Tobii PCEye Go User’s manual v.2.8 - en-US

1 Introduction

1. Requires an Environmental Control Unit (ECU) and separate senders and receivers, not included with the Tobii PCEye Go.

2 Safety

The Tobii PCEye Go has been tested and approved as compliant to all the Specifications and Standards listed in the Appendix B Compliance Information, page 55 in this manual and in the Appendix D Technical Specifications, page 58 -- including, but

not limited to, the Medical Device Directive (MDD) 93/42/EEC. Nevertheless, in order to ensure safe operation of your Tobii PCEye Go device, there are a few safety warnings to bear in mind:

2.1 Mounting Warning

The Tobii PCEye Go should be mounted according to MANUFACTURER instructions of approved mounts. Tobii Dynavox or its agents are not liable for damage or injuries to a person or its property due to a Tobii PCEye Go falling from a mounted configuration. The mounting of a Tobii PCEye Go is done entirely at the user’s own risk.

The double sided tape supplied with the adhesive Magnetic Mounting Plates is designed to permanently attach the bracket to the monitor/laptop. Attempting to remove the bracket after attaching it using the supplied tape can result in damage both to the monitor/laptop and the bracket.

Do not lick the tape or place any part of the tape or Magnetic Mounting Plate in one's mouth.

Do not mount the Tobii PCEye Go on monitors positioned above the head or face of a users unless using a dedicated "fixed mounting" solution.

2.2 Emergency Warning

Be aware that due to the low, but possible, risk of failure, the Tobii PCEye Go should not be relied upon exclusively as an audio communications, or an environmental control, device in emergencies, as well as in dangerous, or otherwise important, situations. Do not rely on the device for emergency calls or banking transactions. We recommend having multiple ways to communicate in emergency situations. Banking transactions should only be carried out with a system recommended by, and approved according to the standards of, your bank.

2.3 Infrared Warning

When activated, the Tobii PCEye Go emits pulsed infrared (IR) light. Certain medical devices are susceptible to disturbance by IR light and/or radiation. Do not use the Tobii PCEye Go when in the vicinity of such susceptible medical devices as their accuracy or proper functionality could be inhibited.

2.4 Epilepsy Warning

Some people with Photosensitive Epilepsy are susceptible to epileptic seizures or loss of consciousness when exposed to certain flashing lights or light patterns in everyday life. This may happen even if the person has no medical history of epilepsy or has never had any epileptic seizures.

A person with Photosensitive Epilepsy would also be likely to have problems with TV screens, some arcade games, and flickering fluorescent bulbs. Such people may have a seizure while watching certain images or patterns on a monitor, or even when exposed to the light sources of an eye tracker. It is estimated that about 3-5% of people with epilepsy have this type of Photosensitive Epilepsy. Many people with Photosensitive Epilepsy experience an "aura" or feel odd sensations before the seizure occurs. If you feel odd during use, move your eyes away from the eye tracker.

2.5 Magnetic Field Warning

The Tobii PCEye Go Magnetic Mounting Plates contains magnets. Magnetic fields may interfere with the function of cardiac pacemakers and implantable cardioverter-defibrillators. As a general rule, maintain a minimum distance of 6 inches (15 centimeters) between any item with magnets and your heart device.

The magnets can also shut off the monitor on a laptop if the laptop is equipped with a magnetic sensor to switch off the monitor when closing the laptop. If this happens, shut of the sensor on the laptop.

2 Safety

Tobii PCEye Go User’s manual v.2.8 - en-US

2.6 Child Safety

The Tobii PCEye Go is an advanced computer system and electronic device. As such it is composed of numerous separate, assembled parts. In the hands of a child certain of these parts have the possibility of being separated from the device, possibly constituting a choking hazard or another danger to the child.

Young children should not have access to, or the use of, the device without parental or guardian supervision.

2.7 Do not Open the Tobii PCEye Go

Non-compliance will result in loss of Warranty! There are no user serviceable components inside. Contact Tobii Dynavox Support if your Tobii PCEye Go is not working properly.

