  1. 11. Evaluation of the infrared reflection method for saccadic eye movement velocity analysis

    Författare :Frank Träisk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Infrared reflection; Scleral search coil; Saccade; Main sequence; Eye-tracking.;

    Sammanfattning : Saccades are rapid eye movements that change the orientation of the eyes onto objects of interest. In an every day situation saccadic eye movements are used for e.g. reading, scanning objects and enviromnents. LÄS MER

  3. 12. Breast Tomosynthesis: Aspects on detection and perception of simulated lesions

    Författare :Pontus Timberg; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The aim of this thesis was to investigate aspects on detectability of simulated lesions (microcalcifications and masses) in digital mammography (DM) and breast tomosynthesis (BT). Perception in BT image volumes were also investigated by evaluating certain reading conditions. LÄS MER

  4. 13. Transverse Chromatic Aberration and Vision: Quantification and Impact across the Visual Field

    Författare :Simon Winter; Linda Lundström; Stephen Burns; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transverse chromatic aberration; lateral chromatic aberration; visual optics; peripheral vision; central vision; dispersion; ophthalmic optics and devices; optical effects on vision; retinal imaging; myopia; human eye; Fysik; Physics;

    Sammanfattning : The eye is our window to the world. Human vision has therefore been extensively studied over the years. However, in-depth studies are often either limited to our central visual field, or, when extended to the periphery, only correct optical errors related to a narrow spectrum of light. LÄS MER

  5. 14. Joint Attention in Development : Insights from Children with Autism and Infant Siblings

    Författare :Emilia Thorup; Terje Falck-Ytter; Gustaf Gredebäck; Peter Mundy; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Autism Spectrum Disorder; Joint Attention; Gaze following; Alternating gaze; Social cognition; Eye tracking; Infant siblings; Psychology; Psykologi;

    Sammanfattning : Compared to other children, children with Autism Spectrum Disorder (ASD) are known to engage less in joint attention - the sharing of attention between two individuals toward a common object or event. Joint attention behaviors - for example gaze following, alternating gaze, and pointing - play an important role in early development, as they provide a foundation for learning and social interaction.

  7. 15. Wavefront Aberrations and Peripheral Vision

    Författare :Linda Lundström; Peter Unsbo; Austin Roorda; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optics; Human eye; Aberrations; Peripheral vision; Central visual field loss; Optics; Optik;

    Sammanfattning : Failing eyesight causes a dramatic change in life. The aim of this project is to help people with large central visual field loss to better utilize their remaining vision. Central visual field loss means that the person has to rely on peripheral vision since the direct vision is lost, often due to a dysfunctional macula. LÄS MER
