ジャーナル フリーThis paper focuses on the recent trends of researches on diagrammatic reasoning, especially reseaches on the use of diagrams in thinking and problem solving. First, two important issues relevant to the research field were identified. Then, the recent studies in the field were classified into three types: the study of human diagrammatic reasoning, that of computational facilitation of human diagrammatic reasoning, and that of computational models of diagrammatic reasoning. All the types of studies were explained in terms of the indentified issues, with some typical cases.抄録全体を表示PDF形式でダウンロード (1098K) -

ジャーナル フリーThe purpose of this study was to examine the usefulness of vector representations, diagrams constructed of geometric vectors, in statistics training. In 2 experiments, the effect of using the vector representations was compared with the conventional, algebraic method. In the preliminary experiment, 4 graduate students solved a problem about the regression analysis in both of the two ways. Only one student was able to solve the problem by using algebraic method. All the students succeeded in solving the problem with the vector representations. In the second experiment, 15 undergraduate students learned a text material on the regression analysis and solved three problems about this analysis. The vector representations sometimes helped the students learn the text material and solve the problems. However, these representations were not always useful. Three properties which made the vector representations useful were found: reducing the number of solution steps, easy and concrete manipulations, and a small number of operators. It is argued that students can easily learn statistics only when these properties help them.抄録全体を表示PDF形式でダウンロード (1220K) -

ジャーナル フリーWhen a person works in spatial workspace with his or her partner at the remote site, they encounter many difficulties that they never encounter when they work together at the same place. We address one of the known difficulties in distributed spatial workspace collaboration—disagreement of observational viewpoint. We propose a framework to analyze the problem related to disagreement of viewpoints. According to our framework, the cognitive load to align between the view of the other site and the view of the real workspace disturbs their communication and efficiency of their work. We analyze some problems about disagreement of observational viewpoint in distributed spatial workspace collaboration and functions of some groupware systems. Moreover, we develop a support system for distributed spatial workspace collaboration. The system automatically aligns one's reference frame and that of other site. The system is expected to reduce the cognitive load to align the reference frames and to facilitate distributed spatial workspace collaboration.抄録全体を表示PDF形式でダウンロード (3089K) -

ジャーナル フリーAs a mere manual mode of orthographic illustration the axonometric drawing is increasingly treated in terms of its CG equivalent as a more generic form of presentation and its practical methodology seems to remain without sensible renovation. But both forms are basically interactive; with the former more logically tangible, also underlying the art of realism, esp. sketching etc.
The present report aims to help enhance practical utility of axonometric manual drawing routines by auxiliary means as follows.
One is a basic subscheme as a version of the conventional form of rotational transformation of an axonometric coodinate plane ; introduced for easier construction of its true shape, notably when the angle between the axis of rotation and either of relevant two principal axes to be rotated is too small to intersect within the limits of the practicable construction.
The other ancillaries are for the construction of rotation of the reference system so that it may have any designated angle to the visual ray. One such scheme serves to decide a dimetric system symmetrical with respect to one of its lateral principal axes. It has been numerically treated as is the case with DIN's standardized system (i. e. normierte Axonometrie), only to prove herein capable of facile construction.
The rest are two subsystems to help construction of rotation of a principal plane to fill composite requirements for visual angle ; with which to draw ellipses available as standard template configurations, intended to be applicable e.g. to depict circular-sectioned combinations of objects and exemplified by illustrations of intersected solids.抄録全体を表示PDF形式でダウンロード (794K) -
