are, usually, incorporated into CASE system that
facilitate the construction of GUI operating environments. Examples
of these objects include Push Buttons, Scroll Bars, Scales, Spin
Buttons and many others.
Scale object is in the form of a slide (Fig. 1).
The mouse is used in order to alter the position of the Scales' arm,
which in turn, alters the magnitude registered by the Scale object.
The Scale can be oriented vertically or horizontally.
There exists problems with such an arrangement:
1. The Scale, in either orientation, consumes real-estate in
the vertical or the horizontally direction, which, at times,
interferes with the arrangement of other objects when sharing
same layout or "window".
2. To get an accurate representation of the relative magnitude
measured by the Scale. The size of the Scale object needs to
increased in size in the direction in which it is laid out.
aggravate the Problem in #1.
3. Analog dials have dominated the human interface since the start
of the industrial revolution. Humans find analog dials
and easy to read with only a glance. The present Scale object
violates that premise.
Radial Scale Object, as seen in Fig. 2, is in the
shape of a dial with the four quarters clearly marked. A permanent
Reference Arm marks the origin. When in use, a Sweeping Arm marks
the relative quantity being measured.
Arm will sweep clockwise for positive magnitudes
and counter clockwise for negative magnitudes. The area swept by the
Sweeping Arm in the positive direction will be filled with a color
that is different from that used to fill the negative swept area.
Example; if the positive swept area is colored red then the negative
swept area will be colored using a color...
