ÖgeExploring the concept of product attachment: The case of precious objects(Graduate School, 2022-01-28) Gökaltay, Elif ; Çelikoğlu, Özge ; 502181903 ; Industrial Design ; Endüstriyel TasarımWhile most products lose their appeal with time some remain meaningful and precious for users that experience a form of attachment towards them. This thesis focuses on the concept of product attachment which is found to be a factor that leads users to keep their existing products for more prolonged periods instead of replacing them. This behavioral change results in lowering the high rate of consumption. The thesis consists of six chapters. The first chapter is an introduction covering the background information about the subject and presenting the aim and scope of the study along with the research questions. The second chapter includes a literature review covering topics of product attachment, meaningful products, and emotional durability. Product attachment is explored by examining product-user relationships. In the third chapter, the methodology is explained. The research has a qualitative and exploratory quality and has an interpretive approach. Two research methods have been implemented to gather data, these were cultural probes and semi-structured interviews. Literature concerning the implemented methods was provided. In the fourth chapter, all stages of fieldwork are covered. The primary research was conducted using the method of cultural probes. This method involves a period that provokes a reflection process and was selected to gather insightful material regarding participants' experiences. Following a one-week cultural probes process, a series of semi-structured interviews have been conducted to gain a deeper understanding of the data gathered from the primary research. The fifth chapter consists of the analysis and interpretation of the findings. The method of qualitative content analysis was implemented, and the according literature is presented. The cultural probes material was analyzed under sixteen main categories which corresponded to tasks that were taken as units during the coding process. The findings were interpreted and presented under main categories and subcategories. A data-driven and concept-driven strategy were pursued. As interviews were audio recorded all were transcribed. The sixth chapter is the last chapter that consists of the conclusion where it has been stated that the findings and categories derived from the research analysis corresponded with the categories of the product attachment literature.
ÖgeInvestigating user experiences with domestic service robots through metaphors: The case of robot vacuum cleaners(Graduate School, 2022-01-21) Önal, Onurcan ; Çelikoğlu, Özge ; 502181907 ; Industrial Design ; Endüstriyel TasarımUsing metaphors, telling something by meaning something other, is common in daily speech and they are thought to be constructing our conceptual structures. This thesis aims to elicit metaphors used in the expressions about domestic service robots, which are drawing the attention of users and intertwined with daily lives. Conceptualization of and interaction with domestic service robots through metaphors and metaphors' effects on the domestic service robot experience are the key issues of this research. These issues were studied through robot vacuum cleaners, a popular member of the domestic service robot genre, and with this aim, three research methods were applied within an empirical study. These research methods included unobtrusive methods, surveying and semi-structured interviews, each of which had specific sub-purposes within the study design. Firstly, unobtrusive methods were used as a discovery tool for the research field without disturbing the setting. The key insights for conducting further research methods, which comprised product specifications in the market, marketing arguments, initial steps of experiencing robot vacuum cleaners and common problems with these products, were found out with this method. Secondly, a survey research method was used to both determine the demographic profile of robot vacuum cleaner users and measure their perceptions of the robot vacuum cleaners they have been experiencing with semantic differential scales. It was observed in the survey results (N=118) that participants had been experiencing their robot vacuum cleaners for up to more than 3 years. At the same time, participants were seen as perceiving their robot vacuum cleaners as nonanthropomorphic, inanimate, likable and intelligent when asked directly with semantic differential scale items. These results provided a basis for the next research step in terms of giving tangible outcomes for user-profiles and their perceptions. Thirdly, semi-structured interviews were conducted with the voluntary survey participants. The interview schedule included topics covering participants' overall robot vacuum cleaner experience from the purchasing phase or daily routines to maintenance, difficulties, anecdotes or wishes. These interviews (N=10) were recorded and transcriptions of the interviews were analyzed by utilizing the qualitative content analysis (QCA) method. In QCA, the interview transcriptions were segmented into units of coding and each unit was matched with one or more code from the coding frame, which was structured upon concept-driven and data-driven approaches. It was seen in the QCA results that most of the units were about participants' robot vacuum cleaner experiences and half of all units included metaphors. Furthermore, experience and metaphor codes most frequently co-occurred together. This connection signaled a tight connection between the robot vacuum cleaner experience and metaphors. When this connection was elaborated in terms of metaphors, it was determined that there were four main metaphor source groups in the expressions of participants, which were "person", "animal", "space" and "vehicle". The interpretation of metaphor source groups was made afterward. Individual metaphor sources in the groups were are analyzed upon their saliences and relatednesses. The most frequent source in the most frequent source group "person" is seen as the "housekeeper" metaphor source. "Housekeeper" metaphor was salient with its "cleaning" and "autonomy" aspects, which are matching with the intended purpose of "robot" "vacuum cleaner"s. Additionally, "pet" metaphors were found salient with their "friendliness" and "playfulness" aspects or "house" metaphor sources were highlighted with their being "supply unit"s, which were indirectly contributing to "person" metaphors. Finally, a matrix that includes the metaphor sources and saliences/relatednesses is presented with the matches of determined metaphor sources and their saliences/relatednesses as a summary of the findings. These findings were then considered as direct answers to the research questions of the thesis. The study was then concluded by interpreting the use of given metaphors as the means of providing a fluent acceptance at domestic environments and an engaging experience to its users.
