The engine, called EnCIMA (engine for collaborative and immersive multimedia applications), enables a quick development process of applications by providing a high level interface, which has been implemented using the C++ object-oriented programming paradigm. Important characteristics of the engine are the integration of several real time graphics techniques needed by visualization applications; access to network connection management to support collaboration; 3D sound capability; the support to various specialized interaction equipments such as 3D mice, haptic devices, 3D motion trackers, data-gloves, joypads, force feedback joysticks, and; the capacity to have rendering computation and Physics simulation assigned to GPUs and PPUs, respectively. The engine also enables the developer to choose how the scene should be rendered to, i.e. using standard display devices, stereoscopy, or even several simultaneous projection for spatially immersive displays. As part of the evaluation process, we have compared the performance of EnCIMA to a game engine and two scene graph toolkits, through the use of a testbed application.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131724592","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}

Unfortunately, image-based algorithms for granulometry analysis are difficult to tune and validate. In a typical setup, one or more cameras acquire images of a scene with a great number of objects or particles that must be measured. The distribution of the sizes/shape characteristics of the elements are the common output of such systems. The creation of supervised image database where the coordinates of all elements are known is very important and it allows for testing in a suitable manner the final size/shape distribution of particles produced by the image processing system with respect to the real distribution. Due to the great amount of objects or particles in the images, it is not often convenient, or even impossible, to individually measure each single objects in order to test the capability of the image processing system to locate and measure the elements (creation of a supervised dataset). One possible solution encompasses the creation of a synthetic image dataset where the position of each elements is known a priori. In this paper we propose a virtual environment to create and test an image-based granulometric system based on the 3D engine Blender. Results are encouraging and show the effectiveness of the proposed method.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131803328","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 interface module of our EEMS includes general electronic measurement instruments such as a waveform generator, an oscilloscope and a power supply. We integrate three man-machine interfaces into one window which works in cooperation with the touch panel. The display function and the input function are controlled by different registers in the touch panel. We also design a corresponding display interface and a corresponding input interface. For the waveform generator we provide a basic waveform output button and include sine, triangle, square and arbitrary waveforms. The arbitrary waveform allows the user to draw on the grid area of the panel by hand. The output voltage and the frequency are adjustable. The oscilloscope has a grid area to show the waveform and the frequency. The power supply has an adjustable estimate to adjust the output voltage. The external interface circuit includes a waveform generator, an oscilloscope and a power supply. The embedded system connects to the external interface circuit through the general purpose input/output port (GPIO). The power supply and the waveform generator provide an output function which outputs the digital data from the embedded system. The digital data are converted by the Digital Analog Converter (DAC) and then the analog signal is output. The oscilloscope has an input function. After the external analog signal has been converted by the Analog Digital Converter (ADC), the digital data are analyzed by the embedded system and displayed in the touch panel.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116052012","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}

As a communication device which a user could operate by eye movement, we made a prototype of a head-mounted display (HMD) with the eye-gaze detection function. In the conventional HMD with eye-gaze detection system, the size was large and the eye-gaze calibration procedure must be repeated if the user moves relative to the HMD. To reduce the size of the HMD, first, in the developed prototype, a part of the optical path for displaying and that of the path for eye-gaze detection were used together. In addition, the HMD was used for one eye. Second, to improve the eye-gaze detection function, the eye-gaze point was determined from the relative position between the pupil center and the corneal reflection of the light source which were detected by the camera. In addition, the light source for irradiating the eye and the camera for capturing the eye image were arranged in infinite virtually. Furthermore, the display screen was set in infinite ideally. However, actually, the optical system for displaying was adjusted to myopia. As a result, the eye-gaze error due to the eye displacements relative to the finder of the HMD was yielded. So we proposed an eye-gaze compensation method to compensate the eye-gaze points. Finally, the Japanese character input experiment was conducted for three healthy students. The input speed was 3.45, 2.70, and 2.15 sec per one character, respectively.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"424 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122790329","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 ability of the sensor networks to collect information accurately and reliably enables building both real-time detection and early warning systems. Environment parameter measurement and supervision received a lot of attention from both academic and industrial research communities around the world. Applications supporting decisions for rapid coordinated responses to threats such as bushfires, tsunamis, earthquakes, and other crisis situation have been devised. In this paper a combined ontology and rule-bases intelligent system build over a platform for sensor data warehousing for decision support is introduced. A combined ontology of sensor networks and sensor data for environment parameter measurement is designed and discussed. A set of rule-based systems each tailored to a domain of networked sensors are linked together through a middle-layer of rule-base systems which reason with facts classified and structured as instances of the common sensor ontology. A set of meta-rules direct the intelligent activity of the whole system and requires individual rule-based systems to reason upon specific facts. The paper will also discuss the architecture and algorithms for data mining, fusion and reasoning for specific situation in Environment monitoring and supervision. Results obtained from experiments performed on the system prototype are given at the end of this paper.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126331180","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}

Therefore design of scalable network protocols is a major concern in such large scale distributed architectures. Several approaches have been proposed to aid update exchange in MMVEs. Message localization has always been a key point in the design of such distributed network protocols. Area of interest management (AoIM) mainly deals with the issues related to the update message localization with respect to the userpsilas interest. As the number of users in the virtual environment increases, update message localization becomes more important in order to prevent the transmission of a huge bulk of unnecessary updates to uninterested users. Therefore, scalable and efficient area of interest management is a crucial point in MMVE design. This paper introduces a new zone selection and distributed regional message filtering architecture for MMVE applications. We propose Delaunay tetrahedrization as a good way of virtual world partitioning due to several promising features. Moreover we propose the partitioning to be done with respect to barriers in order to reach a better performance through the filtering the updates that need not be propagated over the barriers. We will also introduce a distributed interest management protocol based on the previous partitioning technique. Our proposed distributed message dissemination approach is capable of providing the interested users with variable updates rate according to their required level of detail.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125302497","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}
