    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; Department of Media and Visual Arts; Çay, Damla; Yantaç, Asım Evren; PhD Student; Faculty Member; 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.

    It made more sense: comparison of user-elicited on-skin touch and freehand gesture sets

    Research on gestural control interfaces is getting more widespread for the purpose of creating natural interfaces. Two of these popular gesture types are freehand and on-skin touch gestures, because they eliminate the use of an intermediary device. Previous studies investigated these modalities separately with user-elicitation methods; however, there is a gap in the field considering their comparison. In this study, we compare user-elicited on-skin touch and freehand gesture sets to explore users' preferences. Thus, we conducted an experiment in which we compare 13 gestures to control computer tasks for each set. Eighteen young adults participated in our study and filled our survey consisted of NASA Task Load Index and 4 additional items of social acceptability, learnability, memorability, and the goodness. The results show that on-skin touch gestures were less physically demanding and more socially acceptable compared to freehand gestures. on the other hand, freehand gestures were more intuitive than on-skin touch gestures. Overall, our results suggest that different gesture types could be useful in different scenarios. Our contribution to the field might inspire designers and developers to make better judgments for designing new gestural interfaces for a variety of devices.

    A novel tactile sensor for detecting lumps in breast tissue
    (Springer-Verlag Berlin, 2010) Güçlü, Burak; Yıldız, Mustafa Z.; N/A; Department of Mechanical Engineering; Department of Mechanical Engineering; Ayyıldız, Mehmet; Başdoğan, Çağatay; Master Student; Faculty Member; Graduate School of Sciences and Engineering; College of Engineering; N/A; 125489
    We developed a compact tactile sensor in order to guide the clinician or the self-user for non-invasive detection of lumps. The new design has an advantage over the existing discrete tactile sensors and detection methods by efficiently sensing force distribution over an area without any side effects. The sensor consists of 10x10 infrared emitter-detector pairs, a silicon-rubber elastic pad, and a contoured tactile interface (25x21 moving pins) for palpating three-dimensional objects. To demonstrate the practical use of the sensor, first a cylindrical tissue-like silicon phantom was prepared, then a 13 mm diameter rigid spherical object was placed at varying depths of 0-20 mm to simulate cancerous lumps in breast tissue, and finally the tactile sensor was systematically pressed on the phantom to successfully detect the lumps for compression depths of I 024 mm. The location and the estimated radius of each lump were calculated from the recorded tactile images.
