In this paper, we propose a framework for engineering drawings recognition using a case-
based approach. The key idea of our scheme is that, interactively, the user provides an …

Existing Chinese educational software tools teach the students at the primary or
kindergarten levels the stroke movements and stroke order of each Chinese character by …

An dieser Stelle möchte ich mich bei all jenen bedanken, die zum Gelingen dieser Arbeit
beigetragen haben. Meinen besonderen Dank gilt meinen Doktorvater Herrn Prof. Dr.-Ing …

In this paper, a graph constructive approach to solving geometric constraint problems is
being described. Usually, the graph constructive approach is efficient; however, it has its …

Modeling by constraints enables users to describe shapes by specifying relationships
between geometric elements. These relationships are called constraints. A constraint solver …

In computer-aided design, geometric modeling by constraints enables users to describe
shapes by relationships, called constraints between geometric elements. The problem is to …

Geometric constraint solving has applications in many different fields, such as computer-
aided design, molecular modelling, tolerance analysis, and geometric theorem proving …

Reasonable task planning is the key technique to improve cooperation quality and the
design efficiency in collaborative design. This paper proposes the concept of Task …

Online graphics recognition has become the key problem for pen-based user interface on
small screen devices, such as PDA and Tablet PC. In this paper, a novel constraint-based …

In computer aided design, geometric modelling by constraints enables users to describe
geometric objects by geometric constraints. Many resolution methods have been proposed …
