Employing a novel software model, CRAM (Course Resource with Active Materials), we asked participants to learn a specific aircraft maintenance task. The evaluation sought to identify the type of familiarization training that would be most useful prior to hands on training, as well as after, as skill maintenance. We found that participants develop an increased awareness of hazards when training with stimulating technology — in particular (1) interactive, virtual simulations and (2) videos of an instructor demonstrating a task — versus simply studying (3) a set of written instructions. The results also indicate participants desire to train with these technologies over the standard written instructions. Finally, demographic data collected during the evaluation elucidates future directions for VR systems to develop a more robust and stimulating hazard training environment.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129131167","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 fidelity of the prototypes has been evaluated in comparison with the corresponding real products, when used for performing the same tests. Differently from the traditional use of Virtual Prototypes, which aims at evaluating the product design, we have used iVPs for the interaction design of a new product, i.e. it has been used as a means to define the design parameters used for the specification of a new product.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116724836","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}

To ensure that the tennis ball appears spatially accurate from the player's view point when projected onto the display walls, the positions of both eyes are obtained using head tracking. The tracker to display latency was determined to be 40 milliseconds. The pilot study with proficient players shows that they are able to accurately intersect the trajectory of the virtual ball with their racket, with an average error of less than 0.1m. This initial finding will be useful for immersive virtual reality applications involving high speed tasks.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127356082","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}

Modeling the OSTHMD and the subject's dominant eye as a pinhole camera, findings show that a correspondence point distribution well distributed along the user's line of sight yields less variant parameter estimates. The estimated eye point location is studied in particular detail. The findings of the experiment are complemented with simulated data which show that image plane orientation is sensitive to the number of correspondence points. The simulated data also illustrates some interesting properties on the numerical stability of the calibration problem as a function of alignment noise, number of correspondence points, and correspondence point distribution.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115238283","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}

In PF, the positions of the user's head and hands are projected onto the ground, and travel direction and speed are computed based on direction and magnitude of the vector from the midpoint of the projected hand positions to the projected head position. The two baseline conditions both use a single hand to control the direction, with speed controlled discretely by button pushes with the same hand in one case, and continuously by the distance between the hands in the other case. Users were asked to travel through a simple virtual world and collect virtual coins within a set time. We found no significant differences between travel conditions for reported presence or usability, but a significant increase in nausea with PF. Total travel distance was significantly higher for the baseline condition with discrete speed selection, whereas travel accuracy in terms of coin-to-distance ratio was higher with PF.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133218862","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}

In the proposed system, we use our ungrounded pen-shaped kinesthetic display as the interface. The kinesthetic display device can generate kinesthetic sensations on the user's fingers. Because our system does not use mechanical linkages, the user can freely move his/her hand and feel the sensation of touching virtual objects. In the proposed system, the user can easily and intuitively create various 3D shapes by drawing closed curves in air using the device. The created shapes are generated in a physics-based simulation environment and are displayed as 3D images. Therefore, the user can touch and see the drawn shapes as though they exist in reality.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123336308","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 proposed approach removes an object and replaces it with its purposely-modified replica. The solution uses dynamic texture techniques and Inpaint to enhance the visual response of the modification performed.
