Specifically, we explore, from a broad perspective, how the collaboration of a group of people can increase the performance on a simple target identification task. To this end, we requested a group of people to identify the location and color of a sequence of targets appearing on the screen, and measured the time and the accuracy of the response. The individual results are compared to a collective identification result determined by simple majority voting, with random choice in case of drawn. The results are promising, as the identification becomes significantly more reliable even with this simple voting, and with a small number of people (either odd or even) involved in the decision. In addition, the paper briefly analyzes the role of brain-computer interfaces in collaborative targeting, extending the targeting task by using a BCI instead of a mechanical response.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122748726","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}

With this massive amount of information over the web from different social networks like Twitter, Facebook, Blogs, etc, there has to be an automatic tool that can determine the topics that people are talking about and what are there sentiments about these topics. The goal of the research described in this paper was to develop a prototype that can \"feel\" the pulse of the Arabic users with regards to a certain hot topic. Our experience in extracting Arabic hot topics from Twitter is presented in this paper. The unigram words that occurred more than 20 times in the whole corpus were used as features for clustering the tweets using bisecting k-mean clustering algorithm. This has resulted in purity of 0.704 and entropy of 0.275. The score generated for the quality of the generated topic was 72.5%.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127736139","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 HCI as well as UbiComp, it has inspired many projects venturing to exploit the semantics of individual users' contexts. That is lead by intentions to study the potential of human-machine collaborative interaction and make applications behave more efficiently, user-friendly and invisibly. This has not considerably turned into a new paradigm of computing, we believe, due to a not completely satisfied theoretical model of what context really is. This paper intends to alleviate that by specifying a model of context that is even more personal, and by that better adapted to the particular domain of in-car navigation. The model is next used to implement an application, which demonstrates its usefulness. Future work shall take this experiment further, to support the inner-local context-aware functionality of such systems in practice.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127801065","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 assess not only what the effects are but also what they are caused by, we carried out experiments in which naïve participants instructed the humanoid robot iCub on a set of shapes and on a stacking task in two conditions, once with socially contingent, nonverbal feedback implemented in response to different gaze and demonstrating behaviors of the human tutor, and once with non-contingent, saliency-based feedback. The results of the analysis of participants' linguistic behaviors in the two conditions show that contingency has an impact on the complexity and the pre-structuring of the task for the robot, i.e. on the participants' tutoring behaviors. Contingency thus plays a considerable role for learning by demonstration.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114026900","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}

Cliff","doi":"10.1109/CTS.2013.6567214","DOIUrl":"https://doi.org/10.1109/CTS.2013.6567214","url":null,"abstract":"In this paper we describe the design and implementation of Sensomax, a novel agent-based middleware for wireless sensor networks (WSNs), which is written in Java and runs on networks of various Java-enabled embedded systems ranging from resource-constrained Sun Spot nodes to resource-rich Raspberry Pi boards. Programming WSNs tends to be a complex task for developers, as it requires detailed knowledge of underlying hardware resources as well as their firmware or operating systems. Although many solutions have been proposed up to this date, only a few of those are capable of satisfying challenging demands such as serving multiple user applications and reprogramming the network at run-time in popular highlevel languages such as Java. Sensomax presents a novel combination of several best practices from existing solutions, facilitating fully distributed and decentralized bulk programming and/or updating of sensor nodes; serving multiple simultaneous applications deployed by single or multiple users; allowing dynamic run-time changes in the application requirements; and offering on-the-fly switching between time-driven, data-driven, and event-driven operational paradigms. Sensomax provides a sophisticated set of APIs, a feature-rich desktop application, a web application for cloud-based distributed networks, and a simulator. We demonstrate Sensomax in operation on a real network of 12 Sun Spots deployed as an environment-monitoring system, and 600 virtual Sun Spot nodes running continuously over periods of several weeks, using a novel statistically rigorous adaptive change-point detection algorithm to identify significant “anomalous” changes in the monitored data-streams.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131455704","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}

{"title":"Towards collaborative-oriented health IT systems design","authors":"Yunan Chen","doi":"10.1109/CTS.2013.6567272","DOIUrl":"https://doi.org/10.1109/CTS.2013.6567272","url":null,"abstract":"Summary form only given. As the field of healthcare accelerates into the digital age, patient care is increasingly mediated and enabled by ICT systems. With the wide adoption of large-scale information infrastructure, such as Electronic Health Records (EHR), in healthcare organizations, and the use of various patients care technologies deployed in homes and communities settings, health practitioners and consumers are able to make informed decisions based on readily available patient care information. US policy-makers have publicly touted revolutionizing future healthcare through the use of EHR systems [1], since these systems allow evidence-based practices, and foster various record-based research and administration activities. Nevertheless, prior studies have shown that these potential benefits are often compromised by the ineffective design of health IT systems [2], especially when the designs are not properly aligned with the practices of the real patient care.Despite having been originally designed as record-keeping tools, many health IT systems have now become central infrastructures hosting collaboration and communication activity - an essential part of health practices. Patient care work is highly distributed among multiple stakeholders across different locations, such as the home, community and various clinics, over different periods of time [3]. These stakeholders, on one hand, jointly document and use patient care information; and, on the other, constantly articulate and communicate patient-specific information in achieving collaborative work. However, as previous research has shown, a lack of understanding and consideration of what constitutes effective collaborative work across temporal-spatial boundaries often lead to inefficiencies, communication breakdowns, and even medical errors in using health IT systems [e.g. 4, 5]. This talk attempts to address one central research question - how can EHR systems be designed to support collaborative work practices? Drawn on insights obtained from my recent field studies on the adoption, adaptation and appropriation of EHR, PHR and other patient care systems in a variety of clinical and home settings, I will describe the challenges and opportunities identified in designing medical records systems that are aligned with collaborative-nature of work practices [5, 6, 7, 8]. In particular, this talk aims to address the following questions: a) How can health IT systems be designed to mediate work practices conducted by heterogeneous stakeholders at different temporal-spatial points of care?; b) How can informational awareness be provided in collaborative work processes without causing distraction in health providers' workflows?; c) How can team-based information practices be supported while the boundaries of teams are dynamically changing in the patient care process?; d) How can the tensions between providers who are the producer of the patient care information, and the administrators, researchers and","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"57 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131720289","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}

At run-time, a monitoring system on the smartphone verifies the compliance of the running application against the contract through the Pearson's Chi Squared test. In the preliminary tests, the proposed framework has been able to detect repackaged applications whose behavior is strongly similar to the original application but hide malware.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"206 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131978133","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}
