An important issue affecting the efficiency of MEC systems is to determine whether letting the mobile users (MUs) offload the computation tasks to the cloudlet or processing the computation tasks locally. The challenge increases in practical MEC systems when the computation tasks have deadlines and the MUs are moving with intermittent wireless local area network (WLAN) connections. To tackle these challenges, in this paper, we propose a Deadlineaware Online Resource Auction (DORA) framework for dynamic computational resource allocation in MEC systems. In DORA, MUs dynamically evaluates the computational resource at the cloudlets and make bidding and offloading decisions. On the other side, the service provider (SP) carries out a winner selection process to make resource allocation and pricing decisions. The proposed DORA framework is truthful and achieves closeto-offline-optimal time-averaged social welfare with polynomial time complexity. Furthermore, the proposed DORA framework introduces a novel method for online resource evaluation in a stochastic setting. Through rigorous theoretical analysis and comprehensive simulations, we demonstrate the effectiveness of the proposed DORA framework.","PeriodicalId":190096,"journal":{"name":"2018 IEEE International Conference on Pervasive Computing and Communications Workshops (PerCom Workshops)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123093033","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}

Traditional clinical methods for cognitive assessment are conducted by experts once first symptoms appear. Mobile technologies can help supporting more immediate, continuous and ubiquitous measurements, thus potentially allowing for much earlier diagnosis of cognitive disorders. We present in this paper a digital mobile tool to administer cognitive tests in the form of multimedia experience sampling methods (ESM), which can run on a smartphone and can be scheduled and assessed remotely. The tool integrates digital cognitive ESM with passive sensor data that can be used to study the interplay of cognition and physical, social and emotional behaviours. We implement the Mini-Mental State Examination (MMSE) test, a clinical questionnaire extensively used to assess cognitive disorders, in order to showcase the possibilities offered by the proposed tool. Initial usability results show the tool to be perceived simple, easy and accessible for cognitively unimpaired persons.","PeriodicalId":190096,"journal":{"name":"2018 IEEE International Conference on Pervasive Computing and Communications Workshops (PerCom Workshops)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123233468","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}

Innovations like multi-touch displays and virtual keyboards that allow user input by sliding a finger over the letters make this input more and more convenient. However, these systems assume that users have full control over their hand movements. This assumption excludes millions of people who suffer from loss of extremities, paralyses, or spasticities. In this paper, we motivate the urgent need for input mechanisms that make these technologies available for everybody. We focus on gaze-based interaction as eye movements can be tracked by built-in cameras of unmodified mobile devices without any further hardware requirements. As accurate point of gaze estimation on mobile devices is nontrivial, we propose a middleware that is not based on the absolute position of the pupils but rather takes eye movement patterns into account. This paper has four contributions. First, we motivate the need for alternative inputs methods besides manual input. Second, we discuss existing approaches and reveal their limitations. Third, we propose a middleware that allows gaze-based user interaction with mobile devices. Fourth, we provide a framework that allows developers to easily integrate gaze-based control into mobile applications.","PeriodicalId":190096,"journal":{"name":"2018 IEEE International Conference on Pervasive Computing and Communications Workshops (PerCom Workshops)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124458920","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}

Given the growing interest in web-based learning, it is essential to understand if students' needs are met in these learning environments. Sensing mechanisms enable realtime monitoring of students' reactions as they view and engage with course content. We use galvanic skin response and facial expression analysis to identify differences in behaviors associated with learning via a face-to-face versus an online lecture. We also explore the effects of incentives on learning. Findings indicate that physiological data recorded during a lecture is a good indicator of content difficulty, potentially providing a way for instructors to adjust their materials and delivery to benefit students' understanding. The data further suggests that subjects react more negatively to online lecturing and that learning incentives may have the adverse effect of increasing stress on students as opposed to improving performance.","PeriodicalId":190096,"journal":{"name":"2018 IEEE International Conference on Pervasive Computing and Communications Workshops (PerCom Workshops)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126439178","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 the literature, there are many different studies demonstrating the theoretical possibility of performing Transportation Mode Detection (TMD) by mining smartphones embedded sensors data. However, very few of them provide details on the benchmarking process and on how to implement the detection process in practice. In this study, we provide guidelines and fundamental results that can be useful for both researcher and practitioners aiming at implementing a working TMD system. These guidelines consist of three main contributions. First, we detail the construction of a training dataset, gathered by heterogeneous users and including five different transportation modes; the dataset is made available to the research community as reference benchmark. Second, we provide an in-depth analysis of the sensor-relevance for the case of Dual TDM, which is required by most of mobility-aware applications. Third, we investigate the possibility to perform TMD of unknown users/instances not present in the training set and we compare with state-of-the-art Android APIs for activity recognition.","PeriodicalId":190096,"journal":{"name":"2018 IEEE International Conference on Pervasive Computing and Communications Workshops (PerCom Workshops)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134552765","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}
