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.

The purpose of this thesis is to investigate how Digital Signage systems such as public info kiosks can be designed to better fulfill its main use; to enlighten, encourage and influence the public with information. The challenges presented from earlier studies shows that the public interests and goals, together with proper and relevant content displayed in info kiosks have impact on the attention the public have towards public displays. Qualitative methods such as interviews, usability testing and observations were conducted to further examine how a public info kiosk can be designed to draw attention and grow interest amongst students at K3, Malmo University. Usability testing were used on the digital prototypes that were developed to ensure that the gestural user interface meet the requirements of a proper interaction from the users. Important insights were made concerning; the attention and interest to relevant content, the aspects of the gestural user interface along with the placement of the info kiosk in terms of context.

When a videogame is being played it is rarely a static experience. A videogame can consist of various systems that affect each other in an unpredictable manner which makes the player experience unique for every player.Throughout the years developers of games have used random chance in a games programming to affect the user experience. Sometimes it even goes so far as to having entire games based around the idea of the game itself randomly generating content for a player to experience.This paper will examine randomly generated content in videogames. It will take examples from existing ones and describe how they use it, and reason regarding the benefits and drawbacks of having random chance affect the user experience.The paper will step-by-step examine the purpose of various commonly occurring objects and features of a typical dungeon in an adventure videogame. It will reason around their purpose, and figure out ways to use them in a structured  manner so that we can guarantee that there will be no deadlocks that the player can't overcome.This will range from the environments in rooms, the shape of them, to the objects and creatures that inhabit them, such as locked doors, keys, and bosses.

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.

The communicating home concept has been defined byidentifying the dominating communication technologiesto/from and in the homes, the most important customerbehavior and user needs, the dominating products and thedominating actors of the industry.The evaluation of the communicating home industry has beenperformed with a five forces framework analysis and theoriesregarding value migration and value structures of industries. Ithas been concluded that actors of communication technologies,goods and access services will compete fiercely. The barriersof entry will however be high. When it comes to contentservices the situation is completely different. These actors will,to the largest extent, meet lower competition and low barriersof entry.

The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.

In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

In my study, I have chosen to examine how the user interface and content must conform to design guidelines for responsive design makes it suitable for diverse desktop environment and for varied mobile platforms. The purpose of this study is to examine the extent recommended design guidelines based on scientific research has a positive impact on user performance and perception when using this study delivered hi-fi prototype. The goal of this study is to provide a Hi-Fi prototype with high usability that will introduce and inform the public about BrasilCine according specifications. Study findings from user testing and supplementary questionnaires show that the implemented technologies as design guidelines for responsive design and design features have a positive impact on user performance and perception. The study results are therefore relevant for further prototype development..

Användarskapat innehåll, eller UGC från engelskans User Generated Content, har med teknikens utveckling blivit allt mer populärt på webbtidningar. Det ses som en konkurrensfördel men kan även innebära risker för tidningen, inte minst kostnadsmässigt. Det blir därför viktigt att satsa på UGC som läsarna vill ha, men vad detta innebär är inte ett välutforskat ämne. Denna uppsats ämnar svara på vilket användarskapat innehåll läsare av webbtidningar föredrar, samt varför de föredrar just detta. Med utgångspunkt i en litteraturstudie identifierades fem aspekter som kan hjälpa till att beskriva UGC.

C3LOOPS is an application for DJs and VJs based on surface interaction. A system is said to be based on surface interaction if it presents content on a two dimensional, endless surface that a user navigates through zoom, pan and incremental text filtering where processing is tightly coupled with the content without breaking the workflow. C3LOOPS is designed to encourage improvisation and collaboration. During improvisation changes occur rapidly. Allowing navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up.

As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..

This essay focuses on the term usability while conducting a user centred system design. Usabilitymeans to what extent a user can use a product to achieve effectiveness, efficiency and satisfaction.Development using a user centered system design means that knowledge about the end-users andit?s opinions becomes a crucial part of the development process. The question of this essay is if usinguser centred system design will lead to good usability.We used methods from a user centered system design point of view while developing an applicationfor a Swedish bookstore company called Bokia AB. This included user and task analysis following by aclose relationship between the developers and end-users by using sketches and showing themprototypes of the system while collecting feedback.After concluding our case study we determined that using methods from user centered systemdesign could be used as a great tool to further improve the usability and to improve an applicationssuccess chances..

This thesis contains a usability evaluation of ?Barnplay?, a Swedish video-on-demand service targeted at children. The objective of the study was to identify usability issues in the video service and to develop measures on improving the user interface, with special focus on adaptation to the broad target group of 3-11 year olds.The study was conducted by first mapping established practices in designs of VOD-services targeted at children, followed by interviews and usability tests with children between 2-11 concerning their use of ?Barnplay?. Based on the initial data collection, a prototype was developed and then evaluated by usability testing and A/B-testing.The main conclusion of the study is the need of better individual adjustment of the video content selection to better appeal to different age segments within the target group.

Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

This paper deals with the difficulties of applying user-centered design practices as an independent developer, based on the visualization of a game concept in the form of a prototype. The aim is to evaluate the usability of user-centered design practices, specifically in the field of games development. Throughout this paper, I will give an account of the methods used for testing, as well as a review of previous research done in this field of study. Finally, I will end with a discussion regarding the pros and cons of user-centered design, as well as some thoughts about its importance in similar projects..
