No. of bitstreams: 1 5429.pdf: 4947647 bytes, checksum: 40e5d446c90d396131b9ff44de51ff13 (MD5) Previous issue date: 2013-05-28 / Financiadora de Estudos e Projetos / The emotions triggered during the use of an interactive system are an important aspect of the user experience. It is known that the emotions affect attention, perception, memory, behavior, learning, purchasing decisions, among others. Methods for evaluating the emotions are based on users self-report or assessments by experts. However, users are not always able to verbally express, name, or choose something that represents their emotions. In addition, experts can also perform partial or inaccurate assessments about the emotional experience. Thus, providing the designer with an alternative way to assess emotions and their impact on emotional experience, considering both views, allows a more comprehensive assessment and, it is believed, can minimize the problems encountered by unilateral evaluations. This study developed a hybrid approach to evaluate the impact of emotions in the emotional experience of users in a context of interaction with computer systems that considered: (a) the different aspects of emotion: cognitive appraisals, subjective feelings, behavioral tendencies, motor expressions and physiological responses, (b) different views including: users (the experience they communicate) and specialists (the experience they observe) and (c) assessments during and after the interaction time. The results of the pilot study suggest that the hybrid approach offers to the designer an alternative way of assessing the user`s emotional experience, through a collective analysis of the results obtained from the individual evaluations by experts and users, thus, leading to a more comprehensive assessment. / As emoções provocadas durante o uso de um sistema interativo são um aspecto importante da experiência do usuário. Sabe-se que as emoções afetam a atenção, a percepção, a memória, o comportamento, as decisões de compra, a aprendizagem, entre outros. Métodos para a avaliação das emoções baseiam-se em autorrelatos dos usuários ou avaliações realizadas por especialistas. No entanto, os usuários nem sempre conseguem expressar verbalmente, nomear, ou escolher algo que represente suas emoções. Além disso, os especialistas também estão sujeitos a realizar avaliações imprecisas ou parciais a respeito da experiência emocional. Dessa forma, fornecer ao designer uma maneira alternativa e balanceada de se avaliar as emoções e o impacto delas na experiência emocional possibilita uma avaliação mais abrangente e que, acredita-se, pode amenizar os problemas encontrados por avaliações unilaterais. Este trabalho desenvolveu uma abordagem híbrida para avaliar o impacto das emoções na experiência emocional dos usuários, em um contexto de interação com sistemas computacionais, que considerou: (a) os diferentes aspectos da emoção: avaliações cognitivas, sentimentos subjetivos, tendências comportamentais, respostas fisiológicas e expressões motoras, (b) diferentes visões incluindo: do usuário (a experiência que ele comunica) e dos especialistas (a experiência que eles observam) e (c) avaliações durante e após o tempo de interação. Os resultados do estudo piloto realizado sugerem que a abordagem híbrida oferece ao designer uma maneira alternativa de se avaliar a experiência emocional dos usuários, por meio de uma análise coletiva dos resultados obtidos pelas avaliações individuais dos usuários e dos especialistas, permitindo assim, obter uma visão mais abrangente de avaliação.

Dataset Evaluation Method for Vehicle Detection Using TensorFlow Object Detection API / Utvärderingsmetod för dataset inom fordonsigenkänning med användning avTensorFlow Object Detection API

