The method utilizes a dance motion dataset containing the motion of both dancers (leader and partner). A hidden Markov model (HMM) was used to learn the structure of the dance motions. The HMM was trained on the motion of a chosen dancer (leader or partner), and during runtime, the system predicts the progress of the chosen dance motion, which corresponds to the progress of the user's motion. The regular structure of the HMM was extended by utilizing a jump state transition, allowing the user to improvise dance motions during the runtime. Since the jump state addition increases the model's complexity, an effort was made to optimize the prediction process to ensure runtime efficiency. A few corrective steps were also implemented to ensure the partner character's motions appear natural. A user study was conducted to understand the naturalness of the synthesized motion as well as the control that the user has on the partner character's synthesized motion.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122980457","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 has been shown that the scale of the external environment is perceived relative to the size of one's body. However, the influence of avatar realism on the perceived scale has not been investigated, despite the fact that it is common to embody avatars of various representations, from iconic to realistic. This study examined how avatar realism would affect perceived graspable object sizes as the size of the avatar hand changes. In the experiment, we manipulated the realism (high, medium, and low) and size (veridical and enlarged) of the avatar hand, and measured the perceived size of a cube. The results showed that the size of the cube was perceived to be smaller when the avatar hand was enlarged for all degrees of realism of the hand. However, the enlargement of the avatar hand had a greater influence on the perceived cube size for the highly realistic avatar than for the medium-level and low-level realism conditions. This study shed new light on the importance of the avatar representation in a three-dimensional user interface field, in how it can affect the manner in which we perceive the scale of a virtual environment.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125576284","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}

As both the HMDs and the glasses require to be tightly attached to faces, wearing them together is very inconvenient and uncomfortable, and thus degrades user experiences heavily. In this paper, we propose a real-time image pre-correction technique to correct the aberrations purely by software. Users can take off their own glasses and enjoy the virtual reality (VR) experience through an ordinary HMD freely and comfortably. Furthermore, as our technique is not related to hardware, it is compatible with all the current commercial HMDs. Our technique is based on the observation that the refractive errors majorly cause the ideal retinal image to be convolved by certain kernels. So we pre-correct the image on the display according to the specific aberrations of a user, aiming to maximize the similarity between the convolved retinal image and the ideal image. To achieve real-time performance, we modify the energy function to have linear solutions and implement the optimization fully on GPU. The experiments and the user study indicate that without any changes on hardware, we generate better viewing experience of HMDs for users with optical aberrations.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120857633","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 take advantage of the commercial availability of these devices to provide a novel virtual reality-based driving training approach designed to help individuals improve their driving habits in common scenarios. Our approach first identifies improper driving habits of a user when he drives in a virtual city. Then it synthesizes a pertinent training program to help improve the users driving skills based on the discovered improper habits of the user. To apply our approach, a user first goes through a pre-evaluation test from which his driving habits are analyzed. The analysis results are used to drive optimization for synthesizing a training program. This training program is a personalized route which includes different traffic events. When the user drives along this route via a driving controller and an eye-tracking virtual reality headset, the traffic events he encounters will help him to improve his driving habits. To validate the effectiveness of our approach, we conducted a user study to compare our virtual reality-based driving training with other training methods. The user study results show that the participants trained by our approach perform better on average than those trained by other methods in terms of evaluation score and response time and their improvement is more persistent.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130902853","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}
