VISITview control panel

Adapted from http://www.ssec.wisc.edu/visitview/usage.html

The control panel

This is the Instructor/visit-local control panel as it appears upon executing visitm.bat or visitlocal.bat.

Example of the instructor/visit-local control panel

The control panel is organized into three areas of different functionality.

  1. From right to left, the first group (common to both students and master) is used to control which frame is being viewed on this page of the lesson, and how it is being shown. Please note that these controls affect everyone in the session! In the example shown, note that the word "Fade" is diminished in intensity. This means that for the page of the lesson being viewed, fading is not available.
    Graphic that explains all of the VISITview animation functionality

    Start/Stop animate button (instructor, local and student versions)
    This button becomes active (label turns dark) only if there is an animation on the current page. If the animation is off (on), the button is labeled start (stop), prompting you to start the animation. If you stop the animation, the "ViewClient" will freeze at the beginning.

    Rock/Loop button (instructor, local and student versions)
    This button toggles between a forward or rocking loop. It becomes active (label turns dark) only if there is an animation on the current page.

    Step forward/backward one frame (instructor, local and student versions)
    These buttons become active (label turns dark) only if there is an animation on the current page. If the animation is looping, clicking either button will freeze the animation in place.

    Toggle button (instructor, local and student versions)
    This button toggles between the current and last frame. It becomes active (label turns dark) only if there is an animation on the current page.

    Fade button (instructor, local and student versions)
    This button fades up to 4 images so that one image fades into another. It becomes active (label turns dark) only if there is an animation on the current page and the number of frames in the animation is less than 5. This function actually creates a large number of 'filler' images inbetween each frame in the loop. Some machines may take awhile to complete fader loop.

    Animation slider (instructor, local and student versions)
    This controls the animation speed. The label remains bold for pages with and without animations.

    Set frame/fade (instructor, local and student versions)
    This feature allows you to slide through frames or through a fading sequence. The label remains bold for pages with and without animations.

  2. The second set of controls is used for annotation (free-hand line drawing). You may select a color and a width (although the width is only for you, in case you want to make thin lines which may otherwise be obscuring some feature you want to look at in the underlying image).

    In order to draw, drag the mouse (that is, move the mouse pointer while holding the left button down). As you drag the mouse around, a line will be drawn in the color of your choice. As soon as you release the mouse button, the line is transmitted to all others. You will notice that when you let go of the mouse button, the line you've been drawing is erased briefly -- this is the time it takes to send the message to the server and have it resent back to you (and everyone else). You may also draw a rectangle by simultaneously dragging the mouse while pressing both the shift and Ctrl keys at the same time. A straight line may be drawn by pressing the Ctrl key and dragging the mouse. The line is set only after releasing the mouse button.

    Show Text/URL button (instructor,local and student versions)
    A unique web site link or a local file can be linked to each page in the lesson. This button provides you the ability to launch a browser and view any links that exist for this page. The label highlights (becomes dark) only if there is a link.

    Toggle blackboard on/off (instructor and local versions only)
    This button replaces the current page with a blank screen. This allows the instructor a clean space for annotations. Use the ESC button to restore the original page.

  3. The final set of controls are available only to the master session except for the enhancements control. They control, literally, what page you're on in the lesson.

    Label of Current Page and List pages for selection (instructor and local versions)
    This box shows the page number and label of the current page. By clicking on the 'list pages for selection' button to the right, this window expands to a scroll box. In place of this set of controls, the students will see the label of the current page as is shown here.

    Next button (instructor and local versions)
    This button usually highlights red when you execute visitm or visitlocal. The red highlight is prompting you to click on it thereby advancing the page to the beginning of the lesson.

    Prev button (instructor and local versions)
    This button goes to the previous page in the lesson.

    Selected button (instructor and local versions)
    This button will highlight in red if you scroll to another page using the 'label of current page' box. Click on it to skip to the desired page.

    Quiz functions
    Note that if there is a quiz.txt in the instructor's lesson directory, a quiz button will appear on the instructor's "ViewClient" control panel. If the current page number coincides with that of a quiz question, the quiz button will highlight in red. The student "ViewClient" control panel will not see this quiz button.

    Status button
    The Stat button will give the instructor an indication of the status of the last load command sent to all the students. The status results appear on the accompanying MS-DOS window (labeled JRE) that accompanies the "ViewClient". If there is no connectivity, two hyphens (--) appear in front of the client's (student's) address.

    Enhancements
    The bottom choice box is for enhancements. Students and instructors may select any enhancement from the choice list. As soon as an enhancement is selected, it will be applied to the image(s) on this page. Instructors may also change the enhancements in this list by modifying the file enh.tab before the lesson is compressed into an executable.
