Abstract

A slider is rendered using one pel of dark grey as a border, with an inner border which is dark grey and white on the bottom (see Fig. 1). The conservative two-pel border is rendered on a default pale grey background which separates the control from the background. The slider knob is rendered to look three-dimensional and on top of the slider shaft. The incremental buttons and the combination of dark grey and white on pale grey lend just enough three-dimensionality to indicate to the user that the visual is a control upon which the user can act.

Slider Visual

       A slider is rendered using one pel of dark grey as a
border, with an inner border which is dark grey and white on the
bottom (see Fig. 1).  The conservative two-pel border is rendered on
a default pale grey background which separates the control from the
background.  The slider knob is rendered to look three-dimensional
and on top of the slider shaft.  The incremental buttons and the
combination of dark grey and white on pale grey lend just enough
three-dimensionality to indicate to the user that the visual is a
control upon which the user can act.

      Focus on the slider is shown simply by the appearance of a
black dot on the slider knob (see Fig. 1).  Visual studies indicated
that this signal would be enough to show focus without interrupting
the user's task.

      The detent has been designed to appear as a simple black arrow.
Its color and relationship to the slider make it easy to locate and
click on without disrupting the other increments around it.  (See
Figs. 1 and 3).  The detent re-sizes according to the slider shaft
width (see Fig. 3).

      To ensure visual excellence for the slider, it was necessary to
create an algorithm by which the slider would draw itself
consistently upon re-sizing.  The slider shaft was relatively
straightforward since, at even the largest sizes, the two-pel border
still maintained its separation from the background, indicating some
three-dimensionality.
