NOTE:
In the above example the user cannot navigate to the rightmost region since the controller cannot
see an edge for that color. The user will only be able to navigate to the middle black region.
NOTE:
If more than one feature has the same color, the controller will only pick the first right edge with that
color from left to right. It is not recommended to use this mode if two features on the web have the same
color; Line mode or edge created by two colors may be a better option.
NOTE:
When the teaching is successfully saved, indicated by the disappearance of all other mode icons,
the user cannot change the brightness control state, the brightness gauge or the minimum contrast gauge.
Edge created by two colors
In this mode the controller will look for an edge created by a certain color on the left and certain color on the
right. Two regions will be highlighted along with the edge that is of interest (as shown below). The controller
will look for the first appearance of the exact match of the edge with the two colors on either side with the
appropriate order. Once the teaching is saved, all other modes will disappear and the gear icon will turn red.
Edge with two colors (Teaching)
Edge with two colors (Teaching Saved)
NOTE:
The Order of the colors matters in this mode. In the above example if the sensor is taught from gray
followed by black and if the order is reversed to black followed by gray (if the sensor is rotated 180°), the
controller will not pick that edge even though the two color regions are the same.
NOTE:
If multiple regions have the same color pair (such as in a barcode), the controller will always pick the
first pair from left to right. In that case the right edge of the color mode would be a better choice.
NOTE:
When the teaching is successfully saved, indicated by the disappearance of all other mode icons,
the user cannot change the brightness control state, the brightness gauge or the minimum contrast gauge.
Color of a line
In this mode any region with two edges can be used for tracking purposes. The controller will look for two
conditions to track the feature: (1) color and (2) the width of the color region. Since two conditions need to be
satisfied, this is one of the most robust modes. Once the teaching is saved, all other modes will disappear
and the gear icon will turn red. Once the teaching is saved, the controller always pick the first occurrence of
the color with a certain width while scanning from left to right
