Quickstart Guide – IntelliGaze™ Desktop 2.0

Introduction

IntelliGaze Desktop 2.0 automation allows the user to operate the Windows desktop and standard Windows applications very conveniently by gaze control. Specialized eye controls help to manage frequent tasks, like drag and drop, cut and paste, scroll, and type text in many applications. Specialized interface functions allow to operate most Windows controls like buttons, menus and edit boxes directly without cumbersome, often unstable mouse, cursor positioning.

Prerequisites

2.1

Hardware

Minimum

Intel Atom N270 CPU, 1GB Ram, 12” Monitor, CAM30

Recommended

Dual Core CPU 2GHz, 2GB Ram, 17” Monitor, CAM30

2.2

Activation

 Desktop 2.0 requires an extended IntelliGaze license before it can be activated. Please contact you local distributor regarding upgrade options. How to check, whether the DT2.0 has been licensed (IG v2.x or higher):

The use of Desktop 2.0 can be enabled in the Application Center configuration (only on Windows Vista or 7).

Quickstart Guide – IntelliGaze™ Desktop 2.0

 You can still use the more direct mouse emulation provided in earlier version of IntelliGaze, by activating 'Mouse Emulation'.

 All application specific configurations entered into the Application Center are based on standard Mouse Emulation or direct data access (no changes to earlier versions).

 There are no user accessible, client application specific configurations for DT2.

Using Desktop 2.0

The DT2 mode can be entered at any time by selecting it from the Application Centers upper button bar. Special functions and mouse functions can be activated from side menus. Side menus are activated with an off-screen fixation and can be made 'sticky' with another off-screen fixation if the menu is visible. Non-sticky side menus will disappear after a few seconds of idle time. The status of the menu is visualized by a small needle icon at the top of the menu bars. The DT2 mode also includes a modified, automatic tracking status display that will appear in the upper center when necessary.

Tracking Status, Active L-Menu, Passive R-Menu

 The Desktop 2.0 mode can be exited on the configuration page by clicking the home button. Please find details below.

Mouse Menu – Left Side

The off-screen mouse menu can be accessed on the left side of the screen.

Single Left Click

Single Right Click, lockable*

Double Left Click, lockable*

Drag and Drop

*/ Locked Mouse actions will be used with every click until they are unlocked again. By default, Single Left-Click will be enabled after every other click action.

Drag and Drop Options Three different drag and drop options are available to allow the user either fast and coarse or very precise drag&drop or selection operations.



1. Direct, single click select and drop operation. 2. A magnifier will be opened. 3. The Position Helper will be used for very precise select and drop operation.

Quickstart Guide – IntelliGaze™ Desktop 2.0



The Position Helper tool does not place the mouse cursor directly at the gaze location, instead the position of the Windows cursor is moved according to the gaze position relative to a 'dead zone' (red circle). A fixation inside the dead zone initiates the mouse click. After the primary selection, the dead-zone shape changes to an octagon and the secondary selection can be completed as before.



All menu functions are disabled while a a drag&drop operation is in progress. 4.2

Special Functions Menu - Right Side Pause halts the gaze interaction, can be restarted with a second activation on the pause button. Enforce Magnifier will pop up the magnifier at the next activation on the screen. Scroll will open a scroll selection pop-up to choose between text scrolling and selection scrolling. Configuration allows to configure Desktop 2.0 settings.



When paused, the menu will disappear after 30s to allow undisturbed media-consumption or similar. Another off-screen fixation will bring the menu back.

Scroll Selection Two different scroll modes are available to choose between text scrolling operation and selection scrolling operation.

1. Text reading scrolling Used for reading long texts with automatic scrolling and minimal obstruction.  Exit with fixation on upper right exit icon.

2. Selection scrolling Used to select an item from a scrolling list of options. Exit with a fixation inside the scroll area.

4.2.1

Configuration Options

You can access the configuration options via the icon on the right side menu. Adjusts the dwell time relative to the global setting.

 The default dwell time in milliseconds is set in the system setup of IntelliGaze (tray icon menu).

Changes the magnification factor.

Selects one of max. three onscreen keyboards: Integrated keyboard, the Windows 7 OSK or a 3rd party keyboard (optional).

Changes the system volume level.

Toggles the 'click' audio feedback.

Permanently suppresses the automated lens.

 In some applications, i.e. games, it is favorably to suppress the lens. With excellent calibration, or adjusted screen settings you may also turn off the lens in standard applications to speed up usage of the desktop control.

Exit desktop 2.0 and return to the Application Center.

Close the dialogue and return the desktop.

4.3

Integrated Keyboard

A click inside an edit box or text field will automatically pop up a keyboard. Depended on the pre-selection of the setup menu, one out of three keyboards will be activated. Use either the integrated DT2.0 keyboard for easy typing, the Windows OSK which localized to several languages and provides word prediction or an optional third party keyboard which can be customized.

Integrated keyboard with local text feedback.

Shown above is the integrated DT2.0 keyboard. Buttons that are marked with a tiny triangle in the corner offer international variations of the letter when performing an immediate second fixation on the same button.

 The preview on top of the keyboard shows the content of the cursor even if the text field is hidden by the on screen keyboard. It's purpose is to provide quick, local feed-back.

4.4

Magnifier

A click in a region with small, crowded elements will automatically open the magnifier to allow precise selections.

Interactive Magnifier

The magnifier will always be opened in the middle of the screen. It provides a live view of the desktop, rather then a simple, static snapshot and shifted around by looking at or beyond the little arrows outside the central area. The operation can be canceled by looking at the top-right cross. The automation will always try to snap the cursor into elements. When there are overlapping elements and controls it can be advantageous to turn the automation off to prevent false selections. This can be done with the lower left button.



As constantly finding interactive GUI elements is a performance demanding task, slower PCs might fail to accomplish the calculations in realtime. The magnifier will then always pop up when the search for elements does not finish in time. A red frame on the magnifier indicates that it did open because of lack of processing power on the PC.

Touch Menu

Displays that have touch panel support can be used to bring up a menu to start the calibration or show the side menus with a finger tip. The touch menu will disappear automatically after a few seconds when not touched.

Client Applications

5.1

Recommended Applications

An increasing number of third party applications is providing UI automation features. IntelliGaze relies on these features to detect GUI elements, snap-in the cursor and offer eye controllable, easy access to those elements. While most applications provide some degree of a automation, the following applications have been positively tested and are recommended: • • • • • •

MS Office 2010 Internet Explorer 8 Firefox 5 or later Adobe Reader 10 Skype 5 Windows Live Mail 2011



Whenever applications lack support for full UI automation, the cursor will not snap in and the keyboard will not pop up automatically. Nevertheless, DT2.0 allows the operation of such applications with slightly reduced comfort.
