This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.

Man's life has changed in many ways since technology made it?s entry for public at large. In response to this change the science of human-machine interaction was invented. It has in turn evolved into human-computer interaction. With this science the focus is on the customization of the system for the actual person who will use it.The thesis has been implemented in a telecom company's development department.

The aim of this thesis is to describe how service companies through adjustment of the customer?s zone of tolerance can influence customer?s perception of the service during the processes of service delivery and create customer satisfaction. The method used was case study approach utilizing personal interviews, which were conducted at two service companies. The study showed that the aspects of the service that have greatest importance for the customer?s assessment of the service and customer satisfaction among others are personal treatment and that personel behave in the way that makes the customer feel itself taken good care of and unique.

The work related illness has increased and instead of focusing on what?s causing it more and more efforts are put on trying to find the health factors within and outside the work environment. During the past years the term ?long-term health? has arisen; instead of focusing on the number of employees on the sick-list, the focus should be put on the number of employees that has a record of long-term health within an organization, i.e. health-presence.

Målet med den här studien var att undersöka de anställdas känslomässiga bedömning av den interna kommunikationen på ett svenskt skogsbolag med hjälp av en modifierad version av undersökningsverktyget Communication Satisfaction Questionnaire (CSQ) samt två kvalitativa frågor. Studien genomfördes på 65 anställda inom en region av ett svensk skogsbolag. Resultatet visade att de anställda var ganska nöjda eller nöjda med de olika dimensionerna av kommunikationstillfredsställelse samt att ingen statistiskt säkerställd skillnad kunde identifieras mellan tillfredsställelsen hos region- och distriktsanställda. Vidare kunde ett samband påvisas mellan de anställdas arbetstillfredsställelse och kommunikationsdimensionerna: kommunikationseffektivitet, chefsrelation, skvaller och presonlig feedback. Resultatet från de kvalitativa frågorna påvisade att de förbättringsmöjligheter de anställda framhöll främst fanns inom området kommunikationskanaler.

This essay is an investigation of the level- and importance of interactivity on YouTube for the active user. YouTube is a great example of a user-friendly Internet environment which enables the users to take part in a virtual community where they can create the content and, with the various functions the site has to offer, interact with each other. With Uses and Gratifications as a tool for this research we look at the motivations and needs of the user and how they come into play on the most popular video distribution site in the world today. Qualitative interviews on Swedish respondents give us insight in how the YouTube-users with their own words perceive this relatively new highly interactive era. We focus on a narrow group of the most popular age-group of YouTube-users to go deeper - not to expand.

User-centred acquisitions at three academic librariesA new way of developing collections has been adopted at a number of small academic libraries, user-centred acquisitions. The method implies that the main way of building the collection is by means of receiving suggestions of titles from library users. The main purpose of this thesis is to investigate changes in acquisitions of monographs. At a more detailed level it seeks a deeper understanding of what user-centred acquisitions is and how the method effects the acquisitions process. Changes in stock management and the reason why the libraries have chosen the method is investigated as well.

The projects goal was to make an already existing indoor positioning system useful forthe average smartphone user. This was achieved by creating an Android applicationwhich, along with a running server, continuously presents the user with all the currentneeded information. It uses the graphics engine andEngine to create the graphical userinterface. The application was created in the development environments Eclipse andAndroid Studio..

Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.

The purpose of this thesis is to study to what extent the methodological theories are being reflected in the construction of user surveys at public libraries in Sweden. The study has been conducted as a qualitative literature study in two parts. The first part is an examination of literature concerning survey methodology; the second part is a study of three user surveys conducted at Swedish public libraries after 1995. Our main results indicate that the theories about methodology are followed in part, though it cannot be determined whether this is due to any actual methodological studies, common sense, or just copying other surveys. In our study we have found some areas of user survey construction that need further attention and that would benefit from more extensive methodology studies on the part of survey designers.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

The aim of this study was to compare the Query-by-Humming systems Midomi, Musicline and Tunebot regarding their retrieval effectiveness. The aim was to see if there were differences between the systems but also between the user groups common users, musicians and singers. Query-by-Humming system means that the user sings a tune that the system then use to find the right melody.To compare the systems and their users, queries where collected from the different user groups and replayed for the systems. Mean Reciprocal Rank and Friedman test was used to do the comparison.The results showed that the system did not achieve equivalent and that there were no difference between the user groups. The Mean Reciprocal Rank showed that the systems had very different retrieval effectiveness, where Midomi was the system with best result and Musicline with the lowest result..

As a student during my studies, I have been told about entrepreneurs who have red numbers in their financial statements, and there is a forest machine operator shortage in Sweden. The basic idea of this thesis was to examine the underlying factors that may have caused the problems described above. The aim of this thesis was to investigate the factors that create stress and job satisfaction as a forest machine operator. The study was performed as a comparison between forest companies own harvesting teams and entrepreneur teams to investigate if there are any differences in stress and job satisfaction between the two different types of team. The study was conducted in collaboration with SCA Skog. The material for this study was collected by doing interviews with SCA's harvesting teams. A total of 27 forest machine operators were interviewed, divided into a total of 10 separate harvesting teams. It was very similar between the different type of teams, which situations the operators experienced stress.

This essay explores to what extent the Swedish language version of Google Images meets the usability requirements of average everyday users. Previously published studies on user behaviour and users? interface and search option preferences define the usability requirements, which are matched against Google Images? actual interface and search options. The retrieval method of Google Images is also briefly discussed, and users? opinions about Google Images too, as they come across in the previously published user studies.The findings are that Google Images lack some of the things that users ask for, but it still seems to be the most used image search engine among average internet users and more appreciated than other search engines.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.
