We introduce an intuitive gesture-based interaction technique for creating and manipulating
simple three-dimensional (3D) shapes. Specifically, the developed interface utilizes low-cost …

This paper presents an innovative, portable, and low cost system for fast and interactive
design of sketched models using 3D curve networks. The system is based on a stereo …

Dynamically changing the machining condition and uncertain manufacturing resource
availability are forcing the computer-aided process planning system to enhance the …

The die model characterized with high design efficiency and strong correlation plays an
important role in simulation and machining. Because of the complexity of structure and the …

With increasing demand in design, most of the industrial designers or engineering designers
are facing the challenge to make timely sustainable design decisions in their design …

Designer thinking has received much attention as an innovative problem-solving approach.
However, it is also a vague and unclear activity which can only be studied through the input …

In accordance with the fundamental principles and methods of Human-Computer Interaction
(HCI), this paper has explored the design process and methods on modeling technique of …

The standard CAD tools allow great degree of control in 3D shape creation by requiring the
user to specify exact shape parameters in a highly structured manner. However, that …
