You have to use the keyboard shortcuts to control Gaze Viewer with your keyboard to minimize the control menu.
|Gaze Viewer can be used with mouse/touch input or you can use keyboard shortcuts. The advantage of using keyboard shortcuts is that you don't have the Gaze Viewer control dialogue on top of your recording and you can control the recording with a keyboard which is less intrusive and distracting for the user.|
In recording mode there are three keyboard shortcuts:
F7 Record Gaze and Sound Recording: To start or stop the recording of Gaze and Sound recording
F8 Record Gaze only: To start or stop the recording of Gaze only recording
F9 Toggles Live Gaze on or off: to turn off or on live gaze while you are recording
All of them will automatically minimize the Gaze Viewer control dialogue.
