[en] The arrival of the new era of Industry 4.0 at the beginning of the 2010 decade has significantly changed the landscape of industrial reality. This new paradigm includes new technologies such as cyberphysical systems, the Internet of Things, Big Data and Cloud Computing in manufacturing processes. These intelligent systems are capable of collecting, storing and studying data to offer new products and services that optimize production processes and exploit the full potential of this new industry. In this context, operators will begin to acquire more strategic, decision-making and problem-solving functions, evolving towards the concept of Operator 4.0. To this end, working environments and especially industrial interfaces will have to be adapted to the needs and characteristics of the operators, so that they can use the information obtained from the new technologies to make the most of their strengths and capabilities. Given this situation, user experience (UX) is presented as one of the disciplines that shows the greatest potential in the design and evaluation of industrial interfaces (Laschke et al., 2020). Beyond the pragmatic aspects that seek the efficiency of task execution, UX focuses on designing interactions that meet the emotional needs of people (Hassenzahl, 2010). In fact, industrial systems designed based on the UX perspective, in addition to increasing the efficiency of operators, will generate positive emotions that impact on their motivation and involvement, increasing intelligence, decision-making capacity and facilitating learning processes (Kaasinen et al., 2019). In order to facilitate the introduction of UX design and evaluation aspects of industrial interfaces in manufacturing companies, this doctoral thesis describes the development of the DEMOX model (Design and Evaluation for Machine-Operator eXperiences). The model presents a working procedure that allows the evaluation of the current experience of operators with industrial interfaces and enables the proposal of new solutions. To this end, it proposes a user centered evaluation method called eXperience Capturer (XC) and the expert evaluation tool HEMEI. In this way, it offers a working model for creating new interface solutions that allow operators to acquire the new roles of Operator 4.0, creating interactions that, on the one hand, increase their efficiency and performance in the execution of tasks and, on the other hand, increase their psychological well-being at work. In this research, the process for the development of the DEMOX model is shown. In the first chapter, once the subject has been contextualized, the objectives and hypotheses of the investigation are listed, along with the methodology applied. In the second chapter, the literature review is conducted in the field of UX evaluation and specifically in the industrial context. The third chapter describes the XC evaluation method, together with the MHLAB I case study developed for its validation. The fourth chapter shows the HEMEI tool, with the description of its aspects and the MHLAB II case study executed for its validation. The fifth chapter presents the DEMOX working model, which describes a design and evaluation procedure for industrial interfaces composed of the methods described above. Two case studies, MHLAB III and MHLAB IV, are shown for validation. Finally, the main conclusions of the doctoral thesis are presented and proposals for future lines of research are described. Therefore, these are the most relevant contributions obtained in the present doctoral thesis:  New procedure for the design and development of digital interfaces, called User Centered Agile Design (UCAD).  New classification table of UX evaluation methods and tools.  The eXperience Capturer (XC), a new method for evaluating UX in the interaction with industrial interfaces, taking into account pragmatic and experiential aspects in the three phases of the interaction, with a multi-method approach that combines quantitative, qualitative and monitoring tools.  HEMEI: new tool for the expert evaluation of UX in industrial interfaces, evaluating both the pragmatic and experiential aspects of the interaction.  DEMOX model, a new procedure for the evaluation and design of UX in industrial interfaces, to facilitate the integration of such knowledge into the current processes of manufacturing companies.

