3 Using the SmartNav

3.1 Head Control How-To



3.1.1 How it works
The SmartNav works by tracking infrared light reflected off the dot on your forehead, glasses, headset or TrackHAT.


3.1.2 Set-up
  1. Put on the TrackHAT or peel a dot from the sheet and place it on your forehead, bridge of your glasses, or headset microphone, etc.
  2. Place the SmartNav unit on top of your monitor or clip to the top of your laptop screen.
  3. Make sure the SmartNav unit is plugged in and the software is running.
  4. Aim the SmartNav unit at your head.
  5. First time users should select a slow to medium profile.



3.1.3 Use
  1. Sit in a comfortable position with your head facing toward the monitor about 1 arms length away from the SmartNav unit.
  2. Move the cursor from one side of the monitor to the other and back by rotating your head. Large head movements are not necessary.
  3. Once you get used to the feel of the cursor movement, try increasing your speed setting. The faster your speed setting, the less you have to move your head to move the cursor from point A to point B.
  4. Practice and get comfortable using your Hot Keys, external switch, or Dwell Clicking while moving the cursor with your head.

Important Note
The SmartNav unit MUST be able to see your dot. When deciding where to place the dot, make sure to check the line of sight between the unit and dot from all angles. Please look at the pictures below for hints on dot placement.


3.1.4 Tips and Tricks
Since there can be a small learning curve to using the SmartNav, the following tips and tricks will help get you up and going quickly.

Head Movement
You should not need to move your head much to control the cursor; by customizing the different features the SmartNAV can easily deliver a smooth and pixel precise mouse experience. The biggest thing to remember is to remain relaxed and comfortable, do not tense up and try to control the cursor; just sit back and let your small natural head movements do the work for you.

SmartNav Speed For beginning users the smoothing and speed can be decreased. Start with the speed near the middle (try a setting around 5) and set the smoothing toward the middle of the scroll bar range. Having either set too high is not usually necessary. As you become more comfortable with the SmartNav you can increase the settings, but it helps to start slow. You may also want to try decreasing your screen resolution while you are getting used to the device.

Tracking
If the SmartNav software is having trouble following your reflective dot then check the tracking tab in the SmartNAV software. Look for anything showing up besides your reflective dot. If there are other objects visible then you can use the light filtering option to remove them.

Windows Mouse Settings
More advanced users may want to take advantage of the windows mouse acceleration settings. Beginning users will want to wait until they have more experience since too much acceleration may cause the cursor to 'swim' around.

The Windows settings which affect cursor movement are found under the "Mouse Settings" area in the Windows Control Panel. The precision can be increased by turning on "Mouse Acceleration" or Increasing the "Pointer Accuracy" (the name for the setting depends on the version of Windows). Also try turning up the speed in the Mouse Settings to about 3/4 and then lowering the speed setting in the SmartNav software, this can improve cursor movement on some systems.

Using Hats
Using a hat with a large reflective dot placed on the end of the brim will increase precision by a factor of 2X. The brim of the hat travels a greater distance when you rotate your head than your forehead does, creating more movement for the SmartNav software to use.

Key Activated Mode Key Activated mode with Key Release Clicking is a very convenient way of using the SmartNav. If you assign the Move action to your CapsLock key then you can simply press this key to engage your mouse control and let up over the item you want to select, then press down again to double click (or drag). This setting, along with other useful hotkeys like "Pause" and "Precision" are located in the Behavior tab of the SmartNAV software.

Gravity
Gravity is a great feature included with the SmartNAV software and should be tried out. Try having it turned on for just "Buttons", it will make the "Control Boxes" (Close, Minimize and Maximize) easier to click on. Once you get comfortable with gravity, you can add more buttons in.


3.1.5 Cursor Modes
There are two different ways to control the cursor using the SmartNAV, which allows users to choose the mode that feels the most natural.

Relative Mode
This is the easiest cursor control mode for a new user to get used to. It works in the same kind of way that a regular mouse does, bumping the cursor against the edge of the screen allows the user to change the relationship between their head position and the location of the cursor on the screen. Pressing the Center Hotkey will re-center the cursor on the screen.

