    Functional Programming and Legacy Software Using PureScript to Extend a Legacy JavaScript System2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Legacy systems are everywhere. Immense resources are placed on fixing problems caused by them, and on legacy system maintenance and reverse engineering. After decades of research, a solution has yet to be found. In this thesis, both the viability of using purely functional programming to mitigate problems of legacy systems is investigated, as well as the possibility that purely functiona lprogramming can lead to code that is less likely to lead to legacy problems in the first place. This was done by developing a genome browser in PureScript that embeds, interfaces with, and extends, an existing genome browser written in JavaScript.The resulting codebase is examined, and various characteristics of purely functional programming, and how they helped solve or avoid problems related to legacy systems, are presented. In Conclusion, PureScript is found to be an excellent tool for working with legacy JavaScript, and while the nature of the project limits the conclusions that can be drawn, it appears likely that using purely functional programming, especially with a language suchas PureScript that provides a powerful type-system for ensuring program correctness, leads to code that is more easily understandable, and thus avoids the problems of legacy code.

    Making use of automation: Designing a performance driven marketing tool for Smart video2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Online advertising is a multi billion dollar industry used by marketers all over the world. Online advertising methods enable merchants a way to deliver information that is targeted to those consumers who potentially would value the information the most and are most likely to act on it. This can be done by using data collected from people through search history, social media profiles and other services when distributing personalized ads that fit peoples corresponding profiles. With a greater amount of options available for ad targeting and more detailed statistics about online ad performance than ever before, the workload for marketers is constantly increasing. This is where automation can be of major assistance.

    This thesis explores how different Levels Of Automation can be used in online marketing to assist marketers in the process of creating and following upon ad campaigns. The iterative user experience design process have been used to develop a design proposal of a performance driven marketing tool for the Smart video platform. First a research study was conducted in order to gather information about online advertising and automation in interface design. The result from the research was then analyzed and a lo-fi prototype was constructed. The prototype was continuously tested and evaluated in order to improve the design. Finally a hi-fi prototype of the marketing tool was implemented and usability tested. The design proposal illustrates how automation can be used to propose or automatically select a market strategy (that is based on previous ad performance data) for online advertisements. The design proposal uses colors to indicate what level of automation the system is working on. The results from the usability testing, with support from previous studies indicates that information and feedback are two of the most important aspects to consider when designing for automation.

    Designing for diversity: A tablet-based ePRO system to assist stroke rehabilitation2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis, a web- and tablet-based ePRO system to assist stroke rehabilitation was developed in an iterative and user-centered design process involving elderly and people with personal and professional experience of stroke. A limited part of a paper-based PRO questionnaire was transitioned into the developed electronic format and evaluated on five stroke patients using a qualitative usability testing approach, including observation and feedback through discussion and a post-test questionnaire. The results indicated that a tablet-based ePRO questionnaire could be both usable and applicable in this target group, with a majority of the patients preferring it over the paper-based questionnaire. Furthermore, the findings suggest tapping problems and cognitive overload to be specifically considered when designing ePROs for this target group, which may also benefit from a certain level of adaptivity to achieve personalized user interfaces and increased accessibility.

    Shopping for emotion - Evaluating the usefulness of emotion recognition data from a retail perspective2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study researches the usefulness of emotion recognition technology and respective data within the retail space. Emotion recognition is a relatively novel technology that promises to pinpoint a subjects emotional state. While the use cases could be many for a retailer there is still little available research on how to implement these tools and how to interpret their data. This study aims to provide an answer to those questions by reviewing current studies in emotion recognition and by setting up a rudimentary field test to compare data gathered by the Microsoft Emotion Recognition service with standard user satisfaction measurements. The responses are examined to determine if a subjects’ identified emotion has any connection to their perceived satisfaction with an experience. No such connection is found within the gathered data however, but several other points of interest are discovered. The study concludes that current emotion recognition tools may not live up to their hype and offer little in terms of useful data. They tend to require exaggerated emotional expressions and perform subpar to humans in many cases. The reasons for this, and possible improvements to these tools are also discussed.

