Från ax till limpa : Verksamhetsprocessen vid framtagande av applikationer till handdatorer på Fazer Bageri AB

Human Computer Interaction (HCI) is a broad discipline that studies different concerns regarding interactive systems? development. One of the major interest points within the discipline is the reasoning behind building specific functionality into Computers and the long-term effects that usage of systems will have on humans.Within Human Computer Interaction there are theories and frameworks how to involve a user in the process of developing new systems. In this paper focus is applied to the development process within developing applications for Enterprice Digital Assistants (EDA) and to what extent the end-users are involved in the process. Fazer Bageri AB has been choosen to represent a business corporation that uses handheld Computers in their everyday tasks.The method used to gather information for this study has been by performing interviews and observations with key stakeholders at Fazer Bageri AB and MobiOne AB.

Visualisering av augmented reality i byggbranschen

Augmented reality is a technology thatcombines the perception and interaction ofvirtual objects with the real world. Itcan allow a user to visually see Computergenerated models and informationinteracting with the real world through ahand held device such as a tabletComputer. This opens up a range ofpossibilities, especially in theconstruction sector. A construction siteis permanently changing and the need forprecise and updated information iscrucial. The ability to enhance the realworld with virtual objects and informationmay make many plans printed on paperabsolete.This report describes how workers in theconstruction sector would benefit fromusing augmented reality on a tablet innumerous situations and the technologyneeded to achieve AR on a tablet.

Digital Materia

Med tankar från pedagogen Montessori och filosoferna Platon och Baudrillard har detta arbete behandlat frågor om datorn och dess betydelse för en grafiker. Frågeställningen formulerades efter hand och lydde tillslut: ?Hur kan materia te sig i digital form?? Forskningen resulterade i en hypotes för hur digital materia skulle födas i datorn: genom att blanda två uppsättningar av data, såsom två genuppsättningar tillsammans skapar en ny organism. Under produktionen utvecklades därmed en metod för hur en grafiker ska kunna skapa tillsammans med en dator. Syftet är att ge andra grafiker ett nytt sätt att se på digital grafik.

När spelen blev farliga: konstruktionen av dataspel som ett socialt problem i svensk press 2000-2006

This essay focuses on the construction of so called "Computer game addiction" or "Computer game abuse" in the Swedish press during 2000-2006. During this period Computer game addiction went from an obscure phenomenon to a legit reason for the involuntary commitment of a fourteen-year-old.The study's theory is based on several social constructionist ideas. Kitsuse and Spector's theories about constructing social problems as claims-making activities are used for understanding the actions of the individual and groups involved. Hewitt and Hall's article about quasi-theory is used to explain the construction of explainations for the new social phenomenon. Blumer's five-stage model is used for categorizing the construction of the new social problem.

Förstår du vad jag menar? - En undersökning om kommunikation med hjälp av bilder mellan användare och systemutvecklare.

Ibland kan det förkomma problem mellan utvecklare och kund/användare då de tar fram kraven till ett nytt system. En anledning till detta kan vara att utvecklingsgruppen och användargruppen inte har samma kunskaper och erfarenheter och talar då inte "samma språk". En lösning till detta problem kan vara att ta hjälp av en mockup. En mockup är en fysisk och/eller interaktiv modell av ett gränssnitt. I detta arbete har vi, med hjälp av intervjuer och observationer, undersökt om detta hjälpmedel underlättar kommunikationen i verkligheten..

Persona : En metod att utveckla och införa persona i en organisation

AbstractIn this thesis we aim to extend the current theories about a concept called persona. A persona is a model of a user, mostly based on qualitative research and made with such accuracy that it to some extent can be used as a replacement of a real user in a development process and as a communicative tool. We will present a way of constructing this persona without meeting the actual users and follow up with interviews from the organization using them. This will lead to a model over the process of introducing personas as a concept in an organization,previously not familiar with the concept. The model is adapted to also work for projects and organizations where the concept is already known..

Persuasiva spel: Ett medium med spännande möjligheter : Procedurell retorik i två svenska opinionsbildande datorspel

This essay is about the principles and rules that control persuasive Computer games. The term persuasive games mean Computer games, video games and other similar artifacts that are produced to shape opinion. The rhetorical scholar Ian Bogost at Georgia Tech claims that this kind of games mainly get their persuasive power by using procedural rhetoric and that games as a medium gives special conditions for procedurality.  By procedural rhetoric Bogost means an argumentation that is based on rules and choices, as opposed to texts, movies and images. (Bogost 2007). Bogost describes these procedures as quite specific for games and claims that they differ qualitatively from ?ordinary? rhetorical arguments even if they just as other arguments work by establishing enthymems.

The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.

Språklig utveckling : Pedagogers arbete med språklig medvetenhet och språklig stimulering

The aim of my study is to investigate if and in that case how the writing process and texts written by students in the upper secondary school are affected by the writing tool; does it matter if they write their texts on a Computer or by longhand? Another objective is to compare such an effect with the findings of previous studies performed on earlier generations of writers. The first part of my study was a survey. It showed that two thirds of the 67 students participating thought that they would have written better texts in the national writing test if they had been able to use Computers. In the second part of the study each of the fourteen participants wrote one text on Computer and another by hand.

Mobilt internet för skogsbruket med CDMA2000 i450 MHz - bandet :

Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.
