13 CHAPTER 2 Customizing the software About this chapter During set up of the touch screen (Chapter 1), the performance of the touch screen was optimized. If you are satisfied with these default settings, you can skip this chapter. This chapter explains how to: Start the NFI touch screen software. Customize touch responses. Customize communication parameters of the NFI controller. Achieve right-mouse button emulation by touching the screen (Windows NT 4.0, Windows 98, and Windows 95 only). Operate a mouse and the touch screen at the same time. The instructions in this chapter pertain to the following operating systems: Windows NT 4.0, Windows 98, and Windows 95 Windows 3.1 MS-DOS If you are running your NFI touch screen with an operating system other than one of these, check for other software instructions on Windows NT 4.0, Windows 98, and Windows 95 operating systems Starting the software To start the software, do one of the following: From the Windows operating system desktop, select Start» Programs» Touch Screen Utilities» Configuration. In the NFI Setup and Diagnostic Utility dialog box, select Configuration. The Configuration Utilities dialog box appears. 9

14 MicroTouch TM Near Field Imaging TM (NFI) Software User s Guide Align the touch screen before using it. See Chapter 1. Customize touch responses. Configure the TouchSurround TM area and define the TouchSurround buttons. See Chapter 3, Chapter 4, and Chapter 5. Change controller communication parameters or sensitivity. Customizing touch responses Use the Display Area Configuration dialog box to adjust the touch responses of the touch screen. This step is necessary only if you want to change the default settings for the touch screen. 1. In the Configuration Utilities dialog box, select Display. Select the Test Box after adjusting the Double Touch Speed or Timed Double Touch sliders. The Test Box changes color when you successfully touch it. 2. Configure the options below. 3. After you ve configured the settings, select OK to save them or touch Cancel to discard the changes and revert to the previous settings. 10

15 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. 11

16 MicroTouch TM Near Field Imaging TM (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 Sets the serial communication port. Selecting a port automatically fills the Interrupt and Address boxes with the default values for the port. To use custom combinations, select the Interrupt and Address individually. 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. 12

17 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. If you decrease the sensitivity to Low, the touch screen is not as responsive but it s also less likely to detect false touches. This setting is useful when using an alignment tool or a finger without gloves. To adjust the Sensitivity slider: 1. In the Interface Configuration Options dialog box, select Sensitivity. 2. In the Sensitivity Configuration dialog box, adjust the slider to the desired setting (Table A). After you adjust the Sensitivity slider, select the Test button. 3.

20 MicroTouch TM Near Field Imaging TM (NFI) Software User s Guide Autorepeat Rate This setting is only for the TouchSurround TM 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 Check this box if you want the pointer to follow your finger around the screen until you release it.

21 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. MS-DOS operating system Be sure to connect the mouse before starting your computer, so the driver can detect the mouse when it loads. 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. You can configure the Display area TouchSurround area to support this feature Drag Autorepeat Autorepeat Holdoff (Delay) Autorepeat Interval Display area and the TouchSurround area Beep Touch event processing 17

22 MicroTouch TM Near Field Imaging TM (NFI) Software User s Guide 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 TouchSurround TM 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> where <options> is one or more of the configuration options shown in Table B. 2. Press Enter 18

23 Chapter 2: Customizing the software In Table B, characters in bold italics are the minimum entry for each option. You can use the whole word or any abbreviation that includes the minimum entry.

