摘要:
Visual and/or audible user prompts are adaptively provided to different users of a public video phone terminal (or other data or communication terminal) on the basis of user data which is determined during a predetermined sequence of user actions and compared with stored reference data. The time from the output of a prompt to the execution of an action by the user is measured, and the number of user errors per prompt is determined. The data thus obtained is compared with reference data characteristic of an average user. A user rated as unpracticed (i.e., below average) is then given more detailed prompts than an average user, and a user rated as practiced (i.e., above average) is given fewer or no prompts.
