Lack of Common Language
Abstract
Although participatory design theory has been widely defined and developed in last decades, evidently it has not been successful in practice. This problem has several causes. This paper attempts to illuminate fundamental one: Language. In other words, to answer the question: “What is the main reason of not succeeding Participatory Design efficiently?” it is claimed that the problem is the lack of common language between designer and user in design process. To achieve mentioned objective: First, running language among team members, especially between designer and user, is investigated. It is shown that in participatory design process, language is based on ordinary drawings, images and models, the same as un-participatory design processes. Then user’s perception of this language is called to question. It is clarified that they can not understand drawings and models; which are the words of this language. Moreover, they are not familiar with its structure; which is a conceptual model, outcome of training and experience. So, how designer and user can have an effective dialogue during design process? Finally, concluding with case study, it is shown that lack of this perception results to misunderstanding in design process between designer and user. Thus not only participatory design goals are not realized but also an integrated and harmonized design is not created.
