    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: 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. DeuzeMarc. 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.

    ABSTRACT: The goal of this paper is to compare several indoor and outdoor network models for wayfinding, on their suitability for automatically calculating turns. Automatic turn calculations are of relevance in providing improved cognitive algorithms for route guidance, as it has been widely recognised that routes with minimal angular deviations are easier to follow. It is demonstrated that the currently available indoor network models do not allow accurate calculation of the number of turns along a path, while the common outdoor route networks do. This discrepancy is found to be rooted in an inconsistent definition of indoor decision nodes, which in turn is linked to the inherent differences in space structure between indoor and outdoor environments. Additionally, it is proven that these also have a major influence on the generation of accurate indoor route instructions. Recommendations for future research within the context of both turn calculations and verbalisations of directional changes are made, as well as in the broader context of indoor spatial analyses.

    ABSTRACT: Mobile devices have become increasingly popular in supporting persons to find their ways in our daily lives. Research has been initiated to address issues including the efficiency of wayfinding instructions and the effect of using mobile devices on spatial awareness including cognitive mapping and spatial orientation. In this paper, we present our initial work on the design of mobile map display that visualises distant landmarks at the edge of mobile screen to support spatial orientation. Empirical assessments show that the visualisation of distant landmarks, in comparison with the visualisation without distant landmarks, contributes positively to persons with low sense of direction to be spatially oriented. Furthermore, this design dramatically reduces the frequency of zooming activity on mobile devices. Results indicate the potentials and challenges of extending this design into routing services that could further support user's wayfinding efficiency and spatial awareness.

    ABSTRACT: Location is no longer only a backdrop of mobile device usage, as current location-based services (LBS) can customise content based on a user's geographic position. The application Foursquare has emerged as a leading commercial LBS. One of the first LBS to reach a large, global audience, Foursquare features geosocial networking, place listings, user reviews and recommendations. With physical place as the organising concept of the application, Foursquare combines locative technology with social media features to give users the ability to interact with place by writing place reviews, uploading photos or creating place listings into its database. The application enables users to access, create and share geographically relevant information in ways that would have been difficult before the advent of locative media. To explore how people were using LBS in relation to their places, a small-scale ethnographic study of Foursquare users was conducted using interviews, remote observation and contextual inquiry. The findings of the study indicate that Foursquare users sought, appreciated and made creative use of the application's geographically relevant place information.

    ABSTRACT: In this paper, we give an overview of image matching techniques for various vision-based navigation systems: stereo vision, structure from motion and map-based approach. Focused on map-based approach, which generally uses feature-based matching for mapping and localisation, and based on our early developed system, a performance analysis has been carried out and three major problems have been identified: inadequate geo-referencing and imaging geometry for mapping, vulnerability to drastic viewpoint changes and big percentage of mismatches at positioning. We introduce multi-image matching for mapping. By using affine-scale-invariant feature transform for viewpoint changes, the major improvement takes place on the epoch with large viewpoint changes. In order to deal with mismatches that were unable to be removed by Random Sample Consensus (RANSAC), we propose new method that use cross-correlation information to evaluate the quality of homography model and select the proper one. The conducted experiments have proved that such an approach can reduce the chances of mismatches being included by RANSAC and final positioning accuracy can be improved.

    ABSTRACT: We propose a novel technique for 3D tracking that integrates a single camera and ultrasound. We use ultrasound with the Extended Phase Accordance Method to measure the distance accurately to a moving target and the camera for identifying the 2D position of the target on the image plane. A prototype system consists of a target unit mounting one ultrasound transmitter and three infrared LEDs surrounding it, and a receiver unit with one inexpensive camera and one ultrasound receiver. We implemented these units in a lightweight and compact way (receiver unit size: 55 mm × 44 mm) to make the system robust to non-line-of-sight problems that frequently occur in trilateration or multicamera-based systems. To improve the ranging performance, we applied phase characteristic compensation of the ultrasound transducers by interpolating with a B-spline function and creating a compensated curved surface. Experimental results show that root-mean-square errors of the proposed system are 1.20 mm and 1.66 mm for static and mobile (target velocity: 1.0 m/s) settings, respectively. Thus, the performance of the system is comparable with that of high-end systems. Limitations of the proposed system and its possible applications are also discussed.

    ABSTRACT: We propose a Doppler pose estimation method for an indoor messaging system (IMES) (‘pose’ refers to both position and orientation). With this method, both the position and orientation of a receiver are estimated simultaneously by using Doppler shifts produced by moving a receiver antenna with two or more IMES transmitters. The proposed method is evaluated through the identical experiments conducted in two different locations. In these experiments, the position and orientation of the receiver is estimated using two transmitters, and the achievable accuracy is evaluated by changing the separation distance between the transmitter antennas. The experimental results demonstrate that a positioning accuracy higher than a few decimetres and orientation estimation accuracy of higher than a few degrees are achievable when the measurement condition is relatively good (i.e. when the proper separation distance is set between two transmitter antennas and cycle slips do not occur). We also conducted an analysis for the convergence of initial values (which are used for the iterative position and orientation calculation in the nonlinear least-squares method). The results show that the initial values basically converge to appropriate position and orientation values as long as an inverse matrix in the position and orientation estimation process can be calculated. Moreover, we analysed the effect of the number of transmitters on position and orientation estimation precision. The results show that, as the number of transmitters increases, the precision of the position and orientation estimation also increases, and the precision is particularly high in the area surrounded by the transmitters.
