In visualization problems, surface shape is often a piece of data that must be shown effectively. One factor that strongly affects shape perception is texture. For example, patterns of texture on a surface can show the surface orientation from foreshortening or compression of the texture marks, and surface depth through size variation from perspective projection. However, texture is generally under-used in the scientific visualization community. The benefits of using texture on single surfaces also apply to layered surfaces. Layering of multiple surfaces in a single viewpoint allows direct comparison of surface shape. The studies presented in this dissertation aim to find optimal methods for texturing of both single and layered surfaces. This line of research starts with open, many-parameter experiments using human subjects to find what factors are important for optimal texturing of layered surfaces. These experiments showed that texture shape parameters are very important, and that texture brightness is critical so that shading cues are available. Also, the optimal textures seem to be task dependent; a feature finding task needed relatively little texture information, but more shape-dependent tasks needed stronger texture cues.

Att tal uppfattas audiovisuellt, både med hörseln och med synen, tas fasta på i de kommunikationsråd som ges till personer med hörselnedsättningar och deras anhöriga. Syftet med denna uppsats är att utröna om det finns vetenskapliga belägg för att visuell information bidrar till att öka taluppfattningsförmågan hos vuxna, sensorineuralt hörselskadade. Metoden har innefattat en litteratursökning i databaser tillgängliga via Örebro Universitetsbibliotek och en urvalsprocess baserad på vissa inkluderingsrespektive exkluderingskriterier samt kvalitetsgranskning av litteratur. Resultatet visar att det finns vetenskapliga belägg för att visuell information bidrar till en ökad taluppfattningsförmåga. Resultatet diskuteras bland annat utifrån dess generaliserbarhet till verkliga kommunikationssituationer.

When studying how companies differentiate from their competitors, corporate image can play a main role in this aspect. The aim of this study is to observe and analyse the perception by the consumers of the corporate image of two groceries companies.This perception can lead to a competitive position in the marketplace by outperforming competitors in all the areas of corporate image. Thus, it can be observed how both companies are differentiated in the mind of the consumers in a different way.
