Pathway analysis provided by current 3D maps in mobile devices that are intended for an interactive navigation aid, is simulated for what-if experiments against task and functional analysis, based on the problems faced from both technical and user-practices views. The aim of a navigation aid, in general, is to provide an optimal route from the current position to the destination. Unfortunately, the problem of most mobile device’s GPS signal accuracy and the display of pathways on 3D maps in the small screen of mobile devices affects the pathway architectural design from generating accurate initial positions to destinations. This paper presents both conceptual and experimental analysis of pathway determination designed for 3D maps in mobile devices for an interactive navigation aid, which is going to be added to an existing individual cognitive map. The analytical outcomes are aimed at providing how environmental conditions come to be detected and how problems are resolved in helping people to navigate in unfamiliar locations by having positions and paths corrected to a reasonable degree of accuracy in order to overcome the problems of generating in-accurate locations and the weaknesses of conventional 2D maps, which requires users to interpret its various symbols and legends. Bent functions and fuzzy logic type 2 are used for simulating signal deviations from the precise values and Voronoi diagram/Delaunay triangulation are used for establishing experimental paths and locations. Finally, this technique will contribute to a well-defined positioning and pathway establishment of 3D maps in mobile devices for navigation aid.

3D maps have become an essential tool for navigation aid. The aim of a navigation aid is to provide an optimal route from the current position to the destination. Unfortunately, most mobile devices' GPS signal accuracy and the display of pathways on 3D maps in the small screen of mobile devices affects the pathway architectural from generating accurate initial positions to destinations. This chapter proposed a technique for visualizing pathway on 3D maps for an interactive user navigation aid in mobile devices. This technique provides visualization of 3D maps in virtual 3D workspace environments which assists a user to navigate to a target location. The Bi-A* path-finding algorithm was used for establishing dynamic target location in Voronoi diagram/Delaunay triangulation. This approach could navigate more than two users in a 3D walk-space and at the same time showing their whereabouts on 3D projections mapped. The map shows the users' location in the scene to navigate from source to the target and the target also moves to the source to meet on the same physical location and image plane.

With the increased usage of mobile devices, society is seeing more and more users doing transactions wirelessly. Often, data from a single server may not be sufficient. Rather, data may need to be manipulated and to be gathered from multiple remote servers before useful information can be formed. Mobile transactions are constrained by small screen size of mobile devices, high communication cost, and high memory consumption. Existing techniques from traditional query processing in distributed environments cannot be directly applied to mobile environments. In this paper, the authors propose techniques for processing mobile queries that address the issue of high memory consumption. A set of walkthrough examples was provided and performances of various techniques were examined. The results show that the technique of first downloading primary keys only from one server and then sending a query to the second server using these primary keys before processing for qualified match in the second server gives the best performance.

This chapter focuses on Mobile GIS (MGIS), which uses wireless networks and small screen mobile devices (such as PDAs and smartphones) to collect or deliver real time, location specific information and services. Such services can be divided into field and consumer (location based services) GIS applications. The use of wireless networks and small screen devices, introduce a series of challenges, not faced by desktop or wired internet GIS applications. This chapter discusses the challenges faced by mobile GIS (e.g. small screen, bandwidth, positioning accuracy, interoperability, etc.) and the various means of overcoming these problems, including the rapid advances in relevant technologies. Despite the challenges, many efficient and effective Mobile GIS applications have been developed, offering a glimpse of the potential market.

This chapter is based on research conducted in cooperation with 12Snap, the leading European mobile marketing company, which has implemented large-scale mobile advertising campaigns with companies such as McDonald’s, Nestlé, Microsoft, Coca-Cola, Adidas, and Sony. To set the overall stage, we first discuss the advantages and disadvantages of the mobile phone in comparison to other marketing media. Then we propose a framework of different types of advertising campaigns that can be supported through the usage of mobile devices. These campaign types include (1) mobile push campaigns, (2) mobile pull campaigns, and (3) mobile dialogue campaigns. Building on this framework, we analyze different campaigns that 12Snap implemented for different consumer goods and media companies. Drawing from these experiences we then discuss a number of key management issues that need to be considered when implementing mobile marketing campaigns. They include the following themes: (1) the choice of campaign type, (2) the design of a campaign, (3) the targeting of the youth market, and (4) the combination of different media types to create integrated campaigns.

Purpose – The purpose of this paper is to get an insight in users’ opinion on library resources/services on small screen mobile devices. Objectives were to establish which types of small screen mobile devices are used and to find out is there a tendency for using academic and educational contents on such devices. Furthermore, aim was to identify whether the users need mobile friendly library web site and services at all. Also, what library resources/services and to what extent respondents consider as the important ones for mobile friendly customization. Finally the results would serve as an orientation in building mobile friendly library web site and services. The author believed that the users were still unaware of the possibility of accessing library web sites and services through mobile devices in general; therefore, this survey also had a role of raising awareness and stimulating their interest. Design/methodology/approach – The survey was focussed on small screen mobile devices with screen size up to seven inches (17.1 cm). Data collection was performed through a questionnaire containing ten questions. The questionnaire was created by LimeSurvey tool, and for mobile optimized version SurveyMonkey.com service was used too. The authors received 295 questionnaires, out of which 285 were taken into account. Findings – The survey found that the largest number of respondents own smartphone/tablet/phablet. The results show that small screen devices are, to some extent, used for educational, academic and informational purposes (reading of e-books and e-journals, education, data checking, internet searching and searching of handy information), but non-academic purposes still predominate (texting, reading e-mails, phone calls, taking pictures). Overall 64 percent of the respondents has expressed need for small screen mobile devices customized library resources/services, but there are 30 percent of undecided respondents. Croatian Scientific Bibliography, e-journals database (EZB), online databases, contact information and lecture halls reservations, has been resources/services requested by respondents to be available in a mobile friendly mode. Originality/value – The survey examines users’ opinion on a new library service before its implementation. Besides giving us a precise insight into the Rudjer Bošković Institute library users’ interest and needs for mobile friendly customization of existing library resource/service, survey gives a unique insight into the correlation of age and gender of the respondents and their answers to the question about having a small screen mobile device and opinion about the customization of library resources and services. To the author’s knowledge, this is the first users’ survey on this topic in Croatia.
