Speed Control Slider

      This disclosure presents a method for controlling multimedia
playback at any intermediate speed and direction, while still
offering direct access to standard speeds without taking additional
space.

      Some devices and media formats allow playback at varying speeds
(and direction).  Typical multimedia control panels (with play, fast
forward, reverse, etc.) do not fully utilize this capability.

      The solution uses a horizontal slider to indicate and control
speed and direction.  The center of the slider represents no
movement.  Forward speed increases to the right, and reverse speed
increases to the left.

      Instead of numeric indicators for frame rate or sample playback
speed, graphical symbols on the slider are used which correspond to
the industry standard transport control symbols.  The standard
symbols for 'play normal speed' (>), 'fast forward' (>>), 'stop',
etc., are used to indicate detents in the slider where these speeds
and directions correspond (Figure).

      Since these are detents, they are as easy to activate as a
standard transport control panel button; thus, this one control
combines the advantages of a slider and a typical multimedia control
panel, preserving the same interaction techniques, while occupying no
more space than a slider alone.

      The graphics can be placed in the slider shaft itself, or below
it.  When clicked, they act as detents, moving the slider to that
value.
