Nowadays, people have to face many challenges In order to become familiar with all the functionalities of electronical devices. The training process becomes thus essential, especially when we are referring to consumer electronics created for people with disabilities. Our paper presents the importance of training visually impaired people for an advanced sensory substitution device. By using the advantages...
This study aims to provide an overview on the intersection and interaction between architecture, urban modeling, planning fields and computer vision field. The reflection of the methods and approaches of fields such as visual recognition, natural language processing, data mining and data visualization onto architecture and urban studies are investigated and potentials of inter/transdisciplinary encounters...
The visual comfort of human being has been gradually considered in high performance building since the higher living quality and lower energy use requirements. Good lighting layout is more and more important, especially in classroom for the students' vision. The number and location of light sources are traditionally determined by the experimented engineer or technician. However, un-precise results...
Computer simulation of tree development can provide important insight into real world tree behavior. Numerous models have been developed ranging from simple equations to complicated 3D geometrical models that allow for simulation of acquisition and allocation of carbohydrates. We introduce IMapple (Interactively Modeled Apple), a functional structural apple tree model that builds on the source-sink...
In the scope of the article, there is the presentation of the cyber-higher educational environment feasible by the technical innovations appearing rapidly and the investigation of the methods which can be applied successfully in the educational scene of the future. My goal was to create an educational scene suiting to the digital life of the CE generation students-called Z generation and alpha generation...
In this paper we propose an effective and wearable mobility aid for people suffering of visual impairments purely based on 3D computer vision and machine learning techniques. By wearing our device the users can perceive, guided by audio messages and tactile feedback, crucial information concerned with the surrounding environment and hence avoid obstacles along the path. Our proposal can work in synergy...
This paper proposes a multiview synthesis method for autostereoscopic (glasses-free) 3D displays. When a plurality of predetermined viewpoint images is generated from a limited number of input images, background information obscured by a foreground object in the input images may be represented by a hole in a new viewpoint image. The proposed method can restore the hole in the image while leaving structural...
Software evolution is supported by a variety of tools that help developers understand the structure of a software system, analyze its history and support specific classes of analyses. However, the increasingly distributed nature of software development requires basic repository analyses to be always available to developers, even when they cannot access their workstation with full-fledged applications...
In this paper, we present a novel 3D interaction technique using a smartphone for large screen such as TV and projector screen. Using our 3D interaction technique, we could manipulate 3D objects in 3D environment with the virtual hand metaphor. Also, we evaluate the effects of various sensory inputs such as vibro-tactile, auditory and visual inputs. The result of the user study shows that visual feedback...
This paper presents the result of the work achieved in the frame of three successive European Projects, which aimed to build an innovative system to assist security managers in the crisis preparation, training and management phases. The iterative approach of the consortium is presented, as well as the results. A novel interactive and shared Common Operational Picture is proposed which has been validated...
The dynamic disparity influence on visual comfort is studied through the subject evaluation designed with the stereoscopic videos captured in studio and natural environments. The technique of zoom was used with three variables to obtain the video sequences. Experiment results showed that dynamic disparity would bring some discomfort to observers, but it was tolerable. Among the three variables, the...
In an open Trusted Desktop Grid system, users can voluntarily participate in order to share resources. Thereby, computational trust is used to isolate malicious agents. Since a fully self-organised solution can suffer in emergent situations like the trust-breakdown scenario, we investigate an additional normative entity to guide the overall system behaviour by still keeping the autonomy of all agents...
A normalized tone-mapping method that can reproduce a 3DTV image with an improved color sensation is proposed. This method uses 128 levels of gray-scale images to measure the RGB tone-curves in both 2D and 3D modes and then models the curves using a piece-wise linear form. To compensate the difference between these two tone-curve models, tone-mapping operators are generated. In addition, the tone-mapping...
Visual saliency has been studied extensively in the past decades through perceptual studies using eye tracking technologies and 2D displays. Visual saliency algorithms have been successfully developed to mimick the human ability to quickly spot informative local areas in images. This paper proposes to investigate the extension of visual saliency algorithms to media displayed in 3D. We show first that...
In this work, we study the understanding of 3D visual objects which are generated by augmented reality techniques. 3D glasses are typically highly priced, and so they are not purchasable for most consumers. Instead, we consider low-priced red-cyan (anaglyph) glasses. We generate the left and right views so that they are comfortable for human eyes.
With the increased availability and affordability of three dimensional visualization and additive manufacturing tools, the opportunity to bring these technologies into the classroom has never been greater. Utilizing 3D scanners, 3D modeling software and 3D printers in the classroom opens the door for hands-on STEM and STEaM education. This paper outlines methods and approaches to introduce these technologies...
With the growing relevance of human interaction with infocommunications in general and augmented/virtual environments in particular, it is becoming increasingly important to provide users with a “virtual physics” capable of emulating the richness and subtle informativeness of multimodal feedback in the physical world. In this paper, we describe an extension to an existing immersive virtual sketching...
In our paper we would like to present a three-dimensional model of a virtual library created by exploiting the capabilities of the Virtual Collaboration Arena (VIRCA) system. Based on the classification system elaborated by Callimachus we focus on the field of Greek poetry and drama in the 3rd century BC, and select some illustrious ancient authors and texts for the content of a virtual library. In...
