  1. 1. Characterisation of nystagmus waveforms in eye-tracker signals

    Författare :William Rosengren; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Eye tracking; Signal processing; Nystagmus;

    Sammanfattning : This thesis deals with the analysis of eye–tracker signals recorded from nystagmus patients. Nystagmus is an eye movement disorder caused by an underlying condition, and patients who suffer from nystagmus express involuntary oscillating eye move- ments. LÄS MER

  3. 2. Gaze control in episodic memory

    Författare :Linus Holm; Timo Mäntylä; Bruno Laeng; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; psykologi; Psychology; psykologi;

    Sammanfattning : The role of gaze control in episodic recognition was investigated in two studies. In Study 1, participants encoded human faces inverted or upright, with or without eye movements (Experiment 1) and under sorting or rating tasks (Experiment 2) respectively. LÄS MER

  4. 3. Volterra Modeling and Estimation of the Human Smooth Pursuit

    Författare :Viktor Bro; Alexander Medvedev; Geoff Chase; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volterra models; Volterra-Laguerre models; Nonlinear modeling; Smooth pursuit; Eye tracking; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This thesis treats the mathematical modeling of the human smooth pursuit system using Volterra-Laguerre models. The smooth pursuit system allows for tracking of moving objects. Since it is a complex system including the muscles of the eye, nerves and certain parts of the brain, the system may be impaired if some part is compromised. LÄS MER

  5. 4. From Eye to Mind : Early Visuomotor Performance and Developmental Trajectories in Children Born Preterm

    Författare :Ylva Fredriksson Kaul; Lena Hellström-Westas; Claes von Hofsten; Kerstin Rosander; Katarina Strand Brodd; Birgitta Böhm; Audrey van der Meer; Uppsala universitet; []
    Nyckelord :Children born very preterm; Visual tracking; Reaching; Neurodevelopment; Predictive control; Attention; Cognition; Psychology; Psykologi; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Children born very preterm, at less than 32 weeks of gestation, have an increased risk of developing problems with attention, cognition, perception and motor function. Despite this, the developmental trajectories leading from preterm birth to later impairments are not fully understood. LÄS MER

  7. 5. 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
