[General]

The settings here didn't seem to fit specifically in any other setting, or they were overlapped with multiple sections.

enable_enter_click=false

This setting gets modified by the Enter Click button if it is on a toolbar and is used. The XML button id for it is: TOGGLE_ENTER_CLICKING

enable_spacebar_click=false

This setting gets modified by the Spacebar Click button if it is on a toolbar and is used. The XML button id for it is: TOGGLE_SPACEBAR_CLICKING

enable_custom_info=true

This instructs CaptainHook to utiliize the CustomExtraInfo parameter in the INPUT struct. This makes hooking the mouse and keyboard more seamless, but recent Windows updates disabled using this parameter on touch screen computers. Please see: http://answers.eyetechds.com/questions/128/mouse-stutter-jumpy-bad-clicking-laggy for information about which Windows updates affected this feature.

[email protected](-10 -10 120 120)

This limits the boundary where the mouse can be moved with eye tracking. This can be used to limit eye tracking to a sub-section of the screen, or a subsection of the visible area.

It is in percentages of the width and height of the screen, top-left-corner-x, top-left-corner-y, width, height. The parameters are space separated. So limiting gaze processing to only looking at the screen would be @Rect(-10 -10 120 120), to limit it to the inner 50% of the screen would be @Rect(25 25 50 50), to disable this setting completely and to allow eye tracking as far as the eyes can be picked up, set it to: @Rect(0 0 0 0)

The default Gaze-boundary setting is set to have a 10% border around the screen.

hide_cursor_on_exes=

This setting hides the cursor when the exe name has focus. The syntax for specifying programs is <program1.exe>, <program2.exe>, <...>. For example: hide_cursor_on_exes=notepad.exe, mspaint.exe

keyboard_stall_time=0.5

This setting is modified by the GUI setting Keyboard Stall Time found under the Settings (Gears) >CursorTab. The units for this setting are seconds.

This sets how long the eye tracker is stalled or temporarily paused after any key on the keyboard is pressed or released.

The same stall timer for the eye tracker can be restarted by a mouse move, a mouse click, or a key press. The most recent of the three sets the stall timer.

locale=

When specified this supersedes the detected local setting of the computer and will use the one listed here. The locale is specified with two letter abbreviations. Supported locales include: en, es, it, de, as of August 2014.

When not specified, QuickACCESS detects the language based on the Format specified in Region and Language in Control Panel.

mouse_click_stall_time=0.5

This setting is modified by the GUI setting Mouse Click Stall Time found under the Settings (Gears) >CursorTab. The units for this setting are seconds.

This sets how long the eye tracker is stalled or temporarily paused after the hardware mouse is clicked.

The same stall timer for the eye tracker can be restarted by a mouse move, a mouse click, or a key press. The most recent action of the three sets the stall timer.

mouse_movement_stall_time=3.0

This setting is modified by the GUI setting Mouse Move Stall Time found under the Settings (Gears) >CursorTab. The units for this setting are seconds.

This sets how long the eye tracker is stalled or temporarily paused after the hardware mouse is moved.

The same stall timer for the eye tracker can be restarted by a mouse move, a mouse click, or a key press. The most recent action of the three sets the stall timer.

options=-nl

This detects a few different command line options that QuickACCESS can be ran with. QuickACCESS checks these values in a few places. Here in the current User's ini file, in the system wide ini file, and actual command line arguments that QA.exe is ran with.

• -nl stands for No logging, and prevents extended logging.
• -l does logging of warning and critical messages to %temp%/QA_log.txt*
• -v does logging of debug and info and warning and critical messages to %temp%/QA_log.txt*
• -delay [seconds] where seconds is a integer, will delay the loading of QuickACCESS by [seconds] number of seconds. e.g. -delay 60 would delay the start by one minute.
• -no_qg forces the Quick Glance process to quit/end before QuickACCESS takes control of the eye tracker.

*If QA_log.txt exceeds 20 MB, on the next run of QuickACCESS it will be deleted and a new file will be created. Also when logging is turned on, a new entry in the System Tray Menu appears called Open Log File.

ScreenId=-1

This setting stores the current screen used by QuickACCESS. -1 indicates that it will use the default screen. This setting is modified by the GUI setting Monitor Select found under the Settings (Gears) >ToolbarTab.

