[modifier] GVT

While the use of real equipment for training in maintenance procedures imposes many constraints, these can be alleviated by the use of virtual reality. The GVT (General Virtual Training) project provides a full platform that can be used to build virtual training environments.

[modifier] Introduction

The GVT project is developed in a Research/Industry collaboration, with three partners: INRIA and CERV laboratories, and Nexter group. This last partner is an important French company, specialized in military equipments such as the Leclerc tank.

GVT is now an operational multi-user application with about 60 real industrial scenarios on 7 Nexter equipments. The main current application of GVT (the first release which is under commercialization) is virtual training on Nexter maintenance procedures, but GVT allows virtual training on more general procedures, such as starting procedures, showing procedures, diagnosis procedures.

In a typical training session, a trainer supervises several trainees. Each trainee, on his own computer, trains alone on one of the available procedures. The trainees and the trainer do not need to be co-located, they simply need to be on a common network.

The paradigm of interaction in GVT is based on the selection of objects. A dynamic menu then appears so that the trainee can select the action to perform. This is a convenient choice to standardize the interaction.

Furthermore GVT uses OpenMASK for VR aspects. The use of this platform makes GVT totally independent from interaction devices which are managed by OpenMASK. Thus, different hardware configurations are available: from a fully immersive room to a laptop, including a dual-screen desktop computer. The peripherals used vary with the hardware configuration, but the software remains the same.

In an immersive room, we can manage stereovision, speakers with voice synthesis (ex: to inform the trainee about the next action to perform), a microphone with voice recognition (ex: to change the viewpoint), a tracker which handles a pointer in the environment, and a dataglove to make the selection. On a laptop, a trainee can simply use the keyboard and the mouse to interact. For example, if speakers are not available, the voice synthesis is automatically replaced by text on the screen.

[modifier] GOSE

Gose is an Ogre Scene Editor made with gtkmm. The aim of gose is to be extended by user Plug-In. To do so we provide some xslt code generation from glade xml files to Gose Plug-in. Look at the architecture page for more information. It's a cross plateform LGPL tool (For linux and Windows) Currently features :
