Physical and program designs should encourage broad use, since children and some disabled people may not be able to reach or use equipment. Designs should facilitate ease of operation to encourage people without computer experience to interact with the program. The Arizona Supreme Court has developed interactive displays, called Quickcourt terminals, to assist people in understanding how to navigate through the judicial system. Key words and numbers flash in synchronization with the narration to assist users with poor reading skills. In the first year of operation, almost 24,000 Quickcourt transactions were conducted, and only a handful of users had to seek further help.
Interactive displays are often multi-lingual.
Users interact by touching the screen. Software programs allow computers and video monitors to react to touch and respond with information or questions. These programs lead a user through a great deal of available information to find a specific answer. Users find interactive displays in a variety of public places. The Arizona Quickcourt system has used locations such as shopping malls, schools, and government offices.
