Control Panel

The Control Panel (CP) application allows configuration of the driver for touch preference. It also displays system and diagnostic information. The particular options available in the control panel vary depending on the type of touch screen connected.

To run Elo control panel in Windows XP or Vista 32-bit, go to the Windows Control Panel and double click the Elo incon. For Vista 64-bit, there are two ways to access the Elo Control Panel:

 1) Open EloControlPanel shortcut on desktop.`

 2) Open Control Panel (Classic View) -> View 32 bit Control Panel items -> Elo Control Panel

Each of the five or more tabs in the control panel are described below. Again, exact options will depend on the type of touch screen connected. There are differences for APR and Carrol Touch Ifrared ( IR ) type screens in particular.

General Tab

The General tab is displayed when the Control Panel is opened. The other tabs described below may be selected and the video alignment program EloVA may be launched from this tab.

Mode Tab

The Mode tab selects touchscreen operating mode. All selections made in the Mode tab must be activated by clicking the "Apply" button at the bottom of the dialog.

Mouse Button Emulation Mode

This mode is selected by clicking the appropriate radio button.

Click on Touch

Click on touch sends immediately upon touch a mouse down/up message at the point of touch on the touchscreen. The user's finger must be removed from the touchscreen before a new touch at any location will be recognized. The cursor or selected objects CANNOT be "dragged" on the screen in this mode.

Click on Release

Click on release sends at the time of release (untouch) a mouse down/up message at the point that the screen was last touched. Dragging across objects on the screen will not highlight or select them unless untouch occurs when the touch is over the object.

Video Alignment Mode

25 point Video Alignment (Enhanced mode) capability to achieve greater than 1% linearity.

Untouch TimeOut

· Delay setting from 0 to 1200 seconds, default is 10 seconds

Mouse Emulation (Drag and Double-click)

§ Sends a mouse down message at the point of contact.

§ Selects an object if it was at the initial point of contact.

§ Drags a selected object on the screen.

§ Response to dragging is set by the Drag delay slider bar.

§ Sends a mouse up message at the point of untouch.

§ Double-clicks on an object when the screen is touched twice in rapid succession at the same location.

§ The speed to achieve double-click is identical to the speed of a successful double-click with the mouse.

§ Double-click speed is set from the Mouse Properties control panel (Mouse Properties>Buttons>Double-click speed).

§ Double click area graphically sets the dimensions of the location around each clickable icon or object on the screen which will be recognized by Windows as a double-click. The size of the wire-frame square displayed in the Double click area tab is the actual size of double-click area accepted by Windows. The square is increased or decreased in size by touching the appropriate arrows adjacent to the square. Note that the double-click box size is independent of screen resolution and must be defined for each user.

Options

§ Options allow various features of the desktop related to the touchscreen to be configured. Each of the features selected must be activated by clicking the "Apply" button at the bottom of the tab.

§ Hide arrow mouse pointer turns off the standard mouse cursor.

§ Left-handed mouse interchanges the standard two-button mouse button assignments.

§ Show tool tray utility activates the Tool Tray utility in the Windows Task Bar. See Tool Tray for a complete description of this feature.

Note: Difference for APR type touch screen:

For APR type touch screen, there are no Video Alignment Mode selection radio buttons. There is the addition of the "Set APR Performance Preference" button that shows the following APR specific options.

The Set APR Preference dialog allows selection of touch performance to suit a particular style as described below.

Main Emphasis on fast key entry touch rate

Slows Drags are possible, fast dragging is compromised

Touch-and-Hold is disabled by default

                               Best Signature:

· Drag smoothing reduced to enable fast signature motions (APR induced jaggies are possible but they are mitigated by fast signature strokes, slower dragging causes jagged lines). 

· Ability to connect drags that stop and restart close to each other.

· Moderately fast key entry touch rate. 

NOTE: Signature size MUST be more than 15mm average character height. Big is better; tiny scrawl is affected by accuracy spec limit. Also make sure the Mouse Mode is set to "Mouse Emulation" in the Mode tab above.

                         Gaming:

· Moderately fast key entry touch rate

· Smoother dragging possible

General:

· Reasonable key entry touch rate

· Good drag capability   

· Generic drag smoothing for pleasing draw contours and continuity; may obscure small drag excursion features (smooths "jaggies" whether intended or not - APR can produce jaggies due to uncertainty when dragging slowly).

Sound Tab

The driver can be configured to generate a beep when the screen is touched. Select the Beep on touch check box to activate this feature.

By default, the beep is enabled when the driver is installed. The Tone ( frequency ) and the Duration of the beep can be adjusted by moving the appropriate slider in this tab, or by using the keyboard arrow keys. Selections or changes to the settings in this tab take effect when the "Apply" button is clicked.

Properties Tab

A Properties page will be created for each touchscreen connected and for each serial port where the touch screen driver was installed, even if that serial cable is disconnected. A number will be assigned to each Properties page that is related to the order in which controllers or ports are detected or enumerated. Each Properties page contains information for the particular touchscreen.

Properties 1

Screen information:

Windows Monitor Number is the monitor that corresponds to the "Windows Monitor" from the Windows Display Properties control panel.

