    Learning from the users for spatio-temporal data visualization explorations on social events
    (Springer Int Publishing Ag, 2016) N/A; Department of Media and Visual Arts; Çay, Damla; Yantaç, Asım Evren; PhD Student; Faculty Member; Department of Media and Visual Arts; KU Arçelik Research Center for Creative Industries (KUAR) / KU Arçelik Yaratıcı Endüstriler Uygulama ve Araştırma Merkezi (KUAR); Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 52621
    The amount of volunteered geographic information is on the rise through geo-tagged data on social media. While this growth opens new paths for designers and developers to form new geographical visualizations and interactive geographic tools, it also engenders new design and visualization problems. We now can turn any kind of data into daily useful information to be used during our daily lives. This paper is about exploration of novel visualization methods for spatio-temporal data related to what is happening in the city, planned or unplanned. We, hereby evaluate design students' works on visualizing social events in the city and share the results as design implications. Yet we contribute by presenting intuitive visualization ideas for social events, for the use of interactive media designers and developers who are developing map based interactive tools.

    Make it a circular city: experiences and challenges from European cities striving for sustainability through promoting circular making
    (Elsevier, 2022) Metta, Julie; Bakırlıoğlu, Yekta; Bachus, Kris; Department of Media and Visual Arts; N/A; Coşkun, Aykut; Çay, Damla; Faculty Member; PhD Student; Department of Media and Visual Arts; KU Arçelik Research Center for Creative Industries (KUAR) / KU Arçelik Yaratıcı Endüstriler Uygulama ve Araştırma Merkezi (KUAR); College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 165306; N/A
    A growing number of cities are deploying circular economy practices to contribute to the Sustainable Development Goals (SDGs). Makerspaces are community-driven initiatives enabling the collaboration between a city's diverse stakeholders in that objective. They can enhance the citizens' contribution to circularity by engaging them in circular ''making'' activities (e.g., reuse, repair, sharing) and by providing them with novel means, skills, and knowledge in these activities. However, cities face various challenges during the process of engaging citizens to create a vibrant circular city. Based on an in-depth analysis of experiences and challenges in seven European cities, which attempted to embrace the SDGs through circular making activities, this paper presents ten engagement-related challenges and five strategies to overcome them. Integrating these challenges and strategies in a strategy-challenge matrix offers several recommendations for cities striving to address SDGs through establishing and maintaining circular makerspaces.

    What is happening in the city? A case study for user-centred geovisualisation design
    (Taylor & Francis Ltd, 2019) Nagel, Till; N/A; Department of Media and Visual Arts; Çay, Damla; Yantaç, Asım Evren; PhD Student; Faculty Member; Department of Media and Visual Arts; KU Arçelik Research Center for Creative Industries (KUAR) / KU Arçelik Yaratıcı Endüstriler Uygulama ve Araştırma Merkezi (KUAR); Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 52621
    For citizens, being aware of what is happening in their urban surroundings becomes challenging as more information from diverse sources becomes available. In this paper, we describe our user-centered approach of designing an interactive tool making use of urban data visualisations to facilitate people's decisions about social and cultural events. After gathering the needs of urban actors through formative user studies, we identified beneficial data types and collected a variety of data sets from publicly accessible online sources. For the aim of enabling casual exploration of events in the city, we designed a set of geovisualisation prototypes and designed a variety of evaluative user studies based on established geovisualisation techniques. The main aim here is to enable casual exploration of events in the city more than the intended search for specific events. We developed two prototypes that make use of two different geo-visualisations to represent events: Prototype A uses common location markers, and prototype B uses a novel glyph design to visualize more types of data at a glance. We share the lessons learned from the results of our study, which will inform the design of geographical data visualisations for citizens.

    The design of social drones a review of studies on autonomous flyers in inhabited environments
    (Assoc Computing Machinery, 2019) Baytaş, Mehmet Aydın; Zhang, Yuchong; Obaid, Mohammad; Fjeld, Morten; N/A; Department of Media and Visual Arts; Çay, Damla; Yantaç, Asım Evren; PhD Student; Faculty Member; Department of Media and Visual Arts; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 52621
    The design space of social drones, where autonomous flyers operate in close proximity to human users or bystanders, is distinct from use cases involving a remote human operator and/or an uninhabited environment; and warrants foregrounding human-centered design concerns. Recently, research on social drones has followed a trend of rapid growth. This paper consolidates the current state of the art in human-centered design knowledge about social drones through a review of relevant studies, scaffolded by a descriptive framework of design knowledge creation. Our analysis identified three high-level themes that sketch out knowledge clusters in the literature, and twelve design concerns which unpack how various dimensions of drone aesthetics and behavior relate to pertinent human responses. These results have the potential to inform and expedite future research and practice, by supporting readers in defining and situating their future contributions. The materials and results of our analysis are also published in an open online repository that intends to serve as a living hub for a community of researchers and designers working with social drones.

