The biggest cost is the development of a video display. Original video footage, digitized sound, digitized data, and assembly of display components represent the bulk of the costs. Capturing original data for inclusion in the display is an additional potential cost. Agencies must consider the required pro gramming, distribution, maintenance, and downloading skills that affect cost. Hardware costs are continually dropping, due to development of compact, inexpensive technology.
Display monitors are now a relatively low-cost element of an interactive display.
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.