Touchscreen Type is the Elo touchscreen used by its marketing name, i.e., AccuTouch for Elo's five-wire resistive touchscreen. 

Installed On indicates USB or lists the Windows COM port that a serial touchscreen is installed on.

Controller Model is the model number of the touch controller in the touch screen. It also displays the firmware revision of the controller.

Controller Status indicates either "Working properly" or reflects any errors reported from the controller.

Driver Version is the name and version number of the Elo driver attached to this touch screen.

Three additional buttons may appear near the lower part of the Properties tab. These are "Align", "Identify Monitor", and "Advanced". You must perform the Alignment process from the "Mode" tab atleast once in order for these additional buttons to appear in the "Properties" tab. See section on "Mode Tab".

1. The "Align" button, marked with this icon, will launch the video alignment process only for the monitor associated with the current Properties page. Running Alignment from the Properties page avoids the need to align all monitors in a multiple monitor application when only a single monitor alignment is desired.

Differences for APR touch screens: The Alignment procedure for APR screens uses only one target, not three.

2. The Identify Monitor button will display the Elo logo on the monitor associated with this Properties page for about one second each time this button is touched. This is usefull for multiple monitor setups.

3. The Advanced button displays the Advanced settings dialog box as shown below. This dialog box contains one or more additional tabs depending on the type of the touch screen.

Advanced Touch Tab

        Advanced page contains an Option and Right click on hold section. Option section has:

o Show right mouse button tool launches this feature for this monitor. See Right Mouse Button for a complete description of this feature.

o Disable Touch stops touch information from reaching Windows for this touchscreen. This feature may also be activated from the Tool Tray utility. Disabling touch has no effect on the operation of the standard mouse.

o Edge Acceleration Tool launches this utility for this monitor. Edge Acceleration Tool activates cursor enhancement near the edges of the Touch screen by pushing the cursor closer to the edge than the actual touch location. This allows, for example, easier activation of the Windows close box in the upper right corner, or activation of icons on the Windows tool trey. Apply to All Screen will activate the feature on all Touch screens. The Customize button launches a utility for adjusting the border and strength of the edge acceleration. See Edge Acceleration Tool for a complete description of this feature.

Advanced Beam Tab

This tab only appears for Carroll Touch IR screens. It allows for continuously monitoring of the health of the IR beams and reports any problems.

· Enable blocked beam monitoring. Enables or disables
beam health monitoring.

· Log failure message to file. Check this box to
write any future beam failure messages to a file named:
"C:\Program Files\EloTouchSystems\Diags.log"

· Time in seconds before triggering message. Number of seconds before displaying or logging an error message after a beam failure is detected. This eliminates false alarms, for example, if a user places their hand on the screen for an amount time.

· Failed beam count before reporting failure. Enter the minimum number of failed beams before a failure message is generated.

· Duration time for failed beam message. Enter the number of seconds that the failure message will be displayed on the screen. (Duration of the message). The message will repeat again if problem is not corrected.

Advanced Sound Tab

This tab only appears for those Carroll Touch screens that have a separate build in beeper. This feature can be used to provide audio feedback of touches in cases where the screen is placed at some distance from the host computer. Use this tab to configure the sound characteristics of the beeper similar to the "Sound" tab on the main page.

· Beep monitor speaker on touch. Enables/disables the internal beeper.

· Tone. Adjusts the tone of the touch beep.

· Duration. Sets the duration of the touch beep.

· Touch here to test beep sound area. Tests the current settings without changing focus away from the control panel. Click the Apply button in order for any changes to take effect.

Advanced Controller Tab

This tab only appears for Capacitive Touch screens (5020)

· Frequency Threshold. The frequency adjustment sets the touch screen driving frequency of the controller. Adjustment of this parameter may be needed when some of the external similar frequencies to the current drive frequency are being used nearby.

· Sensitivity. The sensitivity adjusts how difficult or easy it is to activate the touch screen; the lower the value is the more sensitive the sensor/controller will be. The allowable range is 10,000 to 65535 and the default is 32,768. The software displays the current sensitivity setting.

Right Click On Hold

Right Click on Hold is a new feature added in version 4.20. This feature allows new and efficient ways of creating right clicks on the touch screen without needing to run the Right Mouse Button Tool. If the user touches the screen and continues to touch, a right click is generated on the screen if the user remains within the Right click area and after the Right click delay time-out has occured. The right click delay allows the user to perform other touchscreen operations normally. When the user touches the screen and holds his finger down, an animated clock is painted at the location and continues to tick and generate a right click at the location after it completion.

· Enable right click on hold: If checked, it enables this feature for this screen, otherwise, it is disabled.

· Apply to all touchscreens: If checked, the current values are set to all touchscreens when "Apply" or "Ok" button is clicked.

· Right click delay: Defines the right click delay value in milliseconds. The right click delay allows the users to perform other touchscreen operations normally.

· Right Click Area: Touching within this area generates a right click. This area allows the user the flexibility to touch within a larger area

NOTE: Right Click On Hold feature is enabled only in "Mouse emulation" touch mode.
           When Right Click On Hold feature is turned on, Drag Delay value is set to a minimum of 25 milliseconds.
