It is interesting to note how technology has changed the way that people communicate with one another. Several of the major historical developments of communication are: (1) language; (2) alphabet; and (3) writing. These early forms of communication enabled humans to go beyond verbal and symbolic communication and on to such technologies as the printing press, telegraph, telephone, radio, television, and computers. These technologies enabled large numbers of people to communicate and exchange knowledge with one another, and masses of people. The users of these technologies used their hands and fingers to write a message, dial a number, or change a television channel. We can therefore say that there is a "tactile dimension to technology. Today we are increasingly seeing devices that require only the slightest touch of a visual screen to interact with the technology available. This is known as "touch technology." This article explains how different types of "touch technology work, and how it is being used in the retail, service, fast food, and industrial industries. Included is a discussion of ways display technology may influence the way we use and interact with computers, and other forms of media in the future. Strategies for teaching problem solving and critical-thinking skills along with assessing the impacts of technology are also provided. (Contains 8 figures.)
