GeoSpace provides users with two types of interaction. First, the user can use text or speech to enter a query to which the system responds using the mechanism described above. Second, the user can use the mouse to zoom, pan, and move around the two and three dimensional map display.
First, the user asks the system “Show me Cambridge.” Then, the label Cambridge increases in opacity to bring this information to the user’s attention. The typographic size also changes accordingly, resulting in a sharper focus of Cambridge. Notice also that related information such as hospitals, highways and colleges around Cambridge are also identified visually to a slightly lesser degree. This demonstrates the reactive nature of discerning information rapidly in a visually dense environment.
