Interactive video displays and kiosks are similar to automatic teller machines, offering menus for interaction between a person and a computer. Information is provided through a presentation that invites viewers to ask questions or direct the flow of information. Viewers activate programs by using a touch-screen, keys, a mouse, or a trackball. Software used in interactive video displays and kiosks is highly specialized, storing information on CD-ROM or floppy disks that allow retrieval of specific information based on directions from the viewer. By contrast, hardware requirements are fairly minimal, requiring relatively simple computer equipment.
Interactive displays take advantage of evolving video and communications technologies.
The Massachusetts Turnpike Authority has installed interactive tourist information kiosks at each of its ten rest areas. During the loop presentation, viewers touch the screen to activate certain modules of information such as museums or other attractions by region or for any part of the Commonwealth. If well-sited, interactive programs reach people who do not normally attend hearings or meetings. Visual communication is very powerful, delivering large amounts of information in a relatively short period of time. Interactive displays help people understand plans and complex programs.
