With these displays, users do not require any special glasses to view 3-D images, so they save users trouble and show 3-D images in a natural situation. We have been researching about an autostereoscopic display, which displays objects in 3-D as if they exist in the real world. We designed our display, which is based on integral photography (IP) (Lippman, 1908), to make autostereoscopic images more realistic. We extended the IP concept to display not only still images but also videos. We named our concept integral videography (IV) (Liao et al., 2002). To demonstrate a possible application of this concept, we developed a character interaction system consisting of a range sensor (for 3-D input) and an IV display (for 3-D output). In this system, any virtual 3-D object on the screen moves around and responds to user input interactively. User input should not involve pushing buttons but be achieved through natural body movement because the virtual 3-D object \"exists\" in the real world. So we use the ultrasonic range sensors to sense the body movements. We adopt a Tamagotchi character as 3-D moving object, which moves around in a 3-D park. When a user extends a hand toward it, it notices and moves to the front of the park to greet him or her.","PeriodicalId":301785,"journal":{"name":"2007 IEEE Symposium on 3D User Interfaces","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133528086","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}

However, within these explorations we continue to rely on Brunelleschi's perspective for display and map the interactive control space directly into it without much thought on the effect that this default mapping has. In contrast, there are many possibilities for creating 3D interaction spaces, thus making it important to run user studies to examine these possibilities. Options in mapping the control space to the display space for 3D interaction have previously focused on the manipulation of control-display ratio or gain. In this paper, we present a conceptual framework that provides a more general control-display description that includes mappings for flip, rotation, skew, as well as scale (gain). We conduct a user study to explore 3D selection and manipulation tasks in three of these different mappings in comparison to the commonly used mapping (perspective mapping of control space to a perspective display). Our results show interesting differences between interactions and user preferences in these mappings and indicate that all may be considered viable alternatives. Together this framework and study open the door to further exploration of 3D interaction variations","PeriodicalId":301785,"journal":{"name":"2007 IEEE Symposium on 3D User Interfaces","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114324012","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}

Many C-VEs replicate the VE on each user's machine to allow for real-time interactions. However, this solution does not work well when modifying voxel-based C-VEs because large and frequent volumetric updates make it difficult to synchronize the C-VE. This paper describes a hybrid depth-buffered image (DBI) and geometry-based rendering method created to simulate visual interactions between local virtual bone cutting tools and remotely maintained volumetric bone material for a craniotomy simulator. For real-time interactions, users only store a DBI of the volumetric C-VE and composite it with rendered images of surgical tools. Additionally, we describe methods to combat network bandwidth/latency to remotely simulate haptic and bone drilling interactions between users' tools and the volumetric VE. For haptic feedback, a multi-rate solution (Cavusoglu and Tendick, 2000) allows users to construct a local approximation of the volumetric C-VE to compute new forces. Only 2D DBI updates are required to synchronize different users when the bone changes due to drilling. Our approach provides an improved performance over a replicated VE that uses 3D model-based updates","PeriodicalId":301785,"journal":{"name":"2007 IEEE Symposium on 3D User Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132963797","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}