    Designing Touch Interaction for a 3D Game2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The marketshare of touch devices is increasing, and so is the number of games on that platform. As touch devices have become almost as powerful as game consoles, games from the PC and console platforms are being adapted to these touch devices. Console and PC games often feature quite complex controls which can be difficult to implement on touch devices.

    This thesis details the design, implementation, and evaluation of methods of interacting with a 3D game on touch devices. The project was performed at Dohi Sweden on the game MilMo, which is a 3D game currently available on the web.

    The results of this projects was two prototypes that were evaluated using both user tests as well as heuristic evaluation. The evaluation show that one of the prototypes was preferred because it was more similar to other existing solutions.

    Development of a Second Screen Content Platform2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Smart televisions are becoming more common in households and with the added capability to both connect to the internet and launch applications they have the possibility to help create a more engaging interactive experience. An interactive experience that extends beyond the classic remote control and into the personal second screen of every viewer. Second screens are frequently used while watching television making them ideal for creating audience participation and extending the television experience.

    By looking at upcoming technologies related to interactive television and their interaction with second screens as well as design guidelines related to second screens, interactive television and social television we create a platform for prototyping web-based interactive television.

    The platform uses a system based on the technologies found in upcoming televisions and consists of a client and server. The server acts as a television that can be detected by the clients using Universal Plug and Play and then open web pages sent by the client. The client presents a user with a list of second screen content which can include applications, web sites and interactive content shared between television and second screen.

    Video approval app for iPad2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The goal of this master thesis project was to design a concept for an iPad app that solves the problem of collecting feedback around a video clip in a video production. The concept targeted an end user which used the mobility of the iPad to give feedback on video clips from wherever, collaborating with other people involved in the video production. A background study was performed covering mobile app development, guidelines for designing mobile systems and guidelines for designing collaborative systems. With data gathered from interviews with people working with video, a design process including ideation, sketching, interface mockups and interactive mockups iterated the concept into a proposal for a video commenting tool for iPad. The app lets the user add comments onto the timeline with text, drawings and voice recordings as well as keeping him or her up to date with the discussions around the video clip. The result of the project can be used as a reference document for further development.

    Enhancing the User Experience for a Mobile Signup2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The last couple of years email has stretched beyond the desktop computer and into the mobile devices. Visiarc, a company in Linkoping, developed an application called Mobile Documents to cater for this new market. With the use of Cloud Computing techniques, the application lets the user access large attachments sent to them to view them in the device without having to download any file to the device itself.

    The main focus of this thesis is the signup for Mobile Documents on the Android platform, utilizing methods and techniques from the field Human-Computer Interaction to develop a new design for the signup process with high regard to the common user, and integrate it into the existing architecture of the service. The thesis covers theoretical aspects that were taken into account regarding usability guidelines and heuristics when developing for the end consumer software market. The developed signup covered in this thesis was integrated into the new release of Mobile Documents for Android in February 2011.

    In addition to featuring the work at Visiarc the thesis contains two chapters discussing particular aspects of mobile technology, \Utilization of Cloud Computing in Mobile Applications" and \Designing for Small Screens". The former discusses the recent development of Cloud Computing and how that can be applied to also include mobile applications. The latter presents guidelines when developing the GUI for small screen devices.

    Graphical Interface for Measuring the Effect of Cosmic Radiation on Computer Memory2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    When protons or neutrons pass through computer memory, there is a small risk that they turn a 1 into a 0, or vice versa. At flight altitudes, there is a lot of neutron and proton radiation and the risk of a bit flip is high. Therefore, computer memory needs to be tested to see what types work best in radiating environments. The process for such testing requires test equipment, and the test equipment needs a computer interface.

    This report describes an interface design and its development, including the methods, the process and the final result. The methods used were, among others, the iterative design process, design patterns and lo-fi prototyping. The design and development process covers not only the sketches and the thought process surrounding them, but also a week of first-hand experience in the test laboratory. The final result is a new graphical user interface for the test program.

