The monitor should be positioned to accommodate users of many
different heights, including people in wheelchairs.
For some applications such as public information displays or video walls, you may
want to consider using a rear-projection screen and one or more LCD or DLP video
projectors.
Pointer
Mice are inappropriate for most kiosks, because the cord and position sensor are susceptible
to damage. When the kiosk application requires pointer positioning (not
always the case), a touchscreen, touchpad, or trackball are usually used.
Keyboard
Some kiosk applications require a full keyboard. Keyboards are susceptible to dirt,
abraded labels, and liquids; to deal with this, some kiosk builders use cheap keyboards
that can be replaced inexpensively, while others choose rugged keyboards
that resist liquids and can be easily cleaned. The keyboard can be mounted behind a
metal or acrylic panel cut to shape.
If your application does not require a full keyboard, you may be able to use a USB
numeric keypad instead; these are commonly marketed for use with laptops.
There are a number of companies that make custom keycaps for use with keyboards
or keypads; you can order standard sets of specialized symbols, blank keycaps (for
unused keys on the keyboard), or custom legends.
