问题     During the 1990s we will witness many technological changes in the way we communicate. Even books, like the one you are reading, will probably change from their 500-year-old format to exciting "user-friendly’ forms enhanced by the computer page. According to futurist Alvin Tofflet, books in the future will be read on book-sized video screens. These electronic devices will be able to immediately translate foreign language editions, enlarge or re duce the size of the type, change the type styles, adjust the degree of reading difficulty, and allow the readers of novels to increase or decrease the levels of violence and sexual explicitness to fit individual tastes.
   rochips or CD-ROMs (now used in libraries to deliver large amount of information to computer screens).
    Toffler has been forecasting technological changes since his first successful book, Future Shock, was published in 1970. His vision of changing trends has been remarkably accurate. In 1980, his book The Third Wave explained how civilization was in transition between the second and third great cycles of human history. The first cycle was the agrarian society, which existed until the second cycle, the industrial age, was ushered in during the late eighteenth and early nineteenth centuries. The third cycle, which is now replacing the industrial society, is the information age.
    In his latest book, Powershift, published in 1990, Toffler tells how the information explosion is causing turmoil among established institutions— such as governments, banks, trade unions and the media   as the industrial age gives way to the information age. According to Toffler, power is directly linked with knowledge and knowledge has become central to economic development. He sees a shifting of power in our culture, transforming such institu tions as finance, politics and media. These powershifts, he contends, will create a radically different society.
    In addition to economic turmoil, the information age is bringing us a wide range of new communication technologies. This technological explosion began escalating during the 1980s and seems to be gaining snowball-like momentum. Sociologist Daniel Bell pointed out that by the 1980s the United States had more people working in the production of information than in manufacturing and agriculture combined.
In its context the expression "user-friendly" means ______.
