By calculating the transformation matrix from the MRI coordinates and the coordinates from the markers that is on the patient, we are able to register the acquired MRI data to the patient.

The vibration was added to the heel and toe to imitate cutaneous sensation of the sole during walking. The sound of footsteps was also provided to the participant through headphones simultaneously. In this sound presentation, we used a spatial sound of footsteps of another walker as well as own footstep sound. Another walker's sound was moved along several trajectories in a VR space. We conducted an experiment to elucidate the effect of third person's footstep sound moved differently on the walking sensation of a participant. The result showed that third person's sound enhanced not only walking sensation but also translational sensation of a sitting participant. Furthermore, the effect was the highest when third person's sound came from front to backward of the participant in a VR space.","PeriodicalId":231501,"journal":{"name":"2015 IEEE Virtual Reality (VR)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123527881","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}

Our research aims at understanding the effects of such asymmetries on the user embodiment in collaborative virtual environments (CVEs). In order to do this, we have developed a prototyping platform for cooperative interaction between two users. To change the information a user has, we are incorporating “special views”[1] for each person. Also, an easily expandable array of input devices is supported, e.g. Mouse/Keyboard, Novint Falcon, Razer Hydra, ART Flightstick, Leap Motion, etc. Those devices can provide additional information to a user, like haptic feedback, but they can also be used to restrain a user, for example by providing a device with less degrees of freedom.","PeriodicalId":231501,"journal":{"name":"2015 IEEE Virtual Reality (VR)","volume":"505 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122367127","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 jointly filter both in-view dynamic geometry and outside-view static geometry. The resulting reconstruction provides the input for efficient global illumination computation in image-space.

In particular, many techniques for locomotion in VR attempt to approximate real-world walking. However, it is not yet fully understood how the design of more realistic locomotion techniques affects user task performance. We performed an experiment to compare a semi-natural locomotion technique (based on the Virtusphere device) with a traditional, non-natural technique (based on a game controller) and a fully natural technique (real walking). We found that the Virtusphere technique was significantly slower and less accurate than both of the other techniques. Based on this result and others in the literature, we speculate that locomotion techniques with moderate interaction fidelity will often have performance inferior to both high-fidelity techniques and well-designed low-fidelity techniques. We argue that our experimental results are an effect of interaction fidelity, and perform an analysis of the fidelity of the three locomotion techniques to support this argument.","PeriodicalId":231501,"journal":{"name":"2015 IEEE Virtual Reality (VR)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129074267","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 used a Leap MotionTM device to measure the movements of the hand and fingers. Participants were asked to explore the space above the device with the palm of one hand and an auditory feedback was produced only when the palm was moving into the boundaries of the surface. In order to demonstrate that curvature direction was correctly perceived by our participants, we estimated their discrimination thresholds with a psychophysical staircase procedure. Two groups of participants were fed with two different sonification of the surface. Results showed that most of the participants were able to learn the task. The best results were obtained with an auditory feedback related to the component of the hand velocity tangential to the virtual surface. This work proposes a contribution to the introduction in virtual reality of auditory virtual objects.","PeriodicalId":231501,"journal":{"name":"2015 IEEE Virtual Reality (VR)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129662753","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}