When autorepeat is enabled, the button will activate the first time you touch it and its press action will repeat for as long as you hold your finger on the button. When autorepeat is disabled, the button s press action activates once only, every time you touch the button. The default is /AUTOREPEAT=ON. Sets the I/O base address for the touch controller s communications port. Enables or disables touch event beeps in the display area and TouchSurround area. The default is /BEEP=OFF. Sets the touch controller s communications port. If you change the COM port from the default of 1, ensure you change the COM port setting in the NFI Setup and Diagnostic Utility (see Changing the communications parameters on page 16). Reads TouchSurround button definitions from the specified file. Enables or disables drag movement (drag-and-drop) in the display area of the touch screen. When drag is enabled, the cursor follows your finger as you move it around the touch screen. When drag is disabled, the cursor remains where you first touched the screen. The default is /DRAG=ON. Sets the period of time required for a touch to be held before it begins autorepeating. A Short duration means that you don t need to hold a touch very long before autorepeat touches are generated. A Long duration means that you must hold a touch longer to begin generating autorepeat touches. The range is 0 to 10. A value of 0 results in a continuous stream of touch events from the moment you first touch the screen, while a value of 10 results in a delay of approximately one second between the first and subsequent touch events. The default is /HOLDOFF=5. Sets the autorepeat interval that is, how quickly the autorepeat feature repeats the touch. If you set the rate to 10, holding a touch will produce rapid repeat events. If you set the rate to 0, the same touch will generate fewer repeat events in the same length of time. The range is 0 to 10. The default is /INTERVAL=5. 19

Use the Sensitivity setting 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 gloves. If you decrease the sensitivity to Low, the touch screen is not as responsive but it s also less likely to detect false touches. This setting is useful when using an alignment tool or a finger without gloves. The default is 3. Enables or disables touch event processing for both the display area and the TouchSurround TM area The default is /TOUCH=ON. Tip: Type EMOUSE /TOUCH=OFF at the command line to disable the touch screen for cleaning. You can also define a TouchSurround button to enable or disable the touch screen (see Summary of steps on page 44). Changing the communications parameters To change the installation settings, manually enter the IRQ and base settings for the touch screen driver in the autoexec.bat file to match the hardware being used. During installation, a line is added to the autoexec.bat file. Here s an example: \TOUCH\DOS\EMOUSE /COM1 To change the IRQ and base settings, replace /COM1 with: /IRQ = XX /BASE = YYY where XX is the interrupt request number for the COM port and YYY is its I/O base address (in hexadecimal). For reference, the following table lists the default COM settings. COM settings IRQ settings Base settings COM 1 4 3F8 COM 2 3 2F8 COM 3 4 3E8 COM 4 3 2E8 After changing and saving the file, restart the computer. For details about advanced COM port options, see the Readme file. 20

25 Chapter 2: Customizing the software Operating a mouse and touch screen at the same time To use a mouse at the same time as the touch screen, load the mouse driver in autoexec.bat before loading emouse.com: 1. At the command prompt, type EDIT C:\AUTOEXEC.BAT where C is the drive letter of the hard disk. 2. Move the line containing the mouse driver before the line containing emouse.com. 3. On the File menu, select Save. Alternatively, press Alt + S. 4. Restart your computer. Be sure to connect the mouse before starting your computer, so the driver can detect the mouse when it loads. 21

27 CHAPTER 3 Configuring TouchSurround TM features: Windows NT 4.0, Windows 98, and Windows 95 What is the TouchSurround underlay? The NFI touch screen system can be used with an optional TouchSurround underlay. The TouchSurround underlay allows you to use part of the touch screen to define keys, such as the ones on a keyboard. This underlay may be used in situations where the touch screen is larger than the display. Figure 1: Example of a TouchSurround underlay Aligning the TouchSurround underlay Most applications do not require the TouchSurround underlay option. Do not align the TouchSurround underlay unless a specific application calls for its use. To align the TouchSurround underlay: 1. Select the Windows Start button, point to Programs, Touch Screen Utilities, and then select Configuration. 23

28 MicroTouch TM Near Field Imaging TM (NFI) Software User s Guide 2. In the Configuration Utilities dialog box, select Alignment. 3. In the Alignment dialog box, select the Align TouchSurround TM check box. 4. Select Alignment. Be sure you are directly in front of the touch screen. Use a finger or alignment tool to align the TouchSurround underlay. An alignment tool produces a more accurate alignment. 5. To align, follow the on-screen instructions. To cancel alignment without any changes, press ESC at any time. When finished, the new alignment takes effect immediately and the Alignment dialog box reappears. 6. Test the alignment by moving the pointer around the screen with your finger. If it is satisfactory, select OK. Otherwise select Alignment and complete the procedure again. 24

