Disaster Prevention and Mitigation (DPM) is aimed to help people to prevent and reduce property damage in time. In this paper, we propose a DPM system called Gaia, which collects sensed data, and sends them to a back-end DPM Server with improved performance. Gaia is equipped with double 3G interfaces and Load Balancing mechanisms with Round Robin scheduling to ensure stable transmission. Furthermore...
The working of the GPS requires a clear line of sight for accurate services. However this is a drawback when the vehicle is stuck in a long tunnel or a place where the GPS data is unavailable. In this paper we propose the TLST: Time of Arrival Based Localization and Smart Tunnels in VANETs. The paper focuses on the time of arrival and time difference of arrival based localization in the vehicular...
This paper presents the architecture of an extended area monitoring system based on crowdsourcing and mobile devices. In particular areas (as very large historical sites) it can be difficult or impossible to install fixed cameras due to the huge number of candidate points of interest (POI) to monitoring or to the significant impact on site (i.e. cameras or other sensors could be too invasive towards...
The paper reports the proof-of-concept tests, i.e. ergonomic, non-mobility tests with participation of blind volunteers and emphatic field trials (i.e. with the participation of sighted individuals) of a teleassistance system for the visually impaired. The system consists of two terminals connected by the GSM and Internet networks. The mobile terminal, housing a digital camera, GPS receiver and headset,...
Citizens of any country face civic problems in their day to day lives. They resort to the one of the several ways provided by the government to file their complaints. With advancements in technology, the complaint registration systems have evolved in different ways to simplify the task of registering as well as addressing the complaints. This research paper presents the architecture of a GPS based...
Road Traffic congestion is a perennial problem across the globe. The nature of the problems associated with vehicular traffic is not uniform across the globe. In the recent past, several solutions were proposed to improve traffic management. However most of these solutions cater to the traffic scenarios in the developed countries where traffic is lane based and the issues being encountered is quite...
The widespread use of smartphones has prompted the provision of a variety of services that exploit sensors installed in the smartphones, such as GPS, and augmented reality (AR). This paper proposes a method in which a user of such a smart terminal receives a message from a person passing by, and has the message displayed alongside the image of that person on the screen of the camera installed in the...
In this article a multichannel information system to build and deliver rich user experiences in exhibits and museums is presented. The system was designed to use information about a particular exhibit or museum while delivering a wide user experience based on different distribution channels. The overall information is used to build different solutions that can be delivered simultaneously on different...
The approach and rationale used to create controlled data sets encompassing video, track, and reference data and meta-data is described in this paper. The data sets are designed to support the development of automated technologies for the detection of situational and operational behaviors of interest. A custom tool for the concurrent visualization and access of the data is also introduced.
An increasing number of new geolocation services are exploiting the new capabilities of smartphones, most of which incorporate GPS location. There are fewer applications for providing indoor location, partly due to the cost of the required infrastructure. In this paper, we present QR-Maps, a simple and efficient tool that can be used in smartphones to obtain accurate indoor user locations. This tool...
The integration of communication technologies such as radio frequency identification (RFID), global positioning system (GPS), general packet radio system (GPRS), geographic information system (GIS) with a camera are constructed for solid waste monitoring system. The aim is to improve the way of responding to customer's inquiry and emergency cases and estimate the solid waste amount without any involvement...
This paper presents the use of Augmented Reality technics exploiting distributed geographical information in a mobile device using wireless network. Our system offers useful informations (number of parcel, name of the owner, agronomic structure, juridical state, and adequate plant) related to each parcel geo-referenced according to the user's position and orientation. We used inertial sensor MTi and...
Geotagging, in which digital photos are labelled with the location where they were taken, becomes more popular today. Users can browse the photos on digital map and make the Web photo sharing and management even more conveniently. However, lacking the function of authentication and the way to deal with the situation that information within the EXIF area being falsified, the content of the photo might...
This paper represents the framework which offers the user friendly data collection of the multi-modal information that consists of image, location data and texts, and secondary use of them. A local area information map creation system, for disaster prevention or crime prevention, is shown as an application of the suggested framework. Users collect the image data where people need attention together...
Applications with geo-tagged photos have drawn lots of attentions in recent years. However, most previous works consider the GPS information of each photo individually to improve the metadata of the corresponding photo. In this paper, we leverage GPS data in a series of scenic photos and propose the personalized scenic itinerary recommendation system. Our system provides personalized suggestion of...