Absolute Mode
Absolute mode is intended for advanced SmartNAV users, and allows a fixed relationship to be set up between the head location and the cursor position. Bumping the cursor against the edges of the screen will not change the relationship of the cursor to the users head position. Pressing the Center Hotkey will reset the relationship and re-center the cursor on the screen. Therefore, the user should make sure that their head is positioned where they wish the new center to be when they re-center.


3.1.6 Clicking
The SmartNAV provides three different methods for clicking within Windows.

Hotkey Clicking
The SmartNAV software allows the user to re-map keys from their keyboard and assign them to emulate the Left, Right and Middle mouse buttons. This provides a convenient way to click without having to take your hands off the keyboard.

SmartNAV software versions 3.20.025 and higher support using modifiers with non-clicking hotkeys, you can add modifier keys such as Ctrl+Z or Alt+Z to hotkey commands.

Please note that it is no longer possible to map just a modifier key to a hotkey function. The reason for this is so that they must not not be "trapped" and so that they can continue to function as modifier keys in other applications.

Ability Switch Clicking
(only available on SmartNAV EG and AT models)
Ability switches provide an alternative clicking method that can be operated by hand, foot or sip-and-puff switches. On the back (SmartNav 4) or side (SmartNav 3) of the SmartNav there is an industry standard Ability Switch jack which allows users to plug Ability Switches in to perform various actions. By default the switches are mapped to emulate the Left and Right mouse buttons, but may be configured to perform other functions related to the SmartNAV software such as Middle Click, Pause, Scroll or Precision Mode.

Dwell Clicking
(only available on SmartNAV AT models)
Dwell Clicking is a complete hands-free clicking method which allows the user to send clicks by simply holding the cursor still over the item they wish to click on. The Dwell Clicking software is a complete package which allows the user to perform all of the tasks that can be accomplished with a mouse, such as Left Click, Double Click, Right Click and Drag.

Voice Clicking
(Available on All SmartNAV models)
Voice activated clicking allows you to issue mouse clicks and commands by speaking to your computer. Simply say 'left click' and a left click will be performed. This powerful feature makes the SmartNAV more intuitive to use than ever and does not come with any other hands free mouse package, we hope you enjoy using it!

Remember when changing the speech commands to only change text outside of quotes. Do not change the order of items, the text in quotes "" or their IDs.

Please let us know if you have any problems.

Note :
Do not plug the microphone in to the jack on the SmartNAV. The input jack on the SmartNAV device is for input switches, not microphones.

Please see sections 2.3.6 (Voice Clicking Installation) and 4.2.3 (Clicking Tab) for details about how to enable speech recognition if it is not running.


3.1.7 Suggested Alternate Dot Placements
There are many different locations where the reflective dot can be placed for tracking, here are two examples.

SmartNAV Placement Head SmartNAV Placement Glasses


3.1.8 Status LED indicators
The SmartNAV camera has status LEDs which give the user visual cues about the status of the SmartNAV software. There are two Status LEDs, one is located on the front directly above the infrared shield, and the other is on the underside of the SmartNAV camera which will cause the case to "glow" blue when it is illuminated. Use the following key to interpret what the state and color of the status LEDs mean.

Front Status LED
  • Off : No object is being tracked, and cursor movement is NOT paused.
  • Green : An object is being tracked, and cursor movement is NOT paused.
  • Orange : An object is being tracked, and cursor movement IS paused.
  • Red : No object is being tracked, and cursor movement IS paused.

Case Status LED (SmartNav 3 models only)
  • Off : The software is operating in Relative cursor positioning mode.
  • Glowing Blue : The software is operating in Absolute cursor positioning mode.

The Save button saves the profile currently listed in the Active Profile text box.

Delete
This button deletes the profile currently selected in the profile list.

Defaults
This button will restore the selected profile to the default profile settings.

About
This button displays the version and build information about the SmartNav software.

