Abstract. Due to their intuitiveness, 3D mobile maps have recently emerged as an alternative to 2D mobile maps. However, designing interactions for navigation in a 3D environment using a mobile device is non-trivial. Challenges are posed by the severe limitations of the mobile user interface and of the capacities of the mobile user. This chapter analyses the problem of degrees of freedom: how to make navigation quicker and more intuitive by the means of restricting and guiding movement, yet enabling unrestricted access to all reasonable points-of-interests. Insights from empirical studies of mobile map interaction are presented, in the form of a model of interactive search, to draw requirements for interaction design. Then, the design of controls, landmarks, cameras, interest fields, routes, paths etc. are analysed and several higher-level navigation metaphors are discussed. We propose ways to support spatial updating, rapid alignment of physical and virtual spaces, and overcoming the keyhole problem. A working prototype system is used to illustrate different solutions alongside with alternative designs, weighing their pros and cons.

“…This means that a general-purpose navigation system must be able to integrate with different kinds of positioning technologies. Most of the literature on indoor pedestrian navigation [11], [12], [18], [21] put the main focus on how to obtain reliable and accurate positions by means of UWB, dead reckoning, WiFi positioning etc., whereas less effort is put into providing a well-structured and efficient navigation functionality, or efficient navigation interfaces. The PerPos [8] platform provides cloud services that, e.g., take care of providing the most accurate position possible, given the positioning hardware and the building conditions, as well as offering location model and route planning services.…”

“…The primary focus of the literature on indoor pedestrian navigation is on the positioning methods [11], [12], [18], [21]. These papers, although talking about navigation, are more about achieving accurate positions indoor by means of dead reckoning, WiFi, Particle filters and similar approaches.…”

Abstract. This paper introduces methods and services called PerPosNav for development of custom indoor pedestrian navigation applications to be deployed on a variety of platforms. PerPosNav is built on top of the PerPos positioning middleware [8] that fusions GPS, WiFi and inertial tracking into indoor positioning with high accuracy in many types of buildings. The challenges of indoor navigation are discussed and the PerPosNav services are introduced. PerPosNav combines symbolic and geometry based modeling of buildings, and in turn combines graph-based and geometric route computation. The paper argues why these hybrid approaches are necessary to handle the challenges of indoor pedestrian navigation. Furthermore, a fluent navigation is maintained via route tracking and navigation services that generate instructions based on how the user moves in relation to the prescribed route. The viability of PerPosNav has been proven by implementation of support for multiple modes of pedestrian indoor navigation: 1) augmented signs, 2) map based navigation on smartphones, 3) auditory navigation on smartphones solely via earbuds, and 4) augmented reality navigation. Experiences from the use of the PerPosNav services are discussed and compared to other indoor pedestrian navigation approaches.

Abstract:In this paper we provide a critical overview of the state of the art in human-centric intelligent data management approaches for geographic visualizations when we are faced with bandwidth limitations. These limitations often force us to rethink how we design displays for geographic visualizations. We need ways to reduce the amount of data to be visualized and transmitted. This is partly because modern instruments effortlessly produce large volumes of data and Web 2.0 further allows bottom-up creation of rich and diverse content. Therefore, the amount of information we have today for creating useful and usable cartographic products is higher than ever before. However, how much of it can we really use online? To answer this question, we first calculate the bandwidth needs for geographic data sets in terms of waiting times. The calculations are based on various data volumes estimated by scholars for different scenarios. Documenting the waiting times clearly demonstrates the magnitude of the problem. Following this, we summarize the current hardware and software solutions, then the current human-centric design approaches trying to address the constraints such as various screen sizes and information overload. We also discuss a limited set of social issues touching upon the digital divide and its implications. We hope that our systematic documentation and critical review will help researchers and practitioners in the field to better understand the current state of the art.
