The authors formulate the class responsibility assignment (CRA) problem as the fuzzy constraint satisfaction problem (FCSP) to automate CRA, and show the results of automatic assignments of examples. Responsibilities are contracts or obligations of objects that they should assume; by aligning them to classes appropriately, quality designs realize. Typical conditions of a desirable design are having a low coupling between highly cohesive classes. However, because of a trade-oﬀ among such conditions, solutions that satisfy the conditions moderately are desired, and computer assistance is needed. The authors represent such conditions as fuzzy constraints, and formulate CRA as FCSP. That enables to apply common algorithms that solve FCSP to the problem, and to derive solution representing a CRA.

We propose an application that analyzes and visu-alizes electrocardiogram and plethysmogram data; it offers a user interface enabling users to browse the data checking their relation, for brief assessment of autonomic nervous activity (ANA). Our application enables users to traverse analyzed data seamlessly, and helps them comprehend the transition of ANA.
We developed a system that, using mobile devices (smart phones and tablets etc.), represents virtually a larger display than those of the devices before users' eyes. It is realized by updating display screens of the devices following devices' orientation sensed by embedded sensors. By comparison with existing scrolling operation by touching displays, our method might be intuitive and easy to comprehend whole contents presented in displays because the method entails body motion. We introduce two types of Android application to incorporate our concept.
