Providing or revision of study content using a computer system, by only providing support content if authorization check is successful

摘要

The computer system has access to an output unit (4), an input unit (6), and a data memory (8) in which study content and corresponding support content are stored. Study content is fetched from the data memory and output to the output unit. If the user requests support via the input unit, a user authorization check is made, and if successful, the support is fetched from the memory and output on the output unit. For authorization, a code word is requested and read in. Independent claims are also included for a computer system, and for a computer program product.
