ABSTRACT
A large number of technical issues surround information technology. This chapter deals with only a few that are particularly relevant to disabled users in education. It looks at how far technology can compensate for disabilities, and examines general technical factors that must be taken into account in selecting appropriate hardware and software, and, for that matter, in modifying it. The chapter provides some technical problems for users and the question of hazards. Ideally, each disabled student requires information technology, probably including a microcomputer, modified to suit his or her needs. Transparent modifications are particularly valuable to disabled students in enabling them to use information technology systems normally used by able-bodied people. Hardware interface may consist of components that ensure that data is transferred without loss or to provide compatibility between devices. Technical problems also arise when hardware items are linked even if the interfaces are standard.
