    Supporting designers in the sharing economy through a generative design cards toolkit
    (Association for Computing Machinery (ACM), 2022) Fedosov, A.; Ochsenbein, L.; Huang E.; Department of Media and Visual Arts; Subaşı, Özge; Faculty Member; Department of Media and Visual Arts; College of Social Sciences and Humanities; 240920
    Non-profit approaches in the sharing economy are proliferating in everyday life (e.g., tool libraries, food sharing collectives). They focus on promoting social, economic, and ecological sustainability within local communities. However, prior research uncovered emergent challenges of these communities that prevent their endurance and growth. Despite growing academic interest in studying these communities, designers found it difficult to effectively adopt newly generated knowledge in practice. Addressing the research-practice gap, we developed a translational resource for design practitioners to conceptualize new value-added features for supporting technologies in the sharing economy context. Specifically, we synthesized emergent challenges in non-profit sharing economy communities and key social and environmental sustainability efforts in design research into a familiar format for designers - the card-based toolkit to support generative design activities. Beyond introducing the toolkit, we offer a ""how-to""guide for its adoption in collaborative settings.

    Kart-ON: affordable early programming education with shared smartphones and easy-to-find materials
    (Association for Computing Machinery (ACM), 2020) Department of Computer Engineering; Sezgin, Tevfik Metin; Sabuncuoğlu, Alpay; Faculty Member; Department of Computer Engineering; College of Engineering; Graduate School of Sciences and Engineering; 18632; N/A
    Programming education has become an integral part of the primary school curriculum. However, most programming practices rely heavily on computers and electronics which causes inequalities across contexts with different socioeconomic levels. This demo introduces a new and convenient way of using tangibles for coding in classrooms. Our programming environment, Kart-ON, is designed as an affordable means to increase collaboration among students and decrease dependency on screen-based interfaces. Kart-ON is a tangible programming language that uses everyday objects such as paper, pen, fabrics as programming objects and employs a mobile phone as the compiler. Our preliminary studies with children (n=16, mage=12) show that Kart-ON boosts active and collaborative student participation in the tangible programming task, which is especially valuable in crowded classrooms with limited access to computational devices.

    Take back control of your time: design activity for reflecting on time and timekeeping practices
    (The Design Society, 2021) Umulu, Sıla; Şener, Bahar; Department of Media and Visual Arts; Yıldız, Mert; Coşkun, Aykut; Faculty Member; Department of Media and Visual Arts; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 165306
    This paper reports on the procedure and the results of a design activity carried out to reflect on time and timekeeping practices. The design activity involved a diary study followed by an idea generation workshop in the scope of a graduate level course with the participation of 12 graduate level industrial design students. The paper first explains the procedure of the design activity. Then, it presents the outcomes under two themes: i) timekeeping related insights: the students’ reflections on their timekeeping practices and ideas on how to improve these practices to support wellbeing; ii) pedagogical insights: students' thoughts and instructors’ reflections on the online diary-keeping and conducting the workshop remotely. The findings are believed to be beneficial for inspiring designers interested in designing interventions to support better time management practices; and for design educators interested in conducting remote diary study and/or workshop in distance education settings.

    Decoupling of real and digital content in projection-based augmented reality systems using time multiplexed image capture
    (Society for Imaging Science and Technology (IS_T), 2017) Department of Electrical and Electronics Engineering; Soomro, Shoaib Rehman; Ulusoy, Erdem; Ürey, Hakan; Faculty Member; Department of Electrical and Electronics Engineering; College of Engineering; N/A; 111927; 8579
    Projection-based augmented reality systems overlay digital information directly on real objects, while at the same time use cameras to capture the scene information. A common problem with such systems is that cameras see the projected image besides the real objects to some degree. This crosstalk reduces the object detection and digital content registration abilities. The authors propose a novel time sharing-based technique that facilitates the real and digital content decoupling in real time without crosstalk. The proposed technique is based on time sequential operation between a MEMS scanner-based mobile projector and rolling shutter image sensor. A MEMS mirror-based projector scans light beam in raster pattern pixel by pixel and completes full frame projection over a refresh period, while a rolling shutter image sensor sequentially collects scene light row by row. In the proposed technique, the image sensor is synchronized with scanning MEMS mirror and precisely follows the display scanner with a half-period lag to make the displayed content completely invisible for camera. An experimental setup consisting of laser pico projector, an image sensor, and a delay and amplifier circuit is developed. The performance of proposed technique is evaluated by measuring the crosstalk in captured content and sensor exposure limit. The results show 0% crosstalk in captured content up to 8 ms sensor exposure. High capture frame rate (up to 45 fps) is achieved by cyclically triggering a 3.2 MP, 60 fps CMOS sensor and using a 60 Hz pico projector. © 2017 Society for Imaging Science and Technology.

    Social drone companion for the home environment: a user-centric exploration
    (Association for Computing Machinery (ACM), 2017) Karjalainen, Kari Daniel; Romell, Anna Elisabeth Sofia; Ratsamee, Photchara; Fjeld, Morten; Obaid, Mohammad; Yantaç, Asım Evren; Faculty Member; KU Arçelik Research Center for Creative Industries (KUAR) / KU Arçelik Yaratıcı Endüstriler Uygulama ve Araştırma Merkezi (KUAR); 52621
    Recent research has focused on how to facilitate interaction between humans and robots, giving rise to the field of human robot interaction. A related research area is human-drone interaction (HDI), investigating how interaction between humans and drones can be expanded in novel and meaningful ways. In this work, we explore the use of drones as companions in a home environment. We present three consecutive studies addressing user requirements and design space of companion drones. Following a user-centered approach, the three stages include online questionnaire, design workshops, and simulated virtual reality (VR) home environment. Our results show that participants preferred the idea of a drone companion at home, particularly for tasks such as fetching items and cleaning. The participants were also positive towards a drone companion that featured anthropomorphic features.
