    Re-reading design: cultural analogies for inspiration in interaction design
    (Deniz Yengin, 2018) N/A; Department of Media and Visual Arts; Güzererler, Ahmet; Özcan, Oğuzhan; 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); N/A; College of Social Sciences and Humanities; N/A; 12532
    Designers systematically seek inspiration from various sources from different domains and expand their repertoire of paradigms to foster their designs. However, designers usually do not explore the full potential of their inspiration sources by establishing surface level and close domain analogies regardless of their experience. We think that the process of finding deep and distant domain analogies could be made more understandable for novice designers and less time consuming for professionals with an inspiration/ideation practice for innovation. We discovered that decontextualizing the inspiration source and deconstructing its perceived meaning into fragments lead designers to explore new connections with inspiration source and discover new inspirational points. Here, in this paper, we re-introduce our re-reading in design practice from our previous studies and examine whether it can be a complimentary inspiration/ideation practice for designers to deconstruct conventional paradigms and create deep and distant domain analogies more comfortably. / Öz: Tasarımcılar ilham bulmak için sistematik bir şekilde çeşitli alanlardan kaynaklar kullanmakta ve paradigma dağarcıklarını genişletmektedirler. Fakat tasarımcılar genelde bu süreçte ilham kaynaklarıyla yüzey düzeyi ve yakın alan analojileri kurmadıkları için fikirlerinin tam potansiyelini keşfedememektedirler. İlham kaynağını bağlamından bağımsız değerlendirerek ve anlamını yeniden inşaa ederek tasarımcıların esinleninen ile yeni bağlantılar ve yeni ilham noktaları keşfettiğini gördük. İnovasyon için ilham / düşünce uygulaması yapılırken, bu derin ve uzak alan analojileri bulma sürecinin yeni tasarımcılar için daha anlaşılır, profesyoneller için ise daha az zaman gerektiren bir hale getirilebileceğini düşünüyoruz. Bu yazıda, daha önceki çalışmalarımızdan olan tasarım pratiğinde yeniden okuma’yı baştan tanıtıyor ve bunun ilham / düşünce uygulamasında tasarımcılara geleneksel paradigmaları bozmak, derin ve uzak alan analojileri daha rahat bir şekilde kurmalarındaki etkisini inceliyoruz.

    Perception of skin stretch applied to palm: effects of speed and displacement
    (Springer International Publishing Ag, 2016) Provancher, William R.; N/A; Department of Mechanical Engineering; Güzererler, Ahmet; Başdoğan, Çağatay; Researcher; Faculty Member; Department of Mechanical Engineering; KU Arçelik Research Center for Creative Industries (KUAR) / KU Arçelik Yaratıcı Endüstriler Uygulama ve Araştırma Merkezi (KUAR); N/A; College of Engineering; N/A; 125489
    Skin stretch is a powerful haptic effect with a great potential as a feedback mechanism for digital gaming applications. For example, it has been shown to communicate directional information accurately to game players. However, the existing devices apply stretch to the tip of index finger except the Reactive Grip game controller by Tactical Haptics, which applies skin stretch to a user's palm and finger pads. We have designed a compact hand-held haptic device that applies skin stretch to the palm via an actuated tactor. Compared to the fingertip, the palm is slightly less sensitive to skin stretch but affords larger stretch area. The stretch area of the palm enables us to control both tactor displacement and speeds for a broader range, resulting in richer haptic feedback. Using this device, we conduct experiments with 8 participants to investigate the effects of tactor displacement, speed, direction and hand orientation on perceived magnitude of skin stretch. The results of the study show that not only the tactor displacement but also the speed has a significant effect on the perceived intensity of skin stretch and the mapping function between them is nonlinear. Moreover, it appears that the tactile sensitivity of human palm to skin stretch is not homogeneous and stretch applied to the radial aspect of palm (towards the thumb) results in higher intensity than that of ulnar aspect.