    Responsive Web Design – Evaluation of Techniques to Optimize Load Time2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Responsive Web Design has, in short time, become a common method to create websites that automatically adapt the layout to different screen sizes. However, critique has been raised about poor performance due to large page size and high number of requests to the web server. The aim of this study is to evaluate techniques to optimize the load time of a responsive website. This is done by creating a prototype in the form of a responsive website, which is used as a base for the optimization. Tests are performed by measuring the page size and the number of requests when using four different optimization techniques. The results show that combining optimization techniques can dramatically reduce the page size and the number of requests. Consequently, this has a positive impact on the load time of the website. Furthermore, the Mobile First approach is important in responsive web design as it prioritizes the use of mobile devices and as a result highlights the significance of web performance. It is also suggested to set a Performance Budget early in web development projects in order to avoid slow websites and spread awareness about the importance of performance.

    Usability Improvement and Re-Design of SIMAIR - an Air Quality Assessment Tool2012Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The thesis propose a new design solution of the web application and air assessment tool: SIMAIR, a product of The Swedish Meteorological and Hydrological Institute (SMHI). The current solution of SIMAIR is outdated regarding the interaction and visual apperance, as a result it is in need of a user adaption. No user study has been perform earlier and for that reason SMHI needs an increased knowledge about the users. The objectives of this thesis are therefore to perform a user study, develop a more user-friendly design and implementan interactive prototype of the new design solution.

    By using the design method Goal-Directed Design, a design target of the wide spread user group was found and personas of the user archetypes were developed. By narrowing down the target audience, the new design was more well defined and the chances to create a product that satisfied the users' needs increased.

    The design target and the personas was used to find goals and motivations, as well as aptitudes and attitudes, of the users. "Seriousness", "Professionalism" and "Reliability" were the objectives for the new design. They formed the basis for the creation and development of a modernized and user-friendly graphical user interface of SIMAIR. The prototypeto visualize the new interface, was developed by using HTML5, CSS3 and the JavaScript libraryJQuery. These technologies are also, well suited for further development and usability improvement of SIMAIR.

    User Perception of Reliability and Design of a Mobile Pension Application2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The increasing acceptance of using mobile devices and applications to perform every day tasks has created a market for applications handling personal assets of a user. Applicationsmanaging transactions and personal and financial information place demands on the design and implementation. One issue to consider is how to support the user perception of reliability. A literature review, accompanied by a user study, show that important aspects to have in mind are trust, privacy, familiarity and security. These aspects can be incorporated in the design by, for example, providing accurate and timely information and relevant feedback. Design guidelines presented by the above mentioned study of perceived reliability, are used while designing an application aimed to manage pension errands. Functionality supported are viewing detailed information of ITP 1 insurances and changing funds of a specific insurance.

    Abstract [en]

    Through observations, interviews, conversations and evaluation, knowledge regarding the internal invoice system at Riksbyggen was made. The knowledge made it possible to find areas where users have problems in interacting with the system and where errors made by users mostly occur. Concerns had been raised regarding the current solution preventing workers from performing their duties when their help is needed elsewhere. The results are two design proposals containing information that has been visualized and ideas of how to combine different sources of information to provide users with more knowledge. To evaluate how successful the results are a heuristic evaluation was made on the prototypes' designs.

    Design of a Household Concept Motivating Sustainable Consumption Behavior2011Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In common households today the awareness of the electricity, water and waste consumption are rather low. This generates a behavior that conicts with the existing goals of sustainable living. Together with Stockholm City and other companies The Interactive Institute is working with a project called Stockholm Royal Seaport, where the goal is to implement a solution for how smart grids and visualizations in the household could motivate a change of this behavior. This master thesis examines how to do this using an in-home display and ambient interfaces in an apartment. In order to motivate the users the goal was to create a dynamic and exploring solution, that would not cause them to loose interest. The result was an in-home display interface based on dynamic home screens, social comparison and achievements, and a couple of ambient interfaces located in the household. A presentation video was made in order to visualize the coherent solution.

