IntelliGaze™ Installation & Service Manual Using IntelliGaze™

5.3.3 Calibration area

Sometimes cognitive weak or visually impaired users can't look into all corners of the monitor. When

you experience a systematic calibration error in one of the corners, you should shrink or move the cali-

bration area. The accuracy outside the calibration will be decreased. Make sure that buttons and cells

are larger when you want to use that region for gaze interaction. Some users can only look vertically or

horizontally. Choose the calibration area vertical or horizontal in this case. Make sure the buttons and

cells of a communication package are placed vertically or horizontally.

5.3.4 Cerebral Palsy

Cerebral Palsy users often move the head very fast. Make sure that the center of movement is also the

center of the working range at 60cm. It is recommended to use a one point calibration and large but -

tons and cells in the communication software. A simple and fast calibration with quick success reduces

the stress for the user.



The 16-point-calibration is designed for highest accuracy at the expense of a

possibly lowered head movement range. Do not use this calibration method

when the user moves his or her head a lot.

5.4 Monitor Calibration

In order to ensure the highest gaze accuracy over the large working range, the physical setup of the

system needs to be calibrated when the system is being integrated.

Upon first start you have to select which camera is used.



Integrated cameras don't have to be measured. Integrated cameras are using fixed pre-configured values. The

monitor tool will quit when you select the integrated camera. Neos13 is such a device with integrated cam-

era.

CAM30 and CAM30NT must be measured with the tool. The measurements cover the physical proper-

ties of the monitor and the position of the camera unit relative to it.
