It represents high levels of data and a strong focus on the user itself by encompassing dynamical environments with contextual data and by offering several interaction modalities. In such scenarios, traditional question-answer processes fail short to retrieve the necessary amount of data for more comprehensive evaluations. In this paper, we propose an enhanced evaluation approach adapted to these new demands. The proposal follows a user-centric approach and provides an integrative platform for evaluators to gather more information. This platform is characterized by a reusable enquiry module, its ability for real time monitoring and a event-driven dynamic module for adaptable evaluation processes. As a proof of concept, a concrete scenario based on a telerehabilitation application is also presented.","PeriodicalId":192421,"journal":{"name":"Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"57 46","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120885455","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 mobility of the information sink means that the protocol must quickly adapt to a constantly changing view of the network, where connections and disconnections are the norm. Our protocol is purely sink driven, that is, the sink controls congestion by rate limiting the sensors, choosing how to assign the available bandwidth to different sensor types and deciding on the level of reliability to be achieved. In addition, our protocol operates at the application layer with minimal requirements from lower layers, allowing its integration with a disaster recovery application that will set its parameters depending on the disaster scenario. As a result, our protocol allows simple and inexpensive fixed sensors to be combined with expensive but reusable mobile equipment for disaster recovery purposes.","PeriodicalId":192421,"journal":{"name":"Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122634813","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 this paper, we explore two different but complementary approaches to extracting useful information from electronic patient records with the goal of identifying candidate drugs, or combinations of drugs, to be further investigated for suspected adverse drug events. We propose a novel filter-and-refine approach that combines sequential pattern mining and disproportionality analysis. The proposed method is expected to identify groups of possibly interacting drugs suspected for causing certain adverse drug events. We perform an empirical investigation of the proposed method using a subset of the Stockholm electronic patient record corpus. The data used in this study consists of all diagnoses and medications for a group of patients diagnoses with at least one heart related diagnosis during the period 2008--2010. The study shows that the method indeed is able to detect combinations of drugs that occur more frequently for patients with cardiovascular diseases than for patients in a control group, providing opportunities for finding candidate drugs that cause adverse drug effects through interaction.","PeriodicalId":192421,"journal":{"name":"Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"226 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123036226","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 results indicated that human factors often coexist with parameters related to the condition of the ship and other external factors (i.e. bad weather). Our investigation aims to contribute to the better understanding of underlying factors so that more targeted staff training, manning and shipping maintenance measures can be taken to prevent future events.","PeriodicalId":192421,"journal":{"name":"Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115143514","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 use of novel technology to support rehabilitation is increasing in popularity, with some evidence that it may be able to decrease the perception of pain, and improve movement quality, engagement and compliance with therapy. However, indiscriminate use of off-the-shelf games technology or haphazard approaches to the design of rehabilitation applications and virtual environments may not only reduce the potential benefits, but may even exacerbate the underlying problems. We consider the potential and the pitfalls associated with the use of novel technology in virtual reality rehabilitation, and suggest some strategies for reducing the risks and optimising therapeutic outcomes in virtual environments.","PeriodicalId":192421,"journal":{"name":"Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124637695","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 this paper we assess the feasibility of using a popular commercial skeleton tracking software solution in a large vocabulary gesture recognition system using an RGB-D gesture dataset. We also provide a discussion of where improvements in existing methods utilizing the advantages of depth-sensing technology can be made in order to achieve the best possible results in complex gesture recognition.","PeriodicalId":192421,"journal":{"name":"Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122592738","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}

Assistive technology is often see as a potential answer to this issue that may help giving more autonomy to these people. This paper presents a new assistive system for smart homes, which is based on the analysis of electrical load signatures at the steady-state, in order to provide supervision and assistance in carrying out activities of daily living for people with cognitive impairment. The proposed system exploits a new algorithmic approach to determine the erroneous behavior related to cognitive deficits and to guide the person through the completion of his ongoing task. We implemented and deployed our system in a real size smart home prototype where we used only a single power analyzer at the main electric panel which is invisible to end-users. Then, a complete experiment has been conducted on this new assistive system using breakfast sequences reproduced with electrical appliances. The simulated sequences included some cognitive errors modeled from real case scenarios coming from previous experiments with Alzheimer patients. The system showed very promising and robust results, both for activity recognition and guidance. It demonstrated that it is possible, using nonintrusive hardware like a simple power analyser, to compete with other assistive systems presented in the literature, which require intrusive equipment to properly monitor and guide.","PeriodicalId":192421,"journal":{"name":"Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116531130","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}

Kontogiannis, Panos Psaros","doi":"10.1145/2674396.2674462","DOIUrl":"https://doi.org/10.1145/2674396.2674462","url":null,"abstract":"The introduction of new air traffic management systems changes the demands on the provision of Air Traffic Control (ATC) services. At the core of the system air traffic controllers are responsible for the safe, expeditious and orderly flow of the air traffic. The growth of air traffic requires an increase in the capacity of the airspace, controller tools, and operating procedures. In the case of modern ATC operations, we are dealing with a complex; information rich and dynamic environments that require air traffic controllers to attend to multiple events anticipate aircraft conflicts, implement new concepts and make sense of evolving scenarios. Major system wide interventions; the Single European Sky Air Traffic Management Research (SESAR) and Next Generation Air Transportation System (NextGen) present significant changes to the delegation of authority between pilots and controllers, which requires further research on how controllers employ failure sensitive strategies in complex scenarios. Failure sensitive strategies in the context of Cognitive Systems Engineering refer to higher level strategies related to macrocognitive processes (e.g., problem solving), which are supported by the same automation functions as normal operations. High-level strategies are essential in keeping the system safe, and include strategies that forestall possibilities for failure. Normal day-today operations require conflict resolution strategies and abnormal situations call for high-level strategies. Studying how controllers employ failure sensitive strategies to cope with traffic complexity is very important if we are to understand how modern information technology and new operational demands may affect system performance. To this end, an observational field study was performed during the annual refresher training of Air Traffic Controllers in a medium complexity European airport with seasonal traffic. This was later complemented with a follow up small scale trail on simulator training to corroborate initial findings. The purpose of the study was to explore the capabilities of existing simulator based training in monitoring and evaluating failure-sensitive strategies in normal operations where new concepts are employed. Initial results indicated that current simulators can be a useful tool in monitoring and evaluating failure sensitive strategies without substantial alterations of their characteristics and in line with training curricula. In a first level and using cognitive task analysis failure sensitive strategies were elicited and documented. In a second level, a set of user centred requirements was compiled towards the development of a low cost debriefing tool based on existing simulators and training practices. In a third and final level a complexity metrics was developed in order to define thresholds of cognitive complexity that prevent controllers from full implementation of new concepts on day to day operations. Practical benefits can be derived especially i","PeriodicalId":192421,"journal":{"name":"Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125732416","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}
