This paper proposes a solution to this problem using a coordinated, tablet- and HMD-based, hybrid virtual environment system. Wearing a non-occlusive HMD, the user is able to view and interact with a tablet mounted on the non-dominant forearm, which provides a multi-touch interaction surface, as well as an exocentric God view of the virtual world. To reduce transition gaps across 3D interaction tasks and interfaces, four coordination mechanisms are proposed, two of which were implemented, and one was evaluated in a user study featuring complex level-editing tasks. Based on subjective ratings, task performance, interview feedback, and video analysis, we found that having multiple Interaction Contexts (ICs) with complementary benefits can lead to good performance and user experience, despite the complexity of learning and using the hybrid system. The results also suggest keeping 3DUI tasks synchronized across the ICs, as this can help users understand their relationships, smoothen within- and between-task IC transitions, and inspire more creative use of different interfaces.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124035263","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}

Although presenters usually use a pointer rod or a laser pointer, they are not convenient or easily visible on a large screen. A camera and another screen are also needed to show gestures. In this paper we propose using intuitive interface presentation support software. A presenter is superimposed onto a screen, and the person can draw there interactively. Realizing presenter movement on screen by recognizing natural and small actions, the person can move within a limited stage space. Presenters can point to any important areas and draw supplementary items with their own hand through our software, and of course show gestures on a large screen. It is expected that audiences will be better able to understand and focus.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115897629","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 often requires visualizing individual 2D slices from 3D volumetric datasets and switching between both representations. Combining an overview with a detailed view of the data [1] enables to keep the user in context when looking in detail at a slice. Given both their mobility and their adequacy to support direct manipulation, tablets are attractive devices to ease imaging analysis tasks. They have been successfully combined with tabletops [3], allowing new ways to explore volumetric data. However, while touch allows for a more direct manipulation, it suffers from the well-known fat fnger problem which can interfere with the display, making it hard to understand subtle visual changes. To overcome this problem, we propose to explore the space around tablet devices. Such approach has been used for displays [2] to separate several workspaces of the desktop. Here, we use such space to invoke commands that are not required to be performed on the tablet, thus maximizing the visualization space during manipulations.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116460424","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}

Although several studies have measured how large gains must be for people to recognize them, little is known about how quickly the gains can be changed without people noticing. We conducted an experiment where participants were asked to walk on a straight path while wearing an HMD while we dynamically increased or decreased their virtual world translation speed. Participants indicated if their speed increased or decreased during their walk. In general, we found that the starting gain affected the detection and that, in most cases, there was little difference between gradual and instantaneous gain changes. The results of this work can help inform redirected walking implementations and other HMD applications where translational gains are not constant.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131915566","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}
