Abstract

This doctoral dissertation consists of a summary and five articles published in scientific journals. Each of the publications describes an experiment that deals with measuring and modeling different aspects of visual perception and user experience. The first experiment concentrated on measuring and modeling the relationships between the properties of photographic images and the colorperceptions that they evoke in varying viewing conditions. The results support the feasibility of using color appearance modeling for automatically adapting the output of self-luminous displaysto varying ambient lighting conditions, to maintain the perceived colors approximately constant despite illumination-induced shifts in the adaptation state of the viewer's visual system. Three of the experiments compared product or service variants in different application areas in terms of their visually perceived attributes and relevant user experience dimensions. A psychometric experiment showed how different material choices and printing techniques affected the visual attributes of printed point-of-purchase displays and contributed to the mental impressions that consumers associated with the displays. A multipart experiment that compared the experiences of reading narrative stories either digitally from a tablet device or from a printed book found differences in the mental impressions that the participants associated with the two reading platforms generally. However, the overall results of the study suggest that digital book reading experiences on tablet devices are not considerably worse than printed book reading experiences,in contrast to some earlier studies and the preconceptions of the participants of our study. Another multipart experiment compared reading experiences of different digital news publication designsand a printed newspaper, examining the relevant news reading dimensions affected by visual design choices. The study identified two distinct groups of readers, with different news readingstyles and preferences of digital news service designs. The fifth study introduced and tested a graphical data collection method for assessing perceived attributes of products, services, and concepts in web surveys. Considerably lower drop-out rate was achieved with the proposed ratingscale than with a conventional text-based survey. Common to all five experiments is the experience mapping approach that seeks to model and describe the relationships between different properties of products and services, their visually perceived attributes and the experiences that they evoke.The experiments suggest that in specific cases it is feasible to use the experience mapping approach directly to guide the iterative design process, by changing the properties of the product or serviceto shift user perceptions and experiences in the desired direction. Generally, however, the relationships between concrete design variables, perceived attributes, and user experience dimensions become so complex that considerable designer discretion and expertise is still needed to mold the user experience of a product or service in the desired way.
