There are some instruments which are used to watch distant, objects or people, such as a monocle, a binocular, and a telescope. When we use these instruments, we firstly take a general view without them and adjust magnification and focus of them. These operations are complicated and occupy the user's hands. Therefore, a visual extension device that is capable of being used easily without hands is extremely useful. A system developed in the previous work recognizes the movement of the user's eyelid and operating devices by using it [Hideaki et al. 2013]. However, a camera is placed in front of the eye, and that obstructs the field of view. In addition, image recognition needs much calculation cost and it is difficult to be processed in a small computer. When human intends to move his/her muscles, bioelectrical signal (BES) leaks out on the surface of skin. The BES can be measured by small and thin electrodes attached to the surface of the skin. By using the BES, user's operational intentions can be detected promptly without obstructing the user's field of view. Moreover, using BES sensors can reduce electrical power, and contribute to downsizing systems.","PeriodicalId":417667,"journal":{"name":"ACM SIGGRAPH 2016 Posters","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125572595","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}

All other layers are pushed back to the background providing an artificial depth-of-field effect.

However, 3D printers still suffer from the relatively long production time and limited output size, which are undesirable for large-scale rapid-prototyping. Zometool, which is a popular building block system widely used for education and entertainment, is potentially suitable for providing an alternative solution to the aforementioned scenarios. However, even for 3D models of moderate complexity, novice users may still have difficulty in building visually plausible results by themselves. Therefore, the goal of this work is to develop an automatic system to assist users to realize Zometool rapid prototyping with a specified 3D shape. Compared with the previous work [Zimmer and Kobbelt 2014], our method may achieve the ease of assembly and economic usage of building units since we focus on generating the Zometool structures through a higher level of shape abstraction.","PeriodicalId":417667,"journal":{"name":"ACM SIGGRAPH 2016 Posters","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130323046","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}

Using this file format avoids going back and forth between the rendering and the compositing departments because no mask image or layering are needed anymore. The technique is demonstrated in an open source software suite, including a library to read and write the EXR/Id files and an OpenFX plug-in which generates the images in any compositing software.","PeriodicalId":417667,"journal":{"name":"ACM SIGGRAPH 2016 Posters","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116770802","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}

There are some studies on the bare hand interaction[Benko et al. 2012], however a virtual object is supposed to be a hard object or a user touches a physical object during the bare hand interaction. We focus on grasping a virtual object without using any physical object. Grasping is one of the basic movements in manipulating an object and is more difficult than simple movements like touching an object. Because of the bare hand interaction with no physical object, there is no haptic device on a user's hand and so there is no physical feedback to the user. Our challenge is to provide a user with pseudo-softness while grasping a virtual object with a bare hand. We have been developing an AR system that makes it possible for a user to grasp a virtual object with a bare hand[Suzuki et al. 2014]. Using this AR system, we propose visual stimuli that correspond with the user's hand movements, to manipulate the pseudo-softness of a virtual object. Evaluation results show that with the visual stimuli a user feels pseudo-softness while grasping a virtual object with a bare hand.","PeriodicalId":417667,"journal":{"name":"ACM SIGGRAPH 2016 Posters","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115778218","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}
