The paper shows how mechanisms of existing modeling languages (exemplified by UML 2.0) support the direct modeling of variability in software product lines/system families, and identifies where generative modeling (similar to generative programming) should be applied. Existing mechanisms are not only well-known mechanisms like composition, specialization, and generics/templates, but also less k...

Direct manipulation is the operation in which users' operations directly invoke the reaction of the system (Shneiderman 1986). We apply the direct manipulation technique to operate a three-dimensional object. Some works on editing a three-dimensional object by using the direct manipulation technique have been proposed. But they require a special input device. We think it is beneficial to make u...

A method for integrating constraints and interactive manipulation for three dimensional design is discussed. Constraints are specified and maintained interactively and the results of each operation presented immediately to the user. Partially constrained objects may be interactively dragged and constraints propagated throughout the scene in real time to reflect changes. The techniques have been...

Two beliefs, ease of use and usefulness, have been considered to be fundamental in determining the acceptance of various IS in the past decades. These beliefs may not, however, fully explain the users’ behavior in an emerging environment such as Internet banking. In this study, we introduce trust as another belief that has an impact on the acceptance of Internet banking. We collected 845 cases ...

As the most active plateau on the Earth, the Qinghai-Tibet Plateau (TP) has a complex crust–mantle structure. Knowledge of the distribution of such a structure provides information for understanding the underlying geodynamic processes. We obtain a three-dimensional model of the density of the crust and the upper mantle beneath the TP and surrounding areas from height anomalies using the Earth G...

In this paper we present an environment for conceptual design which mimics the interaction of designers with physical mockups. We present novel three dimensional on-and-above-the-surface interactive techniques which combine asymmetric bimanual operations with multi-touch direct manipulation on a flat surface and depth cameras. These take advantage of a continuous interaction space to create and...

Repetitive processes are a distinct class of 2D systems (i.e. information propagation in two independent directions) of both systems theoretic and applications interest. They cannot be controlled by direct extension of existing techniques from either standard (termed 1D here) or 2D systems theory. Here we give new results on the design of physically based control laws and, in particular, the fi...

This paper describes a method for manipulating a threedimensional object without considering conventional three independent orthogonal views. We apply the direct manipulation to operate the three-dimensional object. We propose “augmented manipulation” which is an enhanced direct manipulation technique by using additional information. We implement three-dimensional modeling tool “Claymore” by us...
