Interactive television is challenging since it is a multilayered system:

• Numerous perspectives: Technical, artistic, political, managerial, economic, psychological, social etc.
• Multilateral projects: Producers, broadcasters, equipment manufacturers, network operators, applications developers, developers of CA systems etc.
• Application of embedded systems: Set-top boxes, portable televisions, home network equipment etc.

An area of depth psychology, namely the analytical psychology of Carl Gustav Jung, inspired me to a new approach in the design of complex systems. Collective universal basic patterns (called Archetypes by Jung) can be considered and integrated in the creative process and development process of complex systems. I call this approach "Applied depth psychology". I maintain that it results in products with deeper emotional effects and thus leads to commercial success.

Other multilayered Multimedia systems (e.g. in public transport or in theme parks or at large-scale events) show comparable challenges.