Furundzic, Bojan, Mathisson, Fabian January 2021 (has links)
Recent developments in the field of object detection have highlighted a significant variation in quality between visual datasets. As a result, there is a need for a standardized approach of validating visual dataset features and their performance contribution. With a focus on vehicle detection, this thesis aims to develop an evaluation method utilized for comparing visual datasets. This method was utilized to determine the dataset that contributed to the detection model with the greatest ability to detect vehicles. The visual datasets compared in this research were BDD100K, KITTI and Udacity, each one being trained on individual models. Applying the developed evaluation method, a strong indication of BDD100K's performance superiority was determined. Further analysis and feature extraction of dataset size, label distribution and average labels per image was conducted. In addition, real-world experimental conduction was performed in order to validate the developed evaluation method. It could be determined that all features and experimental results pointed to BDD100K's superiority over the other datasets, validating the developed evaluation method. Furthermore, the TensorFlow Object Detection API's ability to improve performance gain from a visual dataset was studied. Through the use of augmentations, it was concluded that the TensorFlow Object Detection API serves as a great tool to increase performance gain for visual datasets. / Inom fältet av objektdetektering har ny utveckling demonstrerat stor kvalitetsvariation mellan visuella dataset. Till följd av detta finns det ett behov av standardiserade valideringsmetoder för att jämföra visuella dataset och deras prestationsförmåga. Detta examensarbete har, med ett fokus på fordonsigenkänning, som syfte att utveckla en pålitlig valideringsmetod som kan användas för att jämföra visuella dataset. Denna valideringsmetod användes därefter för att fastställa det dataset som bidrog till systemet med bäst förmåga att detektera fordon. De dataset som användes i denna studien var BDD100K, KITTI och Udacity, som tränades på individuella igenkänningsmodeller. Genom att applicera denna valideringsmetod, fastställdes det att BDD100K var det dataset som bidrog till systemet med bäst presterande igenkänningsförmåga. En analys av dataset storlek, etikettdistribution och genomsnittliga antalet etiketter per bild var även genomförd. Tillsammans med ett experiment som genomfördes för att testa modellerna i verkliga sammanhang, kunde det avgöras att valideringsmetoden stämde överens med de fastställda resultaten. Slutligen studerades TensorFlow Object Detection APIs förmåga att förbättra prestandan som erhålls av ett visuellt dataset. Genom användning av ett modifierat dataset, kunde det fastställas att TensorFlow Object Detection API är ett lämpligt modifieringsverktyg som kan användas för att öka prestandan av ett visuellt dataset.

Aueis en ny UX-utvärderingsmetod för engagemang vid interaktion med sociala robotar / Aueis a new UX-evaluation method for interaction with social robots

