Resumen
In this paper, a series of interface tests on interaction approach for the generation of geometric shape designs via multi-sensory user interface of a Virtual Reality (VR) based System is presented. The goal of these interface tests is to identify an effective user interface for VR based Computer-Aided Design (CAD) system. The intuitiveness of the VR based interaction approach arises from the use of natural hand movements/gestures, and voice commands that emulate the way in which human beings discuss geometric shapes in reality. In order to evaluate the proposed interaction approach, a prototy

Resumen
In recent years there have been moves in industrial engineering towards greater automation through intelligent systems and this has resulted in replacing human expertise. In many cases the potential of intelligent systems has yet to be realised. This paper presents and discusses an alternative technological approach, which uses immersive virtual reality (VR) to support engineering design tasks. The approach focuses on the human engineer and acknowledges the importance of human input to the design process.

Resumen
The adoption of Virtual Reality (RV) technologies in prototype design and process revision has contributed to multiple industry areas. Nonetheless, the development of VR systems for engineering is a complex task, as it involves specialized teams handling low-level code development. Given these problems, the goal of this study is presenting a methodology for designing VR, through an Authoring System based on Computer-Aided Design (CAD). The presented methodology provides an easy integration of electric power substation floor plans and Virtual Reality software (VRS), as well as three-dimensional

In this article we propose an architecture for the inclusion and exploitation of semantic aspects in a CAD environment. Our schema focuses on the enhancement and improvement of a commercial (general purpose) CAD system on its Virtual Reality (VR) capabilities. There is a need in combining CAD and semantics in the new generation of computer assisted engineering systems. Usually semantic aspects in traditional CAD applications relay on the user’s tacit knowledge, a fact that slows the learning curve while the user is getting trained with a new tool, no matter if he is an expert in others.

Image-processing technology is widely used in industry for automatic inspection and measurement through the capturing of object images by CCD (Charge-Couple Device) cameras and the built-in algorithms. VR (Virtual Reality) is a high-end user interface that involves real-time simulation and interactions through multiple sensorial channels. Three important characteristics of VR are: immersion, interaction, and imagination which enable the users more direct and useful communications with manufacturing prototyping systems.

Resumen
In innovative industrial companies, collaboration techniques and laboratories have been in use for years. What historically started with teleconferencing instead of business trips has now reached the status of normal tools for interdisciplinary cooperation in these companies with advances in technologies such as PCs and data broadband as well as software such as Computer Aided Design (CAD), Virtual Reality (VR) and Augmented Reality (AR). But the collaboration techniques are often installed in extra rooms, e.g. video conferencing facilities and large VR laboratories. Other technologies such as chat programs can be used by any employee directly at his workplace. Without the use of these techniques, the short development times required today in many industrial sectors cannot be achieved and even remote maintenance of machines at the customer’s would be impossible for machine manufacturers. Within a research project, digital collaboration techniques are inspected and evaluated regarding their suitability for interdisciplinary cooperation in various applications. Collaboration techniques include special hardware for graphic simulations and head-mounted displays for 360∘ visualization of digital objects. Additionally different software for cooperation with graphics, video and conference programs distributed over several locations is tested, evaluated and partly newly developed. The application cases are processes from engineering and for planning of buildings. Based on the requirements determined during the tests, a new user-friendly mobile collaboration environment was developed. This collaboration environment integrates the different technologies of graphic simulation as well as already established methods such as video transmission or video conferencing and chat programs in a suitcase system.
