    ABSTRACT: The advancement of GPS technology has made it possible to use GPS devices as orientation and navigation tools, but also as tools to track spatio-temporal information. GPS tracking data can be broadly applied in location-based services, such as spatial distribution of the economy, transportation routing and planning, traffic management and environmental control. Therefore, knowledge of how to process the data from a standard GPS device is crucial for further use. Previous studies have considered various issues of the data processing at the time. This paper, however, aims to outline a general procedure for processing GPS tracking data. The procedure is illustrated step by step by the processing of real-world GPS data of car movements in Borlänge in the centre of Sweden.

    ABSTRACT: The relationship between cultural heritage domain and new technologies has always been complex, dialectical and often inspired by the human desire to induce these spaces not created for that purpose, to pursue technological trends, eventually offering to the end-users devices and innovative technologies that could become a ‘dead weight’ during their cultural experiences. However, by means of innovative technological applications and location-based services it is possible to shorten the distance between cultural spaces and their visitors, nowadays determined by the purely aesthetic and essentially passive fruition of cultural objects. This paper presents the design and implementation of a novel multipurpose system for creating single smart spaces (), a new concept of intelligent environment, that relies on innovative sensors board named smart crickets and an ad hoc proximity strategy; by following the Internet of Things paradigm the proposed system is able to transform a cultural space in a smart cultural environment to enhance the enjoyment and satisfaction of the involved people. To assess the effectiveness of our solution, we have experienced two real case studies, the first one situated within an art exhibition (indoor), and the second one concerning an historical building (outdoor). In this way, technology can become a mediator between visitors and fruition, an instrument of connection between people, objects and spaces to create new social, economic and cultural opportunities.

    ABSTRACT: This paper presents methods for inferring selected travel patterns using passive cell-phone technology. The paper handles two issues that are related to the cellular phone technology: ‘zigzagging’ patterns that do not represent a movement, and track recording of the closest antenna location that serves the cell-phone, which means that the information of the location of the cell-phone itself is not accurate. The home and commuter location of each user is validated at the aggregate district level. The paper shows selected results that can be used for transportation analysis, including a comparison of the results to known models from preceding years.

    ABSTRACT: A fundamental goal of indoor localisation technology is to achieve the milestone of combining minimal cost with accuracy sufficient enough for general consumer applications. To achieve this, current indoor positioning systems need either extensive calibration or expensive hardware. Moreover, very few systems built so far have addressed floor determination in multi-story buildings. In this paper, we explain a Wi-fi-based indoor localisation, tracking and navigation system for multi-story buildings called Locus. Locus determines a device’s floor as well as location on that floor using existing knowledge of infrastructure, and without requiring any calibration or proprietary hardware. It is an inexpensive solution with minimum set-up and maintenance expenses, is scalable, readily deployable and robust to environmental changes. Experimental results in three different buildings spanning multiple floors show that it can determine the floor with 95.33% accuracy and the location on the floor with an error of 6.49 m on an average in real-life practical environments. We also demonstrate its utility via two location-based applications for indoor navigation and tracking in emergency scenarios.

    ABSTRACT: The wide adoption of mobile devices and streaming music services has paved the way for location-based music services. However, there has not yet been any commercial breakthrough. We designed OUTMedia, a location-sensitive music discovery application with unique features, to explore rewarding user interactions. This article reports the design efforts and a field study of the functional prototype. We utilised user interviews, log data and the ResQue instrument to study use and user experience of the prototype. All measures found the overall concept feasible and the use of the application resulted in serendipitous experiences of music and places. Our findings call for service designers to support the interplay between media and places in personal meaning-making processes, to enrich urban cultural experiences with user-created information layers that accumulate over time. The design implications can be used to support serendipitous music experiences through the interplay between places and media in future content discovery services.

    ABSTRACT: Interacting with an application for shared mobility is a complex spatio-temporal task, considering the degrees of freedom in planning and preferences together with the dynamics of supply. Traditional approaches also rely on the disclosure of inherently private, discrete information from both vehicle and client to perform ride matching. Catering for both aspects, we have previously suggested an intuitive interface concept, launch pads. In this paper we extend launch pads by enhancing the visualisation in a third dimension. This representation provides a client with a more detailed choice set which should lead to improved decision-making. To examine the value of this enhancement, we implement a multi-agent simulation and observe a client agent's responses to 3D launch pads visualised according to three different fare models. Results show that a client's flexibility in space is dependent on the fare model chosen, and it is this offering which can increase a client's utility.