Ahmad Sheikh Sleiman, Shirin January 2021 (has links)
UX-designperspektivet är väsentlig vid utvärdering av interaktion med alla typer av robotar, men särskilt sociala robotar. Då dessa utvecklas för att utföra viktiga uppgifter i samhället såsom att vara sällskapsrobotar inom äldrevården, skolor med mera. User Experience Design-området har en bred samling av utvärderingsmetoder som människa-robotinteraktion-området kan dra nytta av. Denna studie syftar till att förbättra upplevelse vid interaktion med en social robot. För detta syfte har bland annat litteraturstudier genomförts där identifierades UX-aspekter som är relevanta att fokusera på vid utvärdering av förutsättningarna för engagemang i interaktionen mellan människa och social robot samt att det identifierades en kunskapslucka av tillgängliga analytiska utvärderingsmetoder inom människa-robotinteraktion (MRI). För att ta fram en ny analytisk utvärderingsmetod för att främja engagemang med en social robot användes en metodansats som är etablerad för att utveckla just utvärderingsmetoder. Designprocessen av den nya metoden bestod av fem iterativa faser som resulterade Analytisk utvärderingsmetod av engagemang vid interaktion med social sällskapsrobotar (AUEIS). AEUIS är designad för att utvärdera förutsättningarna för att uppnå engagemang vid interaktion med en social robot. Stort fokus lades på den femte fasen där versioner av AUEIS testades av flera UX-designers utifrån kriterierna att AUEIS ska ha hög validitet, vara användbar och ha bra lärbarhet. Testningen genomfördes med fyra UX-designer med olika erfarenheter inom MRI. Resultatet av testningen visade att en UX-designer utan tidigare erfarenhet av att utvärdera MRI kan använda AUEIS utan större problematik. Samtidigt, de framtagna aspekterna för att genomföra utvärderingen med var omfattande för att identifiera problem vid interaktion med en social robot. Det slutliga resultatet av detta är arbete är en komplett analytisk utvärderingsmetod. AUEIS består av sju aspekter som studerar föreutsättningarna för engagemang med en social robot. För att genomföra utvärdering med AUEIS finns det tre faser: Förberedelse, utvärdering och analys. Varje fas har några aktiviteter som följas för att få fram ett resultat om förutsättningarna av engagemang vid interaktionen med en social robot. Resultatet av utvärderingen med AUEIS kommer att bestå av kvalitativa och kvantitativa data. Den kvalitativa data som resulteras kan analyseras för att få en lista med vilka aspekter av engagemang som ej uppfylls av den sociala roboten. Den kvantitativa data kan ge en snabb överblick över vilka aspekter som har flest problem och vilka problem är mest allvarliga. AUEIS utvärderar förutsättningar för engagemang vid interaktion med en social robot och är begränsad till detta på grund av att den utvärderar om den sociala roboten uppfyller de förutsättningarna för engagemang. Därför användarensupplevelse av engagemang utvärderas enbart på ett mindre sätt utifrån hur mycket den sociala roboten uppfyller de förutsättningarna för engagemang. En framtida forskning och utveckling av AUEIS hade varit intressant och behövs för att AEUIS ska kunna utvärdera om användaren är engagerad och i vilken omfattning är hen engagerad. En annan aspekt som kan studeras är användarens engagemang under lång tidsinteraktion, korttidsinteraktion eller olika faser av engagemang. Exempelvis hur utvärderas att användaren påbörjar engagemang med en social robot och hur ska det utvärderas att engagemanget hålls och fortsätter eller om den avbryter och varför utifrån användarensperspektiv. I kapitel 5 (Slutresultat AUEIS-metoden) presenteras metoden samt detaljerade instruktioner över genomförandet presenters i Bilaga 7. / The user experience design (UX) perspective is essential when evaluating interaction with all types of robots, but especially social robots. As these are developed to perform important tasks in society such as being companion robots in geriatric care, schools and more. The User Experience Design area has a wide collection of evaluation methods that the human-robot interaction area can benefit from. This study aims to improve the experience of interacting with a social robot. For this purpose, literature studies have been conducted where UX aspects were identified that are relevant to focus on when evaluating the conditions for engagement in the interaction between human and social robot. A knowledge gap was identified of limited available analytical evaluation methods in human-robot interaction (HRI). In order to develop a new analytical evaluation method to promote engagement with a social robot, a methodological approach was used to develop evaluation methods. The design process of the new method consisted of five iterative phases that resulted in an Analytical evaluation method of engagement in interaction with social companion robots (AUEIS). AEUIS is designed to evaluate the conditions for achieving engagement when interacting with a social robot. Great focus was placed on the fifth phase where versions of AUEIS were tested by several UX designers based on the criteria that AUEIS should have high validity, be useful and have good learnability. The testing was performed with four UX designers with different experiences in HRI. The results of the testing showed that a UX designer without previous experience in evaluating HRI can use AUEIS without problems. At the same time, the aspects developed to carry out the evaluation were comprehensive to identify problems when interacting with a social robot. The result of this is work is a complete analytical evaluation method. AUEIS consists of seven aspects that study the conditions for engagement with a social robot. To evaluate with AUEIS, there are three phases: Preparation, evaluation, and analysis. Each phase has some activities that are followed to obtain a result about the conditions of engagement in the interaction with a social robot. The result of the evaluation with AUEIS will consist of qualitative and quantitative data. The qualitative data that is obtained can be analyzed to get a list of which aspects of engagement are not fulfilled by the social robot. The quantitative data can provide a quick overview of which aspects have the most problems and which problems are most serious. AUEIS evaluates the conditions for engagement when interacting with a social robot and is limited to this because it evaluates whether the social robot meets those conditions for engagement. Therefore, the user experience of engagement is evaluated only in a minor way based on how much the social robot meets the conditions for engagement. Future research and development of AUEIS would have been interesting and needed for AEUIS to be able to evaluate whether the user is engaged and to what extent is. Another interesting aspect to study can be the user experience of engagement whether it is during long-term interaction, short-term interaction, or different phases of an engagement. For example, how to evaluate that the user begins engagement with a social robot and how should it be evaluated that the engagement is maintained and continues or if it interrupts and why from a user perspective? Chapter 5 (End result the AUEIS method) presents the method and detailed instructions on implementation are presented in Appendix 7.