    PDC places Turkey will run with a focus on local issues of participation, aiming to build and strengthen the Participatory Design ecosystem in Turkey. In line with the PDC 2022 central theme of embracing cosmologies in Participatory Design (PD), this aim will be realized by two kinds of activities. First, Skills Workshops are sessions where the general public and marginalized communities (e.g., migrants, women) will be introduced to PD through making together. Second, we will host a full day of project presentations and a panel discussion about PD, discussing current PD projects within Turkey and future directions and visions. The ultimate goal of these activities is to understand how PD is practiced in Turkey and identify the challenges we face around participation while building a community around it. This publication presents the activities conducted in the frame of PDC places in Turkey between August and September 2022.

    ColVis: collaborative visualization design workshops for diverse user groups
    (Ieee, 2020) Nagel, Till; N/A; Department of Media and Visual Arts; Çay, Damla; Yantaç, Asım Evren; PhD Student; Faculty Member; Department of Media and Visual Arts; KU Arçelik Research Center for Creative Industries (KUAR) / KU Arçelik Yaratıcı Endüstriler Uygulama ve Araştırma Merkezi (KUAR); Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 52621
    Understanding different types of users' needs can even be more critical in today's data visualization field, as exploratory visualizations for novice users are becoming more widespread with an increasing amount of data sources. The complexity of data-driven projects requires input from including interdisciplinary expert and novice users. Our workshop framework helps taking design decisions collaboratively with experts and novice users, on different levels such as outlining users and goals, identifying tasks, structuring data, and creating data visualization ideas. We conducted workshops for two different data visualization projects. For each project, we conducted a workshop with project stakeholders who are domain experts, then a second workshop with novice users. We collected feedback from participants and used critical reflection on the process. Later on, we created recommendations on how this workshop structure can be used by others. Our main contributions are, (1) the workshop framework for designing data visualizations, (2) describing the outcomes and lessons learned from multiple workshops.

    Insights from user studies for the graphical user interface design of a surgical operation robot
    (IADIS, 2014) Akgun, Gokhan b; Barkana, Duygun Erol; Department of Media and Visual Arts; N/A; Yantaç, Asım Evren; Çay, Damla; Faculty Member; PhD Student; Department of Media and Visual Arts; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 52621; N/A
    In this paper, we share insights from our user research studies for the development of the graphical user interface (GUI) design of a surgical operation robot. We had previously been developing the surgical interface (SI) for kidney tumor cryoablation by collecting eye-tracking data for fixation durations and number of fixations at informative regions from the users (Erol Barkana & Acik, 2014). Based on the analyzed data, we then explored the GUI for layout, color use and warning message communication by i) literature review, ii) evaluation using Nielsen's heuristics (Nielsen, 1994), and iii) re-design studies with design workshops. Relying on all the user feedback, we re-designed the GUI and conducted GUI design feedback survey. Here, we share our insights throughout this user research and GUI re-design process.

    Viewfinder: supporting the installation and reconfiguration of multi-camera motion capture systems with a mobile application
    (Assoc Computing Machinery, 2017) Batis, Emmanuel; Bylund, Mathias; Fjeld, Morten; N/A; N/A; Department of Media and Visual Arts; Baytaş, Mehmet Aydın; Çay, Damla; Yantaç, Asım Evren; PhD Student; PhD Student; Faculty Member; Department of Media and Visual Arts; Graduate School of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; N/A; 52621
    We present ViewFinder, a cross-platform mobile application to support the installation and reconfiguration of marker-based motion capture systems with multiple cameras. ViewFinder addresses a common issue when installing or reconfiguring motion capture systems: that system components such as cameras and the host computer can be physically separate and/or difficult to reach, requiring personnel to maneuver between them frequently and laboriously. ViewFinder allows setup technicians or end users to visualize the output of each camera in the system in a variety of ways in real time, on a smartphone or tablet, while also providing a means to make adjustments to system parameters such as exposure or marker thresholds on the fly. The app has been designed and evaluated through a process observing user-centered design principles, and effectively reduces the amount of work involved in installing and reconfiguring motion capture systems.

    Understanding user experience of COVID-19 maps through remote elicitation interviews
    (Institute of Electrical and Electronics Engineers (IEEE), 2020) N/A; Department of Media and Visual Arts; Çay, Damla; Yantaç, Asım Evren; Faculty Member; Department of Media and Visual Arts; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 52621
    During the coronavirus pandemic, visualizations gained a new level of popularity and meaning for a wider audience. People were bombarded with a wide set of public health visualizations ranging from simple graphs to complex interactive dashboards. In a pandemic setting, where large amounts of the world population are socially distancing themselves, it becomes an urgent need to refine existing user experience evaluation methods for remote settings to understand how people make sense out of COVID-19 related visualizations. When evaluating visualizations aimed towards the general public with vastly different socio-demographic backgrounds and varying levels of technical savviness and data literacy, it is important to understand user feedback beyond aspects such as speed, task accuracy, or usability problems. As a part of this wider evaluation perspective, micro-phenomenology has been used to evaluate static and narrative visualizations to reveal the lived experience in a detailed way. Building upon these studies, we conducted a user study to understand how to employ Elicitation (aka Micro-phenomenological) interviews in remote settings. In a case study, we investigated what experiences the participants had with map-based interactive visualizations. Our findings reveal positive and negative aspects of conducting Elicitation interviews remotely. Our results can inform the process of planning and executing remote Elicitation interviews to evaluate interactive visualizations. In addition, we share recommendations regarding visualization techniques and interaction design about public health data.
