  1. 1. Embodied Pedagogical Agents: From Visual Impact to Pedagogical Implications

    Författare :Magnus Haake; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; masculinity; role modelling; cognitive styles; stereotypes; education; pedagogical implications; visual style; virtual characters; visual design; Virtual pedagogical agents; femininity; gender; androgynities;

    Sammanfattning : Embodied pedagogical agents – visually represented, computer generated characters in pedagogical roles, such as virtual instructors, mentors and learning companions – populate the digital society in increasing numbers. They are found in educational programmes from preschool to university, as well as in broader educational contexts in the form of medical counsellors, virtual health coaches, information guides, etc. LÄS MER

  3. 2. Modelling appearance printing : Acquisition and digital reproduction of translucent and goniochromatic materials

    Författare :Alina Pranovich; Daniel Nyström; Sasan Gooran; Jeppe Revall Frisvad; Sergiy Valyukh; Peter Stefan Nussbaum; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material appearance; 3D printing; Goniochromatism; Translucency;

    Sammanfattning : Colour perception is fundamental to our everyday experiences, allowing us to communicate and interpret visual information effectively. Yet, replicating these experiences accurately poses a significant challenge, particularly in the context of full-colour 3D printing. LÄS MER

  4. 3. Graphic Representation and Visualisation as Modelling Support for the Knowledge Acquisition Process

    Författare :Anne Håkansson; Andreas Hamfelt; Harald Kjellin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Artficial Intelligence; Knowledge-Based Systems; Knowledge Acquisition; Graphic Representation; Visualisation; Unified Modelling Language; Modelling Rule-based Systems; Visual programming; Declarative Programming; Information Networks; User-Centered Design; Knowledge Interface; Datavetenskap; Computer science; Datavetenskap; datalogi; Computer Science;

    Sammanfattning : The thesis describes steps taken towards using graphic representation and visual modelling support for the knowledge acquisition process in knowledge-based systems – a process commonly regarded as difficult. The performance of the systems depends on the quality of the embedded knowledge, which makes the knowledge acquisition phase particularly significant. LÄS MER

  5. 4. Bird Vision: Spatial acuity and colour discrimination in bright and dim light

    Författare :Olle Lind; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal vision; Visual ecology; Colour vision; Spatial acuity; Spatial contrast sensitivity; Dim light; Visual modelling; Behavioural experiments; Birds; Psittaciformes;

    Sammanfattning : Birds use vision to guide navigation, foraging and mate choice, and studies of the limitations in bird visual perception are most helpful for the understanding of bird ecology. Here, I present four studies of bird vision in bright and dim light. LÄS MER

  7. 5. Whiteness and Fluorescence in Paper : Perception and Optical Modelling

    Författare :Ludovic Gustafsson Coppel; Per Edström; Håkan Olin; Caisa Johansson; Markku Hauta-Kasari; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paper Whiteness; Fluorescence Whitening Agents; Kubelka-Munk; light scattering; paper industry applications; Colour Appearance Models; CIECAM02; Monte Carlo; Optics; Optik;

    Sammanfattning : This thesis is about modelling and predicting the perceived whiteness of plain paper from the paper composition, including fluorescent whitening agents. This includes psycho-physical modelling of perceived whiteness from measurable light reflectance properties, and physical modelling of light scattering and fluorescence from the paper composition.
