Ever since the development of the pc and their software, in the early 80´s,architects way of work have changed a lot. Nowadays most of the architectspresent all their works digitally and not with hand drawn material, as they didbefore the pc boom.Digital visualisation technique pushes the limits, when it is about presentingarchitecture projects Virtual reality.This report studies how digital visualization technique is used among thearchitects today.Together with architects from ABAKO architect firm in Gothenburg, Sweden,interviews has been made to give answers about what they think about digitalvisualization technique. What are the opportunities, advantages- anddisadvantage with this digital technique?The answers from the architects, together with work that has been done withdigital visualization technique in a project called Project Sofiedal, shows thatthis technique has big opportunities when it comes to create nice looking VRpresentations. The result in this report also shows that this digital technique ismore time demanding compared to hand drawn presentations.The investigation shows that digital visualization technique is a goodcompliment when it is about showing the citizens how future projects willaffect the surrounding.
Den Digitala teknikens påverkan på resebranschen och dess marknadsföring
The intention of this essay has been to investigate how the new digital technology has affected the tourism industry and marketing, as well as how travel agents and tour operators adapt to this. We also aimed to get a broader view of how the future might look like when it comes to marketing and virtual service landscapes. We decided to base our research according to these following four questions:? What affect travel agents? way of adoption to the technical development?? What purposes do the travel agents have for building up their virtual service landscape?? How much does the travel agents emphasize on digital marketing?? What can travel agents do to better adapt to the technological development in the future?We have chosen to use a qualitative research for this essay. The reason for choosing a qualitative research was to gain a wider understanding that would represent a big part of the changes of technology development.
Metodik för utmattningsberäkning av svets i vibrationsmiljö
In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

Datorer i språkundervisningen i engelska : En jämförelse mellan teori och verklighet
AbstractThe purpose of this paper is to compare existing theories and policies on CALL (Computer Assisted Language Learning) with the actual situation among practising teachers of ESL (English as a Second Language) of secondary schools in Sweden. The evaluation focuses on the differences between theories and reality, and discusses why, if any, the differences exist. Some background information on second language acquisition is provided, and recent theories and standpoints within the field of CALL are mentioned to highlight the differences between theory and reality. The evaluation was made by handing out a survey to 33 teachers of ESL, asking questions about their use of computers in their everyday teaching. The survey shows that the gap between the theories and standpoints within the field of CALL, and the reality of teachers in schools often is huge.
Stadsrum representerade i VR : Examensarbete i Informationsdesign med inriktning mot Rumslig gestaltning
Detta är ett examensarbete inom informationsdesign med inriktning mot rumslig gestaltning. Syftet med min undersökning var att ta reda på hur ett kvarter i Eskilstuna kan formges till Virtual reality (VR)-mediet, så att det går att få en upplevelse av hur en stadsplanering skulle kunna se ut om den genomfördes i verkligheten. Resultatet från min studie är grundat på, prototyping, intervjuer, och en enkät. Min undersökning visade att för att det ska gå att få en upplevelse av ett stadsrums utseende efter en nybyggnation, bör representationen formges efter tänkt målgrupp och budskap. Felaktiga eller för många informationsgivande detaljer kan leda till att fokus hamnar på information som inte är nödvändig, eller till och med felaktig, för att förstå hur kvarteret kan komma att se ut efter en nybyggnation. För lite information om olika detaljer eller för låg detaljrikedom kan leda till att representationen blir svårtolkad. Min undersökning visade också att visuella detaljer som är svåra att formge, bör kompletteras med t.ex.
Bibblan svarar ? ett tecken i tiden : En virtuell referenstjänst ur ett postmodernt perspektiv
The aim of this master?s thesis is to examine the virtual reference service Ask the Library [Bibblan svarar] from a postmodern perspective. Ask the Library is a Swedish online reference service that is run by the country?s public libraries. The postmodern theories of Jean-François Lyotard are used to study how information is managed and transmitted within the service.

