Location-Based Services: Back to the Future (original) (raw)

Location based services: ongoing evolution and research agenda

Journal of Location Based Services

We are now living in a mobile information era, which is fundamentally changing science and society. Location Based Services (LBS), which deliver information depending on the location of the (mobile) device and user, play a key role in this mobile information era. This article first reviews the ongoing evolution and research trends of the scientific field of LBS in the past years. To motivate further LBS research and stimulate collective efforts, this article then presents a series of key research challenges that are essential to advance the development of LBS, setting a research agenda for LBS to 'positively' shape the future of our mobile information society. These research challenges cover issues related to the core of LBS development (e.g. positioning, modelling, and communication), evaluation, and analysis of LBS-generated data, as well as social, ethical, and behavioural issues that rise as LBS enter into people's daily lives.

A critical evaluation of location based services and their potential

Journal of Location Based Services, 2007

This Editorial lead paper for the Journal of Location Based Services surveys this complex and multi-disciplinary field and identifies the key research issues. Although this field has produced early commercial disappointments, the inevitability that pervasive location-aware services on mobile devices will emerge means that much research is needed to inform these developments. The paper reviews firstly: the science and technology of positioning, geographic information science, mobile cartography, spatial cognition and interfaces, information science, ubiquitous computing; and secondly the business, content and legal, social and ethics aspects, before synthesising the key issues for this new field.

Location-Based Services: a vehicle for IT&T convergence

Location-based services (LBS), more than any other mobile commerce application area has served to bring together information technology and telecommunications (IT&T) industries. While much has been written on the potential of LBS, literature on how it is a catalyst for digital convergence is scant. This paper identifies and explores the various levels of converging technologies in mobile commerce by using three LBS case studies. Through literal replication the findings indicate that IT&T technologies are converging at the infrastructure, appliance and application level. It is predicted that mCommerce applications will increasingly rely on industry convergence to achieve their desired outcomes.

Real Life Applications and Implementation of Potential Location Based Services

The need to know 'where' has become essential. Location Based Services add real world structure to the fixed and wireless internet through dynamically linking content to location. Right from finding your way through traffic, to checking out for the nearest medical store as you are driving, LBS is expected to help you all the way. This paper gives an overview of what location-based services have to offer, and a real-life situation showing how the technology can be applied and implemented as well. Taking advantage of these services can save time and aggravation in our increasingly wireless world.

Humancentric applications of precise location based services

2005

Mobile technologies, which allow users to move around while maintaining the ability to access a network and its services, now claim a significant degree of attention in both industry and academia. In this vision, one particular attribute gains critical importance: location. The ability to pinpoint a mobile user's location creates a new class of applications and services. These location based services (LBS) exploit the known location of a user to provide services dependent on their geographic context and personalised needs. However, as newer positioning technologies are introduced into the market with a greater level of location accuracy, and existing technologies are integrated to overcome limitations, issues pertaining to the use and potential misuse of location information rise to the fore. In addition to this, perhaps because LBS are so new, there has been limited investigation into exactly what effects the widespread use of these technologies may have. This thesis aims to rectify a gap in current knowledge by presenting a plausible scenario that describes how humancentric applications of LBS could change the world of tomorrow, based on the current state of development. It also makes several original contributions in an analysis of legal, ethical, social and technological issues that arise from the scenario.

Interface Design of Location-Based Services

Advances in Human-Computer Interaction 416 2. Literature Review 2.1 Local based service (LBS) Mobile location-based commerce refers to the provision of location-based information on mobile devices as a result of a user request (Varshney, 2003). It aims to provide specific targeted information to users based on each specific user's location at any time (Benson, 2001). OGC (2003) stated that LBS is defined as a wireless-IP service that uses geographic information to serve a mobile user, or as any application service that takes advantage of the position of a mobile device. The LBS applications include emergency and safety-related services, entertainment, navigation, directory and city guides, traffic updates, and location-specific advertising and promotion in addition to site-based purchasing with e-wallet enabled wireless devices. These services can answer questions such as, "Where can I find a Chinese restaurant," or "Where are my nearest friends?". For example, NTT DoCoMo expresses a "friend finder" service on its iMode system (Levijoki, 2000). Users can predefine which friends are allowed to know their location. Integrating the map database with the PoI database can create detailed, available digital representation of the road network and business services. To cover simple city maps, routings, business finder, etc., these services are usually combined with a digital map associated to the user location. Reichenbacher (2001) shows that LBS applications typically use information from several content databases: • Road network (digital maps).

Location-based services: technical and business issues

GPS Solutions, 2002

Geographical Information System (GIS) and Global Positioning System (GPS) technologies are expanding their traditional applications to embrace a stream of consumer-focused, location-based applications. Through an integration with handheld devices capable of wireless communication and mobile computing, a wide range of what might be generically referred to as "Location-Based Services" (LBS) may be offered to mobile users.