This lets the user select which monitor to use with the eye tracker and with the toolbar. The asterisk, "*", indicates the "Primary" or "Main" screen as set in Windows.

[email protected](-1 -1 -1 -1)

This setting forces the mouse to move on-screen by a number of pixels before performing a click. The main purpose of this setting is to aid users that look at the edge of the screen and click intending to hit an icon or a scroll bar. Window's frames and decorations change across machines and screen resolutions, and being able to specify this setting is very useful for some users.

The default is that it is turned off: @Rect(-1 -1 -1 -1). To bring it in on all edges by 5 pixels you would use: @Rect(5 5 5 5).

spacebar_click_stall_time=0.4

This stall time gets triggered by Spacebar Clicking or Enter clicking. It is different from the keyboard stall time. So when the key is pressed and released, eye tracking is stalled by the number of seconds specified, e. g. 0.4 will stall the eye tracker for 0.4 seconds.

disable_keyboard_shortcuts_stall_time=2

When the keyboard is in use, not for clicking, this is the delay between the last key pressed and before clicking is available by the Spacebar or Enter key. This creates the smart keyboard detection where QuickACCESS is aware of if you are typing and allows access to the key that normally is dedicated to clicking.

enable_touch_screen_hook=true

This enables the detection and hooking of the touch screen and digitizer events that arrive as RawInput in Windows. This kind of hooking is very robust for handling the touch screen, but it doesn't stop the eye tracker and process the first screen tap at the same time. It requires that the first tap to disable the eye tracker and a second tap to do a regular mouse click. The alternative to using this touch screen hook is to make sure enable_custom_info is true and to turn this to false. For more information see:

http://answers.eyetechds.com/questions/240/touchscreen-two-taps

touch_screen_stall_time=5.0

When a touch screen is present on the computer, and it is touched or used, after the first touch, QuickACCESS disables eye tracking and touches after that are easily used and detected for clicking. The default is a 5 second timeout.

mouse_move_ignore_distance_x=0
mouse_move_ignore_distance_y=0

These two settings specify the minimum number of pixels the hardware mouse must be moved to cause an eye tracker stall. The move is across a single frame of movement, so > 100 pixels will typically disable the hardware mouse completely. This is useful if the end user uses a hardware mouse for clicking occasionally, but bumps the mouse while doing so. The amount of a typical bump can be entered here, so eye tracking won't be stalled accidentally.

[AEye]

The first two settings supersede the settings in the Eye Tracking section below. This setting is only accessed for TM5, VT3 or other cameras that are using the AEye eye tracking on a chip component.

LensFocalLength=1.2

The AEye trackers typically ship out with a 12 mm lens.

ImageProcessingAlgorithm=Legacy FPGA PCS Hybrid

This is the default algorithm in use by the AEye as of August 2014. As other algorithms are developed this setting may change.

blocking_calibration=false

This changes whether the calibration looks animated or not. For early versions of the AEye, an animated calibration would cause issues. This is no longer the case for all production versions of the AEye.

[Blink]

These settings deal with Blink or Blink+ in use as the Click Method for QuickACCESS.

blink_cancel_time=2.0

This is the amount of time in seconds that if the eyes are closed, it will be ignored as an eye gesture/event.

blink_long_time=1.2

This is the amount of time in seconds that if the eyes are closed, it will be interpreted as an eye gesture/event, typically a Double Click with the mouse when Blink+ is enabled.

blink_normal_time=0.3

This is the amount of time in seconds that if the eyes are closed, it will be interpreted as an eye gesture/event, typically a Single Left Click with the mouse when Blink or Blink+ is enabled.

blink_sounds=true

This enables sounds to know the timing of a blink when your eyes are closed. Three tones are played, a middle tone to indicate a Normal Blink click, a high tone to indicate a Long Blink click and a low town to indicate a Canceled Blink click. The associated files are found in the sounds folder: blinkCancel.wav, blinkLong.wav, blinkNormal.wav.

both_eyes_required=true

This setting changes whether both eyes are required to perform a click. This is useful for some individuals that are unable to close both eyes.

enable_blink_click=true

This setting associates blink clicking to perform a left click.

enable_long_blink_double_click=false

This setting associates a long blink click to perform a double left click.

required_fps=8

This is the minimum number of frames per second that the camera needs to be running at in order for blink clicks to be valid. Other setups when this setting is low frequently, this blink processing may be unreliable and have more false positives.

required_software_percent=15

This is the minimum percentage of frames that the computer needs to be processing from the camera in order for blink clicks to be valid. Other setups when this setting is low frequently, this blink processing may be unreliable and have more false positives. When the CPU is maxed out or the RAM is maxed out on a computer often, then blink clicking may be disabled temporarily by this setting until the computer is able to process frames again.

