Mätning av Tidens Inverkan på Användarupplevelsen : En Fallstudie
Det finns i dagsläget få tids- och kostnadseffektiva metoder och tekniker för att mäta och utvärdera användarupplevelse över tid. Detta trots att tidsaspekten av användarupplevelsen under de senaste åren har uppmärksammats som en viktig komponent av användarupplevelsen inom människa-dator-interaktionsforskning. UX Curve och iScale är två metoder framtagna för att mäta förändringar i användarupplevelse över tid med hjälp av retrospektion och skapande av grafer över utvecklingen av användarupplevelsens olika dimensioner.Mot bakgrund av dessa metoder togs ett webbaserat utvärderingsverktyg fram med målet att undersöka verktygets förmåga att mäta förändringar i användarupplevelse under en utvärderingsperiod. Verktyget testades på 9 deltagare i en utvärdering av en mailklient under två veckors tid.Resultatet indikerar att utvärderingsverktygets dimensioner samlar upplevelser av relevans för de dimensioner som undersökts men visar också på att ytterligare testning och validering av metod och verktyg behövs för att fastställa att mätningarna är reliabla och att det som mäts är vad som avses mätas..
Användarundervisning på webben design för lättillgänglighet och användbarhet
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.
Optimerad bildsökning ? Bör vissa egenskaper prioriteras vid sökning efter en viss kategori av bilder?
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..
En undersökning i datasäkerhet för hemanvändare - Är det nödvändigt att använda brandvägg?
The emphasize of this study is to evaluate security issues for home users
having a personal computer connected to the Internet. It focus on the usage of
advantages and disadvantages when using a firewall while connected to the
Internet.
The hypothesis is that it gives a better protection to install and use a
firewall compared not to do so, due to security flaws in the operating system.
The prediction was tested on a home user's personal computer. The testwork was
divided into two major tests, each of them performed with, respectively
without, a firewall. These major tests were divided into five smaller semi
tests. The first semitest without a firewall suffered from a virus or worm
attack resulting in loss of data and log files.
Användare och användning : av information och handlingar i moderna polisorganisationer
This study examines use and users of information and records originating in the context of a contemporary police organisation. This area of research has only been of focus for a relatively few researchers. This in contrast to use and users of historical archives which has been in centre for more studies. The study is conducted with a quantitative method structuring data from 120 selected registered matters containing user queries. The research questions addressed are:- what user categories use the records of the authority- which are the ways of contacting the authority preferred by the users- which are the identifiers provided by the users and how well are they matched by the search artefacts available to the staff of the authority- what information and records are sought-after by the users.For comparing the identifiers provided to the search artefacts has been selected the two most frequently used registry systems within the authority.

Bibliotekariers pedagogiska roll: Om konsten att lära andra att söka och använda information
There is an increasing demand for information literacy, which is mirrored in curriculum throughout the whole educational system. This, in turn, has brought forward a growing need for librarians who can teach. But do librarians possess pedagogical competence, and if they do, how is this ability used in everyday library practice? The aim of this study is to investigate librarians' conceptions of the pedagogical role, as it is expressed in their didactic interaction with the users. The research questions focus on librarians' experiences of teaching information seeking and use and their activities in this respect.
"Jaha, nu har en halv miljon människor varit inne och tittat på fisken" : Journalisters tankar om att anpassa sig efter klick
Computational techniques have transformed the journalistic approach. Journalists now have the opportunity to integrate user-statistics from the news website with their work. Singer (2011) argues that journalists seem particularly afraid of items, which they perceive as trivial or otherwise unsavory, will prove popular - potentially creating management pressures to produce more of those stories. She describes this practice as ??traffic whoring??.
Skönlitteratur, inköp och folkbibliotek ? en kvalitativ ansats
The aim of this thesis is to examine the Swedish public libraries acquisition processes when it comes to fiction for adults. The thesis focus on how the librarians responsible for acquiring view literary quality when they manage their collections and how their views coincide with that of the user?s explicit wishes. Furthermore this thesis looks at the librarians reading habits and how they coincide with that of their perceived users.The study uses literature pedagogic perspective theory to see how the librarians look at fiction and what they value in it. In order to get answers six librarians have been interviewed in this study that uses a qualitative approach to getting answers.
Hylluppställning i förändring ? En studie över svenska folkbiblioteks alternativa hylluppställningar
The aim of this thesis is to study how public libraries in Sweden use alternative shelf arrangements that differ from the library?s original classification system, which in Swedish public libraries usually is the SAB-system. I sent out a survey to 169 public libraries, where I received 114 replies. 77 of these stated that they had some kind of alternative shelf arrangement, therefore these are the ones that are included in my study. I wanted to investigate in what way the libraries had changed their shelf arrangement and why this decision was made.
Högskolestudenters upplevelser av folkbibliotekariers bemötande och kunskap
The aim of this Master's thesis is to understand public library users' perceptions of librarians' attitudes to users and professional knowledge. The purpose was also to investigate the relative importance to the user of pleasant or a knowledgeable librarian. As a theoretical framework we use theory from business economy where the experience of the user is in focus. Answers were sought to the following questions: How do users perceive librarians attitudes to users? How do users perceive librarians professional knowledge? How do users want to be treated by public librarians? What kind of knowledge should public librarians have, according to users? We interviewed twelve students in university education that are users of public libraries.
Smarta Hus: Nya behov och lösningar med participativ design
In this Bachelor Thesis (20 p.), we present the history and development of
"Intelligent Houses", and most important- explore some of the future
possibilities in this area.
The project has been carried out through an interdisciplinary cooperation
between three different educations at the Blekinge Institute of Technology.
By conducting a dialogue with various actors with different professions, we
have been trying to identify needs within the concept of "Intelligent Houses",
were the end user is not only the tenant or homeowner.
Through Participatory Design methods, such as a Future Workshop, we have
brought the users together to discuss their own and each others needs and
hindrances in their respective work practice, and how intelligent house
technology could improve their work conditions.
We have also been testing a highly sophisticated
CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally
developed for regulating indoor climate systems.
Based on the needs we have found in our fieldwork, we have been looking at
possibilities to make multi user solutions with the sensor..
Lokaliseringsbaserade tjänster : En användar- och kontextcentrerad kartläggning av LBS
Location-based services (LBS) contains of services helping users of finding positions of themselves or other objects. LBS applications can present information in varies types of ways, these could be threw speech, text, geographic symbols, photos etc. Not many studies have been done to examine the aspects of LBS communication and there is a demand for user and context centered mapping.The purpose of this report is to present a model for the development of user and context based services. The model will give guide lines of recommendations when implementing LBS. The different technologies that support LBS will also be noticed.
Simulator för el- och värmeproduktion : påverkan på ekonomi och miljö
In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely.
The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished
the result is graded in the following categories: economy, environment and quality.
To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.
Automatiskt Nödstopp
In today?s industry it is starting to get more and more interesting with wireless systems and solutions for applications. To be able to reduce the amount of cables drawn to various machines which takes both space and an extra fee for every cable drawn. Some systems might require the user to use a handheld device that is directly connected by a cable which in some machines might be inelegant for the user.The goal with this bachelor thesis is to develop wireless monitoring of the machine operators position that is working with heavy industrial machinery. The thesis started out with researching different techniques for positioning a transmitter indoors, this was done in order to get a better understanding on how to go about.
