3M Touch Systems Proprietary Information

Chapter 2: Customizing the software

Double Touch Speed and Timed Double Touch

The NFI touch screen can detect a double touch, which is the same as doubleclicking the mouse. To generate two separate touches, touch the screen twice slowly.

To use the double touch feature do one of the following:

Touch the touch screen twice quickly as if you were double-clicking the mouse. This is the default option.

Use the Double Touch Speed slider to increase or decrease the time the touch screen allows between touches.

If you increase the speed too much, it may become difficult to generate a double touch; the touches will instead be recognized as two separate touches.

If you decrease the speed too much, what you intend to be two separate touches might instead be recognized as a double touch.

Touch the touch screen and hold it. To use this option, adjust the Timed Double Touch slider.

Use the Timed Double Touch slider to increase or decrease the time the touch screen waits before acknowledging a double touch.

If you increase the slider to Long, it takes about two seconds to generate a double touch.

If you decrease the slider to just off None, it takes about 0.2 seconds.

A timed double touch is generated on the initial touch only, not after dragging.

Beep on Touch

Select this option to have the computer beep on each first touch.

Drag and Drop

Check this box if you want the pointer to follow your finger around the screen until you release it. This allows you to select an object on the screen, drag it across the screen to a new location, and then drop it in its new position by releasing the touch.

Important

For optimal performance, do not choose drag and drop unless your application requires it.

3M Touch Systems Proprietary Information

MicroTouchTM Near Field ImagingTM (NFI) Software User’s Guide

Changing the controller communications parameters

Use the Interface Configuration Options dialog box to change the communications parameters needed to communicate with the NFI touch screen controller.

This step is necessary only if you want to change the communication settings you selected during installation.

1.In the Configuration Utilities dialog box, select Interface.

Change the sensitivity of the touch screen.

2.Configure the options below.

3.After you’ve configured the settings, select OK to save them or select Cancel to discard the changes and revert to the previous settings.

COM Port

Interrupt

Sets the interrupt request number used by the NFI touch screen controller to interrupt the operating system. If you are using a standard COM port, you should need to use only the default values in the Interrupt box.

Address

Sets the I/O base address used by the touch screen controller. If you are using a standard COM port, you should need to use only the default values in the Address box.

Sensitivity

Use the Sensitivity Configuration dialog box to change the touch sensitivity of the NFI touch screen.

This step is necessary only if you want to change the default sensitivity settings of the touch screen to allow for the way you’re touching the screen (finger, gloves, alignment tool), the mounting of the touch screen, and the surrounding environment.

3M Touch Systems Proprietary Information

Chapter 2: Customizing the software

Use the Sensitivity slider to increase or decrease the sensitivity of the touch screen.

If you increase the sensitivity to High, the touch screen is very sensitive and touches may be detected before the finger actually touches the screen. This setting is useful when wearing heavy or thick gloves.

Using right-mouse button support

You can open the same menu that would appear if you clicked an object with the right-mouse button.

To open an object’s menu:

1.Touch an object to select it. Leave your finger there.

2.Using another finger, touch the screen briefly diagonally opposite the first touch, to open the right-mouse menu.

While holding your index finger on the screen, use your middle finger to touch the screen diagonally opposite the first touch.

Note: The second touch won’t register if it is in the same horizontal or vertical plane as the first touch.

Operating a mouse and touch screen at the same time

The touch screen driver supports concurrent mouse and touch screen operation.

This allows you to use both a mouse and the touch screen.

Windows NT 4.0

Windows 98, Windows 95

To use a mouse and touch screen at the same time, install the mouse driver and then the touch screen driver. Windows NT 4.0 leaves the previous mouse driver active when the new one is installed. The next time you start Windows NT 4.0, both touch screen and mouse should operate.

Disabling the mouse driver

When you install the mouse driver, it will always be active, even if you install a different type of mouse driver later. If you unplug the mouse from your computer and restart Windows NT 4.0, the mouse driver will fail to load, resulting in an error message.

To disable the mouse driver:

1.Open the Device dialog box in the Control Panel.

2.Highlight the entry for the mouse driver.

3.Choose Startup to change its startup state to disabled.

The touch screen driver supports concurrent mouse and touch screen operation in Windows 95 and Windows 98.

To install a mouse driver:

1.Connect a mouse to your computer.

