Ten simple pointers that can make the difference between success and failure for your touch-activated
application.
Run your application full screen. Remove title bars and menu bars so your application can take full advantage of the
entire display area.
Use bright background colors (not black). Bright backgrounds in your application will hide fingerprints and reduce
glare. Dithering or other patterned backgrounds (for example, the “crumpled paper” look) help the eye focus on the screen
image instead of reflections, even in areas where there are no icons or menu choices.
Use a simple point-and-click interface with large buttons. Dragging, double-clicks, scroll bars, drop-down
menus, multiple windows, or other elements can confuse the typical user and detract from user-friendliness and efficiency.
Turn the cursor off so your user will focus on the entire screen instead of the arrow. A cursor on the screen
makes the user think, “How do I get the arrow to do what I want?” Remove the cursor, and the user’s thinking and actions
become direct instead of indirect—thereby unlocking the true power of touchscreens.
Always give your users feedback as soon as they touch the screen. Immediate feedback is critical to reassure
the user that a touch has registered. Responses can be visual, as 3-D button effects similar to those found on a standard
Windows button. Or you can provide an audio response, such as a “click” or other sound output whenever a user touches
the screen.
Make your application fun and fast. Users will walk away from a sluggish system. You can keep their attention with a
quick response to touches. Speedy systems also reduce vandalism. Avoid graphics modes offering excessive colors or
high resolution—these will only slow down your system.
Make the application intuitive, limit choices, and guide the user as much as possible. Test your application
with users. If they pause in confusion—even for a moment—you’ve identified an area that needs improvement.
Digitized speech can talk users through your application. Because the human brain can simultaneously process a
voice and absorb an image, there is something almost magical about a user interface that provides voice prompts and
touch response. The better kiosk applications exploit this knowledge for maximum effect. For example: “Touch the first let-
ter of the company you are looking for.” Click. “Now touch OK.” Click.
Make your application part of an attractive package. Animation and large fonts help attract users to kiosk applica-
tions. The actual design of the kiosk cabinet should also be attractive and sturdy.
Keep the following in mind when designing a kiosk cabinet. Are you using forced-air ventilation? Put your fan at
the top, near the monitor’s vents. To minimize airborne dust from footsteps, keep the intake away from the floor. Keep air
from entering around the monitor’s face. Point your speakers in the direction of your user’s ears. Use an Elo Entuitive kiosk
touchmonitor—otherwise, allow for variations in the physical dimensions of monitor models, as they change frequently.
Finally, choose a kiosk finish that does not show fingerprints—avoid polished stainless steel, chrome, or glossy black
paint.
