II Congreso Virtual Internacional de Educación, Innovación y TIC – EDUNOVATIC 2017

María Vega López González, Ana García-Varcáncel Muñoz-Repiso, Marta Martín del Pozo, Verónica Basilotta Gómez-Pablos, Carlos Alberto Catalina Ortega. “Serious games evaluation and analysis metrics: Contribution for eConfidence project”. II Congreso Virtual Internacional de Educación, Innovación y TIC. 12-14 diciembre, 2107. Madrid, España

When we talk about Serious Games, we refer to games whose main goal goes beyond pure entertainment in order to research the area of education and training. In this line, eConfidence Project is carried out: a project funded by the European Union’s Horizon 2020 research and innovation program under the grant agreement No 732420. Its purpose is analyzing the benefits which could be obtained through the use of Serious Games to change teenager
student’s behaviour and attitudes related to bullying and safe use of Internet.
To know the quality of this kind of these kinds of games and estimate their effect on behaviour changes, we need specific and concrete analysis indicators, called metrics. Software designers and educators work together on the definition of these parameters with two primary purposes: decide whether or not they will be able to provide the information needed to achieve the stated goals, and assure the consumer retention and monetization for the
software design company.

EAI International Conference on IoT Technologies for HealthCare

Simulator of behavioural aspects for safer transport

Mobyen Uddin Ahmed, Shahina Begum, Carlos Alberto Catalina, Lior Limonad, Bertil Hök, Gianluca Di Flumeri. “Cloud-based Data Analytics on Human Factor Measurement to Improve Safer Transport”. In 4th EAI International Conference on IoT Technologies for HealthCare October 24–25, 2017. Angers, France, At Angers, France. Projects

Abstract: Road transport is known to be the most dangerous of all transport modes and poses a major societal challenge for EU. It has been claimed that 90% of road-traffic crashes are caused by driver error, being unsafe behaviour a significant factor in traffic accidents. Improving road safety means understanding the individual and collective behaviour of actors involved (drivers, two wheelers, pedestrians) and their interaction between themselves and safety-related systems and services. The goal of SIMUSAFE (SIMUlator of Behavioural Aspects for SAFEr Transport) following the FESTA-V model methodology is to develop realistic multi-agent behavioural models in a transit environment where researchers will be able to monitor and introduce changes in every aspect , gathering data not available in real world conditions.
Driving simulators of several vehicles (cars, motorcycles, bicycles) and Virtual Reality (for pedestrians) will be used to simulate test environments. This will also enable the evaluation of scenarios which are not possible even with naturalistic driving (dangerous conditions, multiple monitored actors in the same scene, under influence of substances). Data collected from simulations will be correlated with naturalistic driving tests, such that the simulation and model aspects are the closest possible to real world data. From the developed model and collected data, impacting factors causing an event (crash, nearcollision, infractions) from the environment and road users will be identified and quantified. Such knowledge will be the base for the development of more effective and pro-active measures for the prevention and mitigation of such factors, with subsequent impact in the safety devices market, regulations and driver education.

International Conference on Computer Vision Theory and Applications – 2016

Saracchini, Rafael FV, Carlos A. Catalina, R. Minetto, J Stolfi. “VOPT: Robust Visual Odometry by Simultaneous Feature Matching and Camera Calibration”, – In Proceedings of the International Conference on Computer Vision Theory and Applications, (2016)

Abstract: In this paper we describe VOPT, a robust algorithm for visual odometry. It tracks features of the environment with known position in space, which can be acquired through monocular or RGBD SLAM mapping algorithms. The main idea of VOPT is to jointly optimize the matching of feature projections on successive frames, the camera’s extrinsic matrix, the photometric correction parameters, and the weight of each feature at the same time, by a multi-scale iterative procedure. VOPT uses GPU acceleration to achieve real-time performance, and includes robust procedures for automatic initialization and recovery, without user intervention. Our tests show that VOPT outperforms the PTAMM algorithm in challenging videos available publicly.

Helena C. G. Leitao, Rafael F. V. Saracchini, Jorge Stolfi. “Geometric Encoding, Filtering, and Visualization of Genomic Sequences”

Abstract: This article describes a three-channel encoding of nucleotide sequences, and proper formulas for filtering and downsampling such encoded sequences for multi-scale signal analysis. With proper interpolation, the encoded sequences can be visualized as curves in three-dimensional space. The filtering uses Gaussian-like smoothing kernels, chosen so that all levels of the multi-scale pyramid (except the original curve) are practically free from aliasing artifacts and have the same degree of smoothing. With these precautions, the overall shape of the space curve is robust under small changes in the DNA sequence, such as single-point mutations, insertions, deletions, and shifts.

Keywords: bio-sequences analysis, signals analysis, filtering, multi-scale

International Conference on Computer Vision and Graphics ICCVG 2014

Rafael F. V. Saracchini, Carlos C. Ortega. “An Easy to Use Mobile Augmented Reality Platform for Assisted Living Using Pico-projectors”

Abstract: We present in this paper an easy to use Computer Vision based platform for real-time 3D mapping, and augmented reality in indoors environments and its innovative application in Assisted Living. The information is displayed to the user by projecting it into the environment by a wearable device with embedded pico-projector. The system does not need markers or complicated set-ups, using low cost off-the-shelf equipment. It is also robust to small changes of the environment, and can make use of surrounding objects to provide more stable camera tracking. Pilot tests in health care centres and residences demonstrated the efficacy of the initial prototype.

Catalina Ortega, C.A. “IDE para creación de manuales con Realidad Aumentada para PC y PDA” JOREVIR 2009: Third conference on Virtual Reality and Virtual Environments

Abstract: En el presente artículo se mostrará el desarrollo de un editor de manuales interactivos mediante realidad aumentada (ECRAM). Los manuales interactivos son una de las aplicaciones más interesantes que sepueden desarrollar con esta tecnología, sin embargo tienen varios problemas a la hora de su aplicación en entornos industriales. En el presente proyecto se pretende disminuir el impacto de dos de ellos: la necesidad de expertos programadores para poder crear un manual de operaciones y la cantidad de tiempo necesario para crearlos. Como solución a este problema ITCL ha desarrollado una primera versión de un editor de operaciones que, de forma fácil y sin necesidad de conocimientos específicos, permite crear los pasos para realizar una operación y poder visualizarla en un PC o una PDA.
Keywords: realidad aumentada, mantenimiento, prevención, formación, motor gráfico, 3D.

Catalina Ortega C.A. “Simulador de carretillas elevadoras” JOREVIR 2009: Third conference on Virtual Reality and Virtual Environments

Abstract: Las carretillas elevadoras son uno de los elementos que más accidentes provocan en los entornos industriales. Una de las herramientas para paliar los efectos de estos accidentes así como disminuir su número, consiste en proporcionar una mejor formación a los operarios que emplearan estas máquinas. Para ello se ha creado un simulador de carretillas completo con una cabina de una carretilla real sensorizada que es manejada por el operario a formar, este visualiza el entorno gracias a un casco de realidad virtual y un sensor de seguimiento de cabeza.
