This study investigated how banner ads, depending on its quality and placement,can capture a user's attention while searching for editorial content in an online newspaper. Furthermore, the user's search strategy was also studied to see whether it varied depending on the placement of an ad. An experiment was conducted where 20 subjects searched for articles in a Swedish online newspaper while their eye ovement was recorded with a headmounted eye?tracker. In each search task the online newspaper contained either a low quality ad or a high quality ad.

Most often when developing a new system there is a need get a functioning testtool up and running. Including time, cost and resources the solution isn?t always obvious, developing your own or buy one ?of the shelf?. The purpose of this thesis is to study how a general testtool for executing functional tests should be designed to be reusable, be based on recognized knowledge and be able to fast and simple be customized for different types of systems. Key functions from the litterature is presented and used in the design of a testtool prototype.

Målet med denna rapport är att ta reda på hur lång en attackanimation i ett spel kan vara innan spelaren blir frustrerad över att den tar lång tid. Forskningen inom dataspelsutveckling är fortfarande begränsad, men det finns mycket att hämta från området Human-Computer Interaction. Undersökningen genomfördes på 22 personer med spelvana. De fick spela en av två versioner av ett fightingspel som utvecklats speciellt för undersökningen, sedan fick de svara på en enkät om hur de upplevde spelet och attackerna. Deras knapptryckningar under spelandet loggades.

BCI (Brain Computer Interface) för användning i spel har börjat dyka upp på konsument-marknaden. Dessa använder ofta EEG för att mäta spelarnas avslappningsnivåer och den spelare som lyckas nå högsta meditativa tillstånd samlar poäng. I detta arbete undersöks huruvida det går att använda BCI för mer direkt kontroll av en specifik spelmekanik i kombination med konventionella spelkontroller. För undersökningen har två versioner av ett spel skapats med avsikten att mäta skillnaden i hjärnaktiviteten hos spelare som bara spelar, jämfört med spelare som aktivt försöker åstadkomma ett specifikt sinnestillstånd för att direkt kontrollera en funktion i spelet. På grund av studiens begränsade omfattning kunde inga definitiva slutsatser dras men det finns indikationer på att MindWave, som var utrustningen som användes i denna studie, inte är lämplig som direkt kontrollmetod tillsammans med andra kontroller.

Problem: Our opinion is that it is important to consider about usability in system development. In this thesis we will focus on usability in point-of-sale systems. The point-of-sale system we base this thesis on is Extenda Retail. Our case study is performed on Ica Kvantum in Bromölla, which implemented Extenda Retail about two years ago. Purpose: The purpose of this thesis is to figure out what important factors there are to consider, in usability aspects, when developing point-of-sale systems, with focus on the cashier. We also wish to find out the cashiers opinions about the Extenda Retail system. Method: The information gathered for this thesis consists of literature and interviews.

This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to implement. Because of this, the text aims at providing a solid foundation of the mathematics needed, at explaining in greater detail the steps needed to solve the problem, and lastly at improving some aspects of the animation process as it has been described in earlier works. The aim of the system itself is to provide visually plausible renditions of animated fluids in three dimensions in a manner that allows it to be usable in a visual effects production context. The novel features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities..

In this paper we have studied how young adults read news on the internet. The purpose was to seehow the consumers of news were irritated by the adverts on news sites depending on whichplatform they used, a computer or an portable reading device of the brand Apple iPad. Observationsand surveys were conducted on ten people. The news sites we used for this study were www.SvD.seand www.expressen.se. The result show that a majority experienced that their news consumptionwere irritated by advertising, mostly on Expressen's news site because it wasn't perceived asforeseeable..

