Outline Introduction Strategies Detailed Description Examples Compared to Donald’s scrollbar
Introduction Various visualization and information
retrieval techniques have been proposed. In some systems, visualization and filtering
are integrated. Most existing systems suffer from:
applicable only to special application domains Special interaction techniques are usually
required.
Introduction(Cont.) They propose a interface tool called LensBar for fi
ltering and visualizing large data lists. an extension to a conventional scroll window
Strategies Browsing the list using a precisely-
controllable slider and scroll window. Controlling the amount of data to be
displayed by keyword filtering and zooming. Visualizing the distribution of filtered data in
the background of the slider.
Detailed Description Integrated browsing and querying
a slider & an extra text input area Entries that match the specified pattern are
displayed in the scroll window. Corresponding positions in the slider background
are highlighted to show the locations. Slider knob moves only on the highlighted portion.
Detailed Description(Cont.) Dynamic approximate string matching Zooming interface
A DOI value is dynamically assigned to each entry. Entries whose DOI value is bigger than the
zooming level are selected for display. Precise control of the slider
Clicking the mouse on the slider knob allows the user to move the knob directly to any place on the bar.
Example 1 - dictionary
Example 1(Cont.)
Example 2 – message browser
Example 3 – program browser
Example 4 – hierarchical menu