    ABSTRACT: The widespread availability and the technological advancement of geo-positioning devices enable users to generate a high volume of geo-tagged objects everyday. These objects include points of interests, photos, and buying/selling items. To describe such an object, which is commonly referred as a spatial object, users often use textual description or keywords along with the geographic location of the entity. Based on these geo-tagged objects, a large variety of location-based services has been emerged. For example, a user may want to find an Italian restaurant nearest to his location. We envision a new set of applications that require incorporating time along with location and textual information, e.g. find the Italian restaurant nearest to my location, which opens at 10 pm today. We term this type of query as a spatio-temporal keyword (STK) query. A straightforward way of answering STK queries using an existing spatial keyword search technique requires retrieving objects that are not temporally relevant to the query time. To solve this issue, in this paper, we introduce a new index structure that hierarchically organises time along with location and keywords, and develop an efficient algorithm for processing STK queries. We also extend our work to handle time uncertainty in STK queries. An extensive experimental study shows the efficiency and effectiveness of our proposed techniques.

    ABSTRACT: With the prevalence of mobile computing systems and location based services, large amounts of spatio-temporal data are nowadays being collected, representing the mobility of people performing various activities. However, despite the increasing interest in the exploration of these data, there are still open challenges in various application contexts, e.g. related to visualisation and human–computer interaction. In order to support the extraction of useful and relevant information from the spatio-temporal and the thematic properties associated with human trajectories, it is crucial to develop and study adequate interactive visualisation techniques. In addition to the properties of the visualisations themselves, it is important to take into consideration the types of information present within the data and, more importantly, the types of tasks that a user might need to consider in order to achieve a given goal. The understanding of these factors may, in turn, simplify the development and the assessment of a given interactive visualisation. In this paper, we present and analyse the most relevant concepts associated to these topics. In particular, our analysis addresses the main properties associated with (human) trajectory data, the main types of visualisation tasks/objectives that the users may require in order to analyse that data and the high-level classes of techniques for visualising trajectory data. In addition, this paper also presents an overview on a user study, conducted in function of this analysis, to compare two classes of visualisation techniques, namely static maps and space-time cubes, regarding their adequacy in helping users completing basic visualisation tasks.

    ABSTRACT: In this article, we describe a low-cost indoor navigation system, based on the capabilities of modern smartphones commonly equipped with accelerometer, gyroscope, camera and Internet connection. The main claim of this paper is that, relaxing the requirement of best accuracy, with an intelligent use of inertial sensors, digital maps, and ambient tagging, it is still possible to get good results. Our mobile application helps the user in retrieving directions and finding places in large indoor environments where the global positioning system (GPS) is not available, such as airports, hospitals, museums and so on. The goal is to get a system able to work without the use of any physical ad hoc infrastructure and without relying on any wearable device. We name our infrastructure-free system Roodin, and its features are as follows: user-friendly interface, quick install and calibration tool, point-of-interest search and guidance. All the features presented in this paper are designed and implemented, and the application has been evaluated with real users. A summary of user evaluation is reported in the paper.

    ABSTRACT: In this paper we introduce an advanced platform to label mobile event data with significant subscriber locations in real time. The presented platform is divided into two sections – the learning section and the real-time processing section. During the real-time processing step, we enrich live event streams with significant locations calculated in the learning step using stream and call detail record data. We validate our system by comparing a sample of subscribers' calculated locations with actual locations and give state benchmarks for minimum event counts. The validation confirms that the platform works within desired deviation levels from real locations. The accuracy strongly depends on the event count that we can take into account. Finally, we simulate a real-world scenario and measure the real-time labelling performance of our system. The results of this simulation confirm that our event labelling platform performs sufficiently well to process real event streams for millions of subscribers in real time.

    ABSTRACT: The seamless integration of smartphones in the everyday practices and routines of people is a typical example of the ‘disappearance of media’ (Deuze 201212. Deuze, Marc. 2012. Media Life. Cambridge, MA: Polity Press.View all references). Although the actual device is currently still very tangible and visible, it can be defined as the first step in the direction of a world that exists out of Internet-connected objects and people. With the increasing adoption of smartphones, location-based social networks (LBSNs) and platforms gain widespread popularity. However, these context-aware applications also bring along new privacy concerns. Privacy practices now take place in a context in which multiple contextual factors define the interplay between the technology and user. In this article, we study this mutual shaping between LBSNs and mobile users' privacy practices from a Science & Technology Studies perspective and following the work of Madeleine Akrich (1992). We explore how the user script, or the design and features of the LBSNs, can frame users' privacy practices, but also how users invent new ways to manage their privacy beyond the embedded user script. A qualitative user study was conducted to study users' location-sharing behaviour along the privacy-related user scripts (privacy scripts). In this study, couples of friends were asked to use and execute tasks with two different types of LBSNs. Results indicate that the privacy script of a technology influences users' perceived control over their personal information. Although perceived control does not always reflect the actual control, this can mitigate privacy concerns, and as a consequence, also influence users' privacy practices.

