Doubl e Touch Speed and Timed Double Touch

The NFI touch screen can det ect a double touch, which is the same a s doubleclicking the mouse. To generate two separate touche s, touch the screen twice slowly.

To use the double touc h fea ture do one of the following:



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

Use the Double Touch Speed slider t o incre ase or decre ase the t ime the touch screen al lo w s b et w een touches.

If you increase the speed too much, it may become difficult to generate a double touch; th e touche s will inst ead be rec ognize d as two separat e tou ches.

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 decrea se the time th e 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 sli der to just off None, it take s ab out 0.2 seconds. A timed double touch is generated on the initial touch only, not after

dragging.

Beep on Touch

Select this op tion 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 rele ase it. Thi s allows you t o select an ob ject on the screen, dra g it across the screen to a new location, and then drop it in its new position by releasing the

touch.

What is the TouchSurround underlay?

The NFI touch screen system can be used with an opt ional TouchSurround underlay. The TouchSurround underlay (illustrated in Chapter 3 on page 23) allows you to use part of the tou ch scre en to define keys, such as the ones on a keyboard. This underlay would be used in situations where the touch screen is larger th an th e display.

Aligning the TouchSurroun d underlay

Most applications do not require the TouchSurround option. Do not align the TouchSurround underlay unless a specific application calls for it s use.

To align the TouchSurround underlay:

1. At the MS-DOS prompt, type ECAL /S. Press Enter. (Note: There is a space

between ECAL and /).

2. Follo w th e on- s c r ee n in s t r u ct io n s to co mp lete the al ig n ment.

To align the Touc hSurroun d underla y, be sure you are dire ctly in front of t he unit. Use a finger or an alignment tool to align the TouchSurround underla y. An alignment tool produces a more accurate alignment.

Customizing touch responses in the TouchSurround area

Use the emouse uti lity (emouse.c om) to config ure the behavior of the display are a and the TouchSurrou nd area.

To use the emouse utility, see “MS-DOS” on page 7.

Adding TouchSurr o und button s

Using the Surround.exe utility

To define buttons on the TouchSurround area, use the Surround.exe utility. You can define the size, position, activ ation, and function of the TouchS urround buttons, and you can define buttons as function keys, command keys, calculator keys, screen change controls, or whatever other format you requi re.

Creating a TouchSurround button to disable the touch screen for cleaning

For a quick overview of the proce s s for c reating buttons on the TouchSurround area, here is an exam p le.

Cleaning the touch screen without disabling it could ca use touch events that alter your process.

To prevent this from happe ning, you could create a button called CLEAN and define its function as TOUCH. You could then press the CLEAN button be fore cleaning the screen, and press it again after cleaning to enable regular touches.

To create a TouchSur round button to disable the touch sc reen:

1. Open the Surround utility (see “Using the Surround.exe utility” on page 43).

2. Type 2 at the main menu.

3. Assign a button identifier (see “Creating the button identifier”).

4. Define the size and location of the button (see “Defining the button’s

coordinates” on page 46).

5. Define an activation method for the button (see “Defining button a ctivation”

on page 47).

6. To display the availa ble codes, type 1, and then type the number of the

TOUCH command.

7. At the main menu, type 5 to save the button definition.

8. When prompted, ente r the na me of the button definition fil e.

The default file name is C:\TOUCH\DOS\SURROUND.DEF .

9. Press Enter to use the default file name, or type the full path and file name

for your file.

Button commands and strings for TouchSurround

To add TouchSurround buttons, you must define the action when a button is pressed or released. Thi s chapter explains how to add a command or string for Windows NT 4.0, Windows 98, Windows 95, and Windows 3.1

Button commands

To define a button command:

1. Select Command.

disabled, only this button responds to touches, allowing you to reenable the screen. This function is useful for cleaning the touch screen. Cleaning the touch screen without disabling it could cause touch events that alter your proces s. To prevent this from happening, you could create a button called CLEAN and define its function as TOUCH. When cleaning the touch screen, you could then press the CLEAN but ton before cleaning the screen, and press it again after cleaning to enable regular touches.