[Calibration]

These settings pertain to the calibration aspect of QuickACCESS. Use the calibration extras dialog to change most of these settings.

bg_color=gray

This is the background color of the calibration screen. It can receive colors, like standard CSS color values, and hex specified colors.

image=./images/calTarget.png

This is the png file used during the calibration. It is centered and resized down to fit in a 256x256 box.

distance=60

This is the calibrated distance so that the stats widget in QuickACCESS reports distances relative to this measurement. This does not affect the algorithm's tracking ability.

inbetween_targets_speed=1.5

This is the time in seconds in between calibrating on a target. The target animates traveling across a portion of the screen during this time. Use the calibration extras dialog to change this setting.

show_score=false

This sets whether or not a score should be shown after a calibration is completed. In this view of the score, the red lines represent measurements off the right eye and the blue lines off the left eye. The shorter the lines the better. Typically long lines indicate that a poor measurement was taken on a specific location of the screen. Sometimes it is indicative of a bad setup, or of the user not looking at the target. Other times it is caused by measurements taken from the wrong part of the image near the eye

spacebar_advance=false

This controls whether or not the calibration is automatic or requires the spacebar to be pressed in order to advance.

targetTime=1.3

This is the amount of time in seconds spent calibrating each target. The default of 1.3 has been required in the past for TM2, TM3, TM4, and VT2 eye trackers. Advanced users may consider shortening this time to much less, such as 0.5 seconds, especially with the AEye eye tracker.

type=16 Point

This is the default number of calibration points used. For some users, they may find just as high of accuracy with 9 or 5 point calibrations.

updateTime=2.0

This is the time in seconds that is used during the calibration update process (the single update point in the center of the screen).

use_sounds=true

This is whether or not sounds should be played on success of a calibration point.

rotate=true

This is whether the image should spin while shrinking during the calibration process.

[EyeTracker]

These settings are directly from the QuickLINK 2 API. Please see its documentation for detailed explanations. Below are brief summaries of the same info. The word Device precedes these settings when accessed directly in QL2. A number of these settings are easily edited on the Settings (Gears) > Eye (tab). Some additional ones can be pulled up by clicking View Addt'l Settings in the About QuickACCESS dialog.

BandwidthMode=Auto

The bandwidth mode the device will use. The available options are Auto and Manual. Auto mode trumps the two settings below: BandwidthPercentFull and BandwidthPercentTracking. The best way to edit this setting is to go to: System Tray Icon > About QuickACCESS > View Addt'l Settings, then it should show up under Settings (Gears) > Eye (tab) > Bandwidth % Full or Settings (Gears) > Eye (tab) > Bandwidth % Tracking.

BandwidthPercentFull=100

The percentage of the bus bandwidth used by the device when searching for eyes. When BandwidthMode is set to Auto, this value is ignored. Also note that for the VT2/EyeOn/VT2 Mini/EyeOn Mini, will use different settings. See the [VT2] section.

BandwidthPercentTracking=Auto

The percentage of the bus bandwidth used by the device when at least one eye has been found and is being tracked. The typical values are between 0 and 100. Auto only signifies in this case that it has been overridden by BandwidthMode up above. Also note that for the VT2/EyeOn/VT2 Mini/EyeOn Mini, will use different settings. See the [VT2] section.

Binning=1

The number of pixels to combine in the x and y direction.

CalibrateEnabled=true

The flag for enabling/disabling calibration.

Distance=60

The approximate distance in centimeters from the user to the device.

Exposure=10

The exposure time in milliseconds for each frame. Possible values range from 1-50 ms.

FlipY=false

Whether or not to flip the image on the X or Y axis.