Dagens digitala spel är oerhört komplexa produktioner som ofta kräver en multitud av  sofistikerade verktyg för att förverkligas. Ett intrikat nätverk av moderna lösningar där såväl  visuella som audiovisuella element samverkar för att frambringa fängslande och entusiasmerande  upplevelser är vad som gör dagens spelproduktioner, och ingen annan bransch har sett samma  raketutveckling som spelbranschen sedan dess begynnelse. Ljuddesignens roll i digitala spel har  dock förblivit passiv där andra element tagit an mer dynamiska roller i varierande form.  Generellt sett är ljudet oftast mer ett komplement till de visuella elementen än ett fristående  förmedlingsredskap. Då audiovisuell kommunikation ej delar vissa av de begränsningar som  visuell kommunikation innehar, såsom grafisk processeringskraft, bildskärmsavgränsningar etc,  så ser vi att ljuddesign besitter en stor mängd outnyttjad potential som i teorin hade kunnat  förgylla spelupplevelser kolossalt.Det här arbetet undersöker både genom analoga och digitala medel hur införandet av binaural  lyssning i spelproduktioner kan förbättra navigationsförutsättningarna för användaren avsevärt  då djup och höjd kan skildras mycket mer effektivt, samt hur dess applicering i tredimensionella  miljöer kan främja såväl nöjes­ som lärosyften i så kallade Audio based Environment Simulators  (AbES).

There are a huge number of books and articles written in the field of usability and about the art of giving the user the opportunity to find the information he is trying to reach while browsing the website. The writers of these books are handling guidelines that are recommended to be followed, as well as describing their own views, ideas and theories of the subject. We found an interest to research the different possibilities, if any, to develop a website optimal for the user from a usability point of view. Another thing we noticed was that a need of a substantial guidance existed in website development aimed for recently started companies.New theories and rules regarding usability, which are seen as superior to the old ones and therefore replaces them, is not created that often. This is different from other IT related subjects.

The aim of this thesis was twofold, on the one hand to compile a set of usability and accessibility guidelines in order to establish the characteristics of a user friendly website, and on the other to test these guidelines on eight library webcourses with user education to see how well they adhered to the guidelines. The methods used were literature survey and source studies. The guidelines found in the literature survey were divided into four different categories: document properties, structure and navigability, visual characteristics and accessibility. In order to establish the adequacy of the guidelines, I examined reference sources, mostly on the web. To a certain extent this examination has been based on HCI Human-Computer interaction theories.

Firewalls protect network traffic and decide witch traffic to send further and witch traffic will be blocked. All this depends on the rules in the firewall. The firewall is installed between the internal network and the Internet. It is difficult to find a firewall that can protect us against different threats. Firewalls have both advantages and disadvantages and all this make them vulnerable.

Studien grundar sig i ett intresse för hur barn interagerar med datorspel. Datorer och datorspel blir mer och mer vanliga i barnens omvärld. Syftet med studien är att belysa och beskriva hur barn i fem års åldern gör när de spelar ett datorspel och hur de interagerar med det. Vi belyser bland annat hur barnen tolkar ikoner, hur de förstår den auditiva informationen i kombination med bilderna, och vilka strategier de använder för att ta sig vidare i spelet. Vi studerar också vad de minns när de spelar spelet för andra gången.

The aim of this paper is to elucidate and analyze history teacher's didactic choices in the conflict between unequal educational materials and the requirements of equality in the curriculum of Swedish secondary school. The empirical data consists of interviews with five secondary school history teachers, observations of their lessons as well as analysis of their tests. The starting point was to investigate teachers' didactic work in the role as a bridge between the non-equal historiography presented in textbooks in history and the curriculum?s demands for equality. Three different approaches have been observed in the teachers' didactic work when considering gender perspective into their teaching: that women become extensions in a male-dominated historiography; that another part of the story is presented when a gender perspective is considered; and that the gender perspective is included in history teaching and becomes an integral part of all the content of the subject.Several of the teachers acknowledged that gender equality is less prioritized than the courses core content and related assessment criteria.

The purpose of my study is to examine why five primary school teachers chose to start using the method ?Learning reading by writing on computer? in their teaching. How do they perceive that the method works in their classroom and do they perceive that the method affect the children?s literacy?The study consists of a qualitative method in form of interviews with five primary school teachers and also some observations made by me in the classrooms. I will use the findings I made during the interviews and observations and contrast these to relevant literature and research that I have collected.The result of my study shows that all of the interviewed teachers had a self-interest in working with the method ?Learning reading by writing on computers? and that they also worked closely with colleagues.

SWITCH- Swedish Intelligibility test for children, is a test thatmeasures intelligibility of children's speech through repetition of singlewords. The test is computer generated and consists of 1000 word listsrandomly selected for each assessment. The purpose of this study was toexamine the equivalence, reliability and validity in the word lists. Word listswere tested on ten children with typical language development (N group)and ten children with speech deviation (T group). The children were audiorecorded when they repeated two lists.