2.8 Gaze Interaction

Some people may experience a certain amount of fatigue (due to intentional eye focusing and hard concentration) or even a dryness of the eyes (due to less frequent blinking) when first getting used to Gaze Interaction. If you are experiencing fatigue or dry eyes start off slowly and limit the length of your Gaze Interaction sessions to your comfort level. Remoisturizing eye drops can be helpful to combat dryness.

Tobii PCEye Go User’s manual v.2.8 - en-US

3 Getting Started

4 Using the Tobii PCEye Go

4.1 Positioning

Figure 4.1 Positioning

The mounted Tobii PCEye Go attached to its Magnetic Mounting Plates and to your device is designed to work optimally when it is parallel to the user’s eyes at a distance from about 45 — 90 cm (18 to 35 inches) for Tobii PCEye Go, see Figure 4.1 Posi- tioning, page 14 or Figure 4.2 Positioning when Users Leaning Sideways or Those Lying Down, page 14.

Figure 4.2 Positioning when Users Leaning Sideways or Those Lying Down

This means that for those users leaning sideways or those lying down the Tobii PCEye Go with monitor and computer device also needs to be tilted in order to keep the users eyes parallel to the screen and at the optimal distance, see Figure 4.2 Position- ing when Users Leaning Sideways or Those Lying Down, page 14.

Make sure the user is placed comfortably in relation to the optimal positioning of, and distance from, the unit. Be aware also that the user’s comfort, as well as the Gaze Interaction performance, will be enhanced if the sun is not shining directly on the screen or into the user’s eyes.

The optimal distance that a user should be from the Tobii PCEye Go mounted on a monitor/laptop differs depending on the size of the screen. The user should be positioned at the optimal distance to allow for the best possible Gaze Interaction.

Generally, the larger the size of the screen, the greater the distance the user should be from the Eye Tracker / Screen combination for optimal Gaze Interaction.

Smaller than a 10 inch screen and larger than a 27 inch screen should not be used for optimal Gaze Interaction, for more information see Appendix D Technical Specifications, page 58.

4.1.1 Track Box

The Tobii PCEye Go allows for extensive Freedom of Head Movement. Once the Tobii PCEye Go is properly calibrated and placed in front of the user, no further adjustments are required.

The Tobii PCEye Go produces an industry leading sized track box with the approximate dimensions of 30 cm × 20 cm × 20 cm / 11.8 in × 7.9 in × 7.9 in (Width × Height × Depth). The Track Box is an invisible box positioned approximately 60 cm (23.5 in) straight out from a point just above the middle of the screen.

4 Using the Tobii PCEye Go

Tobii PCEye Go User’s manual v.2.8 - en-US

At 70 cm (27.5 in) the Tobii PCEye Go allows for lateral Freedom of Head Movement in an area of about 50 × 36 cm (20 × 14 in).

In order to function properly for Gaze Interaction the user needs at least one eye in the track box at all times.

4.1.2 Track Status Viewer

Use the Track Status viewer (see 4.1.2.1 Showing Track Status , page 15 for more information on how to open the Track Status viewer) to help determine the optimal height and horizontal positioning for Gaze Interaction with the Tobii PCEye Go.

• Ideally, the two dots that represent the user’s eyes should be in the middle of the Track Status viewer.

• Use the distance meter on the right hand side of the Track Status viewer to determine the optimal distance the user should be from the Tobii PCEye Go.

• The white triangle in the distance meter should hover near the center, within the green, when the optimal distance from the Tobii PCEye Go is reached.

For information about calibration of the Tobii PCEye Go see 5.2 Calibration, page 37. Also check the lighting conditions, related to what is mentioned above, when calibrating.

4.1.2.1 Showing Track Status

The track status viewer is a window/dialog where you can verify that the Gaze Interaction recognizes your eyes and that you are well positioned in front of the device.

Open the track status viewer in one of the following ways:

• Open Tobii Dynavox Gaze Interaction Settings > Calibration and select the Track status button.

• Right-click (long-hold finger on icon for touch screen right clicking) on the Tobii Dynavox Gaze Interaction Settings

icon,

, in the Notification area and select Show track status.

