1.3.2.1Pen Usage

Using the Pen as a Mouse

You can use the pen the same way you use a mouse or touch pad with a notebook computer. Holding the pen near the display makes a small cursor appear. Moving the pen moves the cursor.

Same as a single-click on a mouse.

Same as a double-click on a mouse.

Same as a right-click on a mouse.

Working With Files

You can open, delete, or move many files or folders at one time by selecting multiple items from a list. Using a tablet pen, hover over one item at a time and select the check box that appears to the left of each item.

To turn check boxes on:

1.Go to Folder Options.

2.Click on the View tab.

3.Under Advanced settings, select the Use check boxes to select items check box, and then click OK.

Using the Pen as a Pen

The Windows Vista handwriting recognition software makes it easy to enter text into your applications with the pen. Some applications, such as Windows Journal, allow you to write with the pen directly into the application window.

XT2 XFR Input Panel

When an application does not directly support pen input, you can use the Tablet PC Input Panel to enter text into your application. If you tap in an editable area, the Tablet PC Input Panel

icon appears. Tapping the icon makes Input Panel slide out from the edge of the display.

You can also open the Input Panel by tapping the Input Panel tab, which is docked at the edge of the screen when the Input Panel is hidden.

You can move the Input Panel tab by dragging it up or down along the edge of the screen. Then, when you tap it, the Input Panel opens at the same horizontal location on the screen that the tab appears.

Page 10 of 94

Version A00-01

DellLatitude™ XT2 XFR Service Manual

You can use the writing pad, the character pad, or the on-screen keyboard to enter text. The writing pad and the character pad convert your handwriting into typed text. The on-screen keyboard works just like a standard keyboard except that you enter text by tapping keys with your tablet pen. The following table describes the different choices for using the Input Panel.

The writing pad and character pad have a number pad, a symbol pad, and web quick keys to help you quickly and accurately enter these types of text. These quick keys are hidden when you start to write, but appear after you insert or delete your writing.

Page 11 of 94

Version A00-01

DellLatitude™ XT2 XFR Service Manual

Pen Flicks

Pen flicks enable you to use the pen to perform actions that normally require a keyboard, such as pressing <Page Up> or using the directional arrow keys. Pen flicks are quick, directional gestures. You simply quickly draw a short line in one of eight directions. When a pen flick is recognized, the XT2 XFR performs the action assigned. The image below depicts the default pen flick settings. These can be customized by going to StartControl PanelPen and Input Devices and clicking on the Flicks tab.

1.3.2.2Touch Usage

One of the key advantages of the XT2 XFR is the ability to easily switch from pen input to touch input. When you use Touch Mode, a translucent image of a computer mouse, called the touch pointer, floats beneath your finger. The touch pointer has left and right mouse buttons that you can tap with your finger. You use the area beneath the buttons to drag the touch pointer.

1.3.3Windows XP

1.3.3.1Pen Usage

Using the Pen as a Mouse

You can use the pen the same way you use a mouse or touch pad with a notebook computer. Holding the pen near the display makes a small cursor appear. Moving the pen moves the cursor.

Tapping on the screen once is the same as clicking with a mouse. A double-tap constitutes a double-click.

Right-clicking with the pen is accomplished by holding the pen tip down on the screen until a red circle surrounds the pointer as illustrated to the right. Lifting the pen from here opens up the corresponding submenu.

Right-clicking in Touch Mode is accomplished by holding your finger tip down on the screen until a red circle surrounds the pointer. This can be difficult to see as often times user's fingers cover the pointer. Lifting your finger from this point opens up the corresponding submenu.

Tablet and Pen Settings

Most of the settings for the tablet and pen are located in Control Panel under Tablet and Pen Settings. These are also accessed through Dell Control Point System Manager.

1.4XT2 XFR Settings

1.4.1Installation

The N-trig Tablet Settings applet is built into the driver package. You can either install it directly from the ResourceCD or obtain the latest version from support.dell.com. Once the file has been extracted,

Page 13 of 94

Version A00-01

DellLatitude™ XT2 XFR Service Manual

an InstallShield Wizard will walk you through the process of installing the software. The appearance of the N-trig icon is an indication of a successful installation.

1.4.2Windows™ XP vs. Windows Vista™

There is only one major difference in the N-trig applet between XP and Vista. On the Digitizer Options tab, under the Input Mode section, there is no listing for Dual Mode on the XP version. Windows XP does allow use of both pen and touch but the seamless switching capability that Vista offers is not available.

1.4.3N-trig Applet

The N-trig Tablet Settings applet is used to adjust several settings for the digitizer. Once the N-trig drivers are loaded, an icon appears in the system tray.

Hovering over the icon with your pointer displays the firmware version number. Right-clicking the icon brings up the sub menu below.

Page 14 of 94

Clicking on Properties opens up the N-trig Tablet Settings window.

There are four tabs on the N-trig Tablet Settings window:

Page 15 of 94

Version A00-01

DellLatitude™ XT2 XFR Service Manual

1.4.3.1.1 Input Mode Selection

The N-trig applet has 4 operating modes:

Pen Only — In this mode, the stylus is the only device that can be used as the input device with the N-trig digitizer. Changing from Pen Only mode to any other mode is done by clicking with an active input device on the N-trig Applet icon in the system tray. When the applet is open, select desired mode and press OK.

