A comparative study on spatial perception in real and virtual office environments under different lighting conditions
(2019-01) Kuş, Büşra
The aim of study iş to conduct a comparison between real and virtual environments from the spatial point of view under different lighting conditions. In this study, visually same office environments were created in real environment (RE) as well as in virtual environments (VE) in order to be able to observe only the perception between the two environments. The experiment was conducted in full-scale office environment and virtual environment by using Unity 3D program with participating of sixty people. These environments were appraised under 4000K (cool white light) and 6500K (daylight) lighting color temperatures. An office room in Bilkent University and Environmental Design building was used to carry out the experiments. The participants were asked to experience the environments firstly, later on they were as requested to answer the previously prepared questionnaire with semantic differential scale. As a result of this study one can say that the perceptions of both environments RE and VE were similar to some extend in more than half of the 12 adjective pairs under both color temperature. Adjectives such as usual-unusual, dynamic-static, spacious-confined and harmonious-discord demonstrated significant differences for both environments. Moreover, participants perceived real environment more spacious, usual, harmonious and less dynamic than virtual environment under both lighting conditions. Only the functional-nonfunctional and formal-informal adjective pairs behaved significantly different under 4000K and 6500K respectively. There were no significant effects of color temperatures in real and virtual environments.

The effects of achromatic and chromatic color schemes on participants' task performance in and appraisals of an office environment
(Wiley Periodicals, 2012-10) Öztürk, E.; Yilmazer, S.; Ural, S. E.
This study explores the effects of chroma on participants' performance and environmental appraisal of an office. The research was conducted in a full-scale experimental room designed as a private office where achromatic and chromatic color schemes with coequal values were applied. Sixty participants were assigned tasks and given a questionnaire to appraise the spatial color schemes. The findings show that chroma significantly affects performance and space appraisal. In terms of accuracy and time spent performance scores measured significantly better in the room with the chromatic scheme than those in the room with the achromatic scheme. The office with the chromatic scheme was found to be more pleasant, attractive, satisfying and dynamic than the one with the achromatic scheme, whereas the achromatic scheme was thought to be more formal and harmonious. Categorization of pleasantness, harmony, dynamism and spaciousness by factor analysis also showed differences between the achromatic and chromatic schemes.

The effects of color scheme on the appraisal of an office environment and task performance
(2010) Öztürk, Elif
The purpose of this study is to explore the differences between achromatic and chromatic schemes in the appraisal of an office environment and task performance. To investigate only the hue effect on the subjective impressions of the offices and participants’ performance, it was important to use the colors with the same value (lightness) on the surfaces of achromatic and chromatic scheme. The study has two phases. In the first phase, a field survey was conducted at the Fine Arts Faculty of Bilkent University to obtain data in order to determine the artificial lighting and color specifications of the experiment room that was to be used in the experimental study. In the second phase, an experimental study was conducted. The same sample group participated in the experiment for two color schemes which were achromatic and chromatic. The participants were sixty office workers who are academic and administrative staff from different departments of Bilkent University in Ankara. The study was carried out in an office room at the Department of Interior Architecture and Environmental Design at Bilkent University, and the room was redesigned according to the purposes of the study. In the first stage of the experiment participants were tested for color vision deficiencies and after a few minutes of adaptation, they were given performance tasks consisting of problem-solving and proofreading tests while the coordinator of the experiment was timing this process. Later, the participants evaluated the task they performed (self-report of the task) and the presented office setting by filling out the questionnaire, consisting of a set of bipolar adjective pairs, preference and association questions in 5 point scale likert-type and open-ended questions. In the second stage, the same procedure was followed for the other color scheme (achromatic or chromatic). Statistical Package for the Social Science (SPSS) 13.0 was used to analyze the data. It was found that the office environment with chromatic scheme was found more pleasant, attractive, satisfying and dynamic than the achromatic scheme. In terms of task performance the results showed that participants’ performances were better in the chromatic scheme than their performance in the achromatic scheme.
