Lately, Automatic Speech Recognition (ASR) has improved in both performance and popularity and today the technology can be found in many different products, often in the form of a Voice User Interface (VUI). There are numerous factors to consider when developing a system using this technology. It is essential to comprehend both the user’s experience of using the product and the performance of the ASR. In terms of the user experience, only the user can tell you what is important, which is why user testing is a necessary part of further development. In this study, a test was designed to perform a comprehensive remote user test of the dictation feature Notebook Voice Control in the product BIOVIA Notebook. The aim of the user test was to understand what factors affect the performance of the feature, and when a user is satisfied. To carry out the tests a web-application was designed, created, and deployed. The web-application was integrated with the API of the product being tested and guided the participants through the tests as well as captured the test data. From the test results, it was clear that accurate recognition was highly important in terms of user satisfaction. In order to produce an accurate dictation, dictating in your native language seemed to be a success factor as well as having dictation experience. If you lack dictation experience, training appears to help. The errors that were the most remarkable in the tests and would need immediate attention were errors in the categories of numbers, abbreviations, units, and field-specific words. The issue of the time spent correcting errors was raised, and for some, this was what made them argue that the tool was currently not useful. The majority were positive towards the tool but wanted it to be a bit better, or perhaps they just have to practice using it a bit more. / På senaste tiden har taligenkänning ökat i både träffsäkerhet samt popularitet. Idag är tekniken implementerad i en rad olika produkter, ofta i form av ett röstanvändargränssnitt. Under utvecklingen av ett system som använder denna sorts teknik finns det ett antal faktorer att tänka på. Det är väsentligt att förstå både användarens upplevelse samt hur bra taligenkänningen är. Beträffande användarupplevelsen är det endast användaren som kan berätta vad som är viktigt, vilket är varför användartester är en nödvändig del av vidareutvecklingen. I denna studie designades ett användartest för att utföra en fullständigt utvärdering av dikteringsverktyget Notebook Voice Control som nyligen implementerats i produkten BIOVIA Notebook. Målet med testerna var att förstå vilka faktorer som påverkar träffsäkerheten av taligenkänningen samt när användaren är nöjd med verktyget. För att genomföra testerna skapades en webb-baserad applikation där testerna utfördes. Applikationen var integrerad i den testade produkten via dess API och applikationens uppgift vara att leda deltagarna genom testerna samt fånga testdata. Från resultatet av testerna var det påtagligt att en träffsäker taligenkänning var mycket betydelsefull för att användarna skulle vara nöjda. För att få en så korrekt transkribering av dikteringen som möjligt fanns det två tydliga faktorer som påverkade mest: att vara en erfaren dikterare samt att diktera på sitt modersmål. Om du inte är en erfaren dikterare verkar övning hjälpa med att förbättra dina dikteringsresultat. Av de felaktigheter som uppstod under dikteringarna, var de väsentliga numeriska värden, förkortningar, enheter samt ämnesspecifika ord enligt deltagarna. Dessa felaktigheter var sådana som deltagarna tyckte var tvungna att rättas till på en gång. Tiden som läggs på att rätta fel togs också upp som ett problem, på grund av detta tyckte ett antal deltagare att dikteringsverktyget inte var användbart i nuläget. Majoriteten var dock positiva till verktyget men ville att det skulle vara lite bättre för att använda det, eller så behövde de kanske öva lite mer.

Energy feedback systems have the potential to support households in utilizing their energy more efficiently and making sustainable decisions. However, the feedback must be carefully designed and delivered to resonate with the individual and change behavioral patterns. This thesis investigates the prerequisites needed to increase awareness and engagement of energy usage and presents a prototype of an energy feedback mobile application. The requirements were found through a qualitative study where eleven households of GodEl with varying characteristics participated in semi-structured interviews. The responses were analyzed through thematic analysis and contributed to a deeper understanding of an energy feedback system’s user needs and requirements. A prototype was created aiming to meet the needs and requirements found. Results suggest that households respond to feedback individually. However, the data presented in the system must be reliable, relatable, and assist the user in decision-making to accommodate the individual needs of each household. Evaluation through user testing reveals that the prototype would increase the users’ knowledge and awareness. However, the prototype’s effect on behavioral changes could not be confirmed without letting the users test the system over some time in a real-world context.

