Ecriture is a term used in the critical theories of Roland Barthes&sbquo Jacques Derrida and other writers in philosophy &sbquo psychoanalysis&sbquo and literature who were involved in the avant-garde magazine Tel Kel in France during the 1960s. Its original meaning in French was "writing&sbquo" but when used as a term in literary criticism it called attention to the nature of writing as a medium that serves as intermediary between the text and the reader. That is&sbquo the meaning has broadened to encompass the attempt to apprehend the very means to apprehend the subject being discussed. To put it in other words&sbquo the word ecriture is an attempt to invoke&sbquo in a conceptualization of critical methodology&sbquo a term that refers to the language (=written language) of a critical attitude that attempts to read the connectivity and structure between the "concept of product" and the "concept of text" rather than between "product" and "text." Accordingly&sbquo the possibility of applying ecriture to the language of design criticism is that by calling the concept of a "designed product" (the result of design) and the word for that concept ecriture (=written language)&sbquo the difference between "word" and "form" (that enveloped by form) becomes clear. This is a means to question design method&sbquo and we can think of it as becoming a method of thought applicable to design method and design form. For example&sbquo it can be applied as a term that is at the core of a methodology which pursues a design method dealing with the relation of mention between "form" as a formal language and "design concept" in which the formation of that form is expressed in written language comprising those two words. However&sbquo the problem is that design has not yet accepted an ecriture-like speculative theory−regarding a method of through itself that is the ecriture of design of design as ecriture−to the extent as has literature&sbquo philosophy and semiotics. We may estimate that this is because debate on the essential role and character of ecriture has not been discussed so throughly that it could be referenced by design. If that's true we can consider it indeed possible for design to develop a definition of ecriture a new display format&sbquo a meta-interface design to succeed the window metaphor. In particular a guile that would serve as a universal design is inevitable.
