This paper documents a pilot study evaluating a simple approach allowing users to eat real food while exploring a virtual environment (VE) through a head-mounted display (HMD). Two cameras mounted on the HMD allowed for video-based stereoscopic see-through when the user’s head orientation pointed toward the food, and the VE would appear when the user turned elsewhere. The pilot study revealed that...
According to the problem that exists in restoring of the ancient architecture, in this paper, which focuses on the virtual reality system of Gu Yuan, a technical solution based on UDK and Kinect is proposed to develop a virtual reality roam system. This system includes Kinect, server and circular-screen projector system. The application of this technical solution provides a new display method for...
Nanomanipulation is an important tool for recent developments in nanoscale production, characterization and analysis, both in material and life sciences. Its use is actually limited because of its complexity. Especially inside a scanning electron microscope, kinematic constraints, open-loop actuators and lack of natural visual access are barriers for its widespread use and require an operator specialized...
In order to avoid the repeated design of Distributed Combat Visual Simulation System Architecture, we propose a Distributed Combat Visual Simulation General Expansible Architecture (VSGEA) after having analyzed and summarized the development needs of general Distributed Combat Visual Simulation System. Through parsing information table dynamically in real time, configuring general information list...
It is difficult to get awareness of user's context from sensors such kind of video cameras, RFID-Tags, GPS, PC-monitoring and another ubiquitous devices. On the other hand, it is difficult to understanding what information is got in computers for user. We are in the network-age since 1995. We use PC, smart phone, iPad and other digital gadget which are connected to the Internet every time anywhere...
In this work we propose a tool for path generation of animated beings (devices as robots, and humans) in a virtual environment. The focus of this application is the creation and edition of this path for guided tour in virtual museum. To validate this approach we present a virtual exhibition were a virtual guide following the generated path and conduces the virtual visitors in the museum.
Nowadays, interaction represents an attractive approach for deploying new forms of entertainment and art. Towards this aim, novel technologies can make possible advanced concepts of interaction, hence supporting complicated application scenarios. In this work, an interactive audiovisual installation is presented, which aims to make the participant interact with the stars in the space. Human gesture...
We describe a novel markerless camera tracking approach and user interaction methodology for augmented reality (AR) on unprepared tabletop environments. We propose a real-time system architecture that combines two types of feature tracking. Distinctive image features of the scene are detected and tracked frame-to-frame by computing optical flow. In order to achieve real-time performance, multiple...
With the development of virtual studio technology, the application in the field of education has been emerging in China, especially for high-quality educational resource authoring. However traditional virtual studio systems have not been widely deployed. The reason is not only the large investment but also the complexity of the operation and maintenance of the system. Thus new virtual studio system...
The ambiance in virtual environments is affected by the loss of multimodal information. For many purposes, the affective qualities of a virtual environment require special attention in the modeling process. In order to construct the right ambiance it can be beneficial to engineer the affective appraisal of the virtual environment. However, a userpsilas assessment of the affective qualities of a (virtual)...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
In this paper, we propose a novel user interface framework for controlling appliances in smart spaces based on the natural look of UI on physical appliances. When a user selects a specific target appliance to control, the proposed architecture and procedures provide NVUI (NaturalView User Interface) on a userpsilas mobile device to maximize userpsilas a priori familiarity with the user interface....
In this paper, we study how to exploit the context-awareness in augmented reality (AR) applications to take advantage of the context in both the high-level and low-level processing. We propose an AR system architecture that works with a context-awareness framework. In the system, both the preliminary and the final context is provided to the process that needs the context. We provide two scenarios...
Computing technology is radically changing the manner in which we work and communicate with computers. ubiquitous virtual reality (U-VR) has been researched in order to apply the concept of virtual reality and its technology into ubiquitous computing. In this paper, we analyze past research on ubiquitous virtual reality and find future research direction.
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
