Description

# of points 1, 5, 9, 16 Number of points in calibration sequence. A higher number can

increase the accuracy. The 16 points calibration is optimized for highest

accuracy. Head movement range is limited with 16 point calibration.

This method is designed for ALS users who want to control the Windows

desktop.

Target gaze accuracy 10, 20,

30, 40 mm

The accuracy that a particular subject can/should achieve.

The parameter does not influence the actual accuracy, but is only used

for qualitative calibration feedback, e.g. even a user with impaired eye

movement control can get 'good' results, when the target accuracy is

lowered.

Randomize points Y / N Changes the point sequence randomly to avoid prediction artifacts.

Play audio Y / N Sound feedback with point acceptance.

Slow mode Y/ N Slows down the automatic calibration process.

Shake marker Y/ N Shakes the marker after it moved to a new position to help attract users

attention at this position

Automatic

calibration

Y / N Cycles through the point sequence automatically, checking proper

fixation on each point.

When turned off, the operator has to accept each point manually.



ESC will cancel the calibration sequence at any time.

Skip bad points Y/ N After a while a non-fixated point will be ignored and the sequence will

continue.

When turned off, the system will wait indefinitely for a proper fixation.

Pick display colors n/a Colors for the calibration screen and targets.



Please pick the calibration background colors close to the

future operation scenario, in order to avoid gaze calcula-

tion artifacts through large pupil dilation changes, I.e.

calibrate on dark background, when the operation envi-

ronment will be dark.

Use image marker Y/ N Instead of the animated dot, a picture can be used as calibration target,

which can be particularly useful when calibrating children.

A dialog will allow the selection of a JPG, BMP or PNG image. The size

shall not exceed 256x256 px., color of the pixel 1,1 will be treated as

transparent image color.

Position calibration

area

Bottom,

Center, Full,

Horizontal,

Vertical

Very large screens or visually impaired subjects might require on

calibration only a part of the screen.



In most cases, the 1-point calibration on 'full-screen' will

yield similar results to a reduced calibration are .

Horizontal and Vertical options are only available with

5-point calibration.

Choose which eye to

calibrate

Both, Right,

Left

Selects which eyes will be used for the calibration.

Ignore r/l eye

completely

n/a When only one eye is selected for calibration, the option to completely

ignore the other eye comes up.

The second eye should only be completely ignored, if it's permanently

invisible, i.e. an eye-patch is being used.