    Designing Search User Interfaces2011Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Searching for information has become a natural task in today's society. Nowadays more than 2 billion people are connected to the Internet and using some kind of search functionality for finding information is a central activity. The amount of digital information that is produced puts high constraints on the design of search interfaces.This master thesis report presents a proof-of-concept design and implementation of a search user interface. The main focus of the project is usability, especially in the aspects of navigation and content presentation. There are many features that can support the user during the search activity and this interface has been developed on the basis of these features. The report describes an iterative user-centered design process that served as the foundation during the proof-of-concept development. The target user group has been involved throughout the project and the design has been evaluated on several stages in the design process and the proposed interface was well received by the target users. An interactive high- delity prototype was implemented in Adobe Flex 3 for the purpose of evaluation and demonstration.

    How to provide a user friendly search interface based upon a libraries Open Public Access Catalogue2011Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today many libraries offer their services via Internet and reach billions of visitors in different ages. The problem is that most of these library web sites are not customized for the users and they don’t deliver a good user experience. In this thesis we have studied both the interface and the users of an Open Public Access Catalog called CS Library. We found out how the users use the current system and how they want to use it. To achieve this we gathered data with different user studies at the Ume°a city library. A new interface was developed from the outcome of our user study. We created a set of guidelines that were followed when a new user customized design was developed for CS Library. The new design offers a better user experience and is customized by the users needs, desires and thoughts. The new design has been implemented as an interactive prototype with HTML, CSS, Javascript and Actionscript to convey a better feeling of the interface.

    Usability Analysis and Redesign Suggestions for a SaaS ERP Invoice System2011Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    24SevenOffice is a business software application delivered through an on-line rental computing approach called Software-as-a-Service (SaaS). Since its launch in 1996 the application has had a steady growth of functionality and, as a side effect, increased significantly in its complexity. That the application has turned out complex was arguably inevitable considering the varied and complex problems it is addressing. But as a result this led to some parts of the business software being complicated to learn and use. Fortunately, good interaction design can manage complexity by providing organization, structure and an underlying logic that once mastered makes everything fall into place. This thesis is analyzing one of the systems core components, the invoice system, and provides redesign suggestions for increasing its usability. The used methods are modeled on Cooper's Goal-Directed Design Methodology, which includes: Personas, Scenarios, Design Principles and Design Patterns. Suggested solutions address both tweaking the existing solution and presenting a vision for a major rework.

    A program that createsprograms, how to graphicallycreate a mobile phoneapplication2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    There is pressure on mobile phone application developers. With the success of the iPhone in 2007 advanced mobile phones are getting more and more common, and with them a market for applications, programs for mobile phones has exploded. The thesis discusses the possibility of helping developers to lift the focus from the code and instead graphically visualize the system architecture, the design of graphics and the functionality of the application. First a "proof of concept" program was implemented that allows a user to create the graphics for a mobile phone application using only drag and drop. Then a design proposal was created with the goal to allow developers with basic programming experience to create mobile phone applications using drag and drop. The proposal was heuristically evaluated with the help of a checklist consisting of eleven Gestalt laws and ten heuristics that were applied on sketches of the design proposal constructed in Adobe Photoshop CS4. The results from the two parts were merged. To create applications fast and with low programming experience, using drag and drop is a strong candidate to solve the problem.

    A TV Interface for Set-top boxeswith Social Functionality2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The fact that digital TV and set-top boxes are connected to Internet opens up for many possibilities. One concept that has emerged because of this is social TV, which has to do with social functionality in combination with watching any type of content: on TV or on the web. In this report an interface for digital TV is presented with social features. The challenge with developing this is that the viewer is in a lean-back mode when watching TV and not up for complicated interaction tasks. Because of this, the aim of the design was to have relevant social features, that will fit in a TV context. This meant that they would support social activities that are already being made when watching TV and movies and also demand a very simple interaction. A concept was developed through literature studies and the design process. The result is a interface with a simple navigation that constitutes of five widgets, all that supports different kinds of watching behavior and social activities. The interface has been implemented to an interactive prototype that conveys the look and feel of the concept.