29 Chapter 3: Configuring TouchSurround TM features: Windows NT 4.0, Windows 98, and Windows 95 Customizing touch responses in the TouchSurround area Use the TouchSurround Configuration dialog box to customize the touch responses of the TouchSurround buttons. This step is necessary only if you wish to change the default settings for the TouchSurround buttons. 1. In the Configuration Utilities dialog box, select TouchSurround. 2. Configure the options below. 3. After you ve configured the options, select OK to save them or select Cancel to discard the changes and revert to the previous settings. Autorepeat Rate The autorepeat rate is the rate at which repeat actions are generated when a touch is held. Use the slider to set the autorepeat rate for buttons on the TouchSurround underlay. If you set the rate to Fast, holding a touch produces rapid repeat actions. If you set the rate to Slow, the same touch generates fewer repeat actions in the same length of time. Autorepeat affects only actions generated by button presses. It does not affect actions generated by button releases. Autorepeat Delay The autorepeat delay is the amount of time the touch screen waits before generating autorepeat actions. 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. 25

30 MicroTouch TM Near Field Imaging TM (NFI) Software User s Guide Adding TouchSurround buttons Beep on Touch Select this box if you want the computer to beep whenever a TouchSurround TM button is activated by a touch or release. The beep occurs only on the first touch of the screen. The beep won t repeat if you move your finger around the display area before releasing it. You can define the size, position, activation, and function of the TouchSurround buttons, and you can define buttons as function keys, command keys, calculator keys, screen change controls, or whatever other format you require. TouchSurround buttons are inactive while you are defining buttons. They become active when you save the definitions and exit the software. Important To optimize performance of a new TouchSurround button, ensure you position the button at least 0.25 inches (6.4mm) from the edge of your product s bezel. In addition, ensure the size of the button is at least the size of your index finger s fingerprint (about 0.70 inches or 17.8mm on each side). Summary of steps To add a TouchSurround button definition do the following: 1. Set up a new button definition in the TouchSurround Button Definitions dialog box. 2. Define the new button s coordinates. 3. Define the new button s press and release actions. 4. If desired, select the autorepeat check box. 5. Test the new button definition. 26

33 Chapter 3: Configuring TouchSurround TM features: Windows NT 4.0, Windows 98, and Windows 95 Define the new button s press and release actions Button actions are performed either when the button is pressed or released. A button can either perform a command or inject a string, not both. Commands control what operations are performed when a button is activated. See Button commands on page 61. Strings are passed to the active window when the button is pressed or released. See Strings on page 62. Select the Autorepeat check box If desired, select the Autorepeat check box to enable autorepeat for the button s press action. When autorepeat is enabled, the button activates the first time you touch it and its press action repeats for as long as you hold your finger on the button. When autorepeat is disabled, the button s press action activates once only, every time you touch the button. Test the new button definition 1. When finished, do one of the following: Select OK to start a diagnostic test of the button definition. If the definition is valid, it is added to the button definition list. If the button definition is incorrect, an error message is displayed. See Fixing overlapping buttons. Select Cancel to discard the button definition. Fixing overlapping buttons 2. Repeat the above steps for each button definition. 3. When finished defining buttons, select OK in the TouchSurround Button Definitions dialog box to save the button definition(s). Buttons cannot overlap. If you define a button that overlaps an existing button, an error message appears, and the button definition is not saved. To help find the button with the conflicting coordinates, touch the TouchSurround area where you encountered the overlap. This will display the button definition information for any button defined in that area. Then either modify the original button coordinates or define a new button with new coordinates. To correct the problem, do one of the following: Select Cancel from the TouchSurround Button Definitions dialog box to clear the button definition. Define new coordinates for the button. 29
