Publication Open Access Tactowel: a subtle sports performance display for giving real-time performance feedback in tennis(Multidisciplinary Digital Publishing Institute (MDPI), 2021) Department of Media and Visual Arts; Havlucu, Hayati; Özcan, Oğuzhan; Coşkun, Aykut; Faculty Member; 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); College of Social Sciences and Humanities; N/A; 12532; 165306Sports technology enhances athletes' performance by providing feedback. However, interaction techniques of current devices may overwhelm athletes with excessive information or distract them from their performance. Despite previous research, design knowledge on how to interact with these devices to prevent such occasions are scarce. To address this gap, we introduce subtle displays as real-time sports performance feedback output devices that unobtrusively present low-resolution information. In this paper, we conceptualize and apply subtle displays to tennis by designing Tactowel, a texture changing sports towel. We evaluate Tactowel through a remote user study with 8 professional tennis players, in which they experience, compare and discuss Tactowel. Our results suggest subtle displays could prevent overwhelming and distracting athletes through three distinct design strategies: (1) Restricting the use excluding duration of performance, (2) using the available routines and interactions, and (3) giving an overall abstraction through tangible interaction. We discuss these results to present design implications and future considerations for designing subtle displays.Publication Open Access Interest rate demands and television viewing-is a single exposure more influential than routine viewing?(Sage, 2017) Reizer, Abira; Ben Zion, Uri; Department of Media and Visual Arts; Hetsroni, Amir; Faculty Member; Department of Media and Visual Arts; College of Social Sciences and HumanitiesThis study examined the impact of media consumption, and particularly exposure to television, on decisions regarding interest rate demands. One hundred and fifty-four participants were randomly divided into two groups: in the manipulation group, participants were exposed to a news clip about an Iranian nuclear attack on Israel, whereas in the control group, the participants were not exposed to the film. Both groups filled a questionnaires regarding their interest rate requirements in different situations, their media conception behaviors, and demographic questionnaires. Frequent routine viewing increased the interest rate demands only among participants in the manipulation group, but the manipulation itself did not have a significant effect on interest rate demands. The results are explained in terms of cultivation theory.Publication Open Access 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; 240920Non-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.Publication Open Access Toward detecting the zone of elite tennis players through wearable technology(Frontiers, 2022) Havlucu, Hayati; N/A; Department of Psychology; Department of Media and Visual Arts; Akgün, Barış; Eskenazi, Terry; Coşkun, Aykut; Özcan, Oğuzhan; Faculty Member; Faculty Member; Faculty Member; Department of Psychology; 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 Engineering; College of Social Sciences and Humanities; 258784; 258780; 165306; 12532Wearable devices fall short in providing information other than physiological metrics despite athletes' demand for psychological feedback. To address this, we introduce a preliminary exploration to track psychological states of athletes based on commercial wearable devices, coach observations and machine learning. Our system collects Inertial Measuring Unit data from tennis players, while their coaches provide labels on their psychological states. A recurrent neural network is then trained to predict coach labels from sensor data. We test our approach by predicting being in the zone, a psychological state of optimal performance. We conduct two experimental games with two elite coaches and four professional players for evaluation. Our learned models achieve above 85% test accuracy, implying that our approach could be utilized to predict the zone at relatively low cost. Based on these findings, we discuss design implications and feasibility of this approach by contextualizing it in a real-life scenario.Publication Open Access Systems approach to health service design, delivery and improvement: a systematic review and meta-analysis(BMJ Publishing Group, 2021) Komashie, Alexander; Ward, James; Bashford, Tom; Dickerson, Terry; Kaya, Gülsüm Kübra; Liu, Yuanyuan; Kuhn, Isla; Kohler, Katharina; Boddy, Nicholas; O'Kelly, Eugenia; Masters, Joseph; Dean, John; Meads, Catherine; Clarkson, P. John; Department of Media and Visual Arts; Günay, Aslı; Faculty Member; Department of Media and Visual Arts; College of Social Sciences and HumanitiesObjectives: to systematically review the evidence base for a systems approach to healthcare design, delivery or improvement. Design: systematic review with meta-analyses. Methods: included were studies in any patients, in any healthcare setting where a systems approach was compared with usual care which reported quantitative results for any outcomes for both groups. We searched Medline, Embase, HMIC, Health Business Elite, Web of Science, Scopus, PsycINFO and CINAHL from inception to 28 May 2019 for relevant studies. These were screened, and data extracted independently and in duplicate. Study outcomes were stratified by study design and whether they reported patient and/or service outcomes. Meta-analysis was conducted with Revman software V.5.3 using ORs-heterogeneity was assessed using I-2 statistics. Results: of 11 405 records 35 studies were included, of which 28 (80%) were before-and-after design only, five were both before-and-after and concurrent design, and two were randomised controlled trials (RCTs). There was heterogeneity of interventions and wide variation in reported outcome types. Almost all results showed health improvement where systems approaches were used. Study quality varied widely. Exploratory meta-analysis of these suggested favourable effects on both patient outcomes (n=14, OR=0.52 (95% CI 0.38 to 0.71) I-2=91%), and service outcomes (n=18, OR=0.40 (95% CI 0.31 to 0.52) I-2=97%). Conclusions: this study suggests that a systems approaches to healthcare design and delivery results in a statistically significant improvement to both patient and service outcomes. However, better quality studies, particularly RCTs are needed.Publication Open Access Envisioning social drones in education(Frontiers, 2022) Johal, W.; Obaid, M.; Department of Media and Visual Arts; N/A; Yantaç, Asım Evren; Gatos, Doğa Çorlu; Faculty Member; Department of Media and Visual Arts; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 52621; N/AEducation is one of the major application fields in social Human-Robot Interaction. Several forms of social robots have been explored to engage and assist students in the classroom environment, from full-bodied humanoid robots to tabletop robot companions, but flying robots have been left unexplored in this context. In this paper, we present seven online remote workshops conducted with 20 participants to investigate the application area of Education in the Human-Drone Interaction domain; particularly focusing on what roles a social drone could fulfill in a classroom, how it would interact with students, teachers and its environment, what it could look like, and what would specifically differ from other types of social robots used in education. In the workshops we used online collaboration tools, supported by a sketch artist, to help envision a social drone in a classroom. The results revealed several design implications for the roles and capabilities of a social drone, in addition to promising research directions for the development and design in the novel area of drones in education.