4.1.3 Positioning Guide

For extra assistance in positioning, there is a Positioning guide that will show itself automatically in the bottom-right corner of your monitor.

The Positioning guide is a visual guide that combines the function of the Track Status viewer with six different image based instructions to help the user with correct positioning.

Tobii PCEye Go User’s manual v.2.8 - en-US

4 Using the Tobii PCEye Go

The 6 instructions direct the user to:

1. Move head down.

2. Move head up.

3. Move head to the right.

4. Move head to the left.

5. Move head closer to the monitor.

6. Move head farther away from the monitor.

Move head closer to the monitor. Move head to the right.

The Positioning guide will automatically disappear when the user’s positioning is improved in the way that is directed by the guide.

Some users may not want the Positioning guide to pop up every time their eyes leave optimal positioning.

To turn On or Off the automatic Positioning guide, see 5.6 System Settings, page 47

4.2 Using Windows Control

Windows Control allows you to access the desktop and all applications of your Windows computer with Gaze Interaction.

4.2.1 Windows Control Type

Windows Control can be used in two different modes

• Gaze Selection Gaze Selection is a very precise and fast input method that allows you advanced Windows access but with a simple to use interface. No accidental clicks, no unintentional mouse pointer movements. You can relaxed gaze around at your Windows desktop, your software application, web page or movie, when you have decided what action you want to take next, you select your tool of choice from the toolbar and look back at the target area to make your selection.

Gaze Selection is ideal for normal to advanced Windows access where you want the full accessibility to control basically any Windows software without the need for fast decisions and movements. It can be controlled using either Gaze (dwell) or switch activation method for even more control and speed.

• Mouse Emulation

4 Using the Tobii PCEye Go

Tobii PCEye Go User’s manual v.2.8 - en-US

Mouse Emulation gives you full control of your mouse pointer, just like you would do with a physical mouse input device. You can left click, right click, double click, zoom, scroll and much more. You basically can control any Windows software that works with mouse clicks. With some practice you could achieve as high precision as with any other mouse pointer device. Mouse Emulation is ideal for emergent (sensory) to advanced Windows usage and for software which teaches the usage of eyegaze. You can hide the Mouse Emulation menu if you want to limit the functionality or avoid distraction by pressing the F2 button on your keyboard.

See http://www.tobiidynavox.com/explore/games-activities/ for ideas on some of the software and games used with Mouse Emulation.

To select which type of Windows Control you wish to use and to customize Windows Control:

• Open Tobii Dynavox Gaze Interaction Settings > Windows Control, see 5.5 Windows Control, page 44

• Select your preferred type of Windows Control under Windows Control Type

4.2.2 Starting and Disabling Windows Control

Auto start

• Open Tobii Dynavox Gaze Interaction Settings > Windows Control.

• Check the Auto start Windows control at boot check box if you want Windows Control to auto start when the Tobii Dynavox Gaze Interaction Software starts.

4.2.3 Using Gaze Selection

The Gaze Selection mode of Windows Control makes it possible for the user to control a standard Windows desktop operating system with a two step selection method which reduces the risks of unwanted clicks. It also prevents the following of the mouse cursor with your gaze as opposed to the controlling of it (there is no floating mouse cursor in Gaze Selection).

1. The first step is to select the desired Task from the docked Taskbar by looking at it.

2. The second step is to look at the desired portion of the screen (or icon on the screen) where you want to execute the Task. An automatic zoom function is enabled, ending in the selection of the icon or execution of the task.

All functions in Gaze Selection are Touch and Mouse enabled which makes it easier for a Caregiver or Assistant to help the user if needed. The Caregiver or Assistant can select a Function/Task or change the settings for the user much easier.

4.2.3.1 Gaze Selection Taskbar

At the top of the Gaze Selection Taskbar there is a Track Status viewer. It allows you to verify that the eye tracker recognizes your eyes and that you are well positioned in front of the device.

The Task Buttons in the Gaze Selection Taskbar can be in three different modes as shown in Figure 4.3 The Modes for the Gaze Selection Taskbar, page 18.

Tobii PCEye Go User’s manual v.2.8 - en-US

4 Using the Tobii PCEye Go

• Normal (Unselected) - No Task Button for Gaze Selection is chosen.