2.Select the Windows Start button » Settings » Control Panel.

3.Select Add New Hardware.

4.Select Yes, to have the Wizard detect new hardware for you. Do not select No to install a mouse driver manually.

5.Follow the on-screen instructions to install the mouse.

Once the mouse has been detected and the appropriate mouse driver installed, the mouse will operate at the same time as the touch screen.

If the Wizard does not detect your mouse, you cannot use it at the same time as the touch screen. You must use a mouse that Windows 98 or Windows 95 detects automatically, such as one by Microsoft or Logitech.

3M Touch Systems Proprietary Information

Autorepeat Rate

This setting is only for the TouchSurroundTM underlay.

Use the slider to set the autorepeat rate for buttons on the touch screen. If you set the rate to Fast, holding a touch will produce rapid repeat events. If you set the rate to Slow, the same touch will generate fewer repeat events in the same length of time.

Autorepeat affects only events generated by button presses. It does not affect events generated by button releases.

Autorepeat Delay

This setting is only for the TouchSurround underlay.

Use the slider to set the time required for a touch to be held before autorepeat mode begins. A Short delay means you don’t need to hold a touch very long before autorepeat touches are generated. A Long delay means that you must hold a touch longer to begin generating autorepeat touches.

Enable Surround Alignment

Select this check box to align the TouchSurround underlay (see “Aligning the

TouchSurround underlay” on page 33).

Enable Drag and Drop

Important

For optimal performance, do not choose dragand drop unless your application requires it.

Chapter 2: Customizing the software

Operating a mouse and touch screen at the same time

The touch screen driver supports concurrent mouse and touch screen operation in

Windows 3.1, windowed MS-DOS sessions, and full-screen MS-DOS sessions.

To use the touch screen and mouse at the same time:

1.From Program Manager, select the Notepad icon.

2.On the file menu, select Open.

3.Open autoexec.bat.

4.Move the line containing the mouse driver before the line containing emouse.com.

5.On the File menu, select Save.

6.Restart your computer.

Be sure to connect the mouse before starting your computer, so the driver can detect the mouse when it loads.

MS-DOS operating system

Aligning the touch screen

Before you can use the touch screen, you must use the NFI Setup and Diagnostic Utility dialog box to initialize and align the screen. Alignment orients and aligns the touch screen with the video display (see “MS-DOS” on page 7).

Customizing the touch screen

For most applications the default touch screen configuration is appropriate. To change the configuration, use the options in the emouse utility.

The emouse utility (emouse.com) allows the touch screen’s display area to react to finger touches as if they were the movements of a pointer driven by a singlebutton mouse. This means you can use off-the-shelf programs that require a Microsoft-compatible mouse.

To view the options, at the MS-DOS prompt, type EMOUSE /?, and then press

Enter. For details about the TouchSurround underlay, see Chapter 5 “Configuring

TouchSurround features: MS-DOS”.

During installation of the touch screen drivers and utilities, the autoexec.bat file is modified to include the following line:

C:\TOUCH\DOS\EMOUSE.COM

This line loads the emouse.com program into memory, where it stays resident.

Important

Do not remove this line from the autoexec.bat file, or you will not be able to use the touch screen with your MS-DOS applications

If you start applications from the autoexec.bat file, ensure that the emouse.com appears before you start any applications.

To configure the TouchSurroundTM area or display area for all sessions:

1.Use a text editor (such as edit.exe) to open the autoexec.bat file.

2.Add one or more of the parameters shown in Table B to the emouse.com command.

3.Save the changes.

4.Restart your computer so the changes will take effect.

Example of an autoexec.bat file

EMOUSE /BEEP=OFF /INT=3 /SENS=4 /DEFINE=C:\TOUCH\DOS\MYFILE.DEF

Include spaces as shown in this example.

In this example, emouse.com:

turns off touch event beeps ( /BEEP=OFF)

sets the touch event interval to 3 ( /INT=3)

sets the sensitivity of the touch screen to 4 ( /SENS=4)

uses button definitions from C:\TOUCH\DOS\MYFILE.DEF ( /DEFINE=C:\TOUCH\DOS\MYFILE.DEF)

To change the TouchSurround area or display area settings for the current MS-

DOS session only:

1.At the MS-DOS prompt, type EMOUSE <options>
