The Role Of Visualization In Architectural Design

Today’s information and communication have become key features in any technological advancement. The situation is similar with the construction industry, where information and communication between professionals and management team are vital to the development of the industry. In this paper we focus on the role of visualization in the iterative design process as manifested through conventional methods of representation like those found in sketches and production drawings. During Idea generation in architectural design, sketch is use as a cognitive tool for idea development and adaptation; also the character and behavior of sketches make it a medium for communication and documentation during the conceptual stage of the design. In other to understand

According to [12] the sketches can be can be considered to the following characteristics; ambiguity, clarity, and design. Ambiguity means that sketching at the initial point may have less or no meaning, only the author of the sketch can have an insight of what is happening in the sketch and sometimes even the author may not fully understand the initial sketch. Clarity of the drawing is also important for presentation so as to understand and remove the ambiguity in it. The sketch product has to be the initial idea of the design all other ideas has to develop from the initial sketch design. On a general note, the process of idea generation to idea adaptation in sketching involves some iterative processes.

4.2 Sketching Activity If then sketching is an activity then what and where does it hang in the design process? Ok! As discuss earlier sketches help in seeing, communication, examination, evaluation etc. the role of sketching in design involves idea formulation and development, communication and documentation. The reorganization of ambiguity sketching is called constructive perception [12]. Idea generation activity is a crucial part of the design.

4.3 Sketching Activity as

For observing design activity, a variety of methods have been developed or adapted from those used in other fields [17]. These range from relatively informal method, such as direct observation, to retrospective methods such as interviews, questionnaires, or design diaries that take place after design activity, to real-time protocol methods which meticulously record verbal or other evidence of design activity as it takes place in [18]. The iterative feature of design is identified as a particularly interesting feature for which measurement methods are not yet sufficient to support its empirical study. The various method to measure iteration in engineering design include by character, computer software, assimilation and feedback time line, episodic and identity pattern etc. In this method of analysis the design task has to be identified and the tools for data collection and analysis must be provided. The data are to be classified based on physical action and looking action. A coding scheme has to be developing to record the number of actions of the designer during sketching activity. For the purpose of this study we want to study and see what information designer need to see between different sheets of his sketches through his looking
