Color naming
(1998) Şahin, Ebru
In this study, visual aspects of color and neurophysiological processes involved in the phenomenon, language of color and color models were explained in addition to the discussion of different ideas, orientations and previous works behind the subject of matter. Available color terms in Turkish language have been identified and the most frequently known or used non-basic color terms have been attained. An experimental research has been conducted to investigate the resemblance of the basic, and mostly used non-basic color terms, in the minds of the native speakers of Turkish language. Using Munsell Color System, color ranges, reflecting the color naming and color perception of Turkish Society, have been constructed for each color term investigated in the experimental research.

Composition and the uncanny : a methodological account of composition in visual arts
(2001) Ertem, Fulya
This study aims at giving an account of composition in visual arts by basing itself on the notion of uncanny. In that respect the works of three different surrealist artists, Max Ernst, Giorgio De Chirico, and Joan Miro, will be analysed in terms of their compositional uncanniness, by taking into consideration writers who analysed the uncanniness of these artists’ works. As an addition to those writers’ ideas, the aim of this thesis will be to find some new aspects of compositional uncanny in order to challenge the traditional account of composition in visual arts, as a source of visual resolution into unity.

Enforcing creativity in graphic design
(2002) Erdurak, Naciye Derin
Enforcing creativity in basic design is as important as giving students the design principles and elements. During their first year all design students are taking basic design courses in order to learn those principles and elements but starting from their first year education, creativity must also be enforced. This thesis is a research which is trying to find proper and direct ways to achieve this goal under the light of previous research and studies, with present basic design students.

A perceptional model to understand immersion
(2009) Alper, C. Armağan
The aim of this study is to offer a new model for the concept of immersion based on the process of perception in humans. The motivation behind the study is that although the concept of immersion points to an important experience both in various media and daily life, current approaches to the concept do not provide an analytical framework needed for understanding it. This study offers a cognitive and parameter based model which is based on the perception theory put forward by Henri Bergson in his book Matter and Memory. The model makes possible the analysis of the concept of immersion in terms of various cognitive and physical factors.

Perceptually driven stereoscopic camera control in 3D virtual environments
(2013) Kevinç, Elif Bengü
Depth notion and how to perceive depth have long been studied in the eld of psychology, physiology, and even art. Human visual perception enables to perceive spatial layout of the outside world by using visual depth cues. Binocular disparity among these depth cues, is based on the separation between two di erent views that are observed by two eyes. Disparity concept constitutes the base of the construction of the stereoscopic vision. Emerging technologies try to replicate binocular disparity principles in order to provide 3D illusion and stereoscopic vision. However, the complexity of applying the underlying principles of 3D perception, confronted researchers the problem of wrongly produced stereoscopic contents. It is still a great challenge to give realistic but also comfortable 3D experience. In this work, we present a camera control mechanism: a novel approach for disparity control and a model for path generation. We try to address the challenges of stereoscopic 3D production by presenting comfortable viewing experience to users. Therefore, our disparity system approaches the accommodation/convergence con- ict problem, which is the most known issue that causes visual fatigue in stereo systems, by taking objects' importance into consideration. Stereo camera parameters are calculated automatically with an optimization process. In the second part of our control mechanism, the camera path is constructed for a given 3D environment and scene elements. Moving around important regions of objects is a desired scene exploration task. In this respect, object saliencies are used for viewpoint selection around scene elements. Path structure is generated by using linked B ezier curves which assures to pass through pre-determined viewpoints. Though there is considerable amount of research found in the eld of stereo creation, we believe that approaching this problem from scene content aspect provides a uniquely promising experience. We validate our assumption with user studies in which our method and existing two other disparity control models are compared. The study results show that our method shows superior results in quality, depth, and comfort.

Photography as the writing of light
(2000) Aytaç, Olgu
The purpose of this study is to investigate certain critical approaches to photography and to try to make a re-reading of photographic images, with pursuing some of the reading strategies that French philosopher Jacques Derrida employs in deconstruction. The major aim is to point out the intrinsic features of photographic images which have been foreclosed most of the time, by the discourses established upon it and to trace a possible framework for the experience of images.

Pictorial space: a comparative account of projective versus constructivist theories of graphic perception
(1996) Anafarta, Orhan
This study aims at constructing an 'overall theoretical outline' that would structure the existing approaches to graphic perception within a comprehensible whole. In this context, two dominant theoretical paradigms, namely 'projective' and 'constructivist' arguments of pictorial perception are analysed in a comparative manner. Due to the fact that different theorists adopt these two arguments in varying degrees, 4 distinct approaches to pictorial perception are analysed extending within two extremes. The comparison is based on the phenomenon of pictorial space as a significant feature of graphic imagery.

The use of visual idea in illustrated entertainment posters and approaches in Turkey
(1994) Özkal, Özlem
The intention of this study is to examine the formation of the visual idea as a contributor to the communicative function of the illustrated entertainment posters and to evaluate Turkish entertainment posters in terms of this practice.
