Abstract

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 realistic movement, using the EvAAL framework. The competition provided a unique overview of the state-of-the-art of systems, technologies, and methods for indoor positioning and navigation purposes. Through fair comparison of the performance achieved by each system, the competition was able to identify the most promising approaches and to pinpoint the most critical working conditions. In 2020, the competition included 5 diverse off-site off-site Tracks, each resembling real use cases and challenges for indoor positioning. The results in terms of participation and accuracy of the proposed systems have been encouraging. The best performing competitors obtained a third quartile of error of 1 m for the Smartphone Track and 0.5 m for the Foot-mounted IMU Track. While not running on physical systems, but only as algorithms, these results represent impressive achievements.

Abstract

IPIN 2019 Competition, sixth in a series of IPIN competitions, was held at the CNR Research Area of Pisa (IT), integrated into the program of the IPIN 2019 Conference. It included two on-site real-time Tracks and three off-site Tracks. The four Tracks presented in this paper were set in the same environment, made of two buildings close together for a total usable area of 1000 m2 outdoors and and 6000 m2 indoors over three floors, with a total path length exceeding 500 m. IPIN competitions, based on the EvAAL framework, have aimed at comparing the accuracy performance of personal positioning systems in fair and realistic conditions: past editions of the competition were carried in big conference settings, university campuses and a shopping mall. Positioning accuracy is computed while the person carrying the system under test walks at normal walking speed, uses lifts and goes up and down stairs or briefly stops at given points. Results presented here are a showcase of state-of-the-art systems tested side by side in real-world settings as part of the on-site real-time competition Tracks. Results for off-site Tracks allow a detailed and reproducible comparison of the most recent positioning and tracking algorithms in the same environment as the on-site Tracks.

Abstract

The Indoor Positioning and Indoor Navigation (IPIN) conference holds an annual competition in which indoor localization systems from different research groups worldwide are evaluated empirically. The objective of this competition is to establish a systematic evaluation methodology with rigorous metrics both for real-time (on-site) and post-processing (off-site) situations, in a realistic environment unfamiliar to the prototype developers. For the IPIN 2018 conference, this competition was held on September 22nd, 2018, in Atlantis, a large shopping mall in Nantes (France). Four competition tracks (two on-site and two off-site) were designed. They consisted of several 1 km routes traversing several floors of the mall. Along these paths, 180 points were topographically surveyed with a 10 cm accuracy, to serve as ground truth landmarks, combining theodolite measurements, differential global navigation satellite system (GNSS) and 3D scanner systems. 34 teams effectively competed. The accuracy score corresponds to the third quartile (75 th percentile) of an error metric that combines the horizontal positioning error and the floor detection. The best results for the on-site tracks showed an accuracy score of 11.70 m (Track 1) and 5.50 m (Track 2), while the best results for the off-site tracks showed an accuracy score of 0.90 m (Track 3) and 1.30 m (Track 4). These results showed that it is possible to obtain high accuracy indoor positioning solutions in large, realistic environments using wearable light-weight sensors without deploying any beacon. This paper describes the organization work of the tracks, analyzes the methodology used to quantify the results, reviews the lessons learned from the competition and discusses its future.

Abstract

Los videos digitales tienen una presencia importante y creciente en los procesos de aprendizaje. Sin embargo, la creación de videos es una actividad compleja que consume mucho tiempo a los profesores. Por tanto, es importante analizar qué coste tiene crear videos en distintos formatos y qué utilidad tiene cada uno de ellos para el estudiante. Con ese objetivo, el trabajo presentado analiza el coste de creación y la utilidad de lo que denominamos “Videos con las manos” y se compara con otros tipos de videos (grabación de escritorio y grabación con un bolígrafo de tipo LiveScribe®). Las pruebas se han realizado con alrededor de 100 videos de distintos tipos en distintas asignaturas durante 2016.

Abstract

Los videos digitales tienen una presencia importante y creciente en los procesos de aprendizaje. Sin embargo, la creación de videos es una actividad compleja que consume mucho tiempo a los profesores. Por tanto, es importante analizar qué coste tiene crear videos en distintos formatos y qué utilidad tiene cada uno de ellos para el estudiante. Con ese objetivo, el trabajo presentado analiza el coste de creación y la utilidad de lo que denominamos “Videos con las manos” y se compara con otros tipos de videos (grabación de escritorio y grabación con un bolígrafo de tipo LiveScribe®). Las pruebas se han realizado con alrededor de 100 videos de distintos tipos en distintas asignaturas durante 2016. La metodología utilizada para analizar la dificultad en la creación de los distintos tipos de videos y su utilidad para los estudiantes es mixta, cualitativa y cuantitativa.

Abstract

The development of indoor positioning solutions using smartphones is a growing activity with an enormous potential for everyday life and professional applications. The research activities on this topic concentrate on the development of new positioning solutions that are tested in specific environments under their own evaluation metrics. To explore the real positioning quality of smartphone-based solutions and their capabilities for seamlessly adapting to different scenarios, it is needed to find fair evaluation frameworks. The design of competitions using extensive pre-recorded datasets is a valid way to generate open data for comparing the different solutions created by research teams. In this paper, we discuss the details of the 2017 IPIN indoor localization competition, the different datasets created, the teams participating in the event, and the results they obtained. We compare these results with other competition-based approaches (Microsoft and Perf-loc) and on-line evaluation web sites. The lessons learned by organising these competitions and the benefits for the community are addressed along the paper. Our analysis paves the way for future developments on the standardization of evaluations and for creating a widely-adopted benchmark strategy for researchers and companies in the field.

9. Idiosincrasia de los PFC en la UOC

Author

Rius, Àngels, Pérez-Navarro, Antoni, Rius, Àngels, and Pérez-Navarro, Antoni

Abstract

En este artículo se introducen las características de los proyectos finales de carrera (PFC) en la Universidad Oberta de Catalunya (UOC), en los que se simula el desarrollo de un proyecto en el mundo empresarial. Para ello se empieza introduciendo las distintas figuras que llevan a cabo la acción docente en la UOC, sus roles y la forma como se complementan entre sí. A continuación se explican las limitaciones y elementos que distinguen los PFC de la UOC de los de la universidad presencial y cómo se estructuran, mostrando su paralelismo con los proyectos empresariales. También se ponen de manifiesto los problemas con los que se enfrenta la UOC a la hora de poner en práctica estos PFC, y las actuaciones emprendidas para poner remedio a estas limitaciones. Finalmente, se recogen las conclusiones del trabajo en las que se refleja que, si bien los PFC planteados como proyectos de empresa son fundamentales para los estudiantes, sería aconsejable extender esta forma de trabajar a todas las universidades, ya que en el caso de la UOC, muchos estudiantes son ya profesionales integrados en el mundo empresarial.
