5.4.3 Using Gaze Selection
The Gaze Selection mode of Windows Control makes it possible for the user to control a standard Windows desktop operating
system with a two step selection method which reduces the risks of unwanted clicks. It also prevents the following of the mouse
cursor with your gaze as opposed to the controlling of it (there is no floating mouse cursor in Gaze Selection).
1. The first step is to select the desired Task from the docked Taskbar by looking at it.
2. The second step is to look at the desired portion of the screen (or icon on the screen) where you want to execute the
Task. An automatic zoom function is enabled, ending in the selection of the icon or execution of the task.
All functions in Gaze Selection are Touch and Mouse enabled which makes it easier for a Caregiver or Assistant to
help the user if needed. The Caregiver or Assistant can select a Function/Task or change the settings for the user
much easier.
5.4.3.1 Gaze Selection Taskbar
At the top of the Gaze Selection Taskbar there is a Track Status viewer. It allows you to verify that the eye tracker recognizes
your eyes and that you are well positioned in front of the device.
The Task Buttons in the Gaze Selection Taskbar can be in three different modes as shown in Figure 5.3 The Modes for the
Gaze Selection Taskbar, page 30.
• 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.
