Abstract
Display surfaces such as catalog items, for example, are displayed in one-dimensional order in a corridor perspective which may be based on one or more points. An input-initiated, processor-controlled dollying effect facilitates visual access, navigation, and browsing to the display surfaces. Within a surface, an input-initiated panning option can be provided, and the scale at which a surface is displayed can be changed. Input may be via a mouse, a light pen, a touch-sensitive screen, a keyboard, a track ball, a touch pad, or voice-activated control.
Claims14
A display system comprising a two-dimensional graphical display device, processor means operationally coupled to the display device for forming a display of a plurality of one-dimensionally ordered planar display surfaces on the display device, and input means operationally coupled to the processor means for controlling the display, wherein the processor means is instructed:
- for forming the display such that the display surfaces appear in a corridor perspective in their one-dimensional order, wherein each display surface has at least one extended masthead within the plane;
- for receiving dollying control input from the input means;
- and
- for changing the display in response to the dollying control input so as to produce a display effect which gives a viewer of the display a perception of dollying along the corridor perspective.
A computerized method for displaying a plurality of one-dimensionally ordered planar display surfaces on a two-dimensional graphical display device, comprising:
- forming a display on the display device such that the display surfaces appear in a corridor perspective in their one-dimensional order, wherein each display surface has at least one extended masthead within the plane;
- receiving dollying control input from an input means;
- and
- changing the display in response to the dollying control input so as to produce a display effect which gives a viewer of the display a perception of dollying along the corridor perspective.
