This paper uses a narrative literary study to discuss how the science fiction prototyping method has been applied so far in different disciplines, including technology and engineering research (specifically Intelligent Environment research), foresight, futures- and business studies. Then the paper presents very similar practices in human-computer interaction, entitled as e.g. critical design, speculative design and design fiction. After that, the paper focuses on their common denominator, scenario planning and scenario design, and deliberates briefly on how the creative, future-oriented prototyping differs from them. The main contribution is to propose a conversional tool – an inter-dimensional portal – for all the involved disciplines that is aimed at uniting their forces and passion for science fiction – for the greatest benefit of all mankind.
