30 CHAPTER 4 CONFIGURING THE SOFTWARE FOR WINDOWS NT, WINDOWS 98, AND WINDOWS 95 About the software Starting the software The Near Field Imaging touch screen system s performance is optimized after you initialize and align it (see Chapter 3). To further adjust the touch screen system after setting it up, use the Configuration Utilities dialog box described in this chapter. This software customizes the touch screen s display characteristics, changes the communication parameters of the NFI controller, and configures the TouchSurround. To start the software, do one of the following: n Select the Windows Start button, point to Programs, Touch Screen Utilities, and then select Configuration. n In the Dynapro NFI Setup and Diagnostic Utility dialog box, select Configuration. n 17

31 Using the software Align the touch screen before using it. See Chapter 3. Customize touch responses. Configure the TouchSurround. See Chapter 7. Define Touch- Surround buttons. See Chapter 7. Change controller communication parameters or sensitivity. For Windows NT, all changes to configurable parameters are global. Changing them in one account causes them to be changed in all accounts. However, double touch speed is stored on a per-user basis. 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. 18 n CHAPTER 4 Configuring the software for Windows NT, Windows 98, and Windows 95

32 Double Touch Speed and Timed Double Touch The NFI touch screen can detect a double touch, which is the same as double-clicking the mouse. To generate two separate touches, touch the screen twice slowly. To use the double touch feature do one of the following: n 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. n 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. CHAPTER 4 Configuring the software for Windows NT, Windows 98, and Windows 95 n 19

33 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. 20 n CHAPTER 4 Configuring the software for Windows NT, Windows 98, and Windows 95

34 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. 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. See Table A. After you adjust the Sensitivity slider, select the Test button. 3. Select Test to confirm the settings for the Sensitivity slider. 4. Follow the on-screen instructions. CHAPTER 4 Configuring the software for Windows NT, Windows 98, and Windows 95 n 21

35 5. After you ve configured the setting, select OK to save it or select Cancel to discard the change and revert to the previous setting. Table A: Recommended sensitivity settings Method of touching the screen Bare finger/latex glove Alignment tool Cloth glove Leather glove Rubber glove Recommended setting 1 or higher 2 or higher 3 or higher 3 or higher 4 or higher 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. The second touch won t register if it is in the same horizontal or vertical plane as the first touch. 22 n CHAPTER 4 Configuring the software for Windows NT, Windows 98, and Windows 95

36 Operating a mouse and touch screen at the same time Windows NT 4.0 The Dynapro touch screen driver supports concurrent mouse and touch screen operation. This allows you to use both a mouse and the touch screen. To use a mouse and touch screen at the same time, install the mouse driver and then the touch screen driver. Windows NT leaves the previous mouse driver active when the new one is installed. The next time you start Windows NT, 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, 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. Windows 98 and Windows 95 The Dynapro touch screen driver supports concurrent mouse and touch screen operation in Windows, windowed MS-DOS sessions, and full-screen MS-DOS sessions. To install a mouse driver: 1. Connect a mouse to your computer. 2. Select the Windows Start button, then Settings, and then 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. CHAPTER 4 Configuring the software for Windows NT, Windows 98, and Windows 95 n 23

38 CHAPTER 5 CONFIGURING THE SOFTWARE FOR WINDOWS 3.1 About the software Starting the software The Near Field Imaging touch screen system s performance is optimized after you initialize and align it (see Chapter 3). To further adjust the touch screen system after setting it up, use the Touch Screen dialog box described in this chapter. This software customizes the touch screen s display characteristics and configures the TouchSurround. To start the software, do the following: n In the Windows Program Manager, open the Main group. Inside the Main group, open the Control Panel. Inside Control Panel, open Touch Screen. Define Touch- Surround buttons. See Chapter 8. Align the touch screen before using it. See Chapter 3. n 25

39 Customizing touch responses Use the Touch Screen dialog box to change the touch screen characteristics. 1. Complete the options as described below. 2. After you have configured the following options, select OK to save the settings. To return all parameters to their last configured values, select the Cancel button. The Cancel button does not undo any alignment that was performed from the Alignment button. Double Touch Sensitivity The NFI touch screen can detect a double touch, which is the same as double-clicking the mouse. To generate two separate touches, touch the screen twice slowly. Touch the touch screen twice quickly as if you were double-clicking the mouse. This is the default option. Use the Double Touch Sensitivity 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. Autorepeat Rate This setting is only for the TouchSurround. 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. 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. 26 n CHAPTER 5 Configuring the software for Windows 3.1

42 CHAPTER 6 CONFIGURING THE SOFTWARE FOR MS-DOS About the software Aligning the touch screen Configuring the touch screen The Near Field Imaging touch screen system s performance is optimized after you initialize and align it (see Chapter 3). To further adjust the touch screen system after setting it up, use the software utilities described in this chapter. This software customizes the touch screen s display characteristics, changes the communication parameters of the NFI controller, and configures the TouchSurround. Before you can use the touch screen, you must use the Dynapro NFI Setup and Diagnostic Utility dialog box to initialize and align the screen. Alignment orients and aligns the touch screen with the video display. For information about alignment, see the MS-DOS section under Aligning the touch screen on page 15. 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 single-button mouse. This means you can use offthe-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, see Chapter 9, Configuring the TouchSurround and buttons for MS-DOS. n 29