[eu] 2010-eko hamarkada hasieran heldu zen Industrial 4.0 fenomenoak egungo industriaren ikuspegia guztiz aldatu du. Laugarren iraultza industrial honek, fabrikazio prozesuetan sistema ziber-fisikoak, interneta, Big Data edota Cloud Computing teknologiak txertatzea ahalbidetu du. Teknologia adimentsu hauei esker, lantegietako sistema konektatu guztien datuak jaso, gorde eta ikertu daitezke, honela balio gehitua duten produktu eta zerbitzu berriak eskainiz. Aro berri honetan langileak eginkizun estrategiko berriak bereganatzen hasiko dira, Operator 4.0 kontzepturantz bilakaera eginez. Horretarako, lan inguruneak eta batez ere teknologia hauekin interaktuatzeko interfazeak langileen behar eta ezaugarrietara egokitu beharko dira. Honen ondorioz, langileek teknologia berri hauek dakarten gaitasuna guztiz aprobetxatzea bermatuko da. Egoera honen aurrean, erabiltzailearen esperientzian oinarritutako diseinu disziplina, UX deiturikoa, erabiltzaileen beharretara egokitutako interfazeak diseinatu eta ebaluatzeko aukera gehien eskaintzen duen disziplina konsidera daiteke (Laschke et al., 2020). UX-a, lanen efizientzia bilatzen duten aspektu pragmatikoaz haratago, erabiltzaileen behar emozionalak betetzen dituzten interakzio esperientziak diseinatzean oinarritzen da (Hassenzahl, 2010). Izan ere, UX-aren ikuspegitik diseinatutako interfaze industrialak, langileen errendimendua hobetzeaz gain, beraien motibazio eta inplikazioan eragingo duten emozio positiboak sortzea ahalbidetzen du, honela beraien ahalmenak handituz eta erabakiak hartzen eta ikaste prozesuetan lagunduz (Kaasinen et al., 2019). Enpresen interfaze industrialen diseinu eta ebaluazio prozesuetan UX-aren kontzeptuak txertatu ahal izateko, doktoretza honetan DEMOX (Design and Evaluation of Machine-Operators eXperiences) modeloaren garapena aurkeztu da. Modelo honek, langileek egungo interfazeekin duten esperientzia ebaluatzea eta hauentzat proposamen berriak planteatzea ahalbidetzen du. Horretarako, erabiltzailean oinarritutako ebaluazio metodo bat proposatzen du, eXperience Capturer (XC) deiturikoa eta adituaren ikuspegitik ebaluatzeko erraminta bat, HEMEI izenekoa. Hauen bitartez, Operator 4.0 kontzeptuko eginkizun berriak bereganatzea erraztuko duten interfaze berriak diseinatzeko lan metodologia bat eskaintzen du. Interfaze berri hauek, alde batetik, lanen efizientzia eta errendimendua eta, bestetik, langileen ongizate psikologikoa handitzen lagunduko dute. Lan honetan zehar DEMOX modeloaren garapen prozesua aurkeztu da. Lehen kapituluan, behin testuingurua aurkeztuta, tesiko helburu eta hipotesiak zein hauek aurrera eramateko ezarritako metodologia zehaztu dira. Bigarren kapituluan, UX-aren ebaluazioaren inguruko azterketa bibliografikoa erakutsi da, konkretuki ingurune industrialetan zentratuz. Hirugarren kapituluan, erabiltzailean oinarritutako XC ebaluazio metodoa aurkeztu da, honen balidaziorako egindako MHLAB I azterketa kasuarekin batera. Laugarren kapituluan, aditu ikuspegitik ebaluatzeko HEMEI erraminta azaldu da, baita hau osatzen duten aspektuak eta balidaziorako MHLAB II kasua ere. Bostgarren kapituluan, DEMOX modeloa aurkeztu da, aurrez aipatutako metodo eta erramintaz osatutako metodologia deskribatuz. Honekin batera, balidaziorako bi azterketa kasu azaldu dira, MHLAB III eta MHLAB IV. Azkenik, doktoretzako ondorio nagusiak jaso dira eta ikerketako etorkizuneko hainbat ildo zehaztu dira. Amaitzeko, tesian zehar lortutako ekarpen nagusienak honako hauek dira:  Interfaze digitalen diseinu eta garapenerako prozedura berri bat, User Centered Agile Design (UCAD) deiturikoa.  UX-aren ebaluaziorako metodo eta erraminten klasifikazio taula berri bat.  Interfaze industrialetako esperientzia ebaluatzeko eXperience Capturer (XC) metodo berria, zeinak aspektu pragmatiko eta esperientzialak interakzioko hiru faseetan aztertzen dituen, ikuspuntu multimetodo batetik erraminta kuantitatibo, kualitatibo eta monitorizaziokoak uztartuz.  Aditu ikuspegitik, interfaze industrialetako esperientzia ebaluatzeko HEMEI erraminta berria, interakzioko aspektu pragmatikoak eta esperientzialak kontutan hartuz  DEMOX
