In this paper, we propose a pseudo-gustatory display based on the cross-modal interactions that underlie the perception of flavor. Although several studies on visual, auditory, haptic, and olfactory displays have been conducted, gustatory displays have seldom been studied. This scarcity has been attributed to the fact that synthesizing arbitrary taste from basic tastants is difficult. On the other...
In this research study, we propose a divided planar-object detection method for augmented reality(AR) applications. The proposed system prepares a database of the target object's natural features, and applies progressive sample consensus (PROSAC), which is a robust estimation method, for iterative homography calculation to achieve the multiple planar-object detection. Moreover, the proposed method...
In our research demonstration, we show a "MetaCookie+" that enables the user to experience various tastes without changing the chemical composition of foods by using the influence between modalities. It is a pseudo-gustatory display by combining the Edible Marker system which can detect the state [number/shape/6-DOF coordinate] of each piece of bitten or divided food in real time, and the...
We produced an exhibition “Digital Public Art in HANEDA AIRPORT `AIR HARBOR' - Technology Meets Air: A Sensation of a New World” in October, 2009 at the Haneda Airport which is public space and is the biggest airport in Japan. This exhibition aims to show the new concept “Digital Public Art” which tries to evolve media art to public art. This exhibition is also an experiment to bring information technology...
In this research, we introduce digital technology to museum environment by providing spherical image contents. This research built two systems. First, we introduce binocular-type system providing visitors with information about exhibits such as historical backgrounds and surrounding environment when used, and then projection device that creates full-image space by scanning. According to evaluation...
In our research, we aim to construct the Digital Display Case system which we can introduce into exhibition rooms in museums like conventional display cases, to tell visitors the background information about the exhibit more effectively. We categorize the background information into diachronicity and synchronicity, and decide specifications of the system to convey these information. Then we construct...
In this research, we evaluate pseudo-haptic, olfactory, gustatory stimulation with visual feedback to construct multi-modal display system. To evaluate pseudo-haptics, we introduce EMG and show relationship between visual feedback and subjective evaluation. To evaluate pseudo-olfaction, we construct two olfactory display systems with visual feedback and demonstrate olfactory illusion. To evaluate...
An approach to realize manipulation of elastic object in virtual environment is discussed. In the approach, the behavior of elastic object during interaction is separately described by two components: rigid-body motion and elastic deformation. The component of motion is simulated by solving equations of motion, while the component of deformation is reproduced from a set of deformation sequences in...
In this paper, the technology of non-invasive brain-computer interfacing (BCI) in immersing virtual environment was focused for navigation with no subject training. The common spatial patterns were for the first time applied to EEG-based BCI system in CAVE with five-screen configuration. The interfacing system was based on two brain states of left and right hand phantom movements. It was suggested...
We present a novel approach for constructing a virtual 3D world from a sparse set of 2D photograph images. In our approach, we do not construct a large 3D world directly from the images, instead we construct several 3D models from the images and inter-connect them. Each 3D model is photograph-based 3D model that constitutes a few faces and a high-resolution photographic texture image. By arranging...
Three-dimensional user interfaces (3D UIs) let users interact with virtual objects, environments, or information using direct 3D input in the physical and/or virtual space. In this article, the founders and organizers of the IEEE Symposium on 3D User Interfaces reflect on the state of the art in several key aspects of 3D UIs and speculate on future research.
Major challenges must be tackled for brain-computer interfaces to mature into an established communications medium for VR applications, which will range from basic neuroscience studies to developing optimal peripherals and mental gamepads and more efficient brain-signal processing techniques.
In our previous paper, we proposed an augmented reality display based on the pepper's ghost configuration that was able to display two-dimensional images on different image plane at different physical depths. In this paper, we propose the next generation of the display. Our latest display is able to display images at different physical depths simultaneously, thus it is able to display virtual objects...
Pepper's ghost is a well known technique in theater productions that allows the appearance of a semi- transparent and perhaps flying ghost on the stage. This technique has also been used with digital display to create a mixed reality (MR) system, where dynamic virtual objects are presented together with the static diorama. The usual pepper's ghost setup does not allow the presentation of the virtual...
This paper describes a wearable electronic mnemonics, the iFlashBack system that promotes human memorization process for the action the user performed in the real-world. The goal of the system is to exploit unlimited capacity of the human brain for storing the variety of information, by assisting memorization using recorded video and related information captured during interaction process to real-world...
Immersive projection displays such as CABIN and COSMOS have been connected through a broadband network. This kind of network environment is expected to be used as a multimedia virtual laboratory. In particular, video avatar technology has been developed in order to realize high-presence communication in this multimedia virtual laboratory. A video avatar is a computer-synthesized 3D image created using...
Describes the design and implementation of an artificial force display for immersive projection displays (IPD) such as CAVE or CABIN. In order to give the user maximum freedom of motion in the large virtual space generated by an IPD, it is necessary to use a portable force display that is self-contained on the user's body. Therefore, we developed a wearable force display called HapticGEAR. It is a...
In this paper we discuss application possibilities of virtual reality technology such as immersive projection technology to the field of genome science. The prototype of the visualization environment is implemented and used in analysis to elucidate the important genes in categorizing liver cancer.
A worldwide photorealistic environment includes huge amounts of datasets of different types and scales. It is almost impossible to describe such an environment using a single methodology. To manage different types and scales of these datasets, we build and handle virtual subenvironments of different types and scales separately. In addition, we propose an image-based combination method to switch between...
A new methodology to generate image-based wide-range virtual spaces is introduced. The basic principle is to display appropriate images accompanied by user's interaction, using position data. For this methodology, a huge image database indexed by position data must be sampled from the real world. A prototype of a vehicle-mounted image capturing system is developed for this purpose. The relationship...
