[Termes IGN] voixRésumé : (Auteur) GPS-based pedestrian navigation systems have become increasingly popular. Different interface technologies can be used to communicate/convey route directions to pedestrians. This paper aims to empirically study the influence of different interface technologies on spatial knowledge acquisition in the context of GPS-based pedestrian navigation. A field experiment was implemented to address this concern. Firstly, the suitability of the evaluation methods in assessing spatial knowledge acquisition was analyzed empirically (focusing on the ability of differentiating “familiar“ and “unfamiliar“ participants). The suitable methods were then used to compare the influence of mobile maps, augmented reality, and voice on spatial learning. The field test showed that in terms of spatial knowledge acquisition, the three interface technologies led to comparable results, which were not significantly different from each other. The results bring some challenging issues for consideration when designing mobile pedestrian navigation systems.

[Termes IGN] positionnement par GPSRésumé : (Auteur) GPS is at war. It is a major asset for United States and allied military forces in a number of operating theaters around the world in both declared and undeclared conflicts. But GPS is at war on the domestic front, too at war against a proliferation of jamming equipment being marketed to cause deliberate interference to GPS signals to prevent GPS receivers from computing positions to be locally stored or relayed via tracking networks. There have been many notable examples of deliberate jamming of GPS receivers. Many more likely go undetected each day. In 2009, outages of a Federal Aviation Administration reference receiver at Newark Liberty International Airport close to the New Jersey Turnpike were traced to a $33,200 milliwatt GPS jammer in a truck that passed the airport each day. The driver was reportedly arrested and charged. In July 2010, two truck thieves in Britain were jailed for 16 years. They used GPS jammers to prevent the trucks from being tracked after the thefts. And in Germany, some truck drivers have been using jammers to evade the country's GPS-based road-toll system. The U.S. and some foreign governments have enacted laws to prohibit the importation, marketing, sale or operation of these so-called personal privacy devices. Nevertheless, a certain number of jammers are in the hands of individuals around the world and they continue to be available from manufacturers and suppliers in certain countries. So, GPS jamming is a continuing threat both at home and abroad and a detailed understanding of how the available jammers work is necessary to judge their effectiveness and limitations. This information will also help in developing countermeasures that could be incorporated into GPS receivers to limit the impact of jammers. Jammers constitute an enemy force, and as the Chinese General Sun Tzu stated in the Art of War more than 2,000 years ago, battles will be won by knowing your enemy. [...] In this month's column, a team of researchers from Cornell University and the University of Texas at Austin reports on their analyses of the signal properties of 18 commercially available GPS jammers. The enemy has been exposed.

Data collected by volunteers has long been an important factor in environmental programmes, but the difficulties in applying quality control measures and in ensuring an appropriate sample size of observations for a given area limit their scientific value. This paper addresses this challenge in describing a surveying architecture, allowing efficient in-field data collection from a GPS enabled ubiquitous device. The originality of this architecture comes from a real-time analysis of surveyed responses in order to “drive” the survey for optimised precision and validity. Spatial awareness from the surveying engine allows one to modify the sets of questions for each surveyor volunteer as the survey goes along, and even to try to recruit volunteers in the area. As a result this architecture is able to support the implementation of a dynamic and directed approach to in-field data collection with real-time quality control driven by an adaptive surveying modelling technique insuring optimised data collection and personalised feedback to users. A plug-in architecture gives the possibility to extend using RSS, Twitter and Mappiness data sources, with other real time feeds, then allowing the adaptive surveying engine to use multilevel multi-sourced sets of information. The paper describes this conceptual architecture and a technical solution for its implementation, independent of the mobile hardware producer, tablets, smart phones, netbooks, laptops, in order to allow the widest public participation opportunity possible. The implementation was tested on Google Android and Apple iPhone devices with a use case coming from the Tranquillity Report of the Campaign to Protect Rural England (CPRE).