GainMode=Auto

The gain mode the device will use.

GainValue=Auto

The gain value the device will use.

GazePointFilterMode=Smart

The filter mode for the output gaze point.

Standard modes selectable from the GUI are:

• Smart (aka Weighted Previous Frame, or Method 3 in Quick Glance)
• Classic (aka Median Time, or Method 2 in Quick Glance)

The Smart stability provides very quick responsive use of the eye tracker. The Classic stability can provide more smoothing than the Smart stability, but is less responsive. Default values used with each are stored in the [Stability] section

GazePointFilterValue=65

The value used for the filtering mode.

ImageProcessingAlgorithm=Legacy

This is the image processing algorithm used on eye trackers that don't have eye tracking on a chip.

ImageProcessingEnabled=true

The flag for enabling/disabling image processing.

ImageProcessingEyeRadiusLeft=1
ImageProcessingEyeRadiusRight=1

The calculated radii of the cornea of the eyes in centimeters. These radii will affect the calculated distance value that is output for each frame.

ImageProcessingEyesToUse=Left Eye and/or Right Eye

What eyes should be tracked and calibrated. For the default, both eyes are required on each target of the calibration.

InterpolateEnabled=true

The flag for enabling/disabling final gaze point interpolation.

LensFocalLength=1.6

The focal length in centimeters of the lens.

RoiMoveThresholdPercentX=4
RoiMoveThresholdPercentY=4

The horizontal distance in percentage of the image width that either eye can be from the left or right edge of the region of interest before the region of interest will move and try to re-center the eyes.

RoiSizePercentX=52
RoiSizePercentY=26

The dimensions of the region of interest in percentage of the sensor size when the eyes are being tracked.

display_refresh_fps=30

The maximum refresh rate of the camera when viewed through QuickACCESS's Live View window.

left_indicator_mode=4
right_indicator_mode=5

These modes control what is shown on each indicator light next to the camera lens. - 0 is always off. - 1 is always on. - 2 and 3 are the left and right current tracking status, unfiltered. - 3 and 4 are the left and right current tracking status, filtered, to reduce flickering.

[Eye_Dwell]

These settings are specific to when the eye clicking is in Dwell mode under Click Method.

animation=false

This is whether or not the dwell click should be animated.

dwell_sounds=true

This is whether or not a sound should be played when a click is performed.

enable_eye_dwell_click=false

This is whether or not dwell clicking is enabled.

eye_dwell_time=1.5

This is the time in seconds required to stare at a small region of the screen to perform a dwell click.

eye_dwell_area_width=3.5
eye_dwell_area_height=6.0

This is the dimensions of the region required to perform a dwell click, or in other words, if the path of the gaze points travels a region larger than this across the dwell time, then a dwell click won't be performed.

eye_dwell_lock_movement_percent=90

At what point into an eye dwell should the movement of the cursor get locked during a dwell. This is a percentage of the eye dwell time. 0 to 100 are available values.

no_dwell_exes=

This is a comma separated list of processes that perform their own click and dwell processing, and should not have dwell clicks performed on them.

idle_time=0.75

This is the time in seconds before the dwell action is considered idle and the cursor will be moved to a "parking space". Requires park_mouse_when_idle=true for it to work.

[email protected](0 100)

An x, y location measured from the top left corner of the screen, measured as a percentage of the screen's dimensions. The default value @Point(0 100) represents the bottom left corner of the screen. Requires park_mouse_when_idle=true for it to work.

park_mouse_when_idle=false

This is whether or not the parking of the mouse should be performed.

[HotKeys]

The hotkeys interface allows for any other program that can send key strokes, to be able to command different parts of QuickACCESS or to leverage some of QuickACCESS's integration with the mouse/keyboard/eyetracker.

The format is:

<Modifier>+<Modifer>+<Key>

or <modifer>+<key> or <key>

Such as: Ctrl+Alt+C or Ctrl+Shift+F3 or F7 etc.

But you need to restart QuickACCESS for it to find those new hotkeys.

The hotkeys are unique to each profile unless you edit the system wide hotkey list located here:

  C:/ProgramData/EyeTechDS/QuickACCESS.ini

Then newly created profiles will get its initial list of hotkeys from there.
