In this paper, we develop iFridge, an intelligent system which allows the user to effectively manage and accurately locate the foods stored inside the fridge. By leveraging the RFID technology, iFridge is able to automatically collect the food information, perceive the user's activities and locate the specified foods. We develop a smart application \"cooking recipe recommendation\" by sensing the user's daily eating habits. Moreover, by specifying those foods with roughly known locations as anchor nodes, we are able to locate the specified food by using cluster analysis.","PeriodicalId":220524,"journal":{"name":"Proceedings of the 2013 ACM conference on Pervasive and ubiquitous computing adjunct publication","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129175602","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 crowd can contribute with collecting data in the field, completing map information or votes for ideas or products. Even though the participation of large numbers of users with heterogeneous devices in crowdsourcing is a highly recurrent task, generic infrastructures for crowdsourcing can be hardly found. Especially the management of users, mobile devices and contributed data has to be repetitively implemented in new projects. To ease the development of crowdsourcing applications, in this paper we propose a generic platform for crowdsourcing supporting diverse crowdsourcing scenarios, the ability to handle large numbers of users and the involvement of heterogeneous mobile devices. The evaluation is based on scalability and performance experiments in order to demonstrate the feasibility of our approach.","PeriodicalId":220524,"journal":{"name":"Proceedings of the 2013 ACM conference on Pervasive and ubiquitous computing adjunct publication","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116785573","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}

We present the key abstractions, a reference implementation and explain how a typical WoT application can be created using Thing Broker.

As such, speech detection is a fundamental function of many social sensing applications. Simply the amount of speech present in our surroundings can give indications about our socialbility and communication patterns. In this work, we present and evaluate a speech detection approach utilizing dictionary learning and sparse signal representation. Transforming the noisy audio data to the sparse representation with a dictionary learned from clean speech data, we show that speech and non speech can be discriminated even in low signal-to-noise conditions with up to 92% accuracy. In addition to an evaluation with simulated data, we evaluate the algorithm on a real-world data set recorded during firefighting missions. We show, that speech activity of firefighters can be detected with 85% accuracy when using a smartphone that was placed in the firefighting jacket.","PeriodicalId":220524,"journal":{"name":"Proceedings of the 2013 ACM conference on Pervasive and ubiquitous computing adjunct publication","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126025516","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}

Context---as a representation of the environment where the system operates---plays a key role in WSN applications, which must often adapt their operation depending on environmental conditions. We argue that promoting a notion of context as a first-class citizen in WSN programming facilitates the design and implementation of context-dependent functionality. To this end, we conceive a context-oriented programming model expressly tailored to WSNs, coupled with dedicated language constructs. Unlike the existing literature on COP, we embed the latter within low-level C-like languages that do not rely on resource-intensive features such as dynamic memory management. To make our design concrete, we describe a context-oriented extension of nesC---a widely used WSN programming language---and report on a preliminary assessment of our design.","PeriodicalId":220524,"journal":{"name":"Proceedings of the 2013 ACM conference on Pervasive and ubiquitous computing adjunct publication","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127489318","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}
