In both experiments, participants were asked to pick up a virtual cube and place it at a random location in a VE. The first experiment showed that the visual appearance of a 3D cursor could influence the participants in the way they manipulated the real interaction device. The participants changed the orientation of their hand as function of the orientation suggested visually by the shape of the 3D cursor. The second experiment showed that one visual properly of the avatar (i.e., the presence or absence of a directional cue) could influence the way participants picked up the cube in the VE. When using avatars or 3D cursors with a strong directional cue (e.g., arrows pointing to the left or right), participants generally picked up the cube by a specific side (e.g., right or left side). When using 3D cursors with no main directional cue, participants picked up the virtual cube more frequently by its front or top side. Taken together our results suggest that some visual aspects (such as directional cues) of avatars or 3D cursors chosen to display the user in the VE could partially determine his/her behaviour during manipulation tasks. Such an influence could be used to prevent wrong uses or to favour optimal uses of manipulation interfaces such as haptic devices in virtual environments","PeriodicalId":301785,"journal":{"name":"2007 IEEE Symposium on 3D User Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133303266","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}

A screen panel is manipulated by a user; the position and orientation of the screen are measured by sensors; cross-sectional image of 3D volume data with the screen plane is generated and projected on the screen panel. By supporting this interaction up to a relatively high frequency motion of the screen panel, volumetric image of the 3D data is provided to user when the screen panel is quickly moved. The integrated presentation of cross-sectional and volumetric images is thought to mutually complement drawbacks each other; the volumetric image provides holistic view on the spatial structure, while the cross-sectional image provides more precise information among the volume data. A sensing system to measure the motion of screen plane using laser displacement sensors is designed, and a method to cancel the delay time from measurement to projection by predicting the motion of the screen panel is devised. Through implementation of a prototype system, feasibility of our approach is demonstrated, and future works that are required to improve the system is discussed","PeriodicalId":301785,"journal":{"name":"2007 IEEE Symposium on 3D User Interfaces","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116508050","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 task sequence (the order of operations in a system control task) is an important aspect of the design of a system control interface (SCI), because it affects the way the user must think about accomplishing the task. Most command line interfaces are based on the action-object task sequence (e.g. \"rm foo.txt\"). Most graphical user interfaces (GUIs) are based on the object-action task sequence (e.g. click on an icon then select \"delete\" from a pop-up menu). An SCI for an IVE should be transparent and induce minimal cognitive load, but it is not clear which task sequences support this goal. We designed an experiment using an interior design application context to determine the cognitive loads induced by various task sequences in IVEs. By subtracting the expected time for a user to complete the task from the total time, we have estimated the cognitive time, dependent only on task sequence. Our experiment showed that task sequence has a significant effect on the cognitive loads induced in IVEs. The object-action sequence and similar task sequences induce smaller cognitive loads than those induced by the action-object sequence. These results can be used to create guidelines for creating 3DUIs for IVEs","PeriodicalId":301785,"journal":{"name":"2007 IEEE Symposium on 3D User Interfaces","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124222901","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 traditional solution is to require the user to travel 'indirectly', using a device that changes his viewpoint in the environment without actually requiring him to move - for example, a joystick. However, other solutions involving variations on direct walking are also possible. In this paper, we present a new metaphor for natural, augmented direct locomotion through moderately large-scale immersive virtual environments (IVEs) presented via head mounted display systems, which we call seven league boots. The key characteristic of this method is that it involves determining a user's intended direction of travel and then augmenting only the component of his or her motion that is aligned with that direction. After reviewing previously proposed methods for enabling intuitive locomotion through large IVEs, we begin by describing the technical implementation details of our novel method, discussing the various alternative options that we explored and parameters that we varied in an attempt to attain optimal performance. We then present the results of a pilot observer experiment that we conducted in an attempt to obtain objective, qualitative insight into the relative strengths and weaknesses of our new method, in comparison to the three most commonly used alternative locomotion methods: flying, via use of a wand; normal walking, with a uniform gain applied to the output of the tracker; and normal walking without gain, but with the location and orientation of the larger virtual environment periodically adjusted relative to position of the participant in the real environment. In this study we found, among other things, that for travel down a long, straight virtual hallway, participants overwhelmingly preferred the seven league boots method to the other methods, overall","PeriodicalId":301785,"journal":{"name":"2007 IEEE Symposium on 3D User Interfaces","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127620671","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}

A real walking travel technique was compared to two common virtual travel techniques. Participants explored a two-story 3D maze at their own pace and completed four post-tests requiring them to remember different aspects of the environment. Testing tasks included recall of objects from the environment, recognition of objects present and not present, sketching of maps, and placing objects on a map. We also analyzed task completion time and collision data captured during the experiment session. Participants that utilized the real walking technique were able to place more objects correctly on a map, completed the maze faster, and experienced fewer collisions with the environment. While none of the conditions outperformed each other on any other tests, our results indicate that for tasks involving the naive exploration of a complex, multi-level 3D environment, the real walking technique supports a more efficient exploration than common virtual travel techniques. While there was a consistent trend of better performance on our measures for the real walking technique, it is not clear from our data that the benefits of real walking in these types of environments always justify the cost and space trade-offs of maintaining a wide-area tracking system","PeriodicalId":301785,"journal":{"name":"2007 IEEE Symposium on 3D User Interfaces","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125192642","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}
