This application was built using the C programming language. A map of the District of Columbia area is displayed on the left. The homes that fulfill the criteria set by the user’s current query are shown as yellow dots on the map. Users perform queries, using the mouse, by setting the values of the sliders and buttons in the control panel to the right. The query result is determined by ANDing all sliders and buttons. The dynamic homefinder interface is best explained through an example. Take a hypothetical situation where a new professor, Dr. Jones, has just been hired by the Umversity of Maryland. She might encounter this tool in a touchscreen kiosk at a real-estate office or at the student union. She selects the location where she will be working by dragging the ‘A’ on the map. Next. she selects where her husband will be working. downtown, near the capitol, by dragging the ‘B’. Figure 2 shows the interface after Dr. Jones has dragged the ‘A’ and ‘B’ indicators to her desired locations (the indicators are more visible in Figure 4). 340 “The Dynamic HomeFinder: Evaluating dynamic queries in a real- estate information exploration system.” Christopher Williamson and Ben Shneiderman.
