Visualization of an Individual Carbon Footprint Mitigation Plan Using Transaction DataBrånemark, Beatrice January 2021 (has links)
Achieving the objectives of the Paris Agreements requires actions being taken on different fronts. This study looked into how to visualize a carbon footprint mitigation plan for individuals. The research consisted of designing and implementing a prototype containing visualization of a mitigation plan in the Swedish mobile app DO, a newer type of carbon calculator that uses transaction data to estimate the users' carbon footprints. A user study was then conducted with app users to evaluate the visualization. Findings from the study involved that proper handling of data is important for what a mitigation plan communicates to the user, but that receiving guidance on how to proceed ahead was greatly appreciated regardless. For future research, the visualization of a mitigation plan on small screens could be developed further with the prototype developed for this study as a starting point. It was suggested that such research could revolve around interaction improvements, evaluation with more frequent users, and observing whether a mitigation plan could affect behavior change. / För att uppnå Parisavtalets mål krävs att åtgärder vidtas på olika fronter. Denna studie undersökte hur man kan visualisera en nedtrappningsplan för individers livsstilsrelaterade koldioxidavtryck. Studien bestod av utformning och implementering av en prototyp innehållande visualisering av en nedtrappningsplan i den svenska mobilappen DO, en nyare typ av koldioxidkalkylator som använder transaktionsdata för att uppskatta användarnas koldioxidavtryck. En användarstudie genomfördes sedan med appanvändare för att utvärdera visualiseringen. Resultaten från studien belyste att ordentlig hantering av data är avgörande för vad en nedtrappningsplan kommunicerar till användaren, men att få vägledning om vägen framåt var uppskattat oavsett. För framtida forskning kan visualisering av en nedtrappningsplan på små skärmar utvecklas vidare med prototypen utvecklad för denna studie som utgångspunkt. Det föreslogs att sådan forskning skulle kunna kretsa kring förbättringar av interaktionen, utvärdering med mer frekventa användare och att observera huruvida en nedtrappningsplan kan påverka beteendeförändringar.

Comparing the Readability of Text Displays on Paper, E-Book Readers, and Small Screen DevicesBaker, Rebecca Dawn 05 1900 (has links)
Science fiction has long promised the digitalization of books. Characters in films and television routinely check their palm-sized (or smaller) electronic displays for fast-scrolling information. However, this very technology, increasingly prevalent in today's world, has not been embraced universally. While the convenience of pocket-sized information pieces has the techno-savvy entranced, the general public still greets the advent of the e-book with a curious reluctance. This lack of enthusiasm seems strange in the face of the many advantages offered by the new medium - vastly superior storage capacity, searchability, portability, lower cost, and instantaneous access. This dissertation addresses the need for research examining the reading comprehension and the role emotional response plays in the perceived performance on e-document formats as compared to traditional paper format. This study compares the relative reading comprehension on three formats (Kindle, iTouch, and paper) and examines the relationship of subject's emotional response and relative technology exposure as factors that affect how the subject perceives they have performed on those formats. This study demonstrates that, for basic reading comprehension, the medium does not matter. Furthermore, it shows that, the more uncomfortable a person is with technology and expertise in the requested task (in this case, reading), the more they cling to the belief that they will do better on traditional (paper) media - regardless of how well they actually do.