• Primary Selection (Blue/black) - The marked Task Button is selected and the Task will be executed after the automatic zoom when the user looks at the desired position on the screen or icon on it. If the selection method is set to Switch in the Gaze Selection Settings Dialog, the chosen Task Button will still remain active after executing the Task.

The Functions Overlay Task will not perform any zooming. When selecting Functions Overlay with Primary Selection, the Functions Areas/Commands will be active but not visible.

• Secondary Selection (Blue/white) - Same as Primary Selection but with a higher precision. Primary Selection means that the zoom will progress deeper before the final execution of the Task, making the desired portion of the screen bigger and easier to select within. Activate this mode by resting your gaze on the Task Button until the color changes according to the image below.

The Functions Overlay Task will not perform any zooming. When selecting Functions Overlay with Secondary Selection, the Functions will be active and the areas of each Function will be visible to the user.

In Windows 8 the colors on the Taskbar will adapt to Windows settings.

The Functions Overlay will not perform any zoom, some other tasks won't either in some situations (scroll, settings, keyboard).

4.2.3.7 Selection Methods — Gaze and Switch

There are two methods to execute the chosen Task. The method of choice is set from within the Gaze Selection Settings Dialog, see 6 Gaze Selection Settings, page 49.

Before executing a selection you select a Task from the Taskbar to execute. Gaze at your chosen task until it is highlighted as “Primary” or “Secondary Selection”.

• Gaze - To execute the chosen Task, rest your gaze at the desired portion of the screen (or icon on the screen) where you want to execute the Task. An automatic zoom function is enabled, ending in the selection of the icon or execution of the task.

• Switch - Two different execution modes.

– Single activation of the Switch - the zoom function will execute in the same way as with the Gaze method and

according to the settings made in the Gaze Selection Settings Dialog, see 6 Gaze Selection Settings, page 49.

– Activate and hold the Switch - the zoom function will zoom continuously and end only upon the release / deacti-

vation of the switch.

The Functions Overlay will not perform any zoom.

When using the Gaze method, you have to look back to the Taskbar to select a new Task after the execution of the Task, even if it is the same as you have just used.

When precision is set to zero in Gaze Selection Settings - no zoom is performed. For more information, see 6 Gaze Selection Settings, page 49.

4.2.3.7.1 Sticky Tasks & Default Left Click / Tap for Switch

When using the Switch method, a feature is made use of called "sticky tasks". If a Task becomes "sticky" it means that you do not have to look back at the Taskbar if you want to repeat the execution of the selected Task, only if you want to change the Task to another.

When using the Switch method, the Left Click / Tap Task is "sticky" by default. This means that Left Click / Tap is always on and will always be activated by the activation of the switch, if nothing else is selected. If another Task is selected it will be active only once (for one selection) and then Gaze Selection will automatically default back to Left Click / Tap for the subsequent selections.

The exception to this is the Double Click Task; when it is selected when using Switch mode it will also become sticky, meaning that it will stay selected until another Task is selected (after which it will again default back to Left Click / Tap).

This allows for excellent use cases such as quick/continual surfing of the internet by activating the Switch and thus the Left Click / Tap Task once and then repeatedly selecting anything desired, without having to choose the Left Click /Tap Task again multiple times.

4.2.3.7.2 Activating a Task with a Keyboard button instead of a Switch

Selecting the “F12 Keyboard Button”,

, on an attached keyboard will activate a Task selection. It can be used in exactly the same way as a connected switch. For more information on Switches, see 4.2.3.7 Selection Methods — Gaze and Switch, page 28.

4.2.3.8 Gaze Keyboard

By selecting the Gaze Keyboard button on the Taskbar, the Gaze Keyboard will launch as an on-screen keyboard. The Gaze Keyboard will be positioned either at the top or at the bottom of the screen depending on where the user choose to place it.

The keyboard can be placed on the screen in two different ways with the Primary and Secondary selection of the keyboard task:

• With Primary selection:

1. Activate the Primary Selection of the keyboard task.

2. Select where to write and the keyboard will be launch at the opposite side. If you want to write in the lower part of the screen, the keyboard will be placed at the top and vise versa.

