This paper proposes ORB-visual-odometry positioning estimation and wall-floor-boundary image registration to make ARN more precise, reliable, and instantaneous. Experimental results show both ORB-visual-odometry positioning estimation and wall-floor-boundary image registration have higher accuracy and less latency than conventional well-known positioning estimation and image registration methods for ARN. On the other hand, these proposed two methods are seamlessly implemented on the handheld Android embedded platform and are smoothly verified to work well on the handheld indoor/outdoor augmented reality navigation device.","PeriodicalId":259542,"journal":{"name":"2019 Twelfth International Conference on Ubi-Media Computing (Ubi-Media)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115246415","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}

Meanwhile, edge device has complex structure and weak storage capacity. A lot of security threats still exist in the process of storing sensitive data. This paper proposes a method of combining fountain code and XOR encryption to the data storage in edge devices. First, the source file is encrypted by XOR encryption. Then we divide the ciphertext into multiple ciphertext data blocks. After encoding ciphertext data blocks, we mix them with coding blocks and distribute them on multiple edge devices. When we receive enough data blocks, we can recover the source file. The combination of XOR encryption and fountain code improves reliability and security of storage.","PeriodicalId":259542,"journal":{"name":"2019 Twelfth International Conference on Ubi-Media Computing (Ubi-Media)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129770579","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 acceptability and usability of a system can be enhanced when the user emotions are considered based on the context. Most of the past research has been carried out related to the detection of emotions using facial expressions, gaze direction, heart rate analysis, Electroencephalogram (EEG) signals, text analytics, and keystroke dynamics along with mouse movements. This paper is a literature review which summarizes the previous research work in order to identify the critical success factors of the existing approaches when detecting user emotions through facial expressions and text data along with the context. Finally, as a conclusion, considering the advantages and drawbacks of the existing applications, the novel approaches that need to be followed to analyse user emotions to improve the usability of systems are proposed.","PeriodicalId":259542,"journal":{"name":"2019 Twelfth International Conference on Ubi-Media Computing (Ubi-Media)","volume":"380 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123506017","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 goal was to compare how these two technologies help achieve this important task. To this end, two groups of students were recruited to attend two lectures (one at the intermediate and the other at the advanced level). STR-texts were shown to a control group while SELT-texts were shown to an experimental group. We compared the cognitive load of the students in both groups after each lecture. Our findings revealed that between-group difference in cognitive load was not significant; however, if student language ability was considered, a significant between-group difference existed during the advanced level lecture. We draw implications for researchers and teachers following these results.","PeriodicalId":259542,"journal":{"name":"2019 Twelfth International Conference on Ubi-Media Computing (Ubi-Media)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121889056","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}

Furthermore, higher educational institutes are finding solutions to create more personalized learning environments. There is an opportunity to improve the learning environment by applying Learning Analytics to educational data generated by learners interacting with Virtual Learning Environments (VLEs) and other digital learning tools. More personalized learning environments can be implemented by applying Learning Analytics on Learning Designs. Students' learning progress can be captured through Learning Dashboards in real-time by applying Learning Analytics during the course run-time. We can improve Blended Learning through the synergy between Learning Analytics and Learning Design.

The new motion-sensing technology, Kinect, is cost effective and does not require the patient to wear sensors on the body, which increases freedom of movement. The objective of this study was to use Kinect technology to develop a VR stroke rehabilitation system with unilateral and bilateral tasks for recovering the function of the upper extremity. This study tested the feasibility, therapeutic effectiveness, and user acceptance of this technology. Two participants with various levels of motor severity received 30-minute stroke rehabilitation 3 times per week over 8 weeks (a total 24 training sessions). The Wolf Motor Function Test (WMFT), Test Évaluant la performance des Membres supérieurs des Personnes Âgées (TEMPA), and Fugl-Meyer Assessment of Physical Performance (FMA) were used to collect data before and after rehabilitation, and during a follow-up to detect the changes of functional performance. Questionnaires of user acceptance of the technology were administered. On completion of the rehabilitation program, using the proposed Kinect-based VR training system, WMFT, TEMPA, and FMA results increased for both participants. The technology acceptance questionnaires indicated that participants had strong intentions to continue using the proposed system for rehabilitation. We developed the first Kinect-based stroke rehabilitation for the upper extremity, and demonstrated its feasibility and effectiveness in improving upper extremity function after a stroke. A large-scale study should be conducted to test the effectiveness of the proposed system for stroke rehabilitation.","PeriodicalId":259542,"journal":{"name":"2019 Twelfth International Conference on Ubi-Media Computing (Ubi-Media)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126528862","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}
