Every year, for ten years now, the IPIN competition has aimed at evaluating real-world indoor localisation systems by testing them in a realistic environment, with movement, using EvAAL framework. The provided unique overview of state-of-the-art systems, technologies, and methods positioning navigation purposes. Through fair comparison performance achieved each system, was able to identify most promising approaches pinpoint critical working conditions. In 2020, included 5 diverse off-site...
The Indoor Positioning and Navigation (IPIN) conference holds an annual competition in which indoor localization systems from different research groups worldwide are evaluated empirically. objective of this is to establish a systematic evaluation methodology with rigorous metrics both for real-time (on-site) post-processing (off-site) situations, realistic environment unfamiliar the prototype developers. For IPIN 2018 conference, was held on September 22nd, 2018, Atlantis, large shopping...
The development of indoor positioning solutions using smartphones is a growing activity with an enormous potential for everyday life and professional applications. research activities on this topic concentrate the new that are tested in specific environments under their own evaluation metrics. To explore real quality smartphone-based capabilities seamlessly adapting to different scenarios, it needed find fair frameworks. design competitions extensive pre-recorded datasets valid way generate...
IPIN 2019 Competition, sixth in a series of competitions, was held at the CNR Research Area Pisa (IT), integrated into program Conference. It included two on-site real-time Tracks and three off-site Tracks. The four presented this paper were set same environment, made buildings close together for total usable area 1000 m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> outdoors 6000 indoors over floors, with path length exceeding 500 m....
Indoor positioning is a thriving research area which slowly gaining market momentum. Its applications are mostly customised, ad hoc installations; ubiquitous analogous to GNSS for outdoors not available because of the lack generic platforms, widely accepted standards and interoperability protocols. In this context, Positioning Navigation (IPIN) competition only long-term, technically sound initiative monitor state art real systems by measuring their performance in realistic environment. Most...

For outdoors, Global Network Navigation Systems have become the standard mechanism of positioning; but for indoor environments, there is still no system. Several mechanisms been proposed and, among them, some more extended are those that use Wi-Fi signal positioning, and mainly, known as fingerprinting. However, actual depends on environmental conditions: instability Wi-Fi, differences in sensors Smartphones, etc. One these uncontrolled effects interaction between RF human bodies. Human...
Background: Chronic neck and low back pain are very common have detrimental effects for people society. In this study, we explore the experiences of individuals with and/or using a written narrative methodology. Materials & methods: A total 92 explained their experience narratives. Narratives were analyzed through thematic analysis text data mining. Results: Participants wrote about in terms characteristics, diagnosis process, consequences, coping strategies, triggers, well-being future...
Health professionals and authorities strive to cope with heterogeneous data, services, statistical models support decision making on public health. Sophisticated analysis distributed processing capabilities over geocoded epidemiological data are seen as driving factors speed up control in these health risk situations. In this context, recent Web technologies standards-based web services deployed geospatial information infrastructures have rapidly become an efficient way access, share,...
With the adoption of indoor positioning solutions, which enable for a variety location-based spatial services, number map standards and formats have been proposed in last decade. As each these standard has its own purpose, strengths weaknesses are necessary to be understood analyzed before selecting one them given application. The Indoor Map Subcommittee established under IPIN/ISC 2017. Among others, goal this working group is compare available standards, provide guideline their application...
Advances in the development of information and communication technologies have facilitated social interrelationships, but also sexual contacts without appropriate preventive measures. In this paper, we will focus on situations which people use applications to meet partners nearby, could increase their chance exposure sexually transmitted infections (STI). How can encourage users adopt measures violating privacy or infringing character application? To achieve goal preventing STI, used design...
Background Advances in the development of information and communication technologies have facilitated social sexual interrelationships, thanks to websites apps created this end. However, these resources can also encourage contacts without appropriate preventive measures relation HIV other sexually transmitted infections (STIs). How users be helped benefit from advantages while keeping mind those measures? Objective This study aimed prevent STIs by helping remember risky situations. Methods...
Purpose The prevalence of pregnancy and sexually transmitted infections among adolescents in low middle-income countries leads us to believe that sexual reproductive health (SRH) information needs are still unmet. This paper investigates current sources their limitations then explores the role technology could play. Methods: In an exploratory qualitative study themes identified; (1) preferred SRH information; (2) limitations; (3) meeting needs. Results: Mobile phone-based apps improve...
Adolescents transitioning from childhood to adulthood need be equipped with sexual reproductive health (SRH) knowledge, skills, attitudes, and values that empower them. Accessible, reliable, appropriate, friendly information can provided through mobile phone-based interventions.
Indoor positioning systems usually consider the average error over a set of evaluation samples, or quartile that value, as global error. However, they do not provide metric for uncertainty each individual position estimation.

Abstract Videos created with the hands of teachers filmed have been perceived as useful educational resource for students Physics in undergraduate courses. In previous works, we analyzed students’ perception about videos by asking them their experiences. this work, analyze same facts, but from a learning analytics perspective, analyzing interactions that during experience. With analysis, obtain how behave and may compare whether behavior aligns perceptions obtained research. The data work...
The research presented in this paper is focused on In-home positioning systems. These indoor environments are characterized by a reduced number of AP, narrow spaces and very important radio signal attenuation. Existing techniques seems to be not totally suitable for these scenarios; proposes an add-on helping the use wearable ultrasound sensors (distance measurements). One step using RF signals off-line phase generation Radio Maps. In order considerably reduce time needed phase, uses...