Strings

Near Field ImagingTM (NFI) Software User’s Guide

Use the Str ing opti on t o ins ert a n ASCII string at t he curre nt cu rsor pos itio n whe n the button is activated. For example, you can define a button to behave like the Tab key on a computer keyboard by inserting the string <tab>.

Strings can be any combina tion of normal ASCII characters, special codes, modified keys, and sticky keys.



ASCII characters represent keyboard keys, includi ng alpha, numeric, and specia l ch aracte rs (se e Tab le I).



Special codes represent non-printable keyboard keys, such as Tab (see Table J and Table K).



Modified keys are creat ed by combining any ASCII charact er or special code with a Shift, Alt, or Ctrl key modifier.



Sticky keys are keys defined as the Shift, Ctrl, or Alt modifier. This applies the modifier to the next chara cter inserted.

An ASCII string can be up to 40 characters. The string consists of the first nonwhite-space ch aracter you type (leading space s ar e ignored) and all remaining characters to the end of the line ( includi n g embedded white space).

To define a string:

1. Select String.

In Windows NT 4. 0, Windows 98, and Windows 95, select String in the Define a Button dialog box.

In Windows 3.1, select the String check box in the TouchSurroundTM Area dialog box.

2. Choose a string from the fol lowing lists.

Special codes

Table J lists all the special codes that can be included in the button definition strings.



Keys preceded by the # charact er represen t number pad key s. Use the number pad keys for arithm etical fun ct ions as well—mul tip ly (*), divi de (/), subtra ct (-) and add (+).



Some codes, such as, SHIFTU, SHIFTD, CTRLU, CTRLD, ALTU and ALTD have no actual keyboa rd equivalents. They represent Shift key Up, Shift key Down, Control key Up, Control key Down, Alt key Up, and Alt key Down.



The SHIFTLOCK, ALTLOCK, AND CTRLLOCK codes represent toggle functions on each of the Sh ift, Alt, and Ctrl keys. For example, one ins ertion of SHIFTLOCK is equivalent to Shift key Down, while the next inse rtion is equivalent to Shift key Up.

CAPSLOCK applies to alphabetical keys only. SHIFTLOCK applies to all keys.

Important

Use SHIFTLOCK, ALTLOCK, and CTRLLOCK carefully. The operating system may react differently t o a mouse click plus these keys than it would to a mouse click alone.

To create a shortcut to your application:

1. While holding down the ‘Ctrl’ key on the keyboard, select an application

icon and drag it to the desktop.

2. Right mouse clic k on the icon to display options for defining properties.

3. Select the Shortcut tab.

4. Tab to, or click the Shortcut key text box.

2. Select Buttons.

3. Do one of the following:



Select Append, then define the button co-ordinates.

5. Enter the string to match what was previously entered as the shortcut key

sequence, example <C-A-A>, meaning CTRL-ALT-A.

6. Select OK.

7. Select E x it.

Sticky keys

You can also define a button to be the Shift, Ctrl, or Alt modifier that applies to the inserted char ac ter that follows the modifie r. A button defined to insert this special code is called a sticky key. Inserting such a code has no effect in itself, but the next character inserted after this one has the modifier applied to it. F or example, touching a button defined as <A-> and then touching one defined as <F4> is equivalent to typing Alt+F4.

Generally, you need sticky key codes only if your TouchSurround underlay has buttons cal led Shift, Ctrl, and Alt, in which case they should be defined a s <S->, <C->, and <A->.

Activating a button defined as <S-> and then activating one defined to insert the ASCII charact er s tring h-e-l-l-o results in the key sequence H-e-l-l-o. That is, the sticky key is applied only to the first character in the ASCII character string.
