My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

When searching for better and more practical interfaces between users and their computers, additional or alternative modes of communication between the two parties would be of great use. This thesis handles the possibilities of using eye and head movements as well as voice input as these alternative modes of communication. One part of this project is devoted to find possible interaction techniques when navigating in a computer interface with movements of the eye or the head. The result of this part is four different controls of an interface, adapted to suit this kind of navigation, combined together in a demo application. Another part of the project is devoted to the development of an application, with voice control as primary input method.

Galna Glassen is a company that has a unique way of selling ice cream in Sweden. The idea is for the costumer to be able to compose their own favorite ice cream, partly by choosing the flavor of ice cream but also by picking the ingredients. The ingredients that can be chosen from are around twenty and can be everything from cookies to candy to berries. When the costumer has chosen their ice cream and ingredients they are mixed together on a cooled granite board.The company was very successful when it was founded in the summer of 2011 and decided to expand to other cities in Sweden. They also wanted to explore the profitability of a mobile sales unit that is intended for festivals and events.The thesis is meant to develop Galna Glassen?s mobile sales unit.

Ericsson Mobile Communications AB (ECS) i Kumla producerar mobiltelefoner, främst digitala mobiltelefoner. Produktionsenheten ytmontage producerar idag kretskort baserade på prognos erhållen ifrån slutmontage som slutmonterar den färdiga telefonen. Problem har dock uppstått efter införandet av Build To Order (BTO), detta innebär en utvidgning av synen på att producera en telefon mot kundorder. Prognosen tar dock inte hänsyn till slumpmässiga fluktuationer, vilket innebär ojämn produktionstakt samt ökad belastning på personalen inom ytmontage. Problemen förvärras ytterligare genom att vissa kretskort ska produceras hos legoleverantörer.

I detta arbete har vi studerat tjänsten SMS-betalning. Vi har fokuserat på att utvärdera och beskriva tjänstens användningsområde samt dess styrkor och svagheter. Utifrån företaget Mobill, vars affärsidé är att utveckla en betalningstjänst via SMS har vi fått en bild av hur ett företag kan satsa på denna teknik. I en studie med konsumenterna har vi visat den generella bilden av inställningen till betalningstjänsten, detta för att vidare kunna utvärdera betalningssystemet. Dessa studier har båda en kvalitativ karaktär.

The purpose of this thesis is to create opportunities for an efficient interchange of information between humans and technology, especially for the skilled user, and put the designprincipal for informative structures and features into practice. Informative structures and features in a large number of information items helps the peripheral visual system to automatically capture knowledge through logical patterns.A field experiment was done to evaluate if informative structures and features, implicate efficient human information-processing, even in a small study. The results was ambiguous because the quantitative part of the investigation didn?t show any significant differences, whereas the qualitative showed that people prefer a dynamic document with a high degree of informative structures and features over a dynamic document with a low degree of informative structures and features. Even if this study was inconsistent, probably because to few subjects where used, the implication of the research that?s behind it is solid.

Ibyggbranschen i Sverige idag strävas det efter att fortsätta utvecklingen av eneffektivisering gällande miljö, kvalitet och styrning.Samhället och byggbranchen har utvecklats och digitaliserats enormt de senasteåren, dock har vissa mindre delområden avstannat och det är bland annatdigitala metoder för arbetsordrar och registrering bland hantverkare.  Studien som är gjord syftar därför till att undersöka ifall det går atteffektivisera och digitalisera metoder gällande arbetsordrar och registrering.Uppsatsen syftar till att undersöka ifall det går att effektivisera styrningen,miljöpåverkan, kvaliteten och ekonomiska delar bland byggföretag med hjälp aven mobil applikationslösning.I studien har jag valt att använda mig utav teori gällande miljö, kvalitet,styrning och finansiering där jag fördjupat mig i delar som är påverkningsbarmed hjälp av ett digitalt verktyg i form av en mobil applikation och dessfunktioner.För ett införande av applikationslösningen krävs det en invänjning och enmotivation ifrån hantverkarna eftersom att det innebär en stor förändringjämfört med den manuella metoden som använts under en längre tidsperiod. Detframgår att arbetsbelastningen för vissa delar i arbetet kan minska blandtjänstemännen vid  ett fullständigtinförande av den mobila portalen eftersom att vissa led försvinner när detgäller bland annat arbetsordrar och registrering. Jag kan konstatera att enförbättrad och förenklad version av applikationslösningen krävs för att få ettfullständigt införande bland hantverkarna..

The purpose of this study is to examine how participants perceive virtual agents shown on a computer display. In particular, it is explored to what extent participants transfer gender and attraction stereotypes that are commonly applied in the physical world to virtual agents. Previous related studies have often explored only text or voice interfaces, without any visually appearing agents, and here indeed found evidence for a transfer of gender stereotypes. Our hypothesis was that the addition of a visual agent interface would reinforce this effect. The results support our hypothesis that participants transfer human gender and attraction stereotypes onto virtual agents, as well as that these processes are affected by the visual representations of the agents..

The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

We are getting smarter. Our knowledge of the world around us is increasing rapidly and our population spend a big portion of their time in school studying it. But art and craft are moving out to give room for more theoretical subjects. Today many of us can not even fix a torn shirt without help. We buy new ones, they are cheap enough.

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.
