First, we introduce the rubber-like exaggeration method that allows a virtual character to stretch and bend its limbs flexibly by subdividing the joint hierarchy. Second, a slow-in and slow-out filter is introduced, which is based on the time-shift filter and is useful to give a slow-in and slow-out effect to a character. Finally, we briefly introduce the optimization-based method that exaggerates the motion both spatially and temporally in order to give a good squash-and-stretch effect.","PeriodicalId":339967,"journal":{"name":"2011 International Symposium on Ubiquitous Virtual Reality","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123236262","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}

Specifically, we propose 1) a method that exploits a 2D touch screen, a 3DOF accelerometer, and compass sensors information to manipulate 3D objects in 3D space, 2) design transfer functions to map the control space of mobile phones to an augmented reality (AR) display space, and 3) confirm the feasibility of the transfer functions by implementation. Our work could be applicable to the design and implementation of a future mobile phone-based 3D user interface for AR application in normal indoor and outdoor environments without any special tracking installations.","PeriodicalId":339967,"journal":{"name":"2011 International Symposium on Ubiquitous Virtual Reality","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126693934","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 show with experiments that, if physics simulation is naively employed in AR applications, visual artifacts diminishing the realism of a scene may occur when real and virtual objects collide. This is due to the intrinsic limitation of AR in that virtual objects cannot apply forces to the real objects. We discuss possible methods to alleviate this artifacts.","PeriodicalId":339967,"journal":{"name":"2011 International Symposium on Ubiquitous Virtual Reality","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127250073","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}

Sulaiman","doi":"10.1109/ISUVR.2011.16","DOIUrl":"https://doi.org/10.1109/ISUVR.2011.16","url":null,"abstract":"Soft tissue simulation is very important in medical simulation and learning procedures. But such simulations require intensive computation. With the force feedback devices, the computation required should be much faster as touch sensation is approximately 20 times faster than that of visual. In this paper an efficient Vertex based algorithm for visual deformation is presented. Visual deformation of linear, isotropic and homogenous triangular mesh soft model is achieved by modifying a slope intercept equation of a line which is used to get a new position for the point contacted through a tip of a force feedback device. Haptic sensation is achieved using Hooke's law which is coupled with visual deformation based on our proposed algorithm. In our simulation we use up to 20K of triangles for object representation.","PeriodicalId":339967,"journal":{"name":"2011 International Symposium on Ubiquitous Virtual Reality","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128600175","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}
