The proposed system produces very low dimensional feature vectors for processing as compared to its competitors that process video data acquired from a digital camera. Consequently, the computational requirements of the proposed system are low. Furthermore, the apparatus is lightweight and can be directly worn. A prototype system is developed in our laboratories and tested to observe its capabilities. Preliminary results show that the approach provides a promising human-computer interface system with plausible accuracy.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"25 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":"125195054","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}

CMS has predominantly focused on managing documents, and on the other hand, product data management (PDM) is a digital repository of product information, including non-paper representations like CAD files. In this paper, a Web based PDM System is implemented and integrated with the open source CMS to cope with the tasks of the mechanical design. There are three major functions provided in this system. First of all, to provide users with a Web based product data vault system for design related files storage. Secondly, a data-sharing and collaboration system are created to enhance the pre-manufacturing planning and detailed design communication. The third function of this system allows user to setup an efficient programming environment for the engineering analysis processes.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"1938 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":"128811138","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}

If no additional haptic actuators are available then information about surface roughness will not be communicable and thus the degree of immersion will suffer. To compensate for this shortcome the usage of pseudo haptic feedback (Control/ Display ratio = visual cues encoding haptic object properties) is discussed and two psychophysical experiments are conducted. The first experiment deals with the perceptual scaling of different Control/ Display ratios while the second experiment examines the way, how human subjects assign suitable Control/ Display ratios to different real surfaces. It turns out that human operators can reliably perceive differences in Control/ Display ratios and a psychophysic function is established. The allocation of specific Control/ Display values to real materials does not give any generalizable results; only a global trend is observable.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"58 6 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":"123007393","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 focus on metrics used in our system. We discuss how multiple sources of information are fused and visualized featuring the capture and visualization of corresponding uncertainty metrics. We also discuss metrics related to the communication module of our disaster recovery tool. The distributed infrastructure of our system will help to support much needed planning as well as provide a response and command tool for disaster events. The goal is to provide an infrastructure that responds predictably to scale, allows data propagation without disruption or delay, and maintains records of the current situation for report generation and at the same time adheres to guidelines mandated by pre-established structures of command. We have implemented two versions of the communications module of our infrastructure, a mobile agent implementation and a subscription based implementation. Performance metrics will be shown for comparison.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"1 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":"133854577","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}

Randomly distributed sensor nodes(motes) in environment gather spatio-temporal information about target(s) and send them to a sink node for further processing. Motes like personal computers use low cost crystal based clocks. In order to maintain synchronization accuracy to acceptable levels, we shall need to synchronize them quite often. Time synchronization tries to control the time accuracy in WSN but it still has a specific limited accuracy. Motes partly process their sensed data using local fusion before sending them to the sink. Target tracking has two major error sources, first of all is that the equation system most of times gives two different answers which target can be placed in one of them. Second factor is that low time accuracy causes the great amounts of errors in results. Choosing proper fusion methods and sensing coverage degree helps us to increase the accuracy of target tracking results.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"257 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":"116067023","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}

Easy eye-gaze calibration using a moving visual target in the head-free remote eye-gaze detection system 在无头远程眼注视检测系统中使用移动视觉目标进行眼注视校准

Ebisawa","doi":"10.1109/VECIMS.2008.4592770","DOIUrl":"https://doi.org/10.1109/VECIMS.2008.4592770","url":null,"abstract":"The development of precise head-free remote eye-gaze detection devices with easy calibration is desired for human interface and human monitoring. In the system that we developed, the 3D position of a pupil is measured using stereo wide view cameras. Next, a narrow view camera unit detecting the center of the pupil and the corneal reflection of the light source is aimed at the subject eye pupil using a pan-tilt drive. Previously, we proposed an eye-gaze detection theory in which a subject must look into the center of the aperture of a narrow view camera and at a small marker on a PC screen (two-point calibration). In our past experiments conducted with such calibration at the position of approx. 70 cm from a PC screen, the subjects shifted head positions approx. 15 cm in depth and 12 cm to lateral. The results of our experiments have already confirmed the usefulness of our two-point calibration theory and the developed system. However, unlike looking at the marker on the PC screen, it was difficult during our experiments for the subjects to look at the center of the camera at the center of the aperture because the position was unclear and it was difficult to provide the timing for the subject to look at it. In this paper, we propose a calibration method by looking at just two known points other than the camera. Furthermore, we propose a calibration method using a moving visual target on the PC screen. The experimental results show that the eye gaze precision is improved by using the moving target, rather than by using the two points on the screen or by using the previous calibration method; and, the time necessary for calibration is not different.","PeriodicalId":284224,"journal":{"name":"2008 IEEE Conference on Virtual Environments, Human-Computer Interfaces and Measurement Systems","volume":"23 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":"126647205","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}