Automating the harm evaluation methodology

Rubiño Espinosa De los Monteros-Aliaga, David, Rodriguez Arriaza, Cristina January 2023 (has links)
The advance of automation in industry has meant that in recent years companies have begun to look for other ways to improve the efficiency of their productivity. Automation is present in all types of activities in industry, however, there are certain activities that cannot be fully automated due to the difficulty to develop them. Therefore, this activity must be handled by the worker and their safety must always be considered. In this aspect, ergonomics is in charge of studying the comfort and safety of the workers. Numerous methods of studying ergonomics can be found today, but the one that this project will focus in is the Hand and Arm method (HARM) which nowadays is performed manually by ergonomists. This method requires a great deal of effort on the part of ergonomics professionals in order to obtain reliable and accurate results. In addition to this disadvantage, the time required to perform each evaluation is also high. As the HARM method is an observational evaluation method, the study must sometimes be made by more than one ergonomist to reach a valid conclusion. This project presents the development of a system that automates one such ergonomic evaluation method called the Hand-Arm Risk Assessment Method (HARM). For this purpose, high-precision sensors are used to measure the different motions of a user's joints, as well as pressure sensors that measure the forces exerted by a worker while performing an industrial activity. This project is presented as a solution that improves both accuracy and reliability and reduces the time needed to perform the HARM method evaluation. The created tool serves as a link between the ergonomist and the various hardware systems in use, and it features an intuitive user interface that enables both data collection and visual depiction of the evaluation's findings. The topic of sustainable development, which is being addressed as a result of the development of the tool, is another crucial aspect of this project. Some of the objectives outlined in the UN's sustainable development guidelines have been met as a result of the intimate relationship between ergonomics and sustainability. Among these goals are good health and well-being (Goal 3), work and economic growth (Goal 8), industry, innovation, and infrastructure (Goal 9), gender equality (Goal 5) and reduced inequalities (Goal 10). / <p>Utbytesstudenter, Universidad de Málaga, Spanien</p>

Optimization of a welding gun use case by using a time-based ergonomics evaluation method

Mora Quiles, Elia January 2022 (has links)
Nowadays virtual simulations are commonly used to solve problems regarding worker well-being or productivity in manufacturing companies. However, when it comes to finding a solution to one of these two objectives, the other usually tends to be secondary. In order to solve this problem, the Ergonomics in Production Platform (EPP) has been developed within research efforts at University of Skövde, which through the use of optimizations is able to obtain solutions where both objectives are taken into account. In turn, in order to address worker well-being, EPP makes use of the digital human modelling (DHM) tool. DHM tools are often used to evaluate simulations focused on studying human-machine interaction. However, as these software evolve and start to be able to reproduce complete motions, before they were only considering frames, new methods are needed to be able to assess risk factors such as time and prevent the occurrence of musculoskeletal disorders (MSDs). In order to assist in the development of EPP optimizations for simulations carried out in DHM tools, the time-based observational method RAMP was implemented, specifically the posture-related criteria of RAMP II. Using the Design and Creation research methodology, a welding gun case study located in China offered by Volvo Cars was used to evaluate the results of the optimizations carried out with EPP. For the evaluation of this case study, a manikin family of 10 members representing key cases of the Asian population was created for this task. Later, this task was recreated in IPS IMMA, where the 10 cases interacted with 3 welding guns to weld different spots on a piece. The analysis of this case study consisted of two distinct phases where the results of RAMP II implemented in EPP could be evaluated. The first phase focused on analyzing initial results of three different trajectories for all members of the family. The second phase consisted of optimizing one of the trajectories analyzed in the previous phase in such a way as to find the best welding angle of the gun to improve the results of the worst case in the first analysis. Three different factors were evaluated in this phase: RAMP II results versus the new angle, RAMP II results versus the results of other methods and the effect of productivity versus worker well-being. The results showed that welding angles of 116º and 80º were able to improve the values of the RAMP II criteria for the most disadvantaged manikin in the welding task. At the same time, it was observed that the higher the percentage of value added time, the higher the risk obtained in the analysis, worsening the worker's well-being.
