Publication Metadata only Co-exploring the design space of emotional AR visualizations(Springer international Publishing ag, 2021) N/A; Department of Media and Visual Arts; Şemsioğlu, Sinem; 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); Koç Üniversitesi KARMA Gerçeklik Teknolojileri Eğitim, Uygulama ve Yayma Merkezi (KARMA) / Koç University KARMA Mixed Reality Technologies Training, Implementation and Dissemination Centre (KARMA); N/A; College of Social Sciences and Humanities; N/A; 52621Designing for emotional expression has become a popular topic of study in HCI due to advances in affective computing technologies. With increasing use of video-conferencing and video use in social media for different needs such as leisure, work, social communication, video filters, AR effects and holograms are also getting popular. in this paper, we suggest a framework for emotion visualization for natural user interface technologies such as augmented or Mixed Reality. the framework has been developed based on our analysis of visualizations formed during a series of emotion visualization workshops.Publication Metadata only Developing a prototyping method for involving children in the design of classroom robots(2018) Obaid, Mohammad; Barendregt, Wolmet; N/A; Department of Media and Visual Arts; Baykal, Gökçe Elif; Yantaç, Asım Evren; Researcher; 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; 52621Including children in the design of technologies that will have an impact on their daily lives is one of the pillars of user-centered design. Educational robots are an example of such a technology where children’s involvement is important. However, the form in which this involvement should take place is still unclear. Children do not have a lot of experience with educational robots yet, while they do have some ideas of what robot could be like from popular media, such as BayMax from the Big Hero 6 movie. In this paper we describe two pilot studies to inform the development of an elicitation method focusing on form factors; a first study in which we have asked children between 8 and 15 years old to design their own classroom robot using a toolkit, the Robo2Box, and a second study where we have compared the use of the Robo2Box toolkit and clay as elicitation methods. We present the results of the two studies, and discuss the implications of the outcomes to inform further development of the Robo2Box for prototyping classroom robots by childrenPublication Open Access Development of a cognitive robotic system for simple surgical tasks(InTech, 2015) Muradore, Riccardo; Fiorini, Paolo; Fiorini, Paolo; Barkana, Duygun Erol; Bonfe, Marcello; Borierol, Fabrizio; Caprara, Andrea; De Rossi, Giacomo; Dodi, Riccardo; Elle, Ole Jakob; Ferraguti, Federica; Gasperottil, Lorenza; Gassert, Roger; Mathiassen, Kim; Handini, Dilla; Lambercy, Olivier; Lil, Lin; Kruusmaal, Maarja; Manurung, Auralius Oberman; Meruzzi, Giovanni; Ho Quoc Phuong Nguyen; Freda, Nicola; Riolfo, Gianluca; Ristolainen, Asko; Sanna, Alberto; Secchi, Cristian; Torsello, Marco; Department of Media and Visual Arts; Yantaç, Asım Evren; Faculty Member; Department of Media and Visual Arts; College of Social Sciences and Humanities; 52621The introduction of robotic surgery within the operating rooms has significantly improved the quality of many surgical procedures. Recently, the research on medical robotic systems focused on increasing the level of autonomy in order to give them the possibility to carry out simple surgical actions autonomously. This paper reports on the development of technologies for introducing automation within the surgical workflow. The results have been obtained during the ongoing FP7 European funded project Intelligent Surgical Robotics (I-SUR). The main goal of the project is to demonstrate that autonomous robotic surgical systems can carry out simple surgical tasks effectively and without major intervention by surgeons. To fulfil this goal, we have developed innovative solutions (both in terms of technologies and algorithms) for the following aspects: fabrication of soft organ models starting from CT images, surgical planning and execution of movement of robot arms in contact with a deformable environment, designing a surgical interface minimizing the cognitive load of the surgeon supervising the actions, intra-operative sensing and reasoning to detect normal transitions and unexpected events. All these technologies have been integrated using a component-based software architecture to control a novelrobot designed to perform the surgical actions under study. In this work we provide an overview of our system and report on preliminary results of the automatic execution of needle insertion for the cryoablation of kidney tumours.Publication Metadata only Droeye: introducing a social eye prototype for drones(Association for Computing Machinery (ACM), 2020) Obaid, Mohammad; Mubin, Omar; Brown, Scott Andrew; Otsuki, Mai; Kuzuoka, Hideaki; Department of Media and Visual Arts; Yantaç, Asım Evren; Faculty Member; Department of Media and Visual Arts; College of Social Sciences and Humanities; 52621A drone agent can benefit from exhibiting social cues, as introducing behavioral cues in robotic agents can enhance interaction trust and comfort with users. In this work, we introduce the development and setup of a responsive eye prototype (DroEye) mounted on a drone to demonstrate prominent social cues in Human-Drone Interaction. We describe possible attributes associated with the DroEye prototype and our future research directions to enhance the overall experience with social drones in our environment.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.Publication Metadata only Robo2Box: a toolkit to elicit children's design requirements for classroom robots(Springer-Verlag Berlin, 2016) Barendregt, Wolmet; Department of Mechanical Engineering; Department of Media and Visual Arts; N/A; Department of Psychology; Obaid, Mohammad; Yantaç, Asım Evren; Kırlangıç, Güncel; Göksun, Tilbe; Undergraduate Student; Faculty Member; Master Student; Faculty Member; Department of Mechanical Engineering; Department of Media and Visual Arts; Department of Psychology; 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; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 52621; N/A; 47278We describe the development and first evaluation of a robot design toolkit (Robo2Box) aimed at involving children in the design of classroom robots. We first describe the origins of the Robo2Box elements based on previous research with children and interaction designers drawing their preferred classroom robots. Then we describe a study in which 31 children created their own classroom robot using the toolkit. We present children’s preferences based on their use of the different elements of the toolkit, compare their designs with the drawings presented in previous research, and suggest changes for improvement of the toolkit.Publication Metadata only Social drone companion for the home environment: a user-centric exploration(Assoc Computing Machinery, 2017) Karjalainen, Kari Daniel; Romell, Anna Elisabeth Sofia; Ratsamee, Photchara; Fjeld, Morten; Obaid, Mohammad; Department of Media and Visual Arts; Yantaç, Asım Evren; Faculty Member; Department of Media and Visual Arts; College of Social Sciences and Humanities; 52621Recent 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.Publication Metadata only Virtual collaboration tools for mixed-ability workspaces: a cross disability solidarity case from Turkey(Assoc Computing Machinery, 2023) Department of Media and Visual Arts; Yıldız, Zeynep; Subaşı, Özge; Department of Media and Visual Arts; Graduate School of Social Sciences and HumanitiesA growing body of literature on mixed-ability teams within HCI investigates how disabled and non-disabled people collaborate. Still, how diferent disabilities can interact in a mixed-ability team is underexplored, especially for long commitments and in non-western contexts. As an emerging perspective in accessibility studies in HCI, disability justice emphasizes the importance of cross-disability collaborations. Collaborative access, interdependence, and crossdisability dialogue are keys to building accessible mixed-ability interactions. We conducted ten in-depth interviews with the members of a unique mixed-ability team (which includes people with diferent physical disabilities) using the same workspace with crossdisability interactions in Turkey. We aim to understand the requirements for an accessible mixed-ability virtual workspace and to identify practical design considerations for cross-disability solidarityoriented virtual collaboration tools. To ensure equal access in virtual workspaces, we suggest implications for centering collective access, balancing external power dynamics, and supporting language and cultural diversities.
