Although there has been a drastic increase in the research of aesthetics of interaction, we still lack well-defined practical knowledge of how to <i>design</i> aesthetic interactions. In order to develop such knowledge, we adapt three important ways of thinking in designing <i>interactions</i> influenced by traditional design disciplines, namely, 1)(More)
Peripheral expressions using various modalities are considered as possible alternative ways of delivering information in our communication. In this research, we aimed to explore how the thermal expression can be used in the interpersonal communication. Based on the result of the focus group interview, we developed a pair of devices with which the users can(More)
We describe a study that investigated how a shared interactive tabletop (DiamondTouch) can be designed to provide new opportunities for supporting collaborative decision-making. Small groups of users were required to work together using the table by selecting and placing digital images into a calendar template and justifying their choices to one-to-another.(More)
The role of prototypes is well established in the field of HCI and Design. A lack of knowledge, however, about the fundamental nature of prototypes still exists. Researchers have attempted to identify different types of prototypes, such as low- vs. high-fidelity prototypes, but these attempts have centered on evaluation rather than support of design(More)
This paper reports the highlights of a user study which gauges reactions to a variety of common “trust indicators” – such as logos, third party endorsements, and padlock icons – over a selection of authentic and phishing stimuli. In the course of the think-aloud protocol, participants revealed different sensitivities to email messages and web pages. Our(More)
We propose a new perspective, seeing interactivity that is the immaterial part of an interactive artifact as something concretely describable and perceivable as we do with physical materials. In order to examine the validity of this proposal, we extracted a set of interactivity attributes to be used as a design language for thinking and describing(More)
Many traditional methods in the task analysis area are developed for analyzing the task structure of interactions involving individual users. Nowadays more issues have been raised in dealing with group work task analysis. Accommodating contextual information as a part of task modeling is a potentially fertile arena of exploration in this area. This paper(More)
It has always been challenging for designers and developers to readily pinpoint potentially viable opportunities for emerging technologies in people's daily lives. In ubiquitous computing in particular, the uncontrollable dynamics of a user's context makes this issue even more prominent. In this article, the authors assume they can't hypothesize what users(More)
