Assessment of Spatial Factors Influencing User Satisfaction in Quick-Casual Restaurants
(2022) Saleh Ahmadi, Reda R.; Akbay, Saadet
Users' evaluations of the restaurant environment are influenced by various design factors and their level of satisfaction and comfort, of which colour is an essential component. Several studies in the literature have demonstrated the influence of colour in interior design on human behaviour and psychology in various contexts. This study investigates the spatial factors influencing users' satisfaction in quick-casual restaurants. User satisfaction was measured using four major elements: product, service, price, and physical environment. This study used a questionnaire to assess user satisfaction in four quick-casual restaurants in Ankara, Turkey. The emphasis on colour effects was intended to evaluate the physical environment of the restaurants. The study results, which included the participation of 120 restaurant users, show that participants rated the various restaurant environments in a variety of ways. The assessments provided by the participants are statistically tested for significant differences based on gender, frequency of restaurant usage, and colour properties for both user satisfaction and the evaluation of the physical environment using one-way between groups of variance (ANOVA) (p < 0.05). The findings show that demographics have a limited influence on restaurant user satisfaction, though it varies depending on colour properties. Additionally, the results suggest that the environmental colours of quick-casual restaurants significantly influence user satisfaction, overall satisfaction levels, and the evaluation of the physical environments
Colour harmony: The ideality of pleasurableness
(2017) Akbay, Saadet; Joao João Durão, Maria
The search for the essence of colour harmony has a long tradition that, being a quest for aesthetic values, remains a contemporary question insofar as it addresses the interrelated issues of both beauty and pleasure. Colour harmony has been discussed in terms of two different points of view. As a measurement of aesthetics, the researches of colour harmony are based on the discovery of its systematic rules by identifying the relationship between colours and its aesthetic value in beauty and harmony. The proportional and orderly arrangements of colours and their relations to mathematics are the main concerns of this first approach. As a measurement of emotion, colour harmony is regarded as subject matter of pleasure, subjective feeling which is peculiar to an individual. Relying on the second approach, many studies have been conducted to identify the reasons behind why colour combinations are perceived as beautiful, pleasant, and harmonious. Thus, this paper is a retrospective review of the literature of colour harmony, its theories, and principles considering the two approaches. The assumption is that, in either case, colour harmony is grounded in a search for the ideality of pleasurableness.
Effects of Colour on the Sense of Immersion in Virtual Interior Environments
(2021) Gökmenoğlu, Firdevs; Akbay, Saadet
This 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.
OLED Lighting and Human Circadian System: A Review
(2021) Avcı, Ayşe Nihan; Akbay, Saadet
Light 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.
Pandemi Sürecinde İç Mimarlık Lisans Eğitim Müfredatının Uzaktan Eğitim Modeline Adaptasyonu: Çankaya Üniversitesi Örneği
(2021) Urak, Gediz; Dökmeci Yörükoğlu, Papatya Nur; Akbay, Saadet
Çankaya 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.

Progression of Color Decision Making in Introductory Design Education
(Wiley, 2017) Ural, Sibel Ertez; Akbay, Saadet; Altay, Burcak
Color 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.

Understanding of User Evaluations on Fun Products
(Sciencepark Sci, Organization & Counseling Ltd, 2017) Akbay, Saadet
The fields of human-computer interaction and interaction design are increasingly dealing with the issues of fun, enjoyment and pleasure throughout the last two decades. The concept of fun becomes a concern in the development of usability of a product. Fun is an attribute considered to be an emotional aspect of interaction of a product. The evaluations and interpretations of fun on products are, therefore, subjective and personal which is peculiar to a user. A study, hence, was conducted to explore the term fun in everyday experience products. The aim is to understand what features and characteristics of a product make it fun and enjoyable to use. A total of twenty-nine users participated in the study. Each participant was interviewed individually in order for his/her personal attributes, interpretations and evaluations of fun to be elicited from a pool of thirty-two products. The participants' responses to open-ended questions were qualitatively analyzed by the use of content analysis procedure. The collected data was then grouped under four main categories which are visual aspect, functionality, usability, and contextual content. The findings of the study show that visual aspect of a product is the most concerned feature, followed by contextual content, usability and functionality, when evaluating the fun in everyday experience products.
