Accessibility of computer based training systems for the visually impaired

摘要

A computer based training server (1) downloads a course player (10) an XML file (16) and a learning point action script (15) to a client. The client (2) only initially requires a browser at the start of the session. The action script (15) generates a visible HTML page (13) and a screen reader HTML page (14) derived from the content XML file (16). The screen reader page (14) is displayed with a zero frame size so that it is not visible, but is captured by a conventional screen reader for the visually impaired.
