In the civil engineering field of Japan, enabling public involvement is thought to be as a key factor to make better plans, systems and the infrastructures themselves, as well as to be supported by the taxpayers. In spite of the expectation, the process guideline issued by the government states processes reflecting users’ (in this case residents’ and public's) opinions only into the conceptual plans and thus the findings are not reflected to later project processes. In this study, Japan’s infrastructure project processes are first introduced to figure out the characteristics of stakeholders and project processes. Then preceding studies in the field are reviewed to understand the needs and obstacles in terms of applying the Human-centered Design processes and methodologies to obtain better plans. As the result of the review, issues are raised that considerations are necessary to fit the characteristics of infrastructure planning such as longer and larger project size, and less dense interaction with the users.

Designing an attractive new service is a difficult task. Researchers have developed various tools that can help designers become more efficient in the field of the service design. In practice, however, de­signing an attractive service raises unforeseen problems that hinder progress in the project. Actual projects often become delayed or diverted. This paper introduces a case-study that reveals the true progression of a project in the early stage of service design. We adopt the ethnographic approach in observing a project for four months. We particularly focus on the causes of problems that cause delay and diversion of the design iteration. In addition, we develop a novel method and tool to support service design based on insights of the observation result by utilizing human-centered design process. Our tool allows a designer to iteratively design a service concept easily and quickly in the early stage of service design based on a storyboarding. Furthermore, this case study suggested the effectiveness of human-centered design process for developing a novel method to support service design.

In recent years, gesture UIs are developed for variety of situations. However, they still have problems of lack in usability. To challenge this problem, we have developed a prototype of gesture UI system using Leap Motion. We have experimented pleasurable sensations occurred from the interaction between gestures and visual feedbacks from both aspect of design and engineering. Thus, we have found out that pointing-oriented UI design, which users point at an operation object in a given time, improves the usability. In our research, we propose a design guideline for improving usability of gesture UIs and which consist of UI design, interaction design, knowledge for developments which we have gained through prototyping processes.
