Chapter 3 - Using MonitorMouse for OS/2
window is maximized, you may touch the upper-right corner to restore the
window, touch the top to click on the window title, and double-tap the upper-left
corner to close the window.
Option Buttons and Check Boxes
It is easier to select an option by touching the option name rather than touching the
option button. The same is true with check boxes.
Choosing the Control-Menu, Minimize, Maximize, and Restore
Buttons
Windows can be maximized and restored easily by double-tapping the title bar as
described above. The Minimize, Maximize, and Restore buttons, and the Control-
menu box can be difficult to touch as they are quite small on high-resolution
screens. Since they all act on button release, you can slide among them before
selecting as with the drop-down menus. You can also use the Control menu to
easily maximize, minimize, restore, and close windows.

1.
Run the application full screen. Do not have a title bar, menu bar, etc.
2.
Use bright background colors (never black) to hide fingerprints and reduce
glare. A patterned background, such as dithering, will also help the eye focus
on the image rather than reflections, especially in background areas where there
are no icons or menu choices. Fingerprints make a system look dirty and
unattractive.
3.
Use a simple point-and-click interface with large buttons. Do not use dragging,
double clicks, scroll bars, drop-down menus, multiple windows, etc.
4.
Turn off the cursor. Users will focus on the entire screen instead of the arrow.
The presence of a cursor makes the user subconsciously think "how do I get the
arrow to do what I want?" By removing the cursor, the user's thinking/action is
direct instead of indirect, unlocking the true power of touchscreens.
5.
Always give feedback to the user instantly on touch. A 3-D button effect works
well (such as an OS/2 standard button). Output a click sound, etc. Clear the
screen while searching for the next screen. Use an hourglass. Immediate
feedback is necessary because the touchscreen has no tactile feedback
mechanism.
