The system has been designed to integrate and interconnect a wide range of computational neuroscience models to construct embodied interactive psychobiological models of behaviour. An example application of the framework combines models of the facial motor system, physiologically based emotional systems, and basic neural systems involved in early interactive behaviour and learning and embodies them in a virtual infant rendered with realistic computer graphics. The model reacts in real time to visual and auditory input and its own evolving internal processes as a dynamic system. The live state of the model which generates the resulting facial behaviour can be visualized through graphs and schematics or by exploring the activity mapped to the underlying neuroanatomy.","PeriodicalId":220010,"journal":{"name":"SIGGRAPH Asia 2014 Autonomous Virtual Humans and Social Robot for Telepresence","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132026549","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}

Embodied agents usually function in a dynamic, uncertain, and uncontrolled environment, and exploiting them is a chaotic and error-prone task which demands high-level behavioral controllers to be able to adapt to failure at lower levels of the system. The conditions in which space robotic systems such as spacecraft and rovers operate, inspire by necessity, the development of robust and adaptive control software. In this paper, we propose a generic architecture for migrating and autonomous agents inspired by onboard autonomy which enables the developers to tailor the agent's embodiment by defining a set of feasible actions and perceptions associated with the new body. Evaluation results suggest that the architecture supports migration by performing consistent deliberative and reactive behaviors.","PeriodicalId":220010,"journal":{"name":"SIGGRAPH Asia 2014 Autonomous Virtual Humans and Social Robot for Telepresence","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131831501","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}

By mapping the 2D positions of the dense trajectories from RGB video to the corresponding positions in the depth video, we can recover the 3D trajectory of the tracked interest points, which captures important motion information along the depth direction. To characterize the 3D trajectories, we apply motion boundary histogram (MBH) to depth direction and propose 3D trajectory shape descriptors. Our proposed 3D trajectory feature is a good complementary to dense trajectory feature extracted from RGB video only. The performance evaluation on a challenging unconstrained RGB--D activity recognition dataset, i.e., Hollywood 3D, shows that our proposed method outperforms the baseline methods (STIP-based) significantly, and achieves the state-of-the-art performance.","PeriodicalId":220010,"journal":{"name":"SIGGRAPH Asia 2014 Autonomous Virtual Humans and Social Robot for Telepresence","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117236130","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 limitation is in part due to the limited range and the relative simplicity of spectral properties of the materials simulated in a virtual environment. Our work starts with a fast classification and retrieval for handling the large numbers of multi-scale texture samples of complex deformable materials, such as, woven and knitted fabrics. We have developed a general system that can also serve as a unified platform for other material analysis and classification and a 3D panel design system for 3D clothing modeling and draping. Multi-scale color theme indexing for image acquisition and retrieval can be more intuitively supported by a multi-touch gesture interface that is now the preferred mode of interacting with tablets, screens, and other visual communication devices. These also add to the collaborative modes of input and retrieval in fabric and fashion design for virtual agents. In this paper we describe the process of texture analysis of real fabric materials and preliminary models for the 3D texture generation for virtual clothing, color theme design, and ultimately 3D draping based on robust collision detection methods.","PeriodicalId":220010,"journal":{"name":"SIGGRAPH Asia 2014 Autonomous Virtual Humans and Social Robot for Telepresence","volume":"26 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133686244","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 paper presents a novel feature representation to recognize human activities from video sequences captured by a depth camera. We assemble local neighboring hypersurface normals from a depth sequence to form the polynormal which jointly encodes local motion and shape cues. Fisher vector is employed to aggregate the low-level polynormals into the Polynormal Fisher Vector. In order to capture the global spatial layout and temporal order, we employ a spatio-temporal pyramid to subdivide a depth sequence into a set of space-time cells. Polynormal Fisher Vectors from these cells are combined as the final representation of a depth video. Experimental results demonstrate that our method achieves the state-of-the-art results on the two public benchmark datasets, i.e., MSRAction3D and MSRGesture3D.","PeriodicalId":220010,"journal":{"name":"SIGGRAPH Asia 2014 Autonomous Virtual Humans and Social Robot for Telepresence","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132977758","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}

These artificial characters should understand the users' behaviors through various sensors and respond back using multimodal output. Besides natural multimodal interaction, they should also be able to communicate with multiple users and among each other in multiparty interactions. Previous work on interactive virtual humans and social robots mainly focuses on one-to-one interactions. In this paper, we study tracking and fusion aspects of multiparty interactions. We first give a general overview of our proposed multiparty interaction system and mention how it is different from previous work. Then, we provide the details of the tracking and fusion component including speaker identification, addressee detection and a dynamic user entrance/leave mechanism based on user re-identification using a Kinect sensor. Finally, we present a case study with the system and provide a discussion on the current capabilities, limitations and future work.","PeriodicalId":220010,"journal":{"name":"SIGGRAPH Asia 2014 Autonomous Virtual Humans and Social Robot for Telepresence","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130909203","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}
