It is now accepted that the Quality of Service (QoS) needed to support haptic feedback in networks will be significantly different from that used to support conventional real-time traffic such as voice or video, primarily because this traffic originates from a different human sense and has specific tolerances to delay and loss of the force and position that is reflected back to the user. Haptic applications therefore require a stringent QoS from the network for successful interaction in Distributed Virtual Environments (DVEs). Network impairments such as time delay, jitter and packet loss each have different (and severe) impacts on the user’s haptic experience for haptic interaction. Network delay reduces the fidelity when touching a virtual object due to reduction of force response. Jitter and packet loss can cause abrupt force feedback. All of these can cause system instability in the haptic feedback loop between the user and the virtual environment being rendered. This paper describes some of the issues and challenges that are presented whenever remote haptic interactions with virtual environments are considered, and identifies a number of QoS parameters and techniques to compensate for the network impairments in the network and in the end applications, that can be used to improve performance of such systems.","PeriodicalId":180375,"journal":{"name":"2010 Sixth International Conference on Intelligent Environments","volume":"59 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121452959","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 usability of mobile services becomes degraded while moving, since a user cannot pay enough attention to the service in a multi-task environment. Thus, it is important for mobile services to convey information to a user with less cognitive workload. In this paper, we address design issues to enhance the mobility of mobile services, and evaluate the workload caused from cognitive processes in a multi-task environment. Taking cross-modal and cross-device interactions into consideration, three factors are focused as variable parameters in the experiment: device type, contents format and information volume. Based on the experimental results, we discuss how these factors affect a cognitive process in a mobile interaction. Future work is also implicated in order to apply the findings to actual mobile user interface design.","PeriodicalId":180375,"journal":{"name":"2010 Sixth International Conference on Intelligent Environments","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127662998","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}

In order to behave properly, such systems rely on valid and reliable context information. Therefore concepts for validating the correctness of context data are required. In our previous research we have introduced the Context Pattern Method (CPM) that calculates the probability of correctness measure, which quantifies the belief that the context information is correct and reliable. In this paper we use the CPM method and two well known statistical classification methods, Linear Discriminant Analysis (LDA) and the Support Vector Machines (SVM), to validate the context information and compare their performances under different conditions.","PeriodicalId":180375,"journal":{"name":"2010 Sixth International Conference on Intelligent Environments","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121139858","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 increasing demand of collating our physical and digital lives is putting pressure on companies to come up with innovative products. Companies have to plan far ahead into the future, despite lacking the technological infrastructure. In this paper we describe the goal of a research project that, together with Intel, is investigating tools and methodologies which would allow companies to plan into the future by building online virtual prototypes. Real users, from different domains, would use these virtual prototypes to test different aspects and attributes of these potential products to provide relevant user-experience feedback. The feedback would be recorded in an automated and intelligent manner to improve the design. Developing prototypes in such mixed reality environments would enable the involvement of end users from early on. We believe such an approach would allow for better design innovation by providing mechanisms for collaborative research and development across distributed geographical locations. This short work-in-progress-paper will describe the concepts underpinning this research direction.","PeriodicalId":180375,"journal":{"name":"2010 Sixth International Conference on Intelligent Environments","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122328416","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}

Since the advent of Web 2.0, a virtual community of produsers -- all amateur content creators -- create video that was first shared on the web, and made the jump to mainstream television. This paper documents this intelligent environment that emerged on the web and how its members, making use of available tools and their own interests and enthusiasm for creation, are producing content that defies long-held standards of newsworthiness and professional production. By defying the norms, participative audience are given a medium all their own to use. In particular, web video case studies from the Philippines are tackled here, as well as the convergence movement in the broadcast industry in the Philippines.","PeriodicalId":180375,"journal":{"name":"2010 Sixth International Conference on Intelligent Environments","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127047392","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}

Our report aligns information we acquired from 332 visitors of a complex prototype system presented at a public IT fair, an internal questionnaire where 14 members of the project SemProM reported about their vision of this concept from an application and technology point of view, and the ongoing implementation works within that project. Our observations address to a large extent research issues related to smart items in general and thus do not only provide an insight to the research development process in this particular project, but also can be exploited for design decisions in other projects in this field.","PeriodicalId":180375,"journal":{"name":"2010 Sixth International Conference on Intelligent Environments","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127508875","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}
