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.

This paper reports a study on the usability of e-commerce accessed through smartphones. There is much research in the usability of mobile interfaces and many sets of design patterns have been created but a few studies are available for specific domains, and in this report we focus on mobile e-commerce. In this study a framework is developed for how to design mobile e-commerce interfaces with a high degree of usability. Furthermore, the study also contributes a method to how other specific domain can develop a framework with general standards to work from when creating a web interface. By examining two sets of design principles and 14 design patterns, we evaluate which ones are critical in the design of a mobile e-commerce interface for achieving a high degree of usability.

The outset of this thesis is to raise questions on how we design for the mobile context and the capabilities of smartphones. Not only the presentation but also the use of input and interaction between a service and a user.This work evolves around sign up forms and answers the question: How does the sign up process affect the holistic perspective of a digital service regarding usability and user experience? This thesis consists of a case studies, and design experiments conducted on Twitter, Instagram and Randos sign up processes to explore if and how the usability, and the user experience could be affected and im- proved.This concluded some important aspects to be considered when designing sign up forms for a digital service.The usability, and the user experience is not only affected by user interaction, and the choice of input method but it?s also affected by which data the service is requesting, and more important; if that data is motivated to request by the service..

This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II interface development easier, a car simulator was first built. Both the car simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface.

The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.

AbstractThis study examines the technologies appropriate in developing back-and solutions for search-driven user interfaces of e-commerce sites. The study is based on existing research in search-driven user interfaces of e-commerce sites from a design point of view, but instead the focus of this study lies within a back-end perspective. This choice of focus is a result of the gap that was encountered within research and other literature when it comes to general advice in how e-commerce sites best should build back-end solutions to support search driven user interfaces. The technologies that have been examined and compared are traditional relational databse management systems (RDMS) and the newer so called No-SQL database management systems, and also traditional search engines and the newer variant s of search engines. The study concludes that in some cases it is appropriate to combine traditional and newer technologies when it comes to databases, while the comparison of search engines indicates that there are some newer search en gines that have the ability to meet more of the needs that can be identified on the back-end solutions.Primary data consists of interviews made ?face to face? with experts on the subject and questionnaires addressed to selected e-commerce companies via e-mail.

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

In industries today the demand for reading the state of industrial equipment and thus prevent machine breakdown, is increasing. The company HMS Industrial Networks AB has a product on the market, Netbiter EC350 that is used to read sensors and thus find out the condition of industrial equipment. By reporting scanned data to users through a cloud service, users can keep track of their equipment. When developing Netbiter EC350 a slot was made for a Bluetooth module to offer clients a wireless reading in future developments. In this project a prototype was made to show how this Bluetooth communication can be implemented. The goal of the project was to create a Bluetooth communication between a Bluetooth sensor and Netbiter EC350. A user interface was made to allow the user to read sensor values. The result of the project shows how a Bluetooth communication can be implemented to read sensors wireless and therefore it fulfills its purpose and goal.

There is a lack of published material regarding designing Graphical user interfaces of so called integrated video uploading services. The term integrated video uploading services refers to homepages that do not have video uploading as its primary purpose but which still offers that service to its visitors. The aim of this thesis was to improve the amount of published material about designing Graphical user interfaces for integrated video uploading services. This was done by performing a literature study to find general design guidelines which can be applied to design of integrated video uploading services. Thereafter the functionality and design of dedicated video uploading services was analyzed.

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.

When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.
