This paper describes a distortion-oriented visualization technique that uses a curve or a polygonal line as a focus, other than a point or an area, and discusses possibility of realization and applications of that method. Fisheye view is a representative method to visualize a large information structure. Like a fisheye lens, it magnifies neighborhood of user’s focus in detail and continuously reduces magnification factor to distance. Conventional fisheye visualizations use single focus point in a view and several methods can use a set of multiple focus points. Using a line or a simple shape is also proposed. However there are few discussions about using a curve or a polygonal line as a focus. So, we propose a curve focus inputted by user’s free drawing with mouse or pen, and describe its applications and several prototype transformations.
