Conference Object Parametric Design Studio in Interior Architecture Education: A Case of Integration of Colour Design(2021) Mutlu Tunca, Gülru; Akbay, Saadet; Demirbaş, UfukThis paper aims to disclose the alternative ways in which the interior architecture students integrate their colour design decisions as one of the main determinants of the project from the beginning of the design process. This revised approach is proposed in the third-year interior design studio course mainly specialises in the parametric design approaches in interior spaces. This paper outlines how colour design is integrated into stages thoroughly in the parametric interior design studio. The main motivation is to maintain a procedure that will make colour design decisions evolve through the whole design process as an integral part of it. This study suggests that producing colour charts from the initial stages of the design process, making colour design decisions for interior environments in 3D visualisations at all stages are critical for improving the student projects and helps them to envision and effectively reflect their atmosphere creations.Conference Object Pandemi Sürecinde İç Mimarlık Lisans Eğitim Müfredatının Uzaktan Eğitim Modeline Adaptasyonu: Çankaya Üniversitesi Örneği(2021) Urak, Gediz; Dökmeci Yörükoğlu, Papatya Nur; Akbay, SaadetÇankaya Üniversitesi İç Mimarlık Bölümü, Covid-19 pandemisinin ortaya çıkması ile 30 Mart 2020 tarihi itibariyle eğitime uzaktan eğitim yöntemiyle devam etmek durumunda kalmıştır. Bu süreçte, Bölüm müfredatında yer alan derslerin uzaktan eğitim modeline dönüştürülmesi için yoğun bir çaba harcanmış ve detaylı bir hazırlık süreci yaşanmıştır. Müfredatın değiştirilmeden adapte edilmesi gerekliliği nedeniyle, bu çalışma kapsamında uzaktan eğitime adaptasyon sürecinin kilit aşamaları, eğitimin kalitesi ve sürdürülebilirliği tartışılmış, pandeminin, iç mimarlık eğitim sürecine olan kısa vadeli etkileri ve lisans eğitim müfredatında yapılan adaptasyonları sunulmuştur. Buna ek olarak, pandemi süreci nedeniyle ‘acil uzaktan eğitim’ ve ‘uzaktan eğitim’ şeklinde verilecek olan derslere hazırlık, derslerin işleniş biçimi, sınav uygulamaları, öğrenci başarı durumları ve görüşleri de aktarılmıştır. Öğrencilere uygulanan ön anket sonuçları, öğrencilerin ‘acil uzaktan eğitim’ sürecine katılımlarının elektronik cihaz, program ve internet erişimi konuları kapsamında mümkün olduğunu ve süreci köklü olarak etkileyecek aksaklıkların yaşanmayacağını ortaya koymuştur. Bunun dışında, öğretim elemanlarından alınan ‘uzaktan eğitim’ ile ilgili geri bildirimlerin sonuçları, teorik derslerdeki uzaktan eğitim sürecine adaptasyonun uygulamalı derslere göre belirgin olarak daha kısa sürede ve kolay olduğunu göstermiştir.Conference Object OLED Lighting and Human Circadian System: A Review(2021) Avcı, Ayşe Nihan; Akbay, SaadetLight is a form of energy that affects the human sleep cycle, working hours, alertness, productivity, and well-being. As one of the most essential environmental factors, lighting requires extensive research to understand the human-environment interaction. Earlier studies reveal that various artificial lighting technologies are utilised to investigate the human circadian system; experiments employing solid state lighting (SSL) sources are still being conducted to determine how the human circadian system is affected. Due to the advantages of OLED lighting, there is a need to enhance the use of this form of artificial lighting in an indoor environment. This paper focuses on a literature review on artificial lighting sources, particularly OLED lighting, which has been used from the past to the present. This paper also discusses how OLED lighting can be utilised to alter the human circadian system in an indoor environment.Conference Object Effects of Colour on the Sense of Immersion in Virtual Interior Environments(2021) Gökmenoğlu, Firdevs; Akbay, SaadetThis paper investigates the effects of colour on the sense of immersion in virtual interior environments. Since colour in interior environments is vital for the perception of place, the three dimensions of colour, namely hue,saturation, and lightness (HSL), were evaluated as elementsfor transferring colour to virtual environments (VEs). In this context, this study aims to investigate how the sense of immersion in virtual interior environments differs depending on hue, saturation, and lightness and examines the extent to which colour dimensions influence the sense of immersion in VEs. For this, the HSL colour space was utilised to establish varying degrees of colours. An online survey was conducted to understand the people’s sense of immersion in different virtual interior settings. The study’s results suggest that perception of colour influences the sense of immersion in virtual environments.Article Citation - WoS: 2Citation - Scopus: 2Progression of Color Decision Making in Introductory Design Education(Wiley, 2017) Ural, Sibel Ertez; Akbay, Saadet; Altay, BurcakColor comprises both subjective and objective aspects within its contextual nature. Research on color design tends to explore this seemingly contradictory concerns from theoretical point of view, as well as architectural and design practice. The aim of this study was to observe subjective, intuitive or heuristic and objective, knowledge-based or analytical attitudes toward color in design education. In the study 84 introductory design students were surveyed progressively to understand their color decision criteria after completion of three 2-dimensional colored exercises, specific in terms of color education. Students' responses to open-ended questions were coded according to the 5 categories, under 2 decision making processes derived from the literature; heuristic approach: preferential and symbolic criteria, and analytic reasoning: formal, thematic, and systematic criteria. A distinction between associative and emotional aspects of symbolic criteria was also revealed by the data analysis. The findings showed a shift from heuristic responses to analytic reasoning, as expected. Additionally, it is also investigated that students not only used heuristic