Furthermore, we often acquire content for a specific purpose, i.e., the acquisition of a phone number to place a call. We have developed a content transfer concept, Eye Drop. Eye Drop provides techniques that allow fluid content acquisition, transfer from shared displays, and local positioning on personal devices using gaze combined with manual input. The eyes naturally focus on content we desire. Our techniques use gaze to point remotely, removing the need for explicit pointing on the user's part. A manual trigger from a personal device confirms selection. Transfer is performed using gaze or manual input to smoothly transition content to a specific location on a personal device. This work demonstrates how techniques can be applied to acquire and apply actions to content through a natural sequence of interaction. We demonstrate a proof of concept prototype through five implemented application scenarios.","PeriodicalId":286368,"journal":{"name":"Proceedings of the 12th International Conference on Mobile and Ubiquitous Multimedia","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116369004","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 addition to advertising they often provide information related to the location (e.g., time tables). However, individuals can have difficulties to find information relevant to them -- either due to information overload or lack of personalization. Multiplexing, as defined in information theory, can help to address this issue by increasing the number of available channels. We propose three methods for visual multiplexing, and report on a controlled lab-based comparison study. Our results indicate that visual multiplexing via mobile devices can be a feasible solution to provide personalized multimedia content on public displays, and that the three methods tested differ in terms of performance. We found that the content type shown has an impact on which method works best, and that self-reported workload differed according to content type and multiplexing method.","PeriodicalId":286368,"journal":{"name":"Proceedings of the 12th International Conference on Mobile and Ubiquitous Multimedia","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122637875","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}

Despite being widely used to track navigation, clicks, cursor moves or eye gaze, heat maps have not yet been explored as a means to understand users' gestural interaction with mobile devices. This understanding is particularly relevant in the case of older adult users who are often novice users and may also struggle with accuracy in gesture performance. This paper explores the application of the DBScan clustering algorithm to uncover the most relevant swipe gestures in a data sets containing the user interaction of two mobile applications. An intuitive visualization of the clustering results will be presented and compared in a case study with a heat map visualization, discussing the novelty and usefulness of these visualizations for user behaviour and usability studies.","PeriodicalId":286368,"journal":{"name":"Proceedings of the 12th International Conference on Mobile and Ubiquitous Multimedia","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125554484","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}

Although results of preliminary studies are promising, researchers tend to use high sampling rates in order to obtain adequate recognition rates with a variety of sensors. What is not fully examined yet, are ways to integrate into this the information that does not come from sensors, but lies in vast data bases such as time use surveys. We examine using such statistical information combined with mobile acceleration data to determine 11 activities. We show how sensor and time survey information can be merged, and we evaluate our approach on continuous day-and-night activity data from 17 different users over 14 days each, resulting in a data set of 228 days. We conclude with a series of observations, including the types of activities for which the use of statistical data has particular benefits.","PeriodicalId":286368,"journal":{"name":"Proceedings of the 12th International Conference on Mobile and Ubiquitous Multimedia","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115631342","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 demonstrate that locality does have a significant effect on the game-play especially when the player can actually see the familiar surroundings in the game world.

An alternative approach is mining existing online crowd-sourced repositories for open-ended, free annotated training data. However, differences across data sources or in observed contexts prevent a crowd-sourced based model reaching user-dependent recognition rates. To enhance the use of crowd-sourced data in activity recognition, we take an essential step forward by adapting a generic model based on crowd-sourced data to a personalized model. In this work, we investigate two adapting approaches: 1) a semi-supervised learning to combine crowd-sourced data and unlabeled user data, and 2) an active-learning to query the user for labeling samples where the crowd-sourced based model fails to recognize. We test our proposed approaches on 7 users using auditory modality on mobile phones with a total data of 14 days and up to 9 daily context classes. Experimental results indicate that the semi-supervised model can indeed improve the recognition accuracy up to 21% but is still significantly outperformed by a supervised model on user data. In the active learning scheme, the crowd-sourced model can reach the performance of the supervised model by requesting labels of 0.7% of user data only. Our work illustrates a promising first step towards an unobtrusive, efficient and open-ended context recognition system by adapting free online crowd-sourced data into a personalized model.","PeriodicalId":286368,"journal":{"name":"Proceedings of the 12th International Conference on Mobile and Ubiquitous Multimedia","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127711184","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}

While the first approach arranges the facets in a 3x3 grid, the second approach makes use of a scrollable list of facets for exploring the data. As concrete scenario, we use category hierarchies that are dynamically obtained from different, distributed social media sources. We have conducted a between-group experiment of the two approaches with 64 subjects (41 male, 23 female) executing the same set of tasks of typical mobile users' information needs. The results show that subjects using the grid-based approach require significantly more time and more clicks for completing the tasks. However, regarding the subjects' satisfaction there is no significant difference between the two approaches. Thus, if efficiency is not the primary objective, the grid-based approach might be of interest as it provides a navigation element that allows the users to see the exact position in the data space. This might be a very useful feature in scenarios where knowing the exact position is quite crucial such as browsing classification schemas in digital libraries or other formal taxonomies.","PeriodicalId":286368,"journal":{"name":"Proceedings of the 12th International Conference on Mobile and Ubiquitous Multimedia","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132625965","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}

To avoid making the user precisely align the barcode at a dedicated position and angle in the camera image, barcode localization algorithms are necessary that quickly scan the image for possible barcode locations and pass those to the actual barcode decoder. In this paper, we present a barcode localization approach that is orientation, scale, and symbology (1D and 2D) invariant and shows better blur invariance than existing approaches while it operates in real time on a smartphone. Previous approaches focused on selected aspects such as orientation invariance and speed for 1D codes or scale invariance for 2D codes. Our combined method relies on the structure matrix and the saturation from the HSV color system. The comparison with three other real-time barcode localization algorithms shows that our approach outperforms the state of the art with respect to symbology and blur invariance at the expense of a reduced speed.","PeriodicalId":286368,"journal":{"name":"Proceedings of the 12th International Conference on Mobile and Ubiquitous Multimedia","volume":"273 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121208508","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}
