Running DOS Programs from NT

RUNNING DOS PROGRAMS FROM NT

DOS mouse-driven programs run from Windows NT may also use the touchscreen when run in a window.

Limited support for Full-screen DOS mode is provided. The video mode in Windows NT and the video mode in the DOS application must be the same in order for the cursor to correctly track your finger. If the video modes are not the same the cursor will move as if out of calibration. A mouse can be used to access all programs run in full-screen DOS mode.

TIPS ON PUBLIC ACCESS TOUCHSCREEN APPLICATIONS

If your touchscreen application is used in a public access setting such as an airport kiosk, the following tips may be helpful:

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 a Windows 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.

6.Optimize the application for speed. A quick response keeps the user's attention. Users will walk away from a sluggish system. Speedy systems also reduce vandalism. Do not use a graphics mode with higher than necessary colors/resolution. It will only slow down the system. (Use of 256 colors is typically more important than resolution above 640x480.)
