Abstract

Distortion oriented displays (DOD) are an interface approach for supporting navigation through large visual datasets (maps) without losing context. The traditional approaches of windowing and zooming lead the user to lose context within the overall map. DOD present the user with a movable virtual magnifying glass within which a detailed view of the point of focus is presented. Surrounding this the rest of the map is presented in a visually compressed view to ensure context is retained. An important feature of a DOD is that the user should be able to move the point of focus around the screen and experience no discernible delay in the redisplay of the map. Therefore the computation overhead is very important when considering the implementation of a DOD. This paper describes FRUSTUM, a novel form of DOD with low apparent distortion and minimal computational overhead. Experience with the FRUSTUM display has indicated that considerably higher magnification factors are possible than the generally accepted maximum for previously described DOD.