43 You can configure the Display area TouchSurround To support this feature Drag Autorepeat Autorepeat Holdoff (Delay) Autorepeat Interval Display area and the TouchSurround Beep Touch event processing 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 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: n turns off touch event beeps ( /BEEP=OFF) n sets the touch event interval to 3 ( /INT=3) n sets the sensitivity of the touch screen to 4 ( /SENS=4) n uses button definitions from C:\TOUCH\DOS\MYFILE.DEF ( /DEFINE=C:\TOUCH\DOS\MYFILE.DEF) 30 n CHAPTER 6 Configuring the software for MS-DOS

44 To change the TouchSurround 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 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. Table B: TouchSurround and display area configuration options Option /AUTOREPEAT={OFF ON} /BASE=<I/O base address> /BEEP={OFF ON} /COM1 /COM2 /COM3 /COM4 /DEFINE={filename} /DRAG={OFF ON} Description Enables or disables TouchSurround button autorepeat. 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. 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 Dynapro NFI Setup and Diagnostic Utility. See the Windows 3.1 and MS-DOS section under Initializing the touch screen on page 11. Reads TouchSurround button definitions from the specified file. Enables or disables drag movement (drag-anddrop) 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. CHAPTER 6 Configuring the software for MS-DOS n 31

45 Table B: TouchSurround and display area configuration options (Continued) Option /HOLDOFF=<duration> /INTERVAL=<interval> /IRQ=<IRQ number> /SENSIVITY={1/2/3/4/5/6} /TOUCH={OFF ON} Description 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. Sets the interrupt request line for the touch controller s communications port. 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. 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 button on the TouchSurround to enable or disable the touch screen. For details, see Summary of steps on page n CHAPTER 6 Configuring the software for MS-DOS

46 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. 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.

48 CHAPTER 7 CONFIGURING THE TOUCHSURROUND AND BUTTONS FOR WINDOWS NT, WINDOWS 98, WINDOWS 95 What is the TouchSurround? The Near Field Imaging touch screen system can be used with an optional TouchSurround underlay, which allows you to use part of the touch screen to define keys, such as the ones on a keyboard. This underlay would be used in situations where the touch screen is larger than the display. Figure 1: Example of a TouchSurround underlay n 35

49 Aligning the TouchSurround Most applications do not require the TouchSurround option. Do not align the TouchSurround unless a specific application calls for its use. To align the TouchSurround: 1. Select the Windows Start button, point to Programs, Touch Screen Utilities, and then select Configuration. 2. In the Configuration Utilities dialog box, select Alignment. 3. In the Alignment dialog box, select the Align TouchSurround check box. 36 n CHAPTER 7 Configuring the TouchSurround and buttons for Windows NT, Windows 98, Windows 95

50 4. Select Alignment. Be sure you are directly in front of the touch screen. Use a finger or alignment tool to align the TouchSurround. 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. 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. CHAPTER 7 Configuring the TouchSurround and buttons for Windows NT, Windows 98, Windows 95 n 37

51 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. 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. Beep on Touch Select this box if you want the computer to beep whenever a TouchSurround 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. Adding TouchSurround Buttons You can define the size, position, activation, and function of the buttons on the TouchSurround, 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 (6.4 mm) 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 0.5 square inches). 38 n CHAPTER 7 Configuring the TouchSurround and buttons for Windows NT, Windows 98, Windows 95

52 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. Set up a new button definition To set up a new button: 1. In the Configuration Utilities dialog box, select Buttons.

53 Define the new button s coordinates To use a new button, you must define its coordinates. The coordinates of a button s upper left and lower right corners define the button s size and its position on the TouchSurround. To ensure accuracy, use an alignment tool to define the button s coordinates. While defining a TouchSurround button, do not rest your hand anywhere on the surface of the touch screen or bezel because the presence of your hand affects the values passed to the screen. To define the button s coordinates: 1. Hold the alignment tool at a 90-degree angle to the screen s surface, and touch the Upper Left box in the Define a Button dialog box. Define the size and position of the button by touching the screen, or by entering its X and Y coordinates here, separated by a space. If you touch the screen, the coordinates are entered automatically. 40 n CHAPTER 7 Configuring the TouchSurround and buttons for Windows NT, Windows 98, Windows 95

54 2. Touch the point on the TouchSurround where you want to position the upper left corner of the new button. Align the alignment tool with the inside edges of the button s corner Correct Incorrect 3. Touch where you want to position the button s lower right corner. The coordinates of the areas you touched are displayed in the Upper Left box and Lower Right box. Define the new button s press and release actions Button actions are performed either when the button is pressed or released.