The area may take any form and should be scalable up to and including national borders. The enclosure is managed on the mobile unit. The target system is Android. Smartphones, tablets and more recently, cameras is examples of mobile units.
Närhet och distans i det virtuella referenssamtalet. En studie av Fråga bibliotekets chattfunktion.
The purpose of this study was to investigate the levels of social distance used by the librarians and users in the virtual reference interview. With a conversational analysis and applied politeness theory 49 chat transcripts where analysed in order to answer the question of how the interlocutors positioned themselves regarding the social distance between them. By identifying what communicative strategies where used the following results were found. Generally the social distance between librarians and users is low in the Swedish virtual reference interview. Even though both parties used informal and casual language the results indicate that the librarians face wants were valued slightly higher than the users which were illustrated by a some what higher social distance in the stages of the conversations when the librarians face was under most threat.
Jämförelse av olika presentationsteknikers inverkan på precisionsbedömningar gällande avstånd i virtuella och verkliga miljöer
Denna rapport behandlar skillnader i bland annat visuell information (som olika djupledtrådar) vilka kan ha betydelse för den visuella upplevelsen och inverkan på till exempel precisionsbedömningar gällande avstånd i både virtuella och verkliga miljöer.Rapporten lyfter fram tre olika presentationstekniker som presenterar visuell information i olika utsträckning. Två av presentationsteknikerna, Desktop och CUBE, presenterar två virtuella miljöer. Den tredje presentationstekniken, Verklig, presenterar en verklig miljö. De tre presentationsteknikerna ställs mot varandra i en undersökning gällande eventuella skillnader i precisionsbedömningar (avståndsbedömningar mellan och på olika objekt). Resultatet visar att det föreligger signifikanta skillnader vad gäller precisionsbedömningar mellan den virtuella presentationstekniken Desktop och Verklig samt mellan den virtuella presentationstekniken CUBE och Verklig.
Virtuella vävnadsobjekt för medicinska träningsapplikationer
This Master thesis discusses the development of a virtual human soft tissue object for use in exercise applications of various medical procedures.The soft tissue object to be developed shall look like, feel like and behave as living human tissue. It shall give the user a realistic feeling of weight, softness and roughness, and shall behave in a correct way for exercise purposes. The soft tissue model is to be used in a three dimensional stereo graphic environment with haptic feedback. A prototype for practicing the procedure of inserting a catheter is built. The prototype is used to evaluate the potential of the virtual environment for medical exercise applications, and to assess the realism and usability of the soft tissue object.
Steg mot Informationsvisualisering med Augmented Reality
Som en del av forskningsprojektet Young Operator 2020 så syftar den här studien till att vara ett första steg mot en produkt, som med hjälp av av tekniken augmented reality ska vara en del av framtidens tillverkningsindustri. Studien utgår från kognitionsvetenskap och människa-datorinteraktion för att ha användaren och användarens interaktion med prototypen i fokus. Eftersom olika typer av användare kan behöva olika saker av ett system, kommer den här studien också att utgå från teorier om kompetensnivåer. Ett system som är användbart för exempelvis en novis behöver inte nödvändigtvis vara användbart för en expert. En prototyp har skapats som en del av ett annat projekt och den utgår från det arbetssätt som operatörer på Volvo GTO i Skövde har idag.
Augmented Reality i mobiltelefonen : En kunskapssammanställning med trafikinriktning
This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.

Off-Shore Blackboxing & Global Software Development : En studie av utmaningar och möjligheter med distribuerad systemförvaltning
Global Software Development (GSD) is based on a geographical distance where teams are spread throughout the world. The related research have for a long time addressed the challenges presented by geographical distances. GSD is basically a necessity for many businesses to use in order to reduce development costs, reduce production time and to maintain high quality. The study aims to investigate the relationship between the reality of a specific maintenance project. Thus, our research question: How do distributed maintenance teams experience temporal, geographical and socio-cultural distances? To achieve the purpose of the study, we chose to perform a case study of a global consulting company which recently started a new system maintenance project.