This report is the outcome of an exam work made in interaction design, bachelor degree, at the School of Arts and Communication, Malmö University. Working in collaboration with the childhood obesity unit, Region Skåne, our aim was to fulfill their request of a web based application preparing the children for treatment at their facility. Furthermore the application intends to give the children knowledge concerning obesity as well as teaching them how to obtain a healthier lifestyle in terms of provision and activities. The application concerns children in different ages and therefore different stages of their learning abilities. Our conclusions are that they need to be challenged and obtain feedback in different ways to get motivated. For a younger child it is often enough with feedback in terms of a voice approving their choices. For an older child however it is important to constantly challenge them in order to maintain their interest. This can for example be achieved by making tasks harder but still obviously reachable within the children’s capabilities. Adding different difficulty levels is another way to motivate and challenge children in different ages and stadiums of development. The report leads you through our complete design process, from our initial ideas to our latest prototype. We describe what context in which we have been working, the methods we have been using, and finally a discussion concerning the results and conclusions we have made.

Detta arbete är en jämförande studie mellan mätningar inom användbarhet. Studien jämför en heuristisk utvärdering med ett användartest, med inriktning på ekonomi och resultat. Syftet är att belysa den ekonomiska aspekten mellan de två metoderna. Samtidigt undersöker studien om heuristisk utvärdering är en metod som lämpar sig som beslutsunderlag. Studien är genomförd på ett tryckeri där tryckeriets IT-system har testats och utvärderats utifrån de två metoderna. Studien baseras på kvalitativa och kvantitativa metoder så som strukturerade och ostrukturerade intervjuer, observationer och enkäter.Arbetet behandlar användbarhet som begrepp och metoder för hur användbarhet mäts. Relevant teori presenteras i teoridelen och behandlas i diskussionen. De båda metoderna var relativt lika varandra. Den stora skillnaden ligger i att användartestet gav mätbara resultat medan den heuristiska utvärderingen resulterade i en givande diskussion. Ur ett ekonomiskt perspektiv var den heuristiska utvärderingen betydligt billigare att genomföra. Undersökningen visar att den heuristiska utvärderingen fungerar bra. Dock bör metoden undersökas ytterligare för att styrka påståendet. / Resource-saving methods in usability This essay is a comparative study of measuring usability. The study compares a heuristic evaluation with a usability test, with focus on economy and performance. The aim is to highlight the economic aspect between the two methods, also if the study of heuristic evaluation is a method suitable for decision-making. The study is conducted on a printing company where the company’s IT systems have been tested and evaluated on the basis of the two methods. The study is based on qualitative and quantitative methods such as structured and unstructured interviews, observation and questionnaires.The study deals with usability as a concept and different methods for measuring usability. Relevant theory is presented in the theoretical part and is discussed and addressed in the discussion.Both methods were relatively similar. The major difference is that the user test yielded measurable results, while the heuristic evaluation resulted in a fruitful discussion. From a financial perspective, the heuristic evaluation is significantly cheaper to implement. The study shows that the heuristic evaluation works well. However, the method should be further investigated to prove the claim.

As digital interactions become increasingly integral to our daily routines, ensuring web accessibility for all users is crucial. User experience designers play a big role in creating online environments that are not only usable, but also informative and enjoyable. The European Accessibility Act is a new directive from the European Union, stating that certain products and services must be accessible by 2025, benefiting an estimated 87 million Europeans who have disabilities or temporary impairments. Previous research on Swedish websites has found that requirements are often not fulfilled when it comes to accessibility. This thesis investigated current accessibility practices among Swedish user experience (UX) designers and evaluated their preparedness for compliance with the European Accessibility Act. The results of the interviews show that the Act provides several motivating factors for improving accessibility measures in organizations. Through expert evaluations of the design practices, a set of guidelines is presented, aimed at providing guidance for companies and designers in creating an inclusive design culture while complying with the Act.