    ABSTRACT: Vehicle routing usually depends on a road map, and road maps are expensive to create and maintain. While crowdsourcing road maps from logged GPS data has proven effective, the limited availability of GPS data limits their coverage area. To overcome this limitation, we show how to use location data from geotagged tweets, which cover much of the world, to compute routes directly without making a road map. We compensate for the wide spacing of tweets' latitude/longitude points by using probabilistic time geography, which explicitly models the uncertain location of someone traveling between measured locations. In our formulation, each pair of temporally adjacent tweets contributes an estimate of the driving time along hypothesised roads in a regular grid. We show how to compute these estimates as expected values based on probabilistic Brownian bridges. We can compute routes on this regular grid using traditional A* search. Our experiments demonstrate that our computed routes match well with routes computed on the actual road network using a commercial router. Furthermore, we show that our computed routes vary sensibly with changes in traffic between rush hour and weekends. We also apply the same technique to compute reasonable airplane routes.

    ABSTRACT: Applications of new technology in travel surveys have demonstrated the possibility to obtain good quality activity data than traditional survey methods. However, the quality of the imputation diary data highly depends on the predictability of data processing algorithms, which are not fully ready yet. Narrowing the gap between imputation results and true activity–travel patterns is necessary to improve the ease of data confirmation in prompted recall surveys and develop fully automatic data imputation systems. This paper proposes an algorithm to decrease the discrepancies between imputed activity–travel diary and the so-called ground truth. Based on the activity–travel pattern obtained using a Bayesian belief network model, the algorithm takes into account the consistency of the full activity–travel pattern within a day in the sense that the activity–travel sequence is represented in terms of a hierarchical set of tours, and the transportation modes within a tour are logically consistent. We explore three different approaches based on the frequency at the trip/tour level and imputation probability at the epoch level, for each transportation mode. Results obtained based on the test using GPS data in the Netherlands show that the new algorithm significantly improves the imputation accuracy of transportation modes compared with an algorithm that does superimpose these pattern constraints.

    ABSTRACT: Tourist recommendation services provide suggestions for places of interest. While the spatial structure of a tourist's visit has been successfully exploited to improve the quality of place recommendations, its temporal structure has not been taken into account so far. This is surprising because the importance of the visitors' time management is well known from tourism research. We present findings of an empirical study that sheds light on the temporal aspects of tourist exploration behaviour and discuss implications for the design of tourist-recommender systems. The data-set consists of interviews, GPS tracks and geo-referenced photo sequences from visitors of a typical Middle European destination for cultural tourism. Among the results relevant to place recommending are the following: (1) the set of places is often replanned during the visit; (2) comparing place popularity based on photo frequency and place popularity based on staying time, we found notable differences in rank ordering; and (3) the photo frequency and the detour sinuosity of the GPS tracks are decreasing slowly over time. We interpret this last finding as a time-geographic cone effect. Based on the empirical results, we discuss the implications for the design of tourist-recommending services and propose a corresponding user interface utilising a recommendation strategy that tries to counterbalance the time-geographic cone effect, that is, to decelerate the visiting experience.

    ABSTRACT: Volunteered geographic information (VGI) data-sets are characterised by heterogeneity due to influences from technical, social, environmental or economic factors. As a result, mapping progress does neither follow a spatially nor a temporally equal distribution, and thus can be hardly measured or predicted. Positively stated, heterogeneity leads to interesting VGI data-sets revealing regional peculiarities such as diverse community activities. This work proposes an approach for identifying regionally and temporally different developments with respect to mapping progress. Regional mapping progress is measured with a modified version of a previously proposed model for classifying activity stages, which has been used as foundation for a massive spatial and temporal analysis of the worldwide OpenStreetMap contributions between the years 2006 and 2013. It also allows the evaluation of rural and unpopulated areas. Results reveal that regional mapping progress heavily depends on a number of distinct influences such as geographical or legal borders, data imports, unexpected events or diverse community developments. The work highlights regions with distinct results by revealing individual mapping stories.

    ABSTRACT: Studies in the field of pedestrian navigation have shown advantages of map–image combinations. While in a previous work, the map view was either replaced with an image view in predefined situations, or the user was required to manually switch between both views, we suggest to use a split screen displaying maps and images at the same time. We developed two variants, one employing panoramic images aligned to the mobile device's orientation and the other using simple photographs, and we evaluated both against manual switching in a field study. While none of the interfaces outperformed the other, results indicate advantages of panoramic images independent of manual switching or the split screen.
