RGB Color Input Method Using Directional Gestures

       Disclosed is a method for interactively inputting color
data by using a mouse, tablet, or any other pointing/stroking device.

      Color data can be specified by a triplet, such as the primary
colors (red, green, and blue) or three attributes (hue, brightness,
and saturation). Consequently, existing methods for the input of
color data support three sliders, as shown in Fig. 4. In these
methods, users must first select a slider and can then input the
color data assigned to that slider. Thus, there are two modes: one
for selecting a slider and the other for inputting the data. The
existing methods require frequent alternation between the slider
selection mode and the data input mode, because color input usually
involves repeated trial and error. This increases the workload of the
input operation.

      The advantages of the disclosed method over the above existing
methods are as follows:

      The selection of the primary colors and the input of the
selected color values are made modeless by six directional gestures,
which are defined as the movement of a mouse or tablet pen in one of
six directions, as shown in Fig. 1. A directional gesture is
position-free, and thus a user can repeat it without resetting the
position of the mouse or tablet pen. The selection and input are also
modeless, because the six directional gestures represent both
selections of primary colors and commands to increase/decrea...
