  1. 16. Delayed Development of Visuomotor Capacity in Very Preterm Infants

    Författare :Katarina Strand Brodd; Uwe Ewald; Gerd Holmström; Bo Strömberg; Claes von Hofsten; Louise Rönnqvist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preterm infants; visual development; neurosensory development; smooth pursuit eye movements; perinatal risk factors; reaching movements; Paediatric medicine; Pediatrisk medicin; Pediatrik; Pediatrics;

    Sammanfattning : To coordinate visual perception and motor control in daily life where we are constantly surrounded by motion, we are dependent on normal visuomotor capacity. One essential prerequisite for normal visuomotor capacity is smooth pursuit eye movements (SP). Infants born very preterm (VPT = born .. LÄS MER

  3. 17. Anticipation and Attention in Robot Control

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; eye-movements; visual field; tracking; occlusion; cognitive modelling; boebot; e-puck; color tracking; multi-agent; epistemic action; architecture; agent; robot; anticipation; attention; prediction;

    Sammanfattning : Anticipatory and predictive models are becoming very important features of robot systems. This thesis investigates some aspects of predictive modeling. LÄS MER

  4. 18. Transport mobility for children and adolescents with cerebral palsy (CP)

    Författare :Torbjörn Falkmer; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Child; adolescents; cerebral palsy; public health; legislation; prevalence; mobility; transport; risk; driving; education; eye movements; screening; visual perception; test;

    Sammanfattning : Background: The transport mobility of children and adolescents with cerebral palsy (CP) is of vital interest for the individual, as well as for society. Enhanced transport mobility can be related to improved functional health status and a higher degree of autonomy, which in turn may reduce the demand for societal support. LÄS MER

  5. 19. Biases in Visual Selective Attention : Trait Anxious Individuals Avert Their Gaze From Unpleasant Stimuli

    Författare :Jean-Christophe Rohner; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; eye-movements; attentional biases; Anxiety; attention; Psykologi;

    Sammanfattning : Cognitive models of anxiety postulate that anxious individuals are inclined to pay more attention to negative than to positive emotional visual stimuli. The main aim of the present dissertation was to test this prediction, employing a measure of the direction of gaze. LÄS MER

  7. 20. Off-line Foveated Compression and Scene Perception: An Eye-Tracking Approach

    Författare :Marcus Nyström; Humanistlaboratoriet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gaze prediction; off-line foveation; scene perception; eye-tracking; compression;

    Sammanfattning : With the continued growth of digital services offering storage and communication of pictorial information, the need to efficiently represent this information has become increasingly important, both from an information theoretic and a perceptual point of view. There has been a recent interest to design systems for efficient representation and compression of image and video data that take the features of the human visual system into account. LÄS MER
