The type of falling events was determined through the implemented SVM model. The CEP and Event Pattern Matching are then applied to verify the falling event to ensure no false positive result taken place. The results demonstrate that a better performance can be achieved based on the designed algorithm. The quality of images also plays an important role of accuracy.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"15 2 Pt 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131696677","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}

This pen-starting sign is commonly adopted in most of air-writing recognition systems for simplifying the complexity of trajectory matching but often results in inconvenience of usage for users. To tackle this problem, a novel reverse time ordered stroke context is proposed to represent an air-written trajectory in a backward way so that redundant starting-lift data can be effectively filtered out. Then the air-writing recognition problem can be formulated as a path finding problem which is easily solved by a stroke weighting scheme. Another two challenging problems, i.e., the multiplicity problem and the confusion problem also often happen in an air-writing recognition system. The first problem means a character is often written differently among different users. The second problem means different characters often own similar writing trajectory, e.g., {‘b’, ‘p’, ‘D’}. The two problems can be well tackled by introducing a new hierarchical classification scheme which constructs a three-layer structure to represent an air-writing character with different sampling rates. The first layer is designed for tackling the confusion problem by a grouping scheme. The second and third layers are used for dealing with the multiplicity problem of writing styles. All the alphabets (including lowercase, capital, and digital letters) are tested in this system and can be recognized in real time. Performance evaluation shows that the proposed solution achieves quite higher recognition accuracy (more than 94.7%) even though no starting gesture is required.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132178760","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}

When mobile nodes move in highly dynamic networks, they suffer from many challenging issues such as broken network topology and transient connectivity among nodes. In this paper, we propose a geo-routing scheme with an angle-based decision policy (GRAD) for message delivery in delay-tolerant networks. This scheme can select relay nodes in geographic proximity to perform message delivery towards a destination. After a definite number of relays, the message can be destined to a destination. Simulation results show that GRAD can attain a higher rate of successful message delivery and lower communication cost as compared with a classical Spray and Wait scheme under area-confined random waypoint and SLAW mobility patterns in delay-tolerant networks.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131086966","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 “smart home” is one of the most popular topics in the IoT research. We consider that the scale of an IoT-oriented smart home system can go up at the aspects of residential, community and society. Resource allocation and distribution among devices, platforms and services become crucial to system reliability and performance, thus being worth of research efforts in smart home scenarios with IoT support. In this paper, we propose a reference architecture in pursuit of an IoT-based smart home system. Particularly, the home care scenario is deployed to exhibit the scenario on the proposed architecture. Our architecture reference is across front-end to back-end roles in this context, where the home gateway plays the most important role. Accordingly, we design a comprehensive functional home gateway (CFHG) which integrates combined functions of different application strategies on the middleware platform. All data in front-end sensor devices can be aggregated to gateway devices and distributed to cloud storage via web services at the back-end devices, and vice versa, control and management instructions can be issued to any indicated devices to regulate data processing operations. Finally, we make our architecture into effect with practical implementation, and present several usages regarding home care applications.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134431442","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 instructor lectured in English, the STR system generated texts from the voice input, and the CAT system then simultaneously translated the STR-texts into Russian. We aimed to test the feasibility of applying STR and CAT technologies in combination to support learning of Russian speaking students during lectures in English. To this end, we designed an experiment. Three groups with twenty students in each were formed and all students attended the same lectures. Students in a control group attended lectures without any support, students in an experimental group 1 attended lectures with STR support (i.e. they were presented with texts in English generated from the instructor's speech), and students in an experimental group 2 attended lectures with STR and CAT support (i.e. they were presented with texts in Russian translated from English). We compared language ability and post-test results of students in three groups and we surveyed perceptions of students in the experimental group 2 about usefulness of translated texts for their learning. Our results showed that applying STR and CAT technologies was a useful approach; translated texts helped improve learning performance of the experimental group 2 students compared to the control condition significantly. More specifically, translated texts were beneficial both for low and high ability students in the experimental group 2, so that their scores of the tests were much better compared to those of students in the control condition. When students got used to translated texts and found their strength and limitations, they better utilized these texts for their learning. This is why learning progress of students was increasing from Lecture 1 to Lecture 2. Our results also showed that low ability students benefit from translated texts the most; their language ability was lower than that of high ability students before the experiment but after it, learning performance had no significant difference. Finally, most of the students in the experimental group 2 perceived translated texts as useful for their learning and they intended to use them in the future for learning.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128267290","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}

By analyzing the users' historical check-in records, POI recommendation can help users get better visiting experiences by recommending POIs which users may be interested in. Although recent successive POI recommendation methods consider geographical influence by measuring distances among POIs, most of them ignore the influence of the regions where the POIs are located. Therefore, we propose a grid-based successive POI recommendation method, named UGSE-LR, to take the regional influence into consideration when recommending POIs. UGSE-LR first splits an area into grids for estimating regional influence. Then, UGSE-LR applies Edge-weighted Personalized PageRank (EdgePPR) for modeling the successive transitions among POIs. Finally, UGSE-LR fuses user preference, regional preference and successive transition preference into a unified recommendation framework. Experimental results on two real LBSN datasets show that our method is more accurate than the state-of-the-art successive POI recommendation methods in terms of precision and recall.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128490059","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}
