IntelliGaze - 3 Modes of Operation

The IntelliGaze interface can be adapted to the actual user needs. Higher

levels include the functionality of lower levels:

1. Assisted Access Only -

A special use case, where a person guides the

user through a number of applications, i.e.

Look-to-Learn, and controls the gaze control

features frequently through a simplified Oper-

ation Center.

2. Direct Software Access (API) Only -

Only applications that have been set up to access IntelliGaze data

directly, i.e. Grid2, MindExpress4 or others can be controlled by gaze.

3. A.

Desktop / Full Control

Full gaze controlled access to all available functions, switches

look&feel automatically, depending on profile settings. Most func-

tions can be controlled via the Operation Center.

Safe Access

The access can be limited to pre-selected Windows applications by

enabling the 'Safe Access' option.

Mode 1 and 3a/b can be selected in the preferences section of the

software. Mode 2 is solely controlled by the client application.

Access to mode 2 and 3 requires an appropriately licensed camera.

Auxiliary Programs

Gaze Assistant

The Gaze Assistant program provides

guidance to measure and document

the gaze interaction capabilities of a

client. It splits the setup process into

small, well defined steps that help to

identify possible physiological issues.

The results can be saved into a digital document.

Reset IntelliGaze

A small utility to reset several groups of IntelliGaze parameters to their

installation values. Please use with care and consider backups!

Basic Operation

This section will provide a simple step-by-step guide on how to operate the

system for for general computer control.

1. Start IntelliGaze

The camera's illumination should show a dim red light and

the IntelliGaze tray icon will appear.

2. Position the camera - Ctrl-F1 / Operation Center

The monitor should be aligned with the user's head in about 60cm (2ft.)

distance. A straight look of the user should intersect the monitor in the upper

3rd, centrally.

The head position and automatic tracking can be validated by looking at the

Tracking Status Monitor in the Operation Center. The best

position is achieved, when the system shows a green smiley

in the center.

If the user should be wearing glasses, a more stable tracking might be achieved by

positioning the camera slightly lower than normal. Touching the Tracking Status or

Ctr-F10 provides a semi-live view of the user to better locate reflections.

3. Calibration - Ctrl-F5 / or via Operation Center

The system should be calibrated individually in order to achieve the best

accuracy for the user. It is recommended to calibrate both eyes while using

at least 9 points. Nevertheless options to cover a wide range of requirements

are provided. If the positioning above has been successful and the user's

condition does not pose any other challenges, the calibration will just pace

through a number of points, while waiting for the user to follow.

The results will be shown graphically, including a short qualitative feedback.

In complex cases, where a full calibration is too complex and limited accuracy is suffi-

cient, a 1-point calibration is recommended. IntelliGaze provides many advanced

options to calibrate even very complex case.

(see: Preferences → Calibration)

After a successful calibration the Operation Center can be

closed and gaze control will be enabled.

4. Controlling Desktop Applications

● Mouse Control - a gaze activated input, similar to a mouse, will be

enabled. By default, clicks will be initiated by dwelling on a target for

about 1 second,.

● Off-Screen Menus - By fixating just outside the monitor area, several

menus can be opened to select mouse and keyboard functions. (see

image below) The Operation Center (top) is always available and can

therefore be used to exit any application.

The side menus adapt to classic Desktop or Modern UI touch emulation.

They can be locked open by another gaze outside, which the small pin

icon will indicate.

All off-screen menus can be closed by another look in the same direction.

Beside mouse click selection, special functions for scrolling (pick from a

long list or continuously read text), drag&drop (direct or precise 'joy-

stick'), two finger touch (zoom and rotate) and Win8 system gestures are

provided.

A caretaker can help the user to open the side menus and OSK with

the keyboard shortcut Ctrl+Left/Right and Ctrl+Down

● The keyboard can switch between the pre-configured layouts.

● IntelliGaze will context sensitively try and automatically open the

keyboard or magnifier. This function depends on the underlying pro-

gram.

Customizing Gaze Control - Application Profiles

IntelliGaze v.4 introduces a completely new scheme to provide custom

gaze control behavior on a per-application basis. The former static

configuration has been replaced with dynamically loaded sets of opti-

mized parameters - Application Profiles.

Whenever a program is launched, IG tries to load a matching Application

Profile.

A small square in the upper right hand corner shows the current profile

name and key functions. IntelliGaze comes

with a constantly growing number of pre-

defined profiles. The included 'IntelliGaze

Application Profiles.PDF' document provides

a current list, download links and more

detailed information.

'Default' Profile

A Default Profile serves as a basis for all custom configurations and is

used as a fall-back for applications without special settings.

Whenever there is no desire for custom configurations, please consider

the Default Profile as a static, system wide setup. The Default Profile can

be easily customized:

OC > Options > Current Appl. > 'Open Profile Manager' > Select: Default > Edit

For a truly static behavior, all custom Application Profiles can be disabled

or removed in the Profile Manager.

Editing Profiles

All existing profiles can be edited like the 'default' profile above and new

profiles can be defined with a button press. All operations work with the

most recently active program, which is particularly helpful when working

with Windows 8 Modern UI applications.

Profile Parameters

The most significant settings of a profile can be seen in the Profile

Overview.

The Profile Editor provides a structured access to cursor settings (color,

size, behavior), menu and tool behavior and also allows the definition of

most sophisticated interactions using the two trigger channels, i.e. dwell

, switch and many system commands. All non-defined parameters will

be used, as defined in the Default Profile.

Application Center - Safe Access

The Safe Access mode allows to limit the

number of programs and Operation Center

functions that the user can access. It introduces

a full screen Application Center which serves

as a home page.

By using application profiles the gaze control

will be identical to full access mode.

To en-/disable Safe Access, please refer to:

Preferences > Operation Center > Safe Access

Entries can be defined under:

Preferences > Operation Center > Application Center

Alternatively the current application can be added directly:

Operation Center > Options > Current Application > 'Add to Application Center'

Grid2 Integration

Grid2 by Sensory Software has been modified to directly integrate with

IntelliGaze eye gaze control, providing a more seamless user experience.

While IG comes with a pre-defined application profile, Grid2 needs to be

configured manually:

User Settings > Input > Eye gaze > alea IntelliGaze

Calibration and click parameters can be set up in Grid2 and special

buttons for tracking status display, calibration control, etc. can be

included in grid sets.

Successively there are two methods to use Grid2:

1. Grid2 starts and ends IntelliGaze.

2. While IntelliGaze is running, the user launches Grid2 from the Windows

desktop or the IG Application Center.

The later option allows the user to switch between Grid2, Windows and

other applications autonomously while staying under gaze control.