    Design aspects in a mobile biofeedback system - developmentof a new interface concept usingdesign qualities2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    It has been established that long term stress can lead to chronic illness of cardiac disease and vascular disorder. In the way people live their lives today they are surrounded by stress and they contribute to the stressful society when they constantly chase the time. The Mobile Life Centre explores how the system Aective Health can get people to reect up on their stress levels and connect that to their everyday activities by using bio sensors and a mobile phone. The bio sensor data visualization in the interface of the system is today tied to time. Since time is perceived dierently from person to person that is something that has caused problems for the design team of Aective Health. This thesis examines how dierent representations of time in user interfaces can be used to mediate the design qualities of subjective time, aliveness and uency in the Aective Health system. As a result from investigating the time aspect and how time can be visualized in a subjective way a suggestion for a design solution was developed.

    Designing a non-distractive center-stack interaction2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Car brands are today competing over having the most advanced technology in their cars. The drivers today control the stereo which include radio, CD, MP3 and satellite radio. They also control the climate, the GPS, surf the Internet and show a DVD for the kids in the backseat and so much more from the centerstack. All these functions have clattered the center-stack with buttons, "smart" interaction knobs as well as scroll wheels. The buttons feel the same and thereby force the driver to change focus from the main-task, which is driving, to the center-stack. The same attention demanding situation are with the interaction knobs. In order to see the feedback the interaction knob provides, the driver needs to look at a screen located somewhere in the center-stack. World wide driver inattention causes around 60.000 deaths each year. This master-thesis describes the process of designing a non-distractive center-stack interaction. The reader will be introduced to the background of the problem, the dierent design suggestions that were taken into consideration as well as a given full presentation of the nal result. The paper also presents an in-depth study that provides a few guidelines for designing a detached touchscreen input from output.

    Designing and implementing a word quiz in Flash2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Education is evolving and is taking advantage of the digital society. Classrooms, study material, communication, etc. are in their traditional senses fading away and being replaced by their digital counterparts. Because of personal computers, faster Internet, and instant information access the need for Web-based education services has appeared. GoLingual is an on-line platform for language learning. It offers education in six languages and supplies all the necessary tools to learn whenever a user chooses to, and by his or her own preferences.In an on-line environment such as GoLingual it seems suitable to lighten up the education and adopt the paradigm of "learning by playing". Therefore it was decided to add a game to the platform. This paper contains an in-depth study about games for education, how they contribute, and what their drawbacks are. Furthermore, it contains a complete walk-through of how the game for the GoLingual platform was disgned. This includes how the game-play was developed, why the design turned out the way it did, and some technical solutions that made the game possible.

    Incorporating Video Support in an Innovative Communications Solution2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Ericsson is a large actor in the telecom industry, providing infrastructure and communication solutions connecting billions of people around the world. The Multimedia branch of Ericsson focuses on the development of communications solutions, and one of these new innovative solutions is called Cloud Communication. The Cloud Communication system provides an anonymous peer-to-peer communication service through multiple channels. This master thesis is a step to further expand the channels that the system supports as well as rebuild and redesign the applications that make the communication possible. Methodologies that helped achieving this was mainly the design process and to help plan and execute the project Scrum was used. The results of the thesis were added support for video conversations and two entirely new clients supporting the new feature together with the old ones. These new clients can be used to demonstrate the capabilities of the Cloud Communication system and the features it supports. Video conversations in an anonymous context is however questioned and the conclusion is that the video-use case mainly should be applied in a collaboration/business context in which the clients currently are implemented.

