Portable IT devices such as laptops, smart phones and computer tablets are becoming ever more ubiquitous. At the same time, the population of the Western world is growing older, with aging bringing about changes with regards to individuals' physical and mental capabilities. These facts raises important questions about how well suited these devices are for use by elderly people. This study focuses on the cognitive aspects of the devices' usability, using the concept of mental models to analyze the users' understanding of a computer tablet. It also draws upon theory of graphical user interfaces in its analyses.

A degree project has been carried out at Motion Control, Västerås. The degreeproject ?Grafisk Skärm för Inbyggda System? have developed a first prototype of anembedded system with a display, a graphical user interface with touchscreen andpossibilities to communicate with external units.The work initiated with surveys of critical components. A technical specification forthe desired end product was developed. With the technical specification as support,design specifications for hardware and firmware were developed.After the specifications were done, a circuit diagram was developed and a circuitboard was made.

IT utgör en stor del av majoriteten av folks vardagliga liv. Smartphones och surfplattor har om möjligt ytterligare ökat vår användning av tekniska enheter och prylar på en daglig basis. Arbetet tas med hem i en större grad med hjälp av laptops, VPN och molnmöjligheter. Mail kan tas emot i princip var och närsomhelst på dygnet. Men hur bra är säkerheten? På arbetsplatsen hanteras mycket av IT-säkerheten och ansvaret för den ofta av erfarna och dedikerade anställda, men hur ser det ut hemma där användaren själv har ansvaret för sin IT-säkerhet?I denna studie analyseras och identifieras risker och problem vid hantering av olika aktiviteter relaterade till IT-säkerhet i hemmet.

Service Design is a relatively new, unexplored and exciting phenomenon that through an interdisciplinary work methodology designs services. A discussion has been going on for a long time regarding whether there is a difference between products and services. Services are often classified as immaterial, heterogeneous, non-storable and inseparable in relation to products. A question that arises is if something specific characterises the work methodology used regarding service design. The aim with this paper is thus to explain the work methodology when working with service design.

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security.

The popularity of video games has been boosted by the rise of user-generated live streaming platforms, and the biggest of them all is Twitch. The popularity depends on Twitch alignment of live streamed video games. The stream is created by a player who broadcast and streams the video game online. The video game can then be watched by a viewer that is interested in the video game. In every stream there is an implemented live chat that allows the viewer to interact with the streamer while the stream is online.

TeliaSonera har sedan ett tag tillbaka inlett ett projekt med ett antal företag inom byggbranschen. Projektet går ut på att ta fram kontrolltekniker som kontinuerligt mäter en byggnads tillstånd genom hela dess livstid, så att eventuella brister kan upptäckas innan de blir till ett problem. Med andra ord är tanken att ha någon form av teknik som kontinuerligt avläser diverse egenskaper i en byggnad som exempelvis fuktighetshalten i väggarna, om ventilationen fungerar som den ska och halten av olika ämnen i luften.Det praktiska syftet var att verifiera om trenden kontinuerlig kontrollmätning efterfrågas genom att ta kontakt med branschexperter inom såväl byggbranschen som vissa andra parallella branscher och se om även de uppmärksammat denna. Under antagandet att de gjort det, var intentionen vidare att försöka urskilja de så kallade lead users. Lead users är användare vilka erfar behov före marknaden som helhet samt som är benägna till att vara innovativa, då en lösning på deras behov förväntas medföra stor nytta för dem.

This thesis investigates in which way principles and theories of usability is revelant when evaluating interactive systems for children aged 10-12. It also investigates whether there are specific factors that you should keep in mind while developing interactive products for the targeted group.The results of the qualitative study shows that priciples and theories of usability is relevant when evaluating interactive systems for the targeted group. However there is one concept that is more significant than the others. Our study shows that our targeted group is sensitive to time-consuming activities such as loading times etc. which has to do with the efficiency of the system.

This thesis evaluates the user board of the elememtary school in Veberöd, Sweden. In this process an evaluation model is developed. The model itself gets evaluated in a meta-evaluation to improve the model for future use.The starting point of the evaluation is the deliberative democracy theory. Although Sweden is a representative democracy an official desire exists to have a democracy with deliberative qualities. The evaluation model is constructed to fit this context and is therefore, not only, set out from classical goal-based evaluation but also from deliberative democratic evaluation.

With the new generation of smartphones the boundaries for what is a mobile phone and whatis a computer becomes more subtle. 2009 the shipment of smartphones with touchscreen morethan double the 2008 figure and the total amount of smartphones is now over 10 % of the totalworldwide shipments of mobile phones. There?s still one problem to solve and that is the lackof web content specifically adapted for smartphones.The purpose of this paper is to identify and analyze from a user and usability perspective howto make a successful migration and design of a user interface for an existing web basedsystem so that it also fit smartphones.The paper starts with a theoretical reference material containing examples of differentapproaches for design and migration of an interface.A case study is performed and prototypes are designed with support from guidelines andrecommendations in the theory part.The conclusion stipulates that in the present situation there are no shortcuts when it comes tomigration of an existing web based system for the mobile web. The recommendation is aspecific interface for each different unit that are going to interact with the system.Research that analyzes differences between all mobile web browsers would be of greatinterest, a research that hopefully leads to guidelines for what level of mobile web standardthey should at least support.

The aim of this Master thesis is to make a survey of the public library staff-relations at work and discuss relationship marketing as it applies to public libraries. Relationship marketing involves the establishment, maintenance and development of users and other library-related relationships, including the relations among the library staff itself. Good relations among the library staff is a necessary condition for good relations with others. The focus of relationship marketing is at the user?s needs, wants and demands instead of the library collections and services.

This thesis treats a new perspective in the theory of classification, the context-based approach. The aim is to find out what kind of value this new approach can have in the process of creating a classification scheme for a special library collection. The first question to be answered is how the context-based approach works in a real life. The second question investigates which role the research in this particular area might have. Illustrating a real-life situation, the unit of Rättsmedicinalverket in Linköping serves as the object of study.
