Reading an interactive installation of typography " In order to control" Through Gestalt visual perception principles

“In order to control” as an interactive installation based on typography and motion that is Nota Bene –the creative and artistic group- made and presented it in years 2011 to 2015 in numerous international festival and exhibitions. This multimedia installation uses new digital media technologies combined with the human body and lets its visitors to explore in typographic space and has unique experience. Present research method is a descriptive, analytical and deductive manner, therefore studying this interaction work with the Gestalt visual rules. What is important in gestalt visual perception principles is realizing the communication perception that cause significant behavior. The purpose of this study was to discover the impact quality of gestalt visual perception rules in an interactive installation to identify its potential in creating beneficial communication. Achievement of accommodation of this theory to typographic installation showed that use them get better organized components and also makes perception work easier and logical which cause the audience to participate actively and had more interaction with other visitors and leads to communicate, exchange knowledge and experience. Moreover, despite of an effective role of designer in the implementation of gestalt principles in structure, should not be ignored varied and different pragnans of audience random acts and movements. In addition, the relationship between form and content is based on the collaborative and dynamic presence of the participants, but their collective solidarity in determining the trend and fate of the layout, which can be broadly extended to civil society, is likely to bring different and more appropriate results to Follows. The achievements of matching the present sample and Gestalt's rules showed that although the content and Raw material of the work of art were at the discretion of the artist and the perceptual principles of Gestalt were designed in advance, the dependence of the seven principles of Gestalt's visual perception on random acts, motions, and audience's decision It also should not be overlooked in the process of completing the effect, so that if the element of writing and movement are the most important components of the planned layout, the presence of the audience is certainly the most important and decisive element of the unpredictable and effective in its perceptual process, such that the transcript It has established with these rules. Also, after examining the principles of Gestalt, a general arrangement was made that the effect of each of the laws was not the same and exhibited different pregnancies, thus emphasizing one of them as the most important principle in the arrangement is difficult and unrecognizable, While the performance of these rules on the form and content can be estimated in equal proportions. Another noteworthy point in the "in order to control" is that typography is more in the service of visual aesthetics and the participants are also more externally distinct, but with all this, the title, content of the layout and general goals of the ideologists can still be matched to the visual structure.