4.2.2 Movement Tab
This panel adjusts settings which affect how the cursor moves.

SmartNAV Control Panel : Movement Tab

Horizontal Speed slider bar
Use this bar to customize your speed values. The further the bar is moved to the right, the less head movement is necessary to move the cursor on the X axis. Any adjustments you make to this setting will be stored under the profile that is loaded when you quit the SmartNav program.

Vertical Speed slider bar
Use this bar to customize your speed values. The further the bar is moved to the right, the less head movement is necessary to move the cursor on the Y axis. Any adjustments you make to this setting will be stored under the profile that is loaded when you quit the SmartNav program.

Link check box
When this box is checked, the X and Y axis are locked together and the Speed sliders affect the X and Y axis simultaneously.

Motion slider bar
This bar controls the degree of head movement that the system will filter out. In environments such as a car or airplane where a fair amount of unintentional movement is unavoidable, it may be desirable to move this bar further to the right.

Positioning
There are two different ways to control the cursor using the SmartNAV, which allows users to choose the mode that feels the most natural.

Relative
This is the easiest cursor control mode for a new user to get used to. It works in the same kind of way that a regular mouse does, bumping the cursor against the edge of the screen allows the user to change the relationship between their head position and the location of the cursor on the screen. Pressing the Center Hotkey will re-center the cursor on the screen.

Absolute
Absolute mode is intended for advanced SmartNAV users, and allows a fixed relationship to be set up between the head location and the cursor position. Bumping the cursor against the edges of the screen will not change the relationship of the cursor to the users head position. Pressing the Center Hotkey will reset the relationship and re-center the cursor on the screen. Therefore, the user should make sure that their head is positioned where they wish the new center to be when they re-center.


Invert Movement
Invert Movement check boxes: These allow you to invert Horizontal (X) and Vertical (Y) axis movement.

Camera Rotation
This menu allows you to choose the correct rotation of the SmartNav unit if you have clipped the unit to any part of your laptop screen. To ensure that the proper rotation has been selected, compare the angle of your SmartNav unit to the graphic shown in this menu.

If the SmartNav is upright (sitting on its stand), then the rotation should be set to 0. If the unit is positioned on its left or right side or is upside down, then the Camera Rotation should be set to 90, 270 or 180 degrees respectively.

4.2.3 Clicking Tab
This panel adjusts the clicking settings.

SmartNAV Control Panel : Clicking Tab

Hotkeys
The SmartNAV software allows the user to re-map keys from their keyboard and assign them to emulate the Left, Right and Middle mouse buttons. This provides a convenient way to click without having to take your hands off the keyboard. The action for each Hotkey is listed along with the currently assigned keyboard key, whether it is enabled (On/Off) and whether Sticky is enabled.

Left Click
Emulates a left mouse button, it can be used to perform Left Clicks, Double Clicks and Dragging.

Right Click
Emulates a right mouse button, it can be used to perform Right Clicks.

Middle Click
Emulates the middle button of a 3 button mouse.

Enable checkboxes
These turn the Hotkeys On and Off.

Note :
Hotkeys will only work while the SmartNAV software is running. Keyboard keys assigned to Hotkeys will not perform their normal keyboard function while they are being used as Hotkeys. For example, if the CAPS LOCK keyboard key is assigned to Left Click, it will only perform Left Clicks while the SmartNAV software is running. It will resume performing the normal CAPS LOCK function when the SmartNAV software is closed, or if the Hotkey is re-assigned or disabled.

Change buttons
Clicking these buttons brings up a dialog box that allows the user to change the key assigned to the function listed next to the button. Note that you can only assign keyboard keys to as Hotkeys.

Sticky checkboxes
The Sticky feature makes Hotkeys easier to use if a user is having difficulty pressing and holding the keys. It changes the way the Hotkey works such that pressing the key once turns the associated hotkey feature on, and pressing the Hotkey again turns the feature back off. For example, turning Sticky on for the Left Click hotkey would allow the user to send a Left Mouse Down with the first keypress, and a Left Mouse Up with the next keypress.

