    Typografiska riktlinjer och textframställning för smartphones2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This research focuses on the issue of how to best structure text on a Smartphone screen. The factors involved in this research are text size, white space, text and line lengths, serif and sans serif fonts, pictures in text and contrast.  The methodology of our research is based on a normative Swedish able-bodied person, as well as on relevant literature, personal analyses, interviews with people in the trade, an online survey, and a test performed with a focus group. The results are that a text written for Smartphones is best structured with: several paragraph divisions made with blank lines, with pictures where the picture has an informational purpose, and text length based on category of subject. The picture should be placed above the body text. Longer texts should be set with a scroll-function. Contrast is of great importance on mobile phones as texts can be read properly even when set in negative. In addition, using serif or sans serif is of no importance. According to the results both serif and sans serif can be read without difficulties on a Smartphone. Text size should be slightly enlarged in relation to the default settings on the mobile device. Since word division is not supported on screen, short words are recommended when possible to prevent a highly uneven right end.

    Evaluation of a versatile energy auditing tool2016Conference paper (Refereed)
    Abstract [en]

    Energy auditing can be an important contribution for identification and assessment of energy conservation measures (ECMs) in buildings. Numerous tools and software have been developed, with varying degree of precision and complexity and different areas of use.

     

    This paper evaluates PHPP as a versatile, easy-to-use energy auditing tool and gives examples of how it has been compared to a dynamic simulation tool, within the EU-project iNSPiRe. PHPP is a monthly balance energy calculation tool based on EN13790. It is intended for assisting the design of Passive Houses and energy renovation projects and as guidance in the choice of appropriate ECMs.

     

    PHPP was compared against the transient simulation software TRNSYS for a single family house and a multi-family house. It should be mentioned that dynamic building simulations might strongly depend on the model assumptions and simplifications compared to reality, such as ideal heating or real heat emission system. Setting common boundary conditions for both PHPP and TRNSYS, the ideal heating and cooling loads and demands were compared on monthly and annual basis for seven European locations and buildings with different floor area, S/V ratio, U-values and glazed area of the external walls.

     

    The results show that PHPP can be used to assess the heating demand of single-zone buildings and the reduction of heating demand with ECMs with good precision. The estimation of cooling demand is also acceptable if an appropriate shading factor is applied in PHPP. In general, PHPP intentionally overestimates heating and cooling loads, to be on the safe side for system sizing. Overall, the agreement with TRNSYS is better in cases with higher quality of the envelope as in cold climates and for good energy standards. As an energy auditing tool intended for pre-design it is a good, versatile and easy-to-use alternative to more complex simulation tools.

    Live-action communication design: a technical how-to video case study2019In: Technical Communication Quarterly, ISSN 1057-2252, Vol. 28, no 1, p. 69-91Article in journal (Refereed)
    Abstract [en]

    This case study is based on a research through design project (RTD) thatfocuses on a technical communication video of the live-action format. Itinvestigates the usability and design-implications of a live-action how-tovideo, by means of analyzing user-centered data such as YouTube analyticsdata, usability, and comprehension assessments. In the study, four key liveactionvideo affordances are identified: verifiability, comparability, recordability,and visibility. The identification of these affordances when related tothe users’ assessments resulted in several design implementations thatwould warrant sought-for communication efficacies. Findings show thatsome assumed efficacies appear to be mitigated by the complexity andthe density of the video information. One implication of this is that theimplementation of conventional video editing techniques and the additionof on-screen text that serve to make content briefer and more concise intoinstructional live-action videos requires the technical communicator’s carefulconsideration.

    ”Kunskaperna gömmer sig lite i roliga gubbar”: Pedagogers syn på iPadsanvändning som en del av matematikundervisningen i förskoleklass och årskurs 1-32013Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med detta arbete är att få kunskap om hur pedagoger i förskoleklass samt årskurserna 1-3 som har tillgång till iPads i sin matematikundervisning ser på användandet av dessa. Hur resonerar pedagoger när de använder iPadsen och finns det en tanke bakom hur iPadsen används när det gäller matematiska mål i Lgr 11? Metoden som användes för att få svar på frågeställningarna var dels en enkätundersökning för att nå ut till många pedagoger och därefter fördjupande intervjuer som baserade på enkätfrågornas resultat.
