Current electronic commerce offerings to the end customer have become a globally accessible mainstream purchasing pattern through the Internet technologies. E-commerce customer interaction through the web offering is largely preferred over the traditional brick and mortar purchasing interactions. With the advancement of rich content and multi modal user interaction support through web, the online...
As building structure is more and more complex, confronting evacuation prone to retrograde and blockage phenomenon, traditional plain of evacuation schematic has been difficult to meet the demand guidance for fire evacuation. In this paper, we propose a building information model (BIM) for the guidance of the three-dimensional building within the evacuation path. Full integration of BIM Technology...
Vision-based grasping for humanoid robots is a challenging problem due to a multitude of factors. First, humanoid robots use an “eye-to-hand” kinematics configuration that, on the contrary to the more common “eye-in-hand” configuration, demands a precise estimate of the position of the robot's hand. Second, humanoid robots have a long kinematic chain from the eyes to the hands, prone to accumulate...
The interactive post-production 3D video technology is a real video image visualization technology. By integrating 3D models into real videos with a very high degree of realism which matches the perspective from the moving camera, and also retaining the original quality of the video, allowing an instant interactive integration method with both real and virtual objects. This technology can also be...
Understanding visual attention has always been a topic of great interest in the graphics, image/video processing, robotics and human-computer interaction communities. By understanding salient image regions, the compression, transmission and rendering algorithms can be optimized. This is particularly important in omnidirectional images (ODIs) viewed with a head-mounted display (HMD), where only a fraction...
Wireless visual sensor networks comprise a large number of camera-equipped sensor devices and obtain visual information from field of interest. In a Wireless visual sensor network, there exist visual correlation characteristics among images observed by cameras with overlapped field of views. To describe those characteristics, the conventional method is based on image processing. However, it is too...
We introduce the concept of “spatio-data coordination” (SD coordination) which defines the mapping of user actions in physical space into the space of data in a visualisation. SD coordination is intended to lower the user's cognitive load when exploring complex multi-dimensional data such as biomedical data, multiple data attributes vs time in a space-time-cube visualisation, or three-dimensional...
Earlier we have presented an outline of the architecture of Preksha — a Hindi text visualizer — system for visualizing Hindi text. Preksha is an automatic text visulizer (ATV) for free-word order Hindi language. It consists of a computational process of understanding natural language, and scene generation by appropriate placement of objects in visual output using spatial relations. This paper discusses...
The main objective of this research is to give a cognitive support to a person for understanding Hindi language text using automatic text visualization (ATV). ATV is especially useful for the persons with learning disabilities (LD). This paper focuses on the background and complexity of the problem. The impact on comprehension through visualized text over reading the text is discussed. The architecture...
In order to promote the integration of information technology and professional curriculum, optimize the teaching process and effect of higher vocational curriculum, and improve the ability of teachers to use modern information technology. At the same time, the modern vocational education advocates “work and study, the integration of theory and practice, do in Teaching, learning by doing.” Numerical...
This paper introduces a method to identify the focused object in eye images captured from a single camera in order to enable intuitive eye-based interactions using wearable devices. Indeed, eye images allow to not only obtain natural user responses from eye movements, but also the scene reflected on the cornea without the need for additional sensors such as a frontal camera, thus making it more socially...
New challenges and demands on software engineering education are presented by rapid changes and increased complexity of software systems. This paper presents the VisAr3D environment that has been developed as an innovative proposal to be introduced in the classroom to provide a 3D visualization of UML models. The user is invited to intuitively understand the model elements in this 3D environment....
Representative distribution of body shapes is needed when simulating crowds in real-world situations, e.g., for city or event planning. Visual realism and plausibility are often also required for visualization purposes, while these are the top criteria for crowds in entertainment applications such as games and movie production. Therefore, achieving representative and visually plausible body-shape...
Great progress has been made in computer vision-based localization systems. However, some systems tend to work well only in certain visually feature-rich environments. It is often the case that feature-based matching techniques can have a hard time dealing with scenes with only a few features or a large number of repetitive features. In these situations, computer vision-based localization may fail...
It is increasingly common to embed embodied, human-like, virtual agents into immersive virtual environments for either of the two use cases: (1) populating architectural scenes as anonymous members of a crowd and (2) meeting or supporting users as individual, intelligent and conversational agents. However, the new trend towards intelligent cyber physical systems inherently combines both use cases...
Many biologists check and analyze the result of alignment directly for various purpose. The more we get the genome data easily, the more alignment result that needed to be analyzed increase. The new proposed visualization model for alignment sequence is designed to reveal the base sequence of alignment result, which is 3d random walk plot model, developed as Web-GL based Web system. Using this model,...
This demo presents a fully immersive and interactive virtual environment (VE) — the ArcheoVR, which represents Itapeva Rocky Shelter, a prehistoric archeological site in Brazil. W workflow started with a real world data capture — laser scanners, drones and photogrammetry. Captured information was transformed into a carefully designed realistic 3D scene and interactive features that allows users to...
Currently healthcare practitioners use standardized patients, physical mannequins, and virtual patients as surrogates for real patients to provide a safe learning environment for students. Each of these simulators has different limitation that could be mitigated with various degrees of fidelity to represent medical cues. As we are exploring different ways to simulate a human patient and their effects...
In this paper we present an immersive virtual reality user study aimed at investigating how customers perceive and if they would purchase non-standard (i.e. misshaped) fruits and vegetables (FaVs) in supermarkets and hypermarkets. Indeed, food waste is a major issue for the retail sector and a recent trend is to reduce it by selling non-standard goods. An important question for retailers relates to...
We present Anatomy Builder VR that examines how a virtual reality (VR) system can support embodied learning in anatomy education. The backbone of the project is to pursue an alternative constructivist pedagogical model for learning canine anatomy. The main focus of the study was to identify and assemble bones in the live-animal orientation, using real thoracic limb bones in a bone box and digital...
