Abstract

In collaborative engineering, different engineers or organizations collaborate to achieve the goal of planning and accomplishing an engineering task. Collaborative engineering covers not only the technical aspects of building a product, but also management issues, such as planning, scheduling, and budgeting. It is essential for the collaborators to come together periodically in the form of a conference to discuss urgent matters and to make decisions. However, collaborators are often spread over vast geographical distances making these attempts of holding a conference difficult, if not altogether impossible. In this paper, we present "Computer-Mediated Collaborative Engineering System" (CMCES) that we have designed to conduct online collaborative engineering meetings, and to aid the various phases of collaboration engineering. The purpose of CMCES is twofold -- to hold an online collaborative engineering meeting and to support the various stages in collaborative engineering that is done in a distributed environment. CMCES is chiefly used in synchronous mode, but it can be used asynchronously as well. There are commercially available video conferencing systems, but CMCES is designed to support distance collaborative engineering stages from the planning to product-making, viz., planning, designing, scheduling and prototyping. CMCES also stands for Computer-Mediated Collaborative Educational System. The same features that are used for distance collaborative engineering can be used for distance education. Real in-depth learning takes place in a collaborative setting, where the students take the lead in teaching one another in the presence of the instructor rather than being in a position of receiving passively from the instructor. The salient features of CMCES support the teacher-students interaction, students-teacher interaction and students-students interaction that comprise a sound collaborative pedagogy. CMCES is a low-cost and user-friendly online system with whiteboard, text, audio and video functions. It is built by using Visual Basic and Direct X. Direct X can be downloaded free of charge from Microsoft and can be run in the Windows environment. CMCES can be easily executed on Windows platform.
