AR has recently attracted attention again due to the rapid advances in related multimedia technologies as well as various glass-type AR display devices. However, in order to widely adopt AR in alternated realities, it is necessary to improve various core technologies and integrate them into an AR platform. Especially, there are several remaining technical challenges such as 1) real-time recognition and tracking of multiple objects while generating an environment map, 2) organic user interface with awareness of user's implicit needs, intentions or emotion as well as explicit requests, 3) immersive multimodal content augmentation and just-in-time information visualization, 4) multimodal interaction and collaboration during augmented telecommunication, etc. In addition, in order to encourage user engagement and enable an AR ecosystem, AR standards should be established that support creating AR content, capturing user experiences, and sharing the captured experiences.","PeriodicalId":144825,"journal":{"name":"Proceedings of the 3rd International Workshop on Multimedia Alternate Realities","volume":"370 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113997241","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 this paper, we combine the light field technology into a novel panorama viewing system implemented on Unity to provide dynamic depth of field and natural focus effect for better user experience. The system is also coped with FOVE, an HMD with eye-tracking technology, to better track the eye movements and collect the gazing parameters, e.g., gazing point, for better user experience.With such a design, a more immersive panorama image/video viewing experience is delivered. An evaluation is held for the user experience, which shows that our proposed system reduces the refocusing time by up to 319 times and increases the subjective Mean Opinion Score (MOS) by 19%.","PeriodicalId":144825,"journal":{"name":"Proceedings of the 3rd International Workshop on Multimedia Alternate Realities","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124652994","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}

Prabhakaran","doi":"10.1145/3268998.3269002","DOIUrl":"https://doi.org/10.1145/3268998.3269002","url":null,"abstract":"Unnatural, or \"magic\" navigation technique often exhibit more desirable characteristics than the natural navigation technique\" [1]. In this paper, we evaluate the effectiveness of Natural (based on real-world gesture) and Unnatural (based on an event generated from an external device) navigation techniques in offering group navigation experience in a collaborative Augmented Virtuality (AV) tour. AV is a subcategory of Mixed Reality (MR); it merges real-world objects and their actions to a virtual world. This feature of AV facilitates visual recognition of participants and their actions during a tour. In addition, by monitoring participants' actions and virtually accommodating them, a virtual group can stay spatially closer to each other during a tour; we term this as navigating-as-a-group\". As user participation can be from several sites, network impairments among the participating sites can introduce intermittent navigation. As a result, a virtual group might appear virtually spread-out and not close-knit. Therefore, selection of a simple navigation technique that offers a better navigating-as-a-group experience in the midst of network impairments is essential. In this context, (i) with the help of the Hierarchical Position Discrepancy Model (HPDM) proposed in [2], we quantify the impacts of network delay on Natural and Unnatural navigation techniques, and (ii) evaluate the user experience scores with the results of HPDM to suggest the most preferred navigation technique for a group AV tour. Results on a 3-site, 3-user group AV tour shows that \"unnatural navigation\" technique is better in providing navigating-as-a-group experience.","PeriodicalId":144825,"journal":{"name":"Proceedings of the 3rd International Workshop on Multimedia Alternate Realities","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128198154","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}

Indeed, users can simultaneously interact with virtual objects in the touch-sensitive screen and move the virtual objects with real objects (or body fingers or hands) in the elevated 2.5D space projected by the over-the-top projector in the touch-sensitive screen. Two 2D tracking devices are used to trace the real objects. Using the tracking devices, the states (position, rotation, size) of the real objects are calculated. The realistic images are then projection-mapped to the real objects using the projector installed on the top of the touch-sensitive display. We discuss three interaction mechanisms to be employed in the 2.5D interaction space: Poking, Swaying, and Rotating. A working prototype with the interaction mechanism in the 2.5D interaction space was proposed, and a large scale usability testing is being planned.","PeriodicalId":144825,"journal":{"name":"Proceedings of the 3rd International Workshop on Multimedia Alternate Realities","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132787745","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 see an opportunity for mobile video streaming to enable new task-oriented experiences such as remote shopping, virtual interactive tourism, auditing and verification, mobile crowdsourcing, and remote physical-world games. We posit that such applications may eventually lead to new employment opportunities for remote agents in developing countries. In this paper we report our experiences conducting a technology probe for one such use case: an 'escape-the-room' physical puzzle game where some of the team members remotely interacted with a video stream that was produced by other team members who were physically present in the escape room. We designed and built a mobile streaming system called Avatar which we deployed in our study with 26 participants. We report findings from our study, including observations about appropriate communication modalities for remote collaborative game playing, as well as unexpected interactions and points of friction between participants.","PeriodicalId":144825,"journal":{"name":"Proceedings of the 3rd International Workshop on Multimedia Alternate Realities","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124127531","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}
