GRAPP'12:An Occlusion-Aware AR Authoring Tool for Assembly and repair tasks

Gimeno, Jesús; Morillo, Pedro; Orduña, Juan Manuel; Fernández, Marcos

(2012). Article

Full article.

The use of authoring tools has become a valuable trend for the fast development of Augmented Reality (AR) applications in industrial organizations. However, most of current AR authoring tools are actually programming interfaces that are exclusively suitable for programmers. Moreover, they do not provide advanced visual effects, such as occlusion or object collision detection, to the resulting AR applications. In this paper, we propose an easy-to-use AR authoring tool oriented to the development of AR applications for the execution of industrial sequential procedures. Unlike other recent easy-to-use AR authoring tools, this software framework allows non-programming users to develop low-cost...

The use of authoring tools has become a valuable trend for the fast development of Augmented Reality (AR) applications in industrial organizations. However, most of current AR authoring tools are actually programming interfaces that are exclusively suitable for programmers. Moreover, they do not provide advanced visual effects, such as occlusion or object collision detection, to the resulting AR applications. In this paper, we propose an easy-to-use AR authoring tool oriented to the development of AR applications for the execution of industrial sequential procedures. Unlike other recent easy-to-use AR authoring tools, this software framework allows non-programming users to develop low-cost AR applications, including occlusion capabilities, by means of the use of a Kinect sensor. These applications could be used in on-site assembly and maintenance/ repair tasks where a certain level of depth perception is needed. In order to validate our AR authoring tool, we have developed four AR applications belonging to different industrial areas. The evaluation results show that overlaying 3D instructions on the actual work pieces reduces the error rate for an assembly task by more than a 75%, particularly diminishing cumulative errors common in sequential procedures. Also, the results show that the time required by non-programming users to develop the AR prototypes using our tool was more than 90% lower than the time required for developing the same prototypes with computer graphics programmers. These results show the potential of our approach and validate the tool as a general-purpose AR authoring tool for industrial AR applications

GRAPP'12: On the Real-time Physics Simulation of a Speed-Boat Motion

Casas, Sergio; Rueda, Silvia; Riera, José V.; Fernández, Marcos

(2012). Article

Full article.

Training necessities on watercraft have increased during the last few years and real-time simulators offer a suitable and safe alternative. However, the design of a real-time watercraft simulator implies that, water simulation and water-vehicle interaction have to be addressed efficiently. This paper presents a simplified physics model of the water-vehicle interaction for real-time speed-boat simulators that run over 6-DOF motion platforms. The proposed model is highly parametrizable and can be adapted to any speed-boat by changing the values of the parameters. We propose the evaluation of the designed model in a quantitative and a qualitative way. Evaluations results show that the proposed...

The proposed model is highly parametrizable and can be adapted to any speed-boat by changing the values of the parameters. We propose the evaluation of the designed model in a quantitative and a qualitative way. Evaluations results show that the proposed model behaves like a real one in terms of both objective trajectories and subjective perceived experience.

GRAPP'12: A Kinect-Based Augmented Reality System for Individuals with Autism Spectrum Disorders

Casas, Xavier; Herrera, Gerardo; Coma, Inmaculada; Fernández, Marcos

(2012). Article

Full article.

In this paper an Augmented Reality system for teaching key developmental abilities for individuals with ASD is described. The system has been designed as an augmented mirror where users can see themselves in a mirror world augmented with virtual objects. Regarding the content the tool is designed with the aim of facilitating the acquisition of certain skills in children with ASD. From a technical point of view, it has been necessary to solve two problems to develop the tool. The first one has been how to capture the user’s movements, without wearing invasive devices, to animate their virtual avatar. A Kinect device has been chosen. The other problem has been to mix in the augmented virtual...

The system has been designed as an augmented mirror where users can see themselves in a mirror world augmented with virtual objects. Regarding the content the tool is designed with the aim of facilitating the acquisition of certain skills in children with ASD. From a technical point of view, it has been necessary to solve two problems to develop the tool. The first one has been how to capture the user’s movements, without wearing invasive devices, to animate their virtual avatar. A Kinect device has been chosen. The other problem has been to mix in the augmented virtual scene real objects located at different depths. An OSG shader has been developed, of which details will given in this paper.
