Display environments for presentations are becoming diverse, and it is common to have multiple displays in the same room. We present a system to edit and give presentations using multiple displays. The main idea is to separate the content from the views. The author prepares presentation visuals (text and images) on an infinitely zoomable canvas, and then specifies what is shown in each display by dragging a rectangular display proxy onto the canvas. The presenter can change what is shown in each display by manipulating these display proxies. We describe an example that showed that the system can handle various presentation scenarios using multiple displays.