Ability Switches
(only available on SmartNAV EG and AT models)
Ability switches provide an alternative clicking method that can be operated by hand, foot or sip-and-puff switches. On the back (SmartNav 4) or side (SmartNav 3) of the SmartNav there is an industry standard Ability Switch jack which allows users to plug Ability Switches in to perform various actions. By default the switches are mapped to emulate the Left and Right mouse buttons, but may be configured to perform other functions related to the SmartNAV software such as Middle Click, Pause, Scroll or Precision Mode.

A Y-split adapter is included with the SmartNAV EG and AT models to allow two single action (mono) Ability Switches to be used. A dual action switch with two buttons and a stereo cable can be plugged directly into the back (SmartNav 4) or side (SmartNav 3) of the SmartNav without using the Y-Split adapter.

Left & Right
Use the drop-down menus to select the action that the ability switch will perform when it is activated.

Sticky
The Sticky feature changes the way the Ability Switches work such that activating the switch once turns the assigned action on, and activating the switch the Hotkey again turns the assigned action back off.


Show Dwell Clicking Toolbar
(SmartNAV AT users only)
When selected the Dwell Click toolbar will be enabled, this enables the dwell clicking functionality.

Double Click Assist
When this box is checked a small pause will be inserted after single-left clicks to make it easier for the user to double-click. This works with left clicks issued by both the Hotkeys and Ability Switches.


Enable Voice Recognition
To enable speech recognition for the SmartNAV software; go to the 'Clicking' tab and check the box titled 'Use speech recognition for clicking and hotkeys'. This will enable the voice recognition functionality. If you receive an error, please see the Chapter 9 (Trouble Shooting Section). If you receive no error, then the speech recognition engine has been engaged successfully, plug in your microphone and get clicking!

Enable
This checkbox turns the Hotkey on and off.

Note :
Hotkeys will only work while the SmartNAV software is running. Keyboard keys assigned to Hotkeys will not perform their normal keyboard function while they are being used as Hotkeys. For example, if the CAPS LOCK keyboard key is assigned to Pause, it will only perform the Pause function while the SmartNAV software is running. It will resume performing the normal CAPS LOCK function when the SmartNAV software is closed, or if the Hotkey is re-assigned or disabled.

Sticky
The Sticky feature makes Hotkeys easier to use if a user is having difficulty pressing and holding the keys. It changes the way the Hotkey works such that pressing the key once turns the associated hotkey feature on, and pressing the Hotkey again turns the feature back off.

Key Activated
The Key Activated Feature prevents the cursor from moving unless the Move Key is pressed and held down. The Move Key (F12) takes the place of the Center Key while Key Activated is in use.

Start At Center
This feature also only works when Key Activated is in use. It automatically centers the cursor whenever cursor movement is initiated. To use this function, check the Key Activated clicking box and then check the Start At Center box

Click On Release
This feature only works when Key Activated is in use. It allows you to initiate cursor movement and Left Click with the same key. When this feature is active, simply depress the center/move key to move the cursor to the desired icon or button and let off to click. To double click, let off, then press down and let off again. To use this function, check the Key Activated box and the Click On Release box.

Mouse Override Delay
The Mouse Override Delay Slider Bar controls how long cursor control is released to the Mouse when the SmartNav detects that the Mouse is being moved. The setting range is from 0-10 seconds.

Pause While Typing Delay
The Pause While Typing Delay Slider Bar controls how long the cursor will pause after you have stopped pressing keys on the keyboard (typing). A higher setting is helpful if you have limited head movement or are not familiar with the keyboard layout.

4.2.5 Gravity Tab
This panel adjusts settings which affect the cursor Gravity feature.

SmartNAV Control Panel : Gravity Tab

The Gravity feature helps you click on hard to hit icons and check boxes by snapping and optionally stick the cursor to them.
Use Cursor Gravity checkbox
This checkbox turns cursor gravity on and off.
When this feature is turned on, the cursor will snap to the center of whatever icon or button you are trying to hit after you have held the cursor over it long enough. If the Stick duration is greater than 0 seconds, then the cursor will briefly remain stuck to the center after snapping.

