•
Normal (Unselected)
- No Task Button for Gaze Selection is chosen.
•
Primary Selection (Blue/black)
- The marked Task Button is selected and the Task will be executed after the auto-
matic zoom when the user looks at the desired position on the screen or icon on it. If the selection method is set to
Switch in the Gaze Selection Settings Dialog, the chosen Task Button will still remain active after executing the Task.
The Functions Overlay Task will not perform any zooming. When selecting Functions Overlay with Primary Se-
lection, the Functions Areas/Commands will be active but not visible.
•
Secondary Selection (Blue/white)
- Same as
Primary Selection
but with a higher precision.
Primary Selection
means that the zoom will progress deeper before the final execution of the Task, making the desired portion of the
screen bigger and easier to select within. Activate this mode by resting your gaze on the Task Button until the color
changes according to the image below.
The Functions Overlay Task will not perform any zooming. When selecting Functions Overlay with Secondary
Selection, the Functions will be active and the areas of each Function will be visible to the user.
In Windows 8 the colors on the Taskbar will adapt to Windows settings.
The Functions Overlay will not perform any zoom, some other tasks won't either in some situations (scroll, settings,
keyboard).
