Presently, however, in telexistence, the key factors for matching the embodiment of the operator with the robot are unclear and lack established evaluation methods. In this paper, we experiment with out-of-body sensations in a telexistence system on the basis of the rubber hand illusion. We construct a system to self-interact with and evaluate the stimulation influence of the self-attribution and self-localization of the body.","PeriodicalId":197131,"journal":{"name":"2011 IEEE International Symposium on VR Innovation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124309558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we build upon work by solving the nondimentional Navier-Stokes equations, utilize the MacCormack method to solve the advection item for lowering numerical dissipation inherent in the semi-Lagrangian scheme, and compensate the high-detailed smoke turbulence on 2D slices over modern GPUs to shorten the simulation time. Besides, an especial rendering technique called view-aligned slices rendering is also proposed, which can effectively capture the smoke details generated by our methods and greatly reduce the time cost. Moreover, our model could also correctly handle the interaction of smoke with winds and stationary objects.","PeriodicalId":197131,"journal":{"name":"2011 IEEE International Symposium on VR Innovation","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129910597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the method, a new elastic stress term, which is derived from a modified form of the Hooke's law, is included in the traditional Navier-Stokes equation to simulate the movements of the high viscosity fluids. Benefiting from the Lagrangian nature of Smoothed Particle Hydrodynamics method, large flow deformation can be well handled easily and naturally. In addition, in order to eliminate the particle deficiency problem near the boundary, ghost particles are employed to enforce the solid boundary condition. Compared with Finite Element Methods with complicated and time-consuming remeshing operations, our method is much more straightforward to implement. Moreover, our method doesn't need to store and compare to an initial rest state. The experimental results show that the proposed method is effective and efficient to handle the movements of highly viscous flows, and a large variety of different kinds of fluid behaviors can be well simulated by adjusting just one parameter.","PeriodicalId":197131,"journal":{"name":"2011 IEEE International Symposium on VR Innovation","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129394509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When viewers view the screen through a half mirror, they see, without the aid of glasses, a 3D image superimposed in real space. RePro3D has a sensor function that recognizes user input; therefore, it can support some interactive features such as manipulation of 3D objects. In addition, a wearable haptic device, which is a part of our system, provides the user with a sensation of having touched the 3D image. In this paper, we describe the optical system of the high-density projector array used in RePro3D. Then, we describe the development of a prototype of RePro3D. The prototype is used to demonstrate that our system displays full-parallax images superimposed in real space from 42 different viewpoints.

An important step in neural decoding research is to collect the subject's motion and neural activities synchronously, which requires a real-time motion capture system with high accuracy. In this paper, we propose a practical motion capture framework with the capability of processing motion data and output character animation in real-time. We use a two-stage coarse-to-fine method to preprocess the raw motion capture data. We employ Kalman filter to coarsely estimate the positions of missing markers and filter out the possible noisy markers. The positions of the missing markers are refined with the relationship between the current frame and similar frames in motion templates. We operate the motion data in PCA space to reduce computational complexity. We present the results for our approach as applied to capturing human hand motions, which demonstrates the accuracy and usefulness of our real-time motion capture framework.","PeriodicalId":197131,"journal":{"name":"2011 IEEE International Symposium on VR Innovation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130859892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The VNM employs devised treadmills for immersive virtual running in local network or on Internet, which are embedded with various sensors for collecting the body performance data and connected with computers or Set-Top Box (STB) to synchronously control the player's avatar in the virtual game environment. VNM is implemented on a novel ISCAL model (Immersion, Scientificalness, Competitiveness, Adaptability and Learning) model for exergames design, The exercise time and intensity strictly conform to the physical exercise guidelines of the ACSM (American College of Sports Medicine), and a novel demonstration-based non-player modeling technique is employed to simulate the marathon race crowd. The VNM also allows players to learn the Chinese culture and the Olympic knowledge in the tour mode during or after the running exercise.
