We developed, based on the I$^2$R NeuroComm BCI platform, a novel Graphical User Interface (GUI) to allow composition of short melodies by selecting individual musical notes. The user can select any individual musical key (quarter note with Do, R'{e}, Mi, Fa, Sol, La, Si, Do, etc.), insert a silence (quarter rest), delete (Del) the last note to correct the composition, or listen (Play) to the final melody, shown in text form and as a musical partition. Our BCI system for music composition has been successfully demonstrated and shown to be, with very short training time, effective and easy to use. This work is the first step towards a more intelligent BCI system that will extend current BCI-based Virtual Reality (VR) navigation for e.g. exploring a Virtual Synthesizer Museum/shop, in which the user would first move around within the virtual museum/shop and at the point of interest would try the synthesizer by composing music. More advanced modes (e.g. musical puzzle) with various levels of difficulty will be added in future developments as well as using the Open Vibe environment and mobile platforms such as the Apple's iPAD.","PeriodicalId":410870,"journal":{"name":"2010 International Conference on Cyberworlds","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121270266","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}

Implementation of torque feedback allows the user to have more realistic experience during force simulation and find the optimum docking positions faster. In this paper, we propose a haptic rendering algorithm for biomolecular docking with torque force. It enables the user to experience six degree-of-freedom (DOF) haptic manipulation in docking process.

Over the past years, proposals have been made to model trust relations computationally, either to assist users or for modeling purposes in multi-agent systems. These models rely implicitly on the social networks established by participating entities (be they autonomous agents or internet users). However, state-of-the-art trust frameworks often neglect the structure of those complex networks. In this paper, we present a new approach allowing agent-based trust frameworks to leverage information from so-called weak ties that would otherwise be neglected. An effective and robust voting scheme based on an agreement metric is presented and its benefit is shown through simulations.","PeriodicalId":410870,"journal":{"name":"2010 International Conference on Cyberworlds","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133172314","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 3D lower limb bone models reconstructed from CT images, a 3D feature construction system is developed to find the lower limb alignment. This paper presents new methods to automatically identify the anatomic axes, mechanical axes, joint center points, and reference planes of the lower extremities. As far as we know, there is no other system that can construct all these features automatically. With the above identified features, our system can calculate the related angles of the lower limb alignment accurately for orthopedic knee surgery planning. We applied our system on two groups of specimen (with 6 pairs of lower limbs), and the resulting related angles are identical to the actual angles of the lower limb alignment.","PeriodicalId":410870,"journal":{"name":"2010 International Conference on Cyberworlds","volume":"136 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130864987","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}

One of challenging issues in behavior modeling is how virtual agents make decisions given some time-critical and uncertain situations. In this paper, we present HumDPM, a decision process model for virtual agents, which incorporates two important factors of human decision making in time-critical situations: experience and emotion. In HumDPM, rather than relying on deliberate rational analysis, an agent makes its decisions by matching past experience cases to the current situation. We propose the detailed representation of experience case and investigate the mechanisms of situation assessment, experience matching and experience execution. To incorporate emotion into HumDPM, we introduce an emotion appraisal process in situation assessment for emotion elicitation. In HumDPM, the decision making process of an agent may be affected by its emotional states when: 1) deciding whether it is necessary to do a re-match of experience cases, 2) determining the situational context, and 3) selecting experience cases. We illustrate the effectiveness of HumDPM in crowd simulation. A case study for emergency evacuation in a subway station scenario is conducted, which shows how a varied crowd composition leads to different evacuation behaviors, due to the retrieval of different experiences and the variation of agents' emotional states.","PeriodicalId":410870,"journal":{"name":"2010 International Conference on Cyberworlds","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129345306","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}

Especially the anatomical proportion can be employed as a benchmark in model segmentation and joint extraction. Unfortunately, the anatomical proportion is usually measured with the Euclidean distance, which makes it difficult to correlate it with the surface mesh. To bridge this gap, we take advantage of the property of the geodesic metrics that is invariance to rotation, translation, scaling and model pose, and propose an original geodesic model in which the length of each part of human body is measured by geodesic metrics, by which the anatomic proportions can be directly mapped to the contours of the mesh surface of human body in arbitrary pose. Combining the geodesic model with automatic extraction of feature points, we can determine the candidate scopes of joint positions and boundaries between the parts on meshes, and then refine the joint positions in the scopes using existing methods. And finally, we illustrate the utility of the geodesic model with an application to joint extraction.","PeriodicalId":410870,"journal":{"name":"2010 International Conference on Cyberworlds","volume":"214 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113990030","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}
