and operating systems. It was created for interactive workspaces that include large, shared displays and individual laptops, but is a general tool that supports many different configurations and modes of use. Although previous systems have provided for re-routing pointer and keyboard control, in this paper we present a more general and flexible system, along with an analysis of the types of re-binding that must be handled by any pointer redirection system This paper describes the system, the ways in which it has been used, and the lessons that have been learned from its use over the last two years.