With dwell usage the keyboard will be placed opposite to where you dwell immediately. If the user is using a switch, the user must first gaze where to type and then hit the switch to place the keyboard in the opposite place.

• With Secondary selection:

– The keyboard will be placed at the bottom of the screen automatically.

Together with the Gaze Keyboard, the Keyboard Taskbar will be launched. For more information, see 4.2.3.8.1 Keyboard Task- bar, page 30.

The Gaze Keyboard consists of four keyboard pages in a rotating loop. The user can easily switch between the different keyboard pages by selecting the next page buttons located to the far left and right on all pages of the Gaze Keyboard.

The key on the keyboard where the user is gazing will be indicated by a light frame around the character/function

on the

key.

The four keyboard pages are:

4 Using the Tobii PCEye Go

Figure 4.10 Second Page to the Right or Left

Figure 4.11 First Page to the Left

The Shift, Ctrl, Alt, Win and Alt Gr keys will become "sticky" once selected. This means that they will stay selected until the user selects a new key from the keyboard. They will stay sticky if the next selected key is another sticky key.

To write a letter with an accent:

1. Select the accent

2. Select the character

3. The character will appear with the chosen accent.

The Number keys in the keyboard are positioned as on a Number Pad and can be used in combination with the Alt key to write ASCII characters.

1. Select the Alt key

2. Select the number combination for the ASCII character

3. Select the Alt key

4. The ASCII character will appear.

4.2.3.8.1 Keyboard Taskbar

At the top of the Keyboard Taskbar there is a Track Status viewer the same way as in the Gaze Selection Taskbar. It allows you to verify that the eye tracker recognizes your eyes and that you are well positioned in front of the device.

The Task Buttons in the Keyboard Taskbar can be in three different modes as shown in Figure 4.12 The Modes for the Key- board Taskbar, page 31.

• Normal (Unselected) - No Task Button for Gaze Selection is chosen.

• Secondary Selection(Blue/white) - Same as Primary Selection but with a higher precision. Primary Selection means that the zoom will progress deeper before the final execution of the Task, making the desired portion of the screen bigger and easier to select within. Activate this mode by resting your gaze on the Task Button until the color changes according to the image below.

Only available for the Left Click function

Task that performs a single left-click, or for touch based devices, the equivalent of a single finger Tap.

Task that closes the keyboard.

4.2.3.8.3 Word Prediction

The word prediction engine that is used in Gaze Selection is from SwiftKey and is commonly used in tablets and smartphones. SwiftKey uses a blend of artificial intelligence technologies that enable it to predict the next word the user intends to type. SwiftKey learns from previous text the user has written and output predictions based on currently input text and what it has learned. The Word Prediction language will change depending on the Keyboard Language setting.

Figure 4.13 Keyboard with Word Prediction Activated

When Word Prediction is in use, see 6 Gaze Selection Settings, page 49 for more information about activating/deactivating Word Prediction, six (6) boxes will appear above the Keyboard. The leftmost box will display the most probable predicted word and the remaining five (5) boxes will contain one predicted word each. To select a predicted word, just select the box with the correct word in it. If you can’t find the word you are looking for, just keep on typing and hopefully the word you are looking for will appear after the next character.

Tobii PCEye Go User’s manual v.2.8 - en-US

4 Using the Tobii PCEye Go

If you are using Word Prediction and want to type a word containing an accent, like café, you are often better off letting Word Prediction handle the accent. Simply type “cafe” and you will get a suggestion for “café”.

Typing the accent manually with Word Prediction might give strange looks on the prediction buttons, but the result should come out alright in the document you are typing to.

While the user is typing, the last 5-10 characters will be displayed in blue on the indicated/highlighted key. For more information, see 6 Gaze Selection Settings, page 49. This feature assists the user in easily spotting misspellings and reduces the need for looking at the actual spot where the text is inserted, thus increasing typing speed.

