Interactive displays are cost-effective once a support and maintenance network is established, because they reach a large number of people in a relatively personal way while requiring a low level of staff commitment. After construction and installation, staff commitments are relatively limited. Maintenance is always required. An agency may have professional staff accompany interactive displays to assist users. Such additional staffing requirements should be considered in the cost equation.
Interactive displays are usually independent, free-standing installations.
A television monitor is required, operated by either touching the screen or using a keyboard. Depending on the anticipated level of use, a touch screen is sturdier than most peripherals. Interactive displays are best situated in places where they will attract users. A minimal need is connection to a reliable power source for the electricity required by the monitor, the driver, and the computer. Displays are frequently linked to terminals in a central location that monitor their continued performance and reliability.