Gravity Options
These checkboxes allow you to designate which objects (Windows controls) you want the Gravity feature to work with. If you only want Gravity to work with some objects and ignore others, uncheck the appropriate boxes.

  • Menus
  • List items


Time Until Snap
This slider bar adjusts the amount of time that the cursor must be held over a windows object before the cursor will snap to it. The time is adjustable from 0-1 second. A shorter time will make it easier to activate, while a longer time will reduce the chance of accidentally activating the feature.

Stick Duration Time
This slider bar determines how long the cursor will stick to a particular object after it has snapped before allowing cursor movement again. Time is adjustable from 0-2 seconds.

4.2.6 Tracking Tab
This panel adjusts settings which affect the cursor Tracking.

SmartNAV Control Panel : Tracking Tab

Camera View window
This window shows what the SmartNav camera is currently seeing. The color of the objects in the window indicates what they mean.

  • A Green object indicates that the object is active and being used to control the cursor.
  • Grey objects indicate light sources which are detected but are not being tracked.

You can also use this feature to check for background interference. If more than one object appears on the screen, check the background for strong direct lighting or glare. Adjust the position of the SmartNav unit or room conditions if cursor behavior becomes erratic. Adjust the Light Filter level if strong lighting is a problem. Avoid positioning the camera such that it looks directly at windows, sunlight or indoor lights. The greater the number of objects seen in the camera view, the more likely it will be that an incorrect object could be picked by the software to do cursor control.

Use this window to help align the SmartNav, adjust the SmartNAV camera until the green dot (the reflective dot on your head) is near the middle of the black background.

Camera LED's On
This checkbox turns on or off the SmartNAV camera's internal Infrared LED's. This box is checked by default.

Greyscale Tracking Mode
This checkbox turns on or off a tracking mode in SmartNav 4 cameras which can provide additional cursor precision. Enabling this mode requires more USB bandwidth and may interfere with devices such as webcams. This mode should not be used when large, bright objects (such as windows) can be seen by the SmartNav.

Light Filtering
Use this Checkbox to enable or disable the slider bar which controls the filtering.

Light Filtering Slider
This slider bar is used to control the light filtering of the SmartNAV camera. A higher setting will result in more light being filtered. If used outside, the slider may need to be set to a higher value to filter sunlight. When used inside, a value of 130 should produce good results (or just un-check the Sunlight Filter checkbox). Increasing this setting above 200 may reduce the precision of the cursor movement.



4.3 Dwell Clicking

The concept behind dwell clicking is to allow total hands free control of a computer using only the SmartNAV head pointing device. This section will outline how to use the dwell click option available with our SmartNAV AT model to perform mouse click operations. When this feature is active, holding the cursor still for a user defined amount of time .2-2 seconds, will produce a Left Click, Double Click, Drag and Drop, or Right Click.

(Please note that Dwell Clicking is only available with the SmartNAV AT model)

4.3.1 Enabling Dwell Clicking

To use this feature, enable the Show Dwell Clicking Toolbar checkbox on Quick Access Panel

Enable Dwell Click from Quick Access Panel

Or from the Clicking Tab of the Control Panel, enable the Show Dwell Clicking Toolbar checkbox.

Enable Dwell Click from Control Panel

When Dwell Clicking is turned on, a bar with eight buttons will appear at the top of your screen. This bar gives you the option to; Pause Dwell Clicking, Single Left Click, Double Left Click, Drag and Drop, Right Click, change Dwell Clicking options, Close Dwell Clicking, and move/drag the Dwell Clicking button/tool bar to another location.

4.3.2 How to Select and Perform a Click

Dwell Clicking button bar color key

SmartNAV Dwell Clicking Toolbar Color Key

Unselected
The type of mouse click represented by this button has not been selected as either the default or a single use action.

Dashed
The type of mouse click represented by this button has been selected for a single use action.

