Ringing the changes in mobile services

The development of task-aware location-based services for mobile devices could create new opportunities for businesses.
Ringing the changes in mobile services
Mobile services have expanded exponentially in the past few years, with increasingly sophisticated handsets and the widespread adoption of wireless networks. Despite this, however, the mobile service market is still dominated by simple infotainment services.

This is especially apparent in the area of location-based systems (LBS), which have not proved as successful as was first predicted. This is partly because the content offered in typical LBS applications remains narrow and static, and mobile users still require a GPS module to utilise mobile LBS.

The EU-funded 'Task-aware-location-based services for mobile environments' (TALOS) project sought to address these issues. It also aimed to create new opportunities for European small and medium-sized enterprises (SMEs) in the mobile services sector by delivering commercially successful location-based services for mobile environments.

Project members set out to provide the technological foundations needed to achieve this goal. A context aggregation module was implemented, which captures the user's contextual attributes. An iPhone-compatible soft-GPS wireless positioning component is able to estimate the user's current position both indoors and outdoors without requiring specialised hardware.

A user interface, based on the principles of task computing, was also developed to provide an efficient content discovery channel for mobile users. The interface was based on the results of surveys involving both expert and non-expert users. To allow for the efficient manipulation of content, a content repository was developed. A web-based content manipulation interface for the repository provides the basic means for any content manipulation.

All these components were combined to create the TALOS system. The first prototype is a portal that allows travellers to buy or select a MMV travel guide of their choice. A second prototype consists of a mobile travel guide for the iPhone platform.

The aim of TALOS was to make LBS more user friendly by structuring content around specific tasks. The technology should interest innovative SMEs in numerous sectors as it can be used for a wide range of applications and potential exploitation targets.