The implementation of In-Vehicle Intelligent Transport Systems (ITS) is becoming a common occurrence in modern vehicles. Automobile manufacturers are releasing vehicles with many forms of sophisticated technologies that remove much of the responsibility of controlling an automobile from the driver. These In-Vehicle Intelligent Transport Systems have stemmed from a genuine need in regards to road safety, however there are advantages and disadvantages associated with ITS. Each different form of technology has its own inherent compromises in relation to road safety, driver behaviour and driver comfort. This thesis outlines the benefits and detrimental effects associated with current In-Vehicle Intelligent Transport Systems and details the development and user interface testing of an adaptive brake light. The adaptive brakelight concept aims to provide drivers with the advantages of an In-Vehicle ITS whilst removing the disadvantages. The technology will help drivers judge the braking pattern of the car in front, thus allowing them to react appropriately and potentially reducing the occurrence of rear-end crashes. The adaptive brake light concept was tested in comparison to a standard brake light and BMW inspired brake light in a series of user interface tests. The adaptive brake light was shown overall to be an improved method of displaying the varying levels of deceleration of a lead vehicle. Whilst different age and gender groups responded differently to the adaptive brake light, it was shown to be of benefit to the majority and the most at risk groups responded positively to the adaptive brake light. This research shows that an adaptive brake light can provide a benefit in regards to road safety when compared to a standard brake light interface. It is hoped that further development of variable brake lights will result from this research and possibly lead to the implementation of the technology to automobiles and other forms of transport.

This thesis work examines how the user experience of mobile games can be evaluated with the use of session recording tools. The thesis project was carried out at the mobile games development company MAG Interactive, and the aim was to produce a workflow for the company with guidelines for how to conduct user testing with session recording tools for mobile devices. In order to evaluate the tools and services, and to develop the workflow, several user tests have been conducted. When using mobile session recording tools, it is possible to record the screen of the device, the microphone input and in some tools also the front camera input while the user is playing the game. Recording the test session makes it easier to understand and evaluate the player experience of the game and also to identify usability issues. The thesis also covers other parts necessary when conducting user testing besides the actual session recording tool. These are test set up (instructions, tasks etc.), integration, distribution of the test and the application and also analysis of the recorded test session.

This diploma thesis analyses the phenomenon of adapting e-shops selling electronics and computers to the Generation Y in the terms of website usability. The theoretical part is divided into three main chapters. The first chapter describes a consumer behavior, shopping behavior and the difference between shopping behavior in physical stores and their cyberspace counterparts. The following chapter deals with the Generation Y and its characteristics. The last part describes the web usability itself, its common flaws in usability and the topic of web usability testing. The practical part is dedicated to a web usability testing on selected e-shops. The testing itself  was conducted by the user testing method, where all the tested subjects belonged to the Generation Y. A questionnaire and a guided interview were also used to gather information for the study. The survey revealed many elemental flaws in the terms of  web usability of studied samples and presented suggestions how to correct them. A big problem was found mainly in the design structure of the sites. Users were under constant advertisement pressure which has neutral or even negative effect on the Generation Y.

The thesis deals with the analysis and development of responsive interface of online stores' websites. The work is divided into several chapters, which can be divided generally into two main parts, theoretical and practical. In the first theoretical part there are different perspectives and analyzes, that need to be defined for web development and possibilities of progression of the web sites along with testing the correctness of individual steps and procedures, explained. The practical part consists in the implementation of the proposals and creating designs typical for company based on informations gathered from the analysis of the accessibility and usabiity of original pages and pages of competition. Part of crafting proposals and graphics is user testing, processing comments and found bugs. Thanks to these aquired knowledge there is in the final part designed and implemented new look along with a basis for possible further development and expansion opportunities in the future.