Highlighted
The type of mouse click represented by this button has been selected as the default action.


Highlighted vs. Dashed
When you start the Dwell Clicking application for the first time, you will notice that the Single Left Click button is Highlighted blue. This indicates that Single Left Click is the default function. When you dwell on an object with this Single Left Click button highlighted, the system will produce a Single Left Click.

Each type of mouse click represented on the Dwell Clicking button bar can be made the default action for continuous use.

If you would like to perform a type of mouse click only once, and then have the Dwell clicker go back to the default action you can select a button to be the action for one time only. This is useful for example if you want to drag and drop something only once, then go back to doing normal single left clicks. To select a button for one time only use move the cursor to the button that corresponds to the mouse click you wish to perform and rest the cursor on it for a moment. When clicked once, a Dashed line will appear around the button, this button is now selected for single use. After this mouse click is completed, the system will revert back to whichever mouse click is default or 'Highlighted' blue.

If the button is clicked on a second time, the button will become highlighted blue and the selected type of mouse click will now be your default action.

Selecting the Type of Mouse Click
To select what kind of mouse click to perform move the cursor to the button that corresponds to the type of click you wish to perform and rest the cursor on it for a moment. If a dashed line is around the button it will be the single action, if the button is highlighted blue it will be the default action.

The available types of mouse clicks and their associated button icons are listed below:

Pause button
The button furthest to the left of the toolbar pauses and un-pauses Dwell. When this button displays green, Dwell Clicking is active. When it displays red, Dwell Clicking is paused. Even if Dwell Clicking is paused, it can still be un-paused by simply dwelling on the red circle.

SmartNAV Dwell Clicking Toolbar Active Paused State

Single Left Click button
The second button in the dwell clicking toolbar looks like a single cursor arrow. This button is used for single left clicking.

When this button has a dashed line around it, the system will single click the next time you dwell on an object then go back to the default (highlighted) button. When this button appears highlighted blue, it is the default action and you may single click continuously without highlighting the button each time.

Please note that this behavior is the same for all mouse click buttons on the dwell toolbar.

SmartNAV Dwell Clicking Toolbar Single Click


Double Click button
The third button on the dwell clicking toolbar is the Double Click Button and looks like two overlapped cursor arrows, and is used for double clicking.

Drag button
The fourth button looks like a cursor arrow connected to three dots, and is used for dragging and dropping. This type of mouse click works great for playing games like Solitaire.

Click Time slider bar
This slider bar adjusts your dwell click time, or the amount of time you must hold still before the software will produce a click. This time can be adjusted from .2 seconds with the bar moved all the way to the left of the bar, or 2 seconds if the bar is moved all the way to the right side. Click time is also shown graphically in a green bar to the right of the Click Time slider bar.

Movement Threshold slider bar
This slider bar allows you to adjust the Movement Threshold from 2 pixels to 20 pixels. This is the amount of movement that the system will ignore while you hold the cursor still. Move the slider bar marked Movement Threshold to the left to decrease the amount of movement that the system will ignore. Move it to the right to increase the amount of movement the system will ignore. The Movement Threshold is also shown as a red target to the right of the Movement Threshold slider bar.

Use this menu to change the size of the Dwell Clicking button bar.

Float Over Windows
The difference between On and Always On is that when set to 'On' the dwell software will set itself to be at the top of the window stack.

With 'Always On' the dwell software will set itself to be at the top of the window stack and then check back every 60 seconds to make sure it is still at the top, and if not, will re-assert itself.

The 'Off' setting will allow the dwell toolbar to be put behind windows and will not stay on top, useful for users who only need one mouse function.

Click Sound check box
When this box is checked, the system will produce a clicking sound when ever a Dwell Click is registered.

Close Button

5 Accessories
There are several accessories available for your SmartNav unit that are intended to give you more options for cursor control and clicking based on your needs and preferences.

