The overall concept is the basis for the design or configuration of the interaction. The designer must pose himself two questions.

• Which interaction elements should be used?
• At which times should interaction take place?
• Which media should facilitate the interaction?

It is not possible to overly stress that the selection and application of the interaction elements should not be determined on the basis of technical or design options. Instead, dramaturgy must be the motivating factor. For example, the suspense curve and the target group definition provide definitive starting points for the design. Only dramaturgically founded design can result in effect and success.

A good example is the simplest interaction element for collective decision-making: Voting. In terms of technical or design motivation, voting is seldom insignificant. However, if voting is derived from the need and process of co-configuring the collective opinion then it is suddenly an extended tool of the interactive participant. Even the requirement for a premium-rate SMS cannot hinder this and may even reinforce it in certain circumstances.

All interaction should always be sustainable with the aid of a concrete user and a concrete scenario.

• E.g. with contents on demand. Romantics identify with a specific TV star and wish to know more about them.
• E.g. with multi-feed: Individuals who are unlucky in love wish to be rid of their inner conflict and therefore need to take an individual path through the TV programme.
• E.g. through play: School pupils wish to complete against classmates.
