1	The Value of Redesigning Visualization Tools : A case study on carbon emissions data / Värdet i att omarbeta visualiseringsverktyg : En fallstudie på utsläppsdata Jakobsson, Louise January 2021 (has links) Organizations can reduce carbon emissions by collecting data on what their emissions are and replace activities that are emission dense. To aid exploration, emission data can be visualized using a data visualization tool. A basic principle of designing a data visualization tool is the Visual Information Seeking Mantra (VISM): Overview first, zoom and filter, then details-on-demand. The company Measure & Change, which created a tool automating the retrieval and calculation of an organization’s emission data, has also designed a visualization tool for exploring such data. However, this tool was not created with the VISM in mind. This thesis discusses and evaluate (1) How can the data visualization tool be optimized using the design principle of Overview first, zoom and filter, details-on-demand? and (2) What is the impact of re-designing the data visualization tool in such a way? Through analysis of the dataset, user tasks, and the Visual Information Seeking Mantra, a new prototype was created. Both prototypes were then evaluated in A/B tests, with thinking aloud, a semi-structured interview, and the standardized ICE-T survey. The results suggest that the changes improved the tool, and that the user value increased. The ICE-T scores put the old implementation at 4.7, and the new prototype at 6. Visualizations scoring 5 or higher are generally accepted as valuable.

2	Visualization of live search / Visualisering av realtidssök Nilsson, Olof January 2013 (has links) The classical search engine result page is used for many interactions with search results. While these are effective at communicating relevance, they do not present the context well. By giving the user an overview in the form of a spatialized display, in a domain that has a physical analog that the user is familiar with, context should become pre-attentive and obvious to the user. A prototype has been built that takes public medical information articles and assigns these to parts of the human body. The articles are indexed and made searchable. A visualization presents the coverage of a query on the human body and allows the user to interact with it to explore the results. Through usage cases the function and utility of the approach is shown. search technology search engine information retrieval live search query completion facet recall precision machine learning document classification linear classifier document categorization document clustering multi-label classification labelling hamming loss f-score visualization information visualization distance-similarity metaphor spatialized display visual information-seeking mantra user interface spatialization document processing Interaction Technologies Interaktionsteknik Computer Sciences Datavetenskap (datalogi) Information Systems Human Computer Interaction