    Interaktionsdesign för kommersiella webbtjänster2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The company Microshop is interested in implementing new features in their product-website, and would like to examine the possibility and usefulness of introducing such functionality. When designing interaction for commercial websites, it is important to make the menus easy to use, and refrain from using deep hierarchies in order to avoid causing unnecessary burden for the users. There is an interest among users for adaptive functionality, but this requires great amounts of trust in the website from the user. Something which can be created by refraining from using implicit information, and provide detailed explanations throughout the website. A usability test was conducted in order to complement the data gathered from the theoretical study, the interviews and the expert evaluations. This test evaluated the interface design and the necessity of the proposed functionality. The test was carried out under controlled conditions, and was conducted as a series of user observations of the trial participants. Results showed that there is a need for adaptive functionality, but that the existing interface requires an update before additional functionality is introduced. Proposals on how this could be solved are presented as a number of design proposals which would address the problems, and propose a design for the new features. The usability test proved extremely capable of identifying errors that occurred when the participants corrected their previous actions. In addition, the users trust in the interface, and their previous computer experience contributed to interesting results.

    Points-Of-Interest CollectionGame2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Location-based services often include showing Points-Of-Interest on a map and rely on the availability of geo-contextual data. In Pervasive Games, the players' context can be integrated with the game. Games of this character can be used in order to motivate users to collect Points-Of-Interest. This report describes the process of developing a concept and a working Android prototype where the users can have fun while creating Points-Of-Interest. A concept was developed by following the Design Process as well studying existing games and applications. The main goal of the project was to produce a prototype that is considered enjoyable by the users. The result is an Android prototype where the players can create, check-in, sabotage and upgrade Points-Of-Interest. In order to evaluate the game's perceived enjoyability, the Player Enjoyment Model for Pervasive Games was used. According to the validation of the prototype with the Player Enjoyment Model along with the conclusions from studies of similar applications, the authors believe the game has all the properties essential to an enjoyable game.

    PowerChallenge.com: Monetization and interaction for driving sales2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    If there is still any doubt in your mind that interaction design could help you to more efficiently sell a product on the Internet this paper will convince you otherwise. In the month following the public release of the interface changes suggested in this paper in August 2008 the Internet based sports games company PowerChallenge saw an increase in sales of more than 60% (see results). Using heuristic evaluation and simple user testing the complexity of accessing PowerChallenge's products has been drastically reduced and this has resulted in fewer customers losing their way in the process. Along with slimlining the process of acquiring products the entire web portal has had a graphics remake to make a trustworthy first impression on users. The increased fear of phishing1 and general uncertainty about the safety of online shopping[6] makes many users abandon their intentions of spending money whenever the site drastically changes it's looks in the middle of the payment flow. This has been partially remedied but may require more work. An iterative design process has been applied throughout this project.

    Threat, risk, and vulnerabilityanalyses during the developmentof IT systems in the SwedishArmed Forces2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master’s thesis describes how two models from the Swedish Armed Forces; the risk management model and the IT lifecycle model can be combined. An example is then presented for how the risk management model can be extended for threats, risks, and vulnerabilities related to information technology. The combination and extension of the models are based on a literature study that lists and compares models and methods for threat, risk, andvulnerability analyses, as well as an analysis of threats related to information technology. From the combined and extended model, a design proposal for how to implement the identified functionality was identified. Based on an evaluation that showed that the program NTE and the plugin EASTER were suitable as the foundation for this implementation, the program NTE and the plugin EASTER were extended with further functionality and resulted in the implementation of the plugin ASCENSION. This was evaluated and resulted in ideas for a possible re-design and examples of the future potential of ASCENSION.

    Abstract [en]

    This Master's thesis studies how the technologies of today could be developed to better support education. An analysis is conducted of digital learning tools on the educational technology market. Based on this analysis a conclusion is made that while many other digital tools for education are well suited for their use, only a few computers are designed purely for students. While students in higher education do draw bene ts of using standard laptops and computers in their study work, the students in primary and secondary education should be provided with special learning computers. Therefore a conceptual design is presented for a mobile student computer that helps the students focus on school work.
