A multi-component olfactory display is developed, which enables generation of a variety of odors by blending multiple odor vapors with arbitrary ratios. In this research demo, the two contents using the olfactory display will be demonstrated. The first one is the experiment on odor approximation using odor components extracted from a mass spectrum database. The second one is the reproduction of video with smell. The temporal changes of odor kind and its concentration can be recorded and can be presented together with movie obtained from a web camera. People can enjoy the recorded video with scents.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122324201","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 indoor environment is characterized by strong linear perspective cues; we attempted to re-create these cues in the outdoor environment. In the indoor environment, we found an overall pattern of underestimation of depth that is typical for virtual environments and AR systems. However, in the outdoor environment, we found that subjects overestimated depth. In addition, our synthetic linear perspective cues met with a measure of success, leading users to reduce their estimate of the depth of distant objects. We describe the experimental procedure, analyze the data, present the results of the study, and discuss the implications for mobile, outdoor AR systems.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126769363","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}

This paper expands on recent work which allowed unidirectional touch from human to VH, by evaluating bidirectional touch as a new channel for nonverbal communication. A VH augmented with a haptic interface is able to touch her interaction partner using a pseudo-haptic touch or an active-haptic touch from a co-located mechanical arm. Within the context of a simulated doctor-patient interaction, two user studies (n = 54) investigate how touch can be used by both human and VH to communicate. Results show that human-to-VH touch is used for the same communication purposes as human-to-human touch, and that VH-to-human touch (pseudo-haptic and active-haptic) allows the VH to communicate with its human interaction partner. The enhanced nonverbal communication provided by bidirectional touch has the potential to solve difficult problems in VH research, such as disambiguating user speech, enforcing social norms, and achieving rapport with VHs.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116128006","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 we attempt to support tele-presence between people, there are two main technologies that can be used today: video-conferencing (VC) and collaborative virtual environments (CVEs). In VC, one can observe eye-gaze behaviour but practically the targets of eye-gaze are only correct if the participants remain relatively still. We attempt to support eye-gaze behaviour in an unconstrained manner by integrating eye-trackers into an Immersive CVE (ICVE) system. This paper aims to show that while both ICVE and VC allow people to discern being looked at and what else is looked at, when someone gazes into their space from another location, ICVE alone can continue to do this as people move. The conditions of aligned VC, ICVE, eye-gaze enabled ICVE and co-location are compared. The impact of factors of alignment, lighting, resolution, and perspective distortion are minimised through a set of pilot experiments, before a formal experiment records results for optimal settings. Results show that both VC and ICVE support eye-gaze in constrained situations, but only ICVE supports movement of the observer. We quantify the mis-judgements that are made and discuss how our findings might inform research into supporting eye-gaze through interpolated free viewpoint video based methods.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125104817","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}

It supports composition of lenses and the user can influence the resulting visualization by interactively changing the order in which the individual lens effects are applied.

The approach aims at simulating the real-life experience of observing an outside world through one or multiple windows. Here, the display screen serves as a virtual window such that viewers moving in front of the display can observe different part of the scene which is also moving in the opposite direction. In order to generate this see-through experience, a virtual 3D scene is first created and placed behind the display. Then, the viewers' 3D positions and motion are tracked by a 3D viewer tracking method based on multiple infra-red cameras. The virtual scene is rendered by 3D graphics engines in real-time speed, based on the tracked viewer positions. A prototype system has been implemented on a large-size tiled display and was able to bring viewers a realistic and natural 3D see-through experience.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"2011 30","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114087415","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}

Adaptive resource allocation is a key issue in NVEs, since user interactions affect system resources which in turn affect the user's experience. Such interplay between the users and the system can be modeled using Game Theory. Game Theory is an analytical tool that studies decision-making between interacting agents (players), where player decisions impact greatly other players. We propose a basic structure for a Game Theory model that describes the interaction between the users and the system in NVEs based on an exploratory study of mobile virtual environments.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"791 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114095698","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}

We propose a novel method to render in a single graphical context objects handled by separate programs based on different VR frameworks, even when the various applications are running on different machines. Our technique is based on a network rendering architecture, where both origin and destination applications communicate through a set of protocols that deliver compressed graphical instructions and keep the machines synchronized. Existing applications require minimal changes in order to be compatible with our system; in particular we tested the validity of our approach on a number of rendering frameworks (Ogre3D, OpenSceneGraph, Torque, XVR).