4.2.3.9 Gaze Selection in Combination with Region Based Keyboards

Gaze Selection can be used in combination with other eye controlled applications. "Gaze Enabled" regions in other applications are active as long as there is no active Task in the Gaze Selection Toolbar. If you are using Gaze Selection with switch the Task Buttons will be "sticky", if you need to deselect a Task just look back at the selected Task for a short moment.

4.2.4 Using Mouse Emulation

The Mouse Emulation mode makes it possible for the user to emulate and control a standard PC mouse pointer on the screen.

To configure the Mouse Emulation, go to Tobii Dynavox Gaze Interaction Settings. For more information, see 5.5.2.2 Mouse Em-

ulation, page 45

5.2.4 Improving Calibration Point(s)

After calibration, you may want to improve one or more points.

There is a color scheme used that will help you to understand the quality of your calibration.

5 Gaze Interaction Settings

Tobii PCEye Go User’s manual v.2.8 - en-US

All three color statuses are the result of a successful calibration.

• If the background color of the Calibration Result is light red, you have achieved a successful, but relatively low quality calibration. You can improve one or more points individually, or recalibrate completely, to achieve better Gaze Interaction results.

Improving even one (or more) of the calibrations points can significantly improve the calibration.

• If the background color of the Calibration Result is light yellow, you have achieved successful and good quality calibration. You might be able achieve better Gaze Interaction results by improving one or more points individually.

• If the background color of the Calibration Result is green, you have achieved a successful and high quality calibration.

Be aware that no matter what quality of calibration you have achieved you will be able to select OK or Apply and begin using Gaze Interaction. It is the accuracy and functionality of the Gaze Interaction that is affected by the quality of the calibration results. Try for the best calibration possible.

Remember! In the end it is the personal experience that counts!

The closer the lines within the calibration point are to a dot in the center of the circle of the calibration point, the better the cali-

bration is of that point,

.You can choose the points to be improved and calibrate only those points again.

To improve one or more calibration points, follow these steps :

1. Open Gaze Interaction Settings > Calibration.

2. Select the point(s) you want to improve under Calibration Result.

3. Select the Improve Point(s) button and a calibration for the selected point(s) will start.

5.2.5 Removing Calibration Point(s)

If there is a calibration point that is consistently bad after calibration (the green lines are scattered all around and outside the circle of the calibration point) you can remove that point completely from the calibration, this may improve the calibration of the other points. Be aware that if you remove a point, that area of the screen will be uncalibrated and Gaze Interaction will not function properly there.

To remove one or more calibration points, follow these steps:

1. Open Gaze Interaction Settings > Calibration.

2. Select the point(s) you want to remove under Calibration Result.

3. Select the Remove Point(s) button.

i. Freedom of head movement describes the volume in front of the tracker in which the user must have at least one of the eyes. The numbers are

specified parallell/orthogonal to screen surface, assuming eye tracker is at 20 degree angle to screen.

ii. Gaze accuracy describes the angular average distance from the actual gaze point to the one measured by the eye tracker.

Accuracy under ideal conditions is measured with users placed in the center of the eye tracker track box with the head resting on a chin rest, and the room and screen illumination constant at 300 lux.

Accuracy across head box is measured with users after calibration systematically positioned at varying positions ranging from center of the head box up to ± 15 cm horizontal, ± 10 cm vertical and ± 10 cm distance.

Accuracy across varying background illumination is measured with users’ head resting on a chin rest, and after calibration modifying background illumination from 1 to 1000 lux.

iii. Gaze Precision describes the point-to-point variation between individual gaze samples (here specified with binocular data, ie both eyes, and

measured on artificial eyes). Gaze Precision with Stampe filter is with Stampe stage 2 noise-reduction algorithm applied to raw data (Stampe , Behavior Research Methods, Instruments & Computers 1993, 25 (2), 137-142). Precision without filter is based on raw data, without any de-noising filter applied, either inside or outside the eye tracker.

Precision under ideal conditions is measured with users placed in the center of the eye tracker track box with the head resting on a chin rest, and the room and screen illumination constant at 300 lux.

Precision across head box is measured with users after calibration systematically positioned at varying positions ranging from center of the head box up to ± 15 cm horizontal, ± 10 cm vertical and ± 10 cm distance.
