3D object selection and manipulation is one of the essential features for any augmented reality (AR) system. However, distant object selection and manipulation still suffer from lack of accuracy and precision. This paper introduces an alternate 3D interaction technique for selection and manipulation distant 3D object in in immersive video see-through AR. The proposed interaction technique offers a...
Nowadays, collaborative systems and applications are widely used to allow multiple users to work together in order to achieve one same goal. In the field of virtual and augmented realities, such collaboration is often sought to effectuate complex activities in some relevant experiences. Users can share virtual objects, but most importantly, they use collaborative 3D interaction, visualize their objects...
In this paper, we present an improved version of MOBIL descriptor [1] (Improved MOments based BInary differences for Local description), which introduces two main contributions. The first one is the use of geometric information for the binary test instead of the classical intensity binary test, to get more precision in the description step. The second one is to attribute two bits for each test, to...
In this paper we present an extended formalism of web services for developing a Remote Collaborative Manipulation system in Augmented Reality Environment. This system is an Internet-based virtual 3D environment that provides users a shared space and a collaborative platform for publishing, simulating and analyzing multidimensional data. In this paper, we have constructed our collaborative system using...
The use of renewable energy is growing significantly around the world. In front of the growing demand for electricity principally for the remote and isolated areas, photovoltaic systems, especially water pumping systems, begin to find great applications. Unfortunately, these systems have faced a number of problems even nowadays: a problem of maintenance and repair. Augmented Reality (short: AR) seems...
Techniques that enable user interaction with a mixed environment in natural way and low-cost may provide a great potential to increase the degree of virtual presence. In this paper, we present a low-cost 3D interaction technique based on ARToolKit planar marker in order to interact with mixed reality environment, and manipulate 3D virtual object. This proposed method that we called “2 in 1 Marker”...
In this paper, we propose an efficient, and fast binary descriptor, called MOBIL (MOments based BInary differences for Local description), which compares not just the intensity, but also sub-regions geometric proprieties by employing moments. This approach offers high distinctiveness against affine transformations and appearance changes. The experimental evaluation shows that MOBIL achieves a quite...
In the industry, complex technologies are introduced to improve the productivity. Because of the maintenance tasks can be very complex, technicians can be assisted by remote experts to perform their physical tasks. Maintenance can be supported by augmented reality technology that directly links instructions on how to perform maintenance tasks. This paper presents a real time collaboration system for...
In order to stabilize water supply for remote regions and deserts, it is not only necessary to improve the power generation system, but also to improve its maintenance strategy. Photovoltaic pumping systems need to be maintained periodically. Both maintenance efficiency improvement and reduction of its cost are desired. Augmented Reality (AR) is one of the promising technologies that will be able...
The objective of this work is to introduce Augmented and Mixed Reality technologies in aquatic leisure activities. We have proposed a new device which is autonomous, mobile and easily transportable by one person. It can also be easily installed, equipped with GPS and wireless systems, and has positive buoyancy. The device will be used at water surface as well as underwater using a tuba. Moreover,...
In this paper, we present an interactive tabletop based on hand gesture recognition, In this case, we propose a method based histogram for hand detection and extraction. For gesture recognition we propose a scale and rotation invariant method merging Chain Code algorithm and modified approximate string matching method. With this developed system, the user can perform different gestures as zoom, move,...
The rapid evolution of technologies and interaction devices has enabled the emergence of interactive systems merging real and virtual worlds. These systems are characterized by new interaction forms. They involve new constraints that must be considered in the development process. This paper presents a set of elements and concepts to design augmented reality systems. The aim is to integrate human-computer...
This paper, presents a tracking technique based on both detection Color marker and a least squares method. The objective is to estimate the perspective transformation matrix for the current view of the camera. This technique does not require any information or computation of the camera parameters; it can be used in real time without any initialization and the user can change the camera focal without...
In this paper, a hand gesture recognition method based on color marker detection is presented, In this case, we have used four types of colored markers (red, blue, yellow and green) mounted on the two hands. With this posture the user can perform different gestures as zoom, move, draw, and write on a virtual keyboard. This implemented system provides more flexible, natural and intuitive interaction...