5.1 External Ability Switches
(Only available on SmartNAV EG and AT models)
The Ability Switches allow the user to perform clicking and other functions through the use of hand, foot or sip-and-puff operated switches. The switches are sold separately from the SmartNAV device.

How they work
The SmartNav EG and AT models include a functional stereo Ability Switch jack for built into the back (SmartNav 4) or side (SmartNav 3) of the SmartNav, and a Y-split adapter for connecting two single (mono) switches at once. These switches can be used to perform all normal Hot Key functions.

Set-Up
  1. If open, shut down the SmartNav software.
  2. If using two single (mono) switches, securely plug the Y-split adapter into the SmartNav's stereo Ability Switch jack.
  3. Plug the cable(s) from switch(es) into the jack(s) and place switches in the desired location.
  4. Open the SmartNav software and place a dot on your forehead. Move your head to ensure that the SmartNav unit is tracking the dot properly. Click each switch several times to determine which switch is the one Right and which is the Left.

Use
After determining which is the Right switch and which is the Left switch, experiment with switch placement to determine your optimal set-up. The SmartNav Ability Switch jack and Y-split adapter will work with most switches. So if you already have a switch you like, feel free to try it with the SmartNav.

Switch clicking does not interfere with the SmartNav's other clicking methods. All clicking methods can be used at the same time.

5.2 Rings

How it works
Using the SmartNav Ring you can control your computer's cursor by pointing your finger toward any location on your monitor.

Set-Up
  1. Place the ring on your right index finger if you plan to use your left hand to hit the Hot Keys. Place the ring on your left index finger if you plan to use your right hand to hit the Hot Keys.
  2. The ring should be placed halfway between the first and second knuckles of your index finger.
  3. Place the unit on top of your monitor or clip the unit to the top of your laptop screen and aim it at the keyboard. OR clip the unit to the side of your laptop screen and select 90 degree rotation from the Advanced Settings menu (described in section 2.4) if the unit is clipped to the right side of the screen, or 270 degrees rotation if the unit is clipped to the left side of the screen. The unit can also be placed in front of your keyboard.
  4. Place your ring hand on the keyboard and use your other hand to adjust the SmartNav unit. Adjust the unit until the green indicator light comes on when your ring finger is lifted slightly above the keyboard.

Use
Raise your finger slightly off the keyboard until the cursor begins to move. Move your finger slowly from side to side and up and down to get used to the feel of the cursor movement.

Once you get used to the feel of the cursor movement, try increasing your speed setting. The faster your speed setting, the less you have to move your finger to move the cursor from point A to point B. If you have difficulty moving the cursor to the top, bottom, or either side of the screen, raise your finger slightly off the keyboard and press the center key.

Note: It is advisable to use the Data Window to properly align the SmartNav unit with your finger.

SmartNAV Camera



9.15 Problem : Voice Clicking software is properly installed, but Voice Commands are still not being recognized

Possible Cause
Issue with Microphone, or Soundcard Settings in Windows

Solution

Once you have verified the latest version of the SmartNAV software has been installed and the voice recognition engine has also been installed, and if you are still having problems here are a few things to try:
 
  • Verify that the microphone is correctly plugged into the microphone input of the sound card.
     
  • Verify that the sound card is correctly installed and configured. You can test this with another application that uses sound input like the Sound Recorder program which should already be installed with the Microsoft Windows operating system.
     
  • You can open the Sound Recorder application from the Start menu. On the taskbar, click Start, then All Programs, then Accessories, then Entertainment (or Multimedia, depending upon the version of Microsoft Windows) and finally, Sound Recorder. When the application window has opened, click the Record button and speak into the microphone. The display in the window should now move in response to your voice input.
     
  • If the Sound Recorder application doesn't record your voice correctly, open the ‘Volume Control’ and verify the ‘Microphone In’ is not muted. If this does not help then the sound card may not be compatible you’re your version of Microsoft Windows, it may not be set up correctly, there may be a problem with its software drivers or some other cause. These errors should be corrected before you continue on with the other troubleshooting suggestions. Contact the sound card manufacturer's technical support for assistance, if necessary.
