These lenses are created seamlessly as the user focuses his gaze on an object, expanding the target object. The expanded object can then be manipulated as if the user was standing next to it. To determine its effectiveness, this interface was evaluated against three other well known interaction techniques - direct manipulation, Go-Go hand, and HOMER. Testing showed that the lens interface was superior in accuracy to the others, but it took more time to complete a given task.","PeriodicalId":131574,"journal":{"name":"2008 IEEE Symposium on 3D User Interfaces","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116054317","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}

This can be a more efficient input method than unrestricted 6-DOF manipulation, since many 3D widgets impose some restrictions on how they can be manipulated. In particular for tasks that are in essence two-dimensional, such as drawing a contour on a surface, tangible controllers have advantages over unrestricted devices. This is especially useful in 3D environments which do not offer 2D input, such as the CAVE. We have combined the tangible controller with a 3D Magic Lens style visualization technique. We have conducted a small user study, in which we compare different input methods for drawing a contour on a three-dimensional curved surface using a 3D contour widget.","PeriodicalId":131574,"journal":{"name":"2008 IEEE Symposium on 3D User Interfaces","volume":"603 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116352155","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}

Based on the results of a pilot study we have quantified to which degree users can unknowingly be redirected in order to guide them through an arbitrarily sized VE in which virtual paths differ from the paths tracked in the real working space. We further introduce the concept of dynamic passive haptics which enables a user to interact with a VE. By means of this concept any number of virtual objects can be mapped to real proxy objects having similar haptic properties, i. e., size, shape and surface structure, such that the user can sense these virtual objects by touching their real world counterparts. Thus dynamic passive haptics provides the user with the illusion of interacting with a desired virtual object by redirecting her/him to the corresponding proxy object.","PeriodicalId":131574,"journal":{"name":"2008 IEEE Symposium on 3D User Interfaces","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127081739","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 user controls the interface by hopping onto it, walking back and forth, jumping on it or leaning his body in a direction. Strain sensors are attached to the beam, and by using the sensor data, approximate position of user's center of gravity and change of the balance can be estimated. The interface was applied to an interactive system, which is a combination of a balance beam and computer graphics.","PeriodicalId":131574,"journal":{"name":"2008 IEEE Symposium on 3D User Interfaces","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124996052","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}

Through a desktop haptic probe, shaped as a baton, you are able to stir and feel the magical fluid inside a bowl. As you follow the potion recipe, you feel how the fluid changes its viscosity, density, velocity and other properties. Various hapto-visual user interfaces enable users to interact in three-dimensions with the digital world and receive realistic kinesthetic and tactile cues in a computer-generated environment. So far solid or deformable objects have been experimented for haptic-tactile feedback. In this paper we innovate by devising techniques that enable the haptical rendering of shape-less objects, such as fluids. Focusing on the real-time performance to enhance the user's experience, the system imitates the physical forces generated by the real-time fluid animation, stirring movements and fluid changes. We achieved real-time 3D fluid and overcame the challenges that arise during the integration of both haptics and graphics workspaces, the free-view visualization of 3D fluid volume, and the rendering of haptic forces. These fluid interaction techniques with haptic feedback have wide possible applications including game development and haptic communities.","PeriodicalId":131574,"journal":{"name":"2008 IEEE Symposium on 3D User Interfaces","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129451581","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}
