It has symptoms similar to Motion Sickness, such as dizziness, nausea etc. Although there have been many cybersickness experiments conducted with persons without disabilities, persons with disabilities, such as Multiple Sclerosis (MS), have been minimally studied. This is an important area of research because cybersickness could have negative effects on virtual rehabilitation effectiveness and the accessibility of VEs. For this experiment, we recruited 16 participants - 8 persons with MS and 8 persons without MS from similar demographics (e.g. age, race). Two participants from population without MS could not complete the experiment due to severe cybersickness. We asked each participant to experience a VE. We collected Galvanic Skin response (GSR) data before and during VR exposure; GSR is commonly used as an objective measure of cybersickness. Also, Simulator Sickness Questionnaire (SSQ) feedback was recorded before and after the experiment. SSQ results show that the VE induced cybersickness in the participants. The GSR data suggests that the cybersickness may have induced similar physiological changes in participants with MS as participants without MS, albeit with greater variability in participants without MS. However, participants with MS had significantly lower GSR during VR exposure. In this paper, we compare the effects of cybersickness between the people with MS and the people without MS with respect to SSQ score and GSR data.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115924196","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 introduces the SelfEar project, aimed at low-cost acquisition and personalization of Head-Related Transfer Functions (HRTFs) on mobile devices. This first version focuses on capturing individual spectral features which characterize external ear acoustics, through a self-adjustable procedure which guides users in collecting such information: their mobile device must be held with the stretched arm and positioned at several specific elevation points; acoustic data are acquired by an audio augmented reality headset which embeds a pair of microphones at listener ear-canals. A preliminary measurement session assesses the ability of the system to capture spectral features which are crucial for elevation perception. Moreover, a virtual experiment using a computational auditory model predicts clear vertical localization cues in the measured features.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133656830","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}

Except for inappropriate horizontal and vertical disparity, one major problem is that people's binocular vergence and focal length in the cinema remain inconsistent from normal visual habits. Psychologists discovered the horopter and Panum's fusional area to describe zero-disparity points projected on the retinas based on accommodation-convergence consistency. In this paper, inspired by these concepts, we propose a stereoscopic effect correction system for perceptual enhancement according to fixated region and scene information. As a preprocessing step, tracking and stereo matching algorithms are implemented to prepare cues for further transformation in 3D space. Then in order to accomplish certain visual effects, we describe a geometric framework for disparity refinement and image warping based on parameter adjustment of the virtual stereoscopic rig. For evaluation, subjective experiments have been conducted to prove the effectiveness of our method. Therefore, our work provides a possibility to improve the audience experience from a formerly underexplored perspective.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124479469","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}
