Item A "context evaluator" model for a multimodal user interface in driving activity(2011) Murgoitio, Jesús; Urquiza, Arkaitz; Larburu, Maider; Sánchez, Javier; CCAM; ROBOTICA_FLEX; POWERTRAIN; Tecnalia Research & InnovationFocused on new HMI for vehicles, this paper explains the methodology followed by Tecnalia to provide an evaluation of the context, based on sensors data, in order to achieve the optimum usability and ubiquity levels at any given moment, and finally to optimize the driving task from the safety point of view. The paper is divided into three sections. Firstly, there is an introduction in which the main concepts, multimodality and Ambient intelligence, are explained (section 1), and this is followed by the two projects related to the work shown here (section 2). In section 3 we will go on to describe the methodology used to obtain an evaluation of the context, as is necessary for a car HMI with multimodal capabilities. Finally, a particular "Context evaluator" is displayed in order to illustrate the methodology and report the work carried out.Item Safe road trains for the environment (SARTRE): Validation of SARTRE Platoon service and the SARTRE HMI(2012) Larburu, Maider; Urquiza, Arkaitz; Sanchez, Javier; POWERTRAIN; ROBOTICA_FLEX; Tecnalia Research & InnovationEver since the electronically coupled vehicles concept was introduced in 1998, besides the increased reliability and reduced cost of electronics and communications, it is now feasible to develop a safe and reliable platooning system, which includes specific Human-Machine Interface (HMI) for platoon vehicles. However, the development of new and sophisticated in-vehicle systems fostered by technical innovation demands careful validation of these systems. Whereas excellent system performance may be sufficient for the technician, it is as important that the equipment is appealing and accepted by the driver. It is unproductive to invest effort in designing and building a driving support system if the system is never switched on, or even disabled. Consequently, the aim of this study is to validate the acceptance of the SARTE platoon service and the developed HMI for a platooning environment within the European project SARTRE [1]. Taking into account potential end-users point of view, was evaluated the following indicators: usefulness, satisfying level, understanding level, ease of use, perceived safety and workload, by means of an Acceptance Scale questionnaire, Technological Acceptance Model questionnaire, etc., in order to collect the self-reported data after platoon driving tests. This was allowed thanks to this study was conducted in a driving simulator, under virtual environment.Item Spanish Initiative for Fully Automated Stowage on Roll-on/roll-off Operations(2016) Murgoitio, Jesus; Vazquez, Fernando; Samaniego, Ricardo; Paz, Enrique; Sachocos, Miguel; Arejita, Beñat; Urquiza, Arkaitz; Veiga, Eusebio; CCAM; ROBOTICA_FLEXIn the past decades, social development has motivated a notable growth on transportation necessities. In 2020, higher tendencies are expected, so transportation demand will grow about a 20%. Besides, one of the foundations of the UE's Green Policy initiative for freight is the transportation sea-to-ground through the so-called “Short sea shipping” or “Motorways of the sea”. Facing this scenario, it is needed the development of technologies and solutions which contribute to raise the profitability, flexibility and efficiency of marine transportation. This will lead to more competitive freight, so investing on such technologies is a guarantee of success. On this basis, within the framework of the Innterconecta 2013 programme, funded by the Spanish Ministry of Economy and Competitiveness through the Centre for Industrial Technological Development (CDTI), the project AUTOPORT is being developed, which objectives are here detailed. The main objective of the project is to develop the technologies needed for a fully automated stowage on roll-on/roll-off ships in order to improve the logistic flow, reduce stowage times and maximize the efficiency of the space occupation in hold. This will be accomplished by both the automation of logistic processes and terminal trucks. Automation of processes aims for obtaining a stowage plan which reduces to the minimum the obstructions between cargo and trucks in the process and also the imbalance of the hold, in order to allow easy and smooth load operations even in rough sea conditions. Automation of terminal trucks consist in the efficient use of localization, path planning and control for taking a specifically designated roll trailer and stowing it on the exact hold location pointed by the stowage plan, all without human intervention.
