SKETCHING IN VIRTUAL REALITY FOR RAPID AND SITUATED IDEA GENERATION
Minjoo Cho,Bokyung Lee,Joonhee Min,Daniel Saakes 한국디자인학회 2015 한국디자인학회 학술발표대회 논문집 Vol.2015 No.10
We introduce a sketch-based 3D modeling system using Virtual Reality (VR) with a Head Mounted Display (HMD). The system enables users to sketch freely 3D objects in various colors, arrange and situate the objects in the environment and finally export the virtual objects into a 3D file for fabrication. We evaluated the system in a small workshop with users, and the system was found to have a possibility for rapid ideation and for spatially conceptualizing ideas.
''See me, feel me'': Effects of 3D-printed surface patterns on beverage evaluation

<P>Research shows that packaging appearance can have a strong impact on taste experience and product evaluation. However, so far research has mainly focused on how visual appearances may steer sensory impressions including smell and taste. Taking into account new (technological) developments which allow for consideration of a wide range of previously unexplored packaging factors, the research presented here investigates the impact of 3D-printed surface patterns on taste evaluations as a function of product type (a bitter tasting coffee versus a sweet tasting chocolate.drink) and verbal product claims (either stressing taste strength or taste softness). To this end, 3D-printed cups with angular and rounded surface patterns were manufactured and handed to shoppers participating in a taste session for a fictitious coffee or chocolate brand. Results show that an angular surface pattern increased perceived bitterness and taste intensity ratings, whereas a rounded surface pattern induced a sweeter taste evaluation and a less intense taste experience. Congruent pairings of drinks and tactile patterns resulted in more favorable outcomes. Finally, congruence was also found to be important with respect to taste descriptions, with verbal claims in line with surface pattern associations further enhancing product experience.

미래의 패브리케이션 인터페이스를 위한 두 가지 디자인 프로세스 사고 과정
박준동(Jundong Park),이보경(Bokyung Lee),한결(Gyeol Han),석다니엘(Daniel Saakes) 한국HCI학회 2017 한국HCI학회 학술대회 Vol.2017 No.2
디지털 패브리케이션은 HCI 에 새롭게 떠오르는 화두이다. 일반인이 스스로 자신의 물건을 커스터마이징(Customizing) 할 수 있도록 도와주는 패브리케이션 도구나 인터페이스에 대한 연구는 그간 있었으나 대부분이 미리 정해진 과제, 색깔을 선택하거나 크기를 숫자로 설정하는 데 그쳐왔다. 본 연구는 사용자들이 자신의 이상적인 가구를 어떻게 생각하고 또 묘사하는지를 이해하고자 하며, 그러한 생각이 기존에 가지고 있던 물건과 어떤 관계를 맺는지에 대해서 더 탐구하고자 한다. 이를 위하여 우리는 사용자들이 각자의 집에서 가구에 대해 평소에 어떻게 생각하는지를 알아보았다. 본 연구의 결과는 사용자가 기존의 가구를 평가할 때와 미래의 가구를 묘사할 때의 사고 과정이 차이가 있다는 사실을 시사하며, 향후 미래의 패브리케이션 인터페이스를 제작하는 데 있어 두 가지 사고 과정이 모두 고려되어야 한다는 점을 보여준다.

<P><B>Abstract</B></P> <P>Research shows that design factors of packaging and food containers can have a strong impact on taste experience and product evaluation. However, so far research has mainly focused on how visual appearances steer sensory impressions including smell and taste. Taking into account new (technological) developments in packaging design, this research investigates the impact of 3D-printed surfaces on taste evaluation of two ice cream variants. In addition, the interplay between surface textures and matching or non-matching shapes presented on a poster in the consumption environment (i.e., an ice-cream salon) was studied. To this end, 3D-printed cups with either a sharp or smooth surface were manufactured and used in a taste session conducted at an ice-cream salon, where either a poster with sharp or smooth shapes was hanging down the wall. Results testify to the potential of influencing taste evaluations by means of surface textures, with a smooth surface enhancing sweetness evaluation, and a sharp surface enhancing intensity evaluations. Furthermore, findings might imply that mismatches between surface textures and poster design may enhance product and taste liking.</P> <P><B>Highlights</B></P> <P> <UL> <LI> 3D-printed surface textures can accentuate basic taste sensations such as sweetness and sourness. </LI> <LI> A sharp surface texture can enhance overall taste intensity. </LI> <LI> Subtle mismatches between surface texture and poster design may enhance ice cream liking. </LI> <LI> The embodied cognition framework can provide explanations for meanings connoted by design elements. </LI> </UL> </P>