approaches but also analytical components (formal and systematic) of color decision making in varying degrees as well, even before any color subjects covered. Thematic color decisions became a major part of the students' design considerations upon completion of color subjects. The observed increase in the number of color criteria interrelated by the students' among almost all categories explicated a complex decision making process particularly in color design and education. These findings were expected to lead to some further understanding in color decision making in design.Article Citation - WoS: 3Citation - Scopus: 3Construing Colours Using Repertory Grid Technique: an Idiographic Approach in Colour Perception(Wiley, 2022) Akbay, Saadet; Borekci, Naz A. G. Z.This article offers an alternative methodological approach to the exploration of subjective experiences by studying individuals' personal views of perceived colours. The study aims to investigate the construals of individuals related to perceived colours using an idiographic approach. The subjective approach proposed is based on the theory of personal construct psychology and the methodology of the repertory grid technique. A repertory grid experiment was conducted to determine individuals' ways of construing colours and examine the collective understanding of the content and structure of individuals' construals concerning perceived colours. Sixty undergraduate students participated in the experiment, yielding 60 different repertory grids that included a number of personal constructs indicating the construal process of participants in differentiating between 11 basic colours. Participants produced their own semantic bipolar dimensions for comparing the perceived colours and creating differential ratings according to their personal constructs. The elicited data were evaluated using qualitative content analysis to understand the differences between individual systems of constructs and investigate the commonality of shared constructs relating to colours. The data were also analyzed quantitatively to investigate the common structure of and interrelationship between elicited constructs and perceived colours. The outcomes have the potential to contribute to academic and practical knowledge concerning colour perception, as well as encouraging further studies with an idiographic approach.Article Citation - WoS: 5Citation - Scopus: 6Audio-Visual Interactions and the Influence of Colour on Noise Annoyance Evaluations(Springer Singapore Pte Ltd, 2021) Kitapci, Kivanc; Akbay, SaadetThis study aims to examine the influence of colour exposure on noise annoyance. Previous studies in the literature have focused mostly on the effects of colour exposure on loudness judgements; however, due to the cognitive nature of multisensory perception, the influence of colour on noise annoyance also needs to be investigated. Our experiments were designed to administer non-information-carrying sound signals (i.e. white noise) and visual stimuli (i.e. abstract colour samples) and to limit visual and auditory contextual information. Participants were asked to evaluate noise annoyance on an 11-point International Commission on Biological Effects of Noise (ICBEN) scale. The experiments were conducted in the form of audio-visual tests. During these tests, random combinations of three white noise sound samples with sound pressure levels of 66 dB(A) (-4 dB[A] acoustic condition), 70 dB(A) (0 dB[A] acoustic condition) and 74 dB(A) (+4 dB[A] acoustic condition), and six visual stimuli, including the elementary colours of the Natural Colour System (NCS)-yellow (Y), red (R), blue (B), green (G), white (W) and black (S)-were presented to a total of 42 participants. The black colour sample was used to measure the audio-only control condition for the three white noise sound samples. The results of the study reveal that the effects of sound, the effects of colour and the interaction effects of colour and sound on perceived noise annoyance were statistically significant. The effects of colour on the loudness evaluations of the previous studies and the effects of colour on noise annoyance evaluations presented in this study show very similar and concordant results, indicating that the effects of colour on noise annoyance depend on the sound pressure level (SPL). The results indicate that the hue contrasts of red-green, red-blue and yellow-blue and the lightness contrast of yellow-blue influenced perceived noise annoyance when the SPL was low or high. Within the contrast pairs, red and yellow were perceived to be annoying, whereas blue and green were perceived to be non-annoying.Article Color Perception in Correlated Color Temperature of Led Lighting(2018) Akbay, Saadet; Avcı, Ayşe NihanColor and light are inseparable entities that are the essential design factors in the field of interior architecture. When the light changes, the perceived color appearance of a surface within an interior environment also changes. The change in color perception is not only related to the type of a light source or the intensity of illumination, but also to the correlated color temperature (CCT) of a light source. The aim of this study is to understand how different CCTs of light-emitting diode (LED) lighting influence the color perception. A study is conducted to compare the perceptive color tendencies for inherent colors under two different CCTs of LED lighting, i.e. warm (2700º K) and cool (4000º K). In the study, Natural Color System (NCS) is utilized as a color notation system to reveal the possible tendencies and patterns concerning the relationship between the inherent and perceived colors. The general tendencies for the perceived colors revealed similar patterns in the nuance (i.e. blackness and chromaticness) color area for each inherent color and showed dispersion on the hue color area under the CCTs of both 2700º K and 4000º K LED lighting.Article Progression of color decision making in introductory design education(Wiley, 2017) Ural, Sibel Ertez; Akbay, Saadet; Altay, BurçakColor comprises both subjective and objective aspects within its contextual nature.
