Abstract:

This poster describes an interaction technique called variable density scroll area (VDSA) to assist in the browsing of large datasets. This technique actively supports the user in the task of browsing by allowing the user to scroll through a dataset with the ability to change the resolution of the scrolling action. It employs two major principles. First, we provide a two-dimensional scroll area in which scrolling occurs. The complete dataset is represented as a column displayed on the left edge of this area. By providing this context, the user is always able to determine the location of the current results within the entire dataset. The remainder of the scrolling area is used to refine the resolution of the scrolling action. The second principle involves the use of rapid serial visual presentation (RSVP) for displaying the chosen data in a fixed location. In the interface, the user can focus on this fixed location to see the data rapidly presented as they scroll through the large set of possibilities.