Touch Only — In Touch Only mode, a single finger is the only input device that can be used with the N-trig digitizer. Using the stylus is not possible. It is important to note that only a single hand contact is allowed with the digitizer for proper execution. Changing Touch Only mode into any other mode is done by tapping the N-trig Applet icon in System Tray using a finger or other active input device and choosing the desired mode. Press OK to confirm.

Auto Mode — The N-Trig digitizer is capable of detecting a stylus as well as finger touch. The purpose of Auto Mode is to allow the user intuitive toggling between the Pen Only or Touch Only modes. The default input device for Auto Mode is the stylus as long as it is in range of the tablet screen (hovering in proximity or in contact). A basic principle in Auto Mode is that stylus detection in the digitizer proximity would turn the digitizer into Pen Only mode as an overriding priority. A double-tap finger gesture on the screen (similar in style to a mouse double-click) will switch the digitizer from Pen Only mode to Touch Only mode. The system will remain in Touch Only mode as long as the stylus is out of range. Once the stylus is detected in range the system will automatically switch to Pen Only mode.

Dual Mode (Vista Only) — Dual Mode is a unique operational mode that is functional only while using the Microsoft Vista operating system. In this mode, the OS switches automatically between the available pointing device according to its internal priority and attributes.

1.4.3.1.2Touch Tuning

If you believe that the XT2 XFR's finger detection function is not working properly, a recalibration of the touch feature may be in order. To accomplish this, click the Reset button and then follow the on-screen prompts.

CAUTION: Do NOT touch the screen while touch reset is in progress.

A message indicating success or failure appears once the reset routine completes. If the result is failure, try running the diagnostics.

1.4.3.1.3Launching Diagnostics

Running the diagnostics will help determine the functionality of the digitizer. Start by clicking the Troubleshoot button. Pressing the Self Test button on the subsequent pop-up window starts the diagnostics.

1.4.3.3Multi-Touch Gestures Tab

1.4.3.3.1Gestures

Gestures are expressions made while touching the screen of your Tablet PC with two fingers. They are interpreted as user commands to the operating system or active application software. When the operating system recognizes a gesture, an icon confirming the gesture appears on the screen. This multi-touch update includes three gestures: a scroll gesture, a zoom gesture, and a two-finger doubletap gesture. Gesture features and descriptive icons shown herein are sourced by N-trig.

Page 18 of 94

Version A00-01

DellLatitude™ XT2 XFR Service Manual

Scroll Gesture

Placing two fingers on the screen and moving them horizontally or vertically generates scrolling in the direction of movement: right, left, up, or down.

Zoom Gesture

Touching the screen with two fingers and moving them together or apart generates a zoom-in or zoom-out command to the screen.

Two-Fingers Double-Tap Gesture

Tapping the screen twice with two fingers sends an operating system command that you can configure. It can be used to perform actions, such as turning the display off and disabling touch gestures (default), or run an executable program, such as one that opens Internet Explorer.

Sensitivity Setup

To adjust the sensitivity for the two-finger gestures, double-click the N-trig icon ( ) in the system tray, and tap the Multi-Touch Gestures tab. Set the sliders for each gesture as desired.

1.4.3.4About Tab

The About tab is used to find information such as the driver version and firmware revision numbers. The firmware revision number can also be obtained by hovering your pointer over the N-trig Tablet Settings icon in the system tray.

Version A00-01

DellLatitude™ XT2 XFR Service Manual

1.5 XT2 XFR Pen

Your XT2 XFR uses a specifically designed electrostatic pen or stylus for use in tablet PC mode. Instead of relying on battery power, the energy source for the stylus is magnetic energy produced by the excitation coil built into the digitizer itself. The signal from the coil is picked up by the stylus and triggers the stylus to transmit an electric field.

The transmitted electric field is sensed by a matrix of conductive lines, accurate stylus position determined using the low amplitude signals received on the vertical and horizontal conductors, and an appropriate signal is transferred to the digitizer's on-board processor.

Tips come in one color type, black. The black tips present a "harder" writing feel. The system ships with a total of two black tips. These tips are easily replaced by using the pen-tip removal tool which looks similar to an oversized pair of tweezers. This tool also ships with the XT2 XFR.

NOTE: In the event of a suspected digitizer failure, the pen tip should be examined. If the tip is damaged it needs to be replaced. This will oftentimes remedy the problem with the digitizer.

1.5.1Calibrating the Pen

The pen can function at the default calibration or at a calibration set by you or by another user. It is recommended that you use the pen only while it is calibrated to your personal calibration settings. Calibration optimizes pen performance for each user.

To calibrate the pen:

Page 20 of 94

Version A00-01

DellLatitude™ XT2 XFR Service Manual

1.Open Dell Control Point.

2.Click System Tablet Settings.

3.On the Dell Tablet Settings window, click Pen & Input then click Calibrate.

4.Follow the instructions on the screen. The calibration markers are displayed on the screen as plus signs (+). Tap the pen in the exact center of each of the calibration markers.

NOTE: Be sure to calibrate the pen for use in both portrait and landscape display orientations.

1.5.2Troubleshooting

The pen is the first component to be investigated in the event of a suspected problem with the digitizer. Verify the tip is in good shape (free of chips, excessive wear, etc.) by closely examining it. If there is any doubt, you should change out the tip with a new one or one that is known to be in good condition.

You should also verify that the touch capabilities are not affected. Switch to touch mode and see if the problem still exists. If there are no symptoms present while in touch mode, the pen tip is the most likely suspect. If the problem does persist in touch mode you should run diagnostics and take the necessary steps depending on the results.
